Redefining identity security for the modern enterprise
Every breach has one thing in common: an identity was exploited. Attackers have learned that identity is the fastest path to lateral movement and escalation. The challenge for defenders is that today's identity landscape is vast and fragmented — spanning hybrid environments, SaaS apps, cloud platforms, and autonomous agents. Protecting it demands more than point solutions. It requires continuous visibility, proactive posture reduction, and the ability to detect and disrupt identity threats across the full attack lifecycle. Leveraging our expertise as a leader in both Identity and Access Management (IAM) and Security, our focus has been to deliver a fast, comprehensive, and increasingly autonomous approach to identity security. It is designed to continuously strengthen identity posture and help SOC teams act faster with less manual effort. Today, I am excited to announce the next set of innovations including: Reimagined Identity Security dashboard and experiences to surface identity insights Expanded protection for more elements of modern identity fabrics including non-human identities. Streamlined detections including a new identity-level risk score that can be applied directly within risk-based conditional access policies. Unified identity view & protection across Active Directory, Entra ID, IAM solutions, SaaS and Cloud – with improved at-scale identity correlations New autonomous response capabilities to further speed identity threat triage, disruption and response. Below is a deeper look at what’s new. Turning identity sprawl into clarity Security teams don’t suffer from a lack of identity data — they suffer from a lack of insight across that data. Without context, the flood of activity from various directories, SaaS platforms, cloud services, and on‑premises infrastructure simply becomes noise. Disconnected alerts, isolated accounts, and fragmented investigations make it harder, not easier, to determine what actually matters. The updated Identity security dashboard is one of the new experiences designed to help with just that. It serves as the starting point for the SOC to gain a birds eye view of their entire identity security status, surfacing critical information on the human and non-human identities from across on-premises, SaaS and cloud environments. Fueling this, and other identity security experiences within Defender, are the advancements we have made in unifying the identity inventories. First, for human users we have expanded the account correlation capabilities we released at Ignite to include SaaS and cloud accounts. This means that security professionals will have an even more comprehensive view of related accounts, their holistic posture and identity risk. Additionally, we are also introducing new, policy-based linkage to help organizations customize these connections at scale. But modern identity fabrics extend far beyond human users. To address this shift, we are also expanding identity security coverage to include a greater focus on non‑human identities. The new non‑human identity inventory helps security teams to discover, understand, and protect these critical identities within the same identity‑centric view as human accounts. Defender helps teams see the full identity fabric — not as disconnected components, but as an interconnected system — so they can reduce blind spots, prioritize exposure, and apply consistent protection across the identities attackers increasingly rely on. Expanded coverage across the modern identity fabric Staying one step ahead of attackers starts with having a better understanding of what makes you vulnerable and closing those gaps before they can be exploited. With this mission in mind, I am excited to announce a new coverage and maturity view that shows how identity infrastructure, protections, and risk actually connect across your environment. This view serves as a snapshot revealing which access paths are protected, which are exposed, and what to fix next to meaningfully reduce blast radius. Rather than treating coverage as a static checklist, this experience surfaces actionable insights that show both current status and prioritized next steps, helping teams understand not only what needs to be protected, but also how to systematically improve identity security posture over time. With this clear guidance Defender empowers SOC teams to move from fragmented awareness to confident, identity‑centric protection. This new view is powered by the native integration available out-of-the-box with Microsoft Entra ID and the dedicated sensors and connectors available for other identity components like Privilege Access Management (PAM) solutions and other identity providers. Given this, I am pleased to share that we are adding new integrations with solutions like SailPoint and CyberArk that further our commitment to bringing additional depth and coverage for more elements of modern identity landscapes within Defender. In this same vein, we're making it easier for customers to activate protections across their on-premises identity infrastructure. Today we are excited to share that the unified identity and endpoint agent is extending support for more identity infrastructure and releasing a streamlined experience for existing customers looking to migrate to the new sensor. In addition to all this we are also adding a new identity explorer experience that is designed to help security professionals uncover identity-based exposures and lateral movement paths within their organization. Leveraging the graph capabilities within Defender and a robust set of pre-defined queries, SOC teams gain new visibility into potential exposure scenarios and end-to-end attack paths. Streamlined protections and workflows across Defender and Entra Security teams need to understand how the individual role, privilege, activity and alerts for each individual account relate to the risk of the identity as a whole. To address this, we’re introducing a new unified risk score that aggregates signals across all linked accounts to calculate a single risk score for the identity. As you can see in the image above the score considers the observed activity, criticality, privilege and likelihood of compromise for each linked account and produces a single, actionable view of risk. This means analysts no longer need to decipher various alerts themselves, they can quickly prioritize investigations based on the potential impact and urgency of identity‑driven threats. But the value of this new unified risk score doesn’t stop at investigation. Entra ID customers can now leverage these new risk signals directly within their risk-based conditional access policies. This gives admins a stronger signal for access decisions, resulting in earlier prevention, detection, and response across the identity control plane. This powers the feedback loop between identity and SOC teams, ensuring that insights gained in the SOC can immediately reduce exposure across the identity fabric. Together, these advances transform identity sprawl into clarity. By automatically connecting the dots and surfacing insights instead of raw data Defender is elevating what matters most, helping security teams cut through noise, focus on true risk, and respond to identity‑based threats with greater speed and confidence. New Identity detections using novel and unique sensor capabilities Detection opportunities start with visibility and sensor capabilities and we are excited to share a new capability that significantly improves how we see identity-based attacks on Domain Controllers. We work closely with the Windows team within Microsoft and are introducing a new Event Tracking for Windows (ETW) that gives us richer insight into Kerberos activity. This allows us to safely access important ticket details that were previously hidden while the ticket was in use, without needing to break or decrypt the ticket itself. With this additional context, we can spot unusual behavior that points to forged or tampered Kerberos tickets more accurately than before. By connecting this new operating system signal directly into our identity threat detection capabilities, we unlock a unique level of protection. It also opens up new investigation and hunting scenarios for SOC analysts who want deeper visibility into Kerberos related activity. Our first detection using this new sensor capability (“Possible golden ticket attack (suspicious ticket)”) is now generally available, and further exemplifies why our strategy is so revolutionary. Previously detecting these types of attacks would require decrypting the ticket/token itself, introducing even more potential for exposure. With this ETW however we have the same visibility without the risk. We know that Identity attacks no longer stop at the perimeter. Recognizing that modern adversaries target on‑premises, hybrid, and cloud identities alike, we invested heavily in expanding also our detection capabilities across this full spectrum. In particular, we introduced new detections for emerging attack techniques targeting Entra ID as a platform. While Entra ID Protection continues to deliver broad, native protection for Entra users and identities, the core mission of Identity Threat Protection products is to go further— detecting also sophisticated post‑breach activity and lateral movements where attackers directly target the identity provider itself, often by exploiting the hybrid trust and linkage between on‑premises and cloud environments. We are excited to announce the availability of the following new detections: 4 new detections for anomalies and attacks targeting Entra ID sync application in hybrid environments 2 new detections for suspicious device registration/join across Entra and Intune 1 new detection for techniques abusing Oauth Authorization Flow for browser-based attacks, as observed in-the-wild recently (“ConsentFix”) Powering autonomous Identity Threat Protection When a security incident is unfolding, every second matters. Attackers are already operating at machine speed, and human response alone can’t keep up, which is why AI-powered capabilities are essential for detecting, triaging and remediating identity threats in time. As part of our push toward autonomous Identity Threat Protection, we’re extending Security Copilot’s agentic triage capabilities to identity. We’ve already seen the impact of outcome-driven autonomous workflows in phishing, where our agent identifies 6.5 times more malicious alerts than human analysts working alone. Today, that same capability is extending beyond phishing to include identity alerts. The new Security Alert Triage Agent autonomously evaluates high‑volume identity alerts, distinguishing true threats from noise, and surfacing clear, explainable verdicts so analysts can focus immediately on what requires action. At Public Preview, it supports triage of alert types involving password spray attempts, suspicious inbox rules associated with business email compromise (BEC), and accounts potentially compromised following a password spray attack. Learn more about Security Copilot in Defender announcements here. In parallel, we’re expanding identity takeover predictive shielding, using real‑time exposure and attack path insights to proactively harden the identity attack surface during an active incident—blocking attacker progression before high‑value identities can be compromised. Together, these capabilities shift identity defense from reactive investigation to real‑time disruption, helping security teams contain attacks faster, reduce blast radius, and stay ahead of adversaries when it matters most. At Ignite, we introduced predictive shielding, an AI-powered capability in automatic attack disruption that predicts an attacker’s next move in an active attack and applies targeted, just-in-time hardening to block them before they can pivot. Today, predictive shielding proactively hardens many of the controls attackers most often rely on to regain access, such as SafeBoot abuse and Group Policy Objects. We’ve already seen tremendous impact across our customers, including a large public university: “During a ransomware incident, Microsoft Defender’s attack disruption stopped the attack before it could progress. In parallel, predictive shielding applied Safe Boot hardening across key devices, helping protect against a common evasion tactic—rebooting endpoints into Safe Mode to try and bypass protections like disruption. Together, these layers increased our confidence and resilience during the incident.” This speed and accuracy matter because identity-based attacks now operate at massive scale, with each user tied to many accounts across the environment, making it increasingly difficult to protect every identity. We are excited to share that we’re expanding this set of just-in-time hardening actions tailored for identity-based attacks. This includes: RemoteOps hardening: restricts high-risk remote administrative operations such as RPC-based actions that attackers rely on for lateral movement and hands-on-keyboard control. Remote Registry hardening: prevents attackers from remotely modifying sensitive registry settings often used to weaken security controls or enable credential theft. What makes these controls unique is their precision: Defender shields only the specific assets at risk, rather than applying broad, organization-wide restrictions, maximizing security while minimizing business impact. Looking ahead Identity has become the foundation of access, trust, and control in modern enterprises—and the primary target for attackers. The announcements detailed throughout this blog reflect our continued commitment to advancing identity security and to helping customers stay ahead of rapidly evolving identity-based threats. We’re excited to share more throughout the week at RSA, and we look forward to partnering with customers as they continue their journey toward comprehensive, identity centric security.From signal to strategy: Closing attack paths with identity intelligence
Compromised credentials remain one of the most common entry points for attackers. In the first half of 2025 alone, identity-based attacks surged more than 32% and its estimated that 97% of them are password focused. While that scale is overwhelming, it only takes a single exposed account to give an attacker a foothold from which they can move laterally towards the critical assets they are after. At today’s attack scale, identity signals need to be connected with broader context to stop attacks earlier in the kill chain. Today we are excited to share more about how Microsoft Defender can help security professionals proactively understand how identity-related risks, like leaked credentials, relate back to critical assets, helping security professionals proactively close potential entry points before they can be exploited. Understanding leaked credentials and attack paths: Leaked credentials refer to valid usernames and passwords that have been exposed beyond their intended scope. Whether this exposure occurs as part of a data breach, phishing attack, or postings on dark web forums, the result is the same: an attacker may be using legitimate credentials to access your organization. Similarly, attack paths describe the sequence of misconfigurations, permissions, and trust relationships that an attacker can chain together to move from an initial foothold to high‑value resources. Rather than relying on a single vulnerability, attackers tend to think in graphs, following paths of least resistance to systematically escalate privileges and expand access. This makes identities the primary control plane they target and leaked credentials as an extremely common entry point. The recent Microsoft digital defense report put this into focus, stating that more than 61% of attack paths lead to a sensitive user. These user accounts have elevated privileges or access to critical resources meaning that if they were to be attacked or misused it would significantly impact the organization. Microsoft’s differentiated approach Most solutions stop at the alert and can only tell you that a password was exposed, found, or leaked. That information matters, but it is incomplete, it describes an event, not the risk. The real differentiation starts with the next question: what does this exposure mean for my environment right now. Not every exposed password creates the same level of risk. Context is what determines impact. Which identity does the password belong to? What assets can that identity access? Does that access still exists? And are those assets truly sensitive? That is why exposed password detection is a starting point, not an end state. Effective protection begins when organizations move beyond technical alerts and toward an identity-aware understanding. This shift from detection to context is where better decisions are made and where meaningful security value is created. This is why we took our identity alerts a step further, connecting these risks with broader security context to reveal how an initial identity signal can lead to sensitive users, critical assets, and core business operations. This perspective moves security beyond isolated alerts to prioritized, actionable insight that shows not just if risk exists, but how identity‑based threats could unfold and where to intervene to stop them before they have impact. In the case of leaked credentials, Microsoft continuously scans for exposed accounts across public and private breach sources. If a match is found, Microsoft’s Advanced Correlation Engine (MACE) automatically identifies the affected user within your organization and surfaces the exposure with clear severity and context. By bringing this powerful detection into Defender, teams can investigate and respond with better context, allowing leaked credentials to be evaluated alongside endpoint, email, and app activity, giving teams additional context needed to prioritize response. Additionally, for Microsoft Entra ID accounts we can go a step further validating whether the discovered credentials actually corresponds to a real, usable password for an identity in the tenant. This confirmation further reduces unnecessary noise and gives defenders an early signal - often before any malicious activity begins. Next, Microsoft Defender steps in to correlate these signals with your organization’s unique security context. Connecting the alert and associated account with other signals and like unusual authentications, lateral movement attempts, or privilege escalations, elevating the isolated alert into a complete story about any potential incidents related to that vulnerability. At the same time, Microsoft Exposure management is analyzing the same data to create a potential attack path related to the exposed credentials. By tracing permissions, consents, and access relationships, Attack Paths show exactly which routes an attacker could take and what controls will break that path. When these capabilities work together, visibility becomes action. MACE identifies who is exposed, Defender connects other signals into an incident level view and Attack Paths reveal where the attacker could go next. The result is a single, connected workflow that transforms early exposure data into prioritized, measurable risk reduction. Conclusion Leaked credentials should be treated as the beginning of a story, not an isolated event. Microsoft Defender is uniquely able to enrich security teams visibility and understanding of Identity-related threats from initial exposure to detection, risk prioritization, and remediation. This connected visibility fundamentally changes how defenders manage identity risk, shifting the focus from reacting to individual alerts to continuously reducing exposure and limiting blast radius. One leaked password doesn’t have to become a breach. With Microsoft’s identity security capabilities, it becomes a closed path, and a measurable step toward greater resilience.

Attackers don’t move in straight lines or follow predictable, sequential steps. Instead, they think in graphs, seeking the path of least resistance, surveying your environment for weak spots and then leverage legitimate connections and permissions to quietly traverse your IT landscape. Just a single compromised account can be a powerful foothold, helping an attacker bypass your other security protocols. To put this simply, while your account may not be what the attacker is looking for, it’s one step on the path to their ultimate goal. Its estimated that less than 1% of your organizational footprint is actually of interest to attackers, but 80% of organizations have at least one open attack path to these critical assets. This is why it is so critical to have a deep understanding of the connected identities, accounts and applications that make up your identity fabric. Layered identity security for the modern enterprise Identity Threat Detection and Response (ITDR) has to combine modern identity and access management (IAM) and security operations (SOC) through an integrated partnership between identity and security teams. Because of this, our vision remains focused on streamlining how these groups collaborate, breaking down siloes to unite these teams, their tools and processes. Today, I am excited to announce new enhancements to the identity security experience within Defender that will help enrich your security team’s visibility and understanding into your unique identity fabric. These new capabilities include: Account correlation links related accounts and corresponding insights to provide identity-level visibility and insights to the SOC. Coordinated response allows Defenders to take action comprehensively across connected accounts, accelerating response and minimizing the potential for lateral movement. Account correlation: Mapping the identity fabric, one account at a time. Modern identity fabrics are often complex, reflecting the reality of today’s hybrid and multi-cloud enterprise environments. To understand vulnerabilities and map potential attack paths, security teams must first decipher the relationships between identities, accounts, infrastructure, and a myriad of identity related apps and tools. But the complexity doesn’t end with the fabric itself, each identity typically consists of several related accounts. Take the identity footprint in Figure 1 above: here we see a visual representation of the accounts associated with a single user. At the top you’ll see an on-premises Active Directory (AD) account that is synced with a corresponding Entra ID account. This type of hybrid scenario is found in more than 90% of our customers as a way to allow their users to authenticate seamlessly, to both legacy on-premises environments and cloud services like Microsoft 365. In this example the user also has two other accounts, one an administrator account with elevated privileges and the other a misconfigured cloud account. Now, as I mentioned earlier, attackers will use whatever connections they can to move laterally towards their target and in this case the misconfigured cloud account puts the identity and all its accounts at risk, including the privileged admin. Defender now links accounts, privileges, and activity patterns across the components of your unique identity fabric, augmenting the powerful graph capabilities within Microsoft Sentinel to provide defenders with one trusted view into the identity’s entire footprint. Figure 2: Identity page in Microsoft Defender showing related accounts The detailed understanding of how accounts are connected helps Defender better showcase these risks at the identity level. Posture alerts and recommendations for every related account are now surfaced within a single view. But we don’t stop there: with a relational understanding of your unique identity fabric, Defender maps potential attack paths, showing how an attacker could leverage these vulnerabilities on their way to access critical assets. The easiest way to bring this value to life is using a scenario involving leaked credentials. Earlier this year we unveiled a new leaked credentials alert that extends the powerful detection from Entra to on-premises identities. Figure 4: a sample attack path showing leaked credentials as an entry point To do this Microsoft continuously scans public and private breach resources to identify leaked credentials. If a match is found, Microsoft Security Exposure Management automatically identifies the affected user and surfaces the exposure with clear severity and context. Defender then further validates and correlates that exposure, linking that account to other cross-domain security signals to detect unusual authentications or privilege escalations. These attack paths map are now expanded to show how that compromised account could be leveraged to reach other accounts and ultimately critical assets. One leaked password doesn’t have to become a breach. With Microsoft’s identity security stack, it becomes a closed path and a measurable step toward resilience showing exactly which routes an attacker could take and what controls will break that path. Turning visibility into coordinated response Just as security professionals can now see all the related alerts and posture recommendations across the accounts associated with an identity, they can also take direct action across all accounts with one action. Figure 5: Screenshot of the new "Disable user" experience in Defender Once analysts confirm that an identity is compromised, they can disable compromised identities comprehensively across providers and applications - turning previously complex, multi-portal process into a coordinated, identity-wide response. Get started today Microsoft Defender’s latest identity security enhancements empower organizations to see and understand their entire identity fabric with unprecedented clarity. By surfacing connected accounts and posture recommendations into a single view, and coordinating response actions, Defender enables security teams to better remediate identity before, during and after a breach. This holistic approach not only strengthens identity posture but also transforms response actions from isolated steps into coordinated, organization-wide defenses. With these innovations, organizations are better equipped to outpace attackers, close open paths, and build lasting resilience in an ever-evolving threat landscape. Learn more about these capabilities here and join us in San Francisco, November 17–21, or online, November 18–20, for deep dives and practical labs to help you maximize your Microsoft Defender investments and to get more from the Microsoft capabilities you already use.

Threat actors are increasingly targeting Teams chats and channels with phishing links and malicious files, making it critical for IT admins and security professionals to extend protection beyond email. Enter Microsoft Defender for Office 365, now armed with dedicated Teams protection capabilities. Microsoft Defender for Office 365 enables users to report suspicious messages, brings time-of-click scanning of URLs and files into Teams conversations, and provides rich alerts and hunting insights for SecOps teams. As a collaborative piece between Pierre Thoor, a Microsoft Security MVP, and the Defender for Office 365 Product Engineering Team, this guides with accompanying videos emphasize a proactive, user-driven approach to threat detection and response, turning everyday Teams interactions into actionable security signals for SecOps. Microsoft Defender for Endpoint End of Windows 10 Support: What Defender Customers Need to Know As of October 14, 2025, Microsoft officially ended support for Windows 10. This means that Windows 10 devices will no longer receive security or feature updates, nor technical support from Microsoft. While these devices will continue to operate, the lack of regular security updates increases vulnerability to cyber threats, including malware and viruses. Applications running on Windows 10 may also lose support as the platform stops receiving updates. Endpoint Security Policies can now be distributed via MTO's (Multi Tenant Organization) Content Distribution capability. This capability moved from Public Preview to General Availability (GA). With this capability, you can create content distribution profiles in the multi-tenant portal that allow you to seamlessly replicate existing content - such as custom detection rules and now, endpoint security policies - from a source tenant to designated target tenants. Once distributed, the content runs on the target tenant, enabling centralized control with localized execution. You can read the announcement blog for public preview, as the content shares valuable insights. (Public Preview) Streamlined connectivity support for US government environments (GCC, GCC High, DoD). Learn more in our docs. (General Availability) Isolation exclusions. The Isolation exclusions feature is now generally available. Isolation exclusions allow designated processes or endpoints to bypass the restrictions of network isolation, ensuring essential functions continue while limiting broader network exposure. Learn more in our docs. Microsoft Defender Vulnerability Management (Public Preview) Microsoft Secure Score now includes three new Attack Surface Reduction (ASR) based proactive recommendations that help organizations prevent common endpoint attack techniques including web-shell persistence, misuse of system tools, and Safe Mode based evasion. (Public Preview) You can now use CVE exceptions to exclude specific Common Vulnerabilities and Exposures (CVEs) from analysis in your environment.

Microsoft Security Blogs The new Microsoft Security Store unites partners and innovation On September 30, 2025, Microsoft announced a bold new vision for security: a unified, AI-powered platform designed to help organizations defend against today’s most sophisticated cyberthreats. But an equally important story—one that’s just beginning to unfold—is how the Microsoft Security Store is bringing this vision to life through a vibrant ecosystem of partners, developers, and innovators—all contributing together to deliver more value and security to our customers. Security Store is the gateway for customers to easily discover, buy, and deploy trusted security solutions and AI agents from leading partners—all verified by Microsoft Security product teams to work seamlessly with Microsoft Security products. Inside the attack chain: Threat activity targeting Azure Blob Storage Azure Blob Storage is a high-value target for threat actors due to its critical role in storing and managing massive amounts of unstructured data at scale across diverse workloads and is increasingly targeted through sophisticated attack chains that exploit misconfigurations, exposed credentials, and evolving cloud tactics. Investigating targeted “payroll pirate” attacks affecting US universities Microsoft Threat Intelligence has identified a financially motivated threat actor that we track as Storm-2657 compromising employee accounts to gain unauthorized access to employee profiles and divert salary payments to attacker-controlled accounts, attacks that have been dubbed “payroll pirate”. Disrupting threats targeting Microsoft Teams Threat actors seek to abuse Microsoft Teams features and capabilities across the attack chain, underscoring the importance for defenders to proactively monitor, detect, and respond effectively. Harden your identity defense with improved protection, deeper correlation, and richer context Expanded ITDR features—including the new Microsoft Defender for Identity sensor, now generally available—bring improved protection, correlation, and context to help customers modernize their identity defense.Announcing General Availability: Unified identity and endpoint sensor
This milestone streamlines the deployment of on-premises identity security by unifying our endpoint and identity protection into a single sensor, pre-installed and ready for activation on Domain Controllers running Windows Server 2019 or newer. What Is a sensor? What’s new about this version? Viewed through a cybersecurity lens, a “sensor” is a software component that monitors and protects critical infrastructure. Serving as one of the first lines of defense against threat actors, they continuously scan corporate resources for malicious activity or misconfigurations to ensure your organization remains secure. Like many security solutions, Microsoft Defender relies on sensors to gain visibility into the endpoints and on-premises identity infrastructure within your environment. The telemetry they provide — plus unmatched Microsoft Threat Intelligence — enables us to help security professionals better detect and respond to potential threats targeting their domains. Individually, the insights into the endpoints and users are extremely valuable. But when used in tandem, they provide a holistic view and protection for identity infrastructure. V3.x takes this co-existence a step further and merges the components, eliminating the need for installing and maintaining two distinct sensors. For qualifying Domain Controllers, it’s fast and simple to activate with a click of a button, optimized for performance, and is embedded within the Windows operating system. What does this mean for customers? New customers can now easily activate identity protections on critical on-premises identity infrastructure by deploying v3.x to eligible Domain Controllers in a matter of clicks. This streamlined approach reduces deployment complexity, minimizes configuration errors, and accelerates time-to-protection. It also allows security teams to focus on threat detection and response instead of managing infrastructure prerequisites. Additional benefits include: Built into the OS – The sensor is now part of Windows Server 2019 and later (with the latest cumulative update), eliminating many of the prerequisites required by earlier sensor versions. “One-click” activation – Once your domain controller is onboarded to Defender for Endpoint for Servers, enabling identity protections can be done in just a matter of clicks within the Defender portal. You no longer need to download and distribute the sensor deployment packages, installing .NET dependencies, configuring NPCAP for interoperability, or opening ports for Network Name Resolution (NNR). Increased automation – You can even enable automatic activation for all domain controllers that meet the requirements, ensuring continuous protection with zero extra effort. How to get started: Review the prerequisites listed within our documentation to determine if you are eligible to deploy v3.x If you meet all the pre-requisites, use the detailed activation guide here to activate v3.x. Once activated we recommend you opt-in to apply unified sensor Remote Procedure Call (RPC) audit tags. By applying these tag, you enable advanced identity detections that rely on RPC monitoring via the Windows Filtering Platform (WFP). This unlocks additional alerts and visibility for identity-based threats. What's next?
