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.

Understand New Sentinel Pricing Model with Sentinel Data Lake Tier
Introduction on Sentinel and its New Pricing Model Microsoft Sentinel is a cloud-native Security Information and Event Management (SIEM) and Security Orchestration, Automation, and Response (SOAR) platform that collects, analyzes, and correlates security data from across your environment to detect threats and automate response. Traditionally, Sentinel stored all ingested data in the Analytics tier (Log Analytics workspace), which is powerful but expensive for high-volume logs. To reduce cost and enable customers to retain all security data without compromise, Microsoft introduced a new dual-tier pricing model consisting of the Analytics tier and the Data Lake tier. The Analytics tier continues to support fast, real-time querying and analytics for core security scenarios, while the new Data Lake tier provides very low-cost storage for long-term retention and high-volume datasets. Customers can now choose where each data type lands—analytics for high-value detections and investigations, and data lake for large or archival types—allowing organizations to significantly lower cost while still retaining all their security data for analytics, compliance, and hunting. Please flow diagram depicts new sentinel pricing model: Now let's understand this new pricing model with below scenarios: Scenario 1A (PAY GO) Scenario 1B (Usage Commitment) Scenario 2 (Data Lake Tier Only) Scenario 1A (PAY GO) Requirement Suppose you need to ingest 10 GB of data per day, and you must retain that data for 2 years. However, you will only frequently use, query, and analyze the data for the first 6 months. Solution To optimize cost, you can ingest the data into the Analytics tier and retain it there for the first 6 months, where active querying and investigation happen. After that period, the remaining 18 months of retention can be shifted to the Data Lake tier, which provides low-cost storage for compliance and auditing needs. But you will be charged separately for data lake tier querying and analytics which depicted as Compute (D) in pricing flow diagram. Pricing Flow / Notes The first 10 GB/day ingested into the Analytics tier is free for 31 days under the Analytics logs plan. All data ingested into the Analytics tier is automatically mirrored to the Data Lake tier at no additional ingestion or retention cost. For the first 6 months, you pay only for Analytics tier ingestion and retention, excluding any free capacity. For the next 18 months, you pay only for Data Lake tier retention, which is significantly cheaper. Azure Pricing Calculator Equivalent Assuming no data is queried or analyzed during the 18-month Data Lake tier retention period: Although the Analytics tier retention is set to 6 months, the first 3 months of retention fall under the free retention limit, so retention charges apply only for the remaining 3 months of the analytics retention window. Azure pricing calculator will adjust accordingly. Scenario 1B (Usage Commitment) Now, suppose you are ingesting 100 GB per day. If you follow the same pay-as-you-go pricing model described above, your estimated cost would be approximately $15,204 per month. However, you can reduce this cost by choosing a Commitment Tier, where Analytics tier ingestion is billed at a discounted rate. Note that the discount applies only to Analytics tier ingestion—it does not apply to Analytics tier retention costs or to any Data Lake tier–related charges. Please refer to the pricing flow and the equivalent pricing calculator results shown below. Monthly cost savings: $15,204 – $11,184 = $4,020 per month Now the question is: What happens if your usage reaches 150 GB per day? Will the additional 50 GB be billed at the Pay-As-You-Go rate? No. The entire 150 GB/day will still be billed at the discounted rate associated with the 100 GB/day commitment tier bucket. Azure Pricing Calculator Equivalent (100 GB/ Day) Azure Pricing Calculator Equivalent (150 GB/ Day) Scenario 2 (Data Lake Tier Only) Requirement Suppose you need to store certain audit or compliance logs amounting to 10 GB per day. These logs are not used for querying, analytics, or investigations on a regular basis, but must be retained for 2 years as per your organization’s compliance or forensic policies. Solution Since these logs are not actively analyzed, you should avoid ingesting them into the Analytics tier, which is more expensive and optimized for active querying. Instead, send them directly to the Data Lake tier, where they can be retained cost-effectively for future audit, compliance, or forensic needs. Pricing Flow Because the data is ingested directly into the Data Lake tier, you pay both ingestion and retention costs there for the entire 2-year period. If, at any point in the future, you need to perform advanced analytics, querying, or search, you will incur additional compute charges, based on actual usage. Even with occasional compute charges, the cost remains significantly lower than storing the same data in the Analytics tier. Realized Savings Scenario Cost per Month Scenario 1: 10 GB/day in Analytics tier $1,520.40 Scenario 2: 10 GB/day directly into Data Lake tier $202.20 (without compute) $257.20 (with sample compute price) Savings with no compute activity: $1,520.40 – $202.20 = $1,318.20 per month Savings with some compute activity (sample value): $1,520.40 – $257.20 = $1,263.20 per month Azure calculator equivalent without compute Azure calculator equivalent with Sample Compute Conclusion The combination of the Analytics tier and the Data Lake tier in Microsoft Sentinel enables organizations to optimize cost based on how their security data is used. High-value logs that require frequent querying, real-time analytics, and investigation can be stored in the Analytics tier, which provides powerful search performance and built-in detection capabilities. At the same time, large-volume or infrequently accessed logs—such as audit, compliance, or long-term retention data—can be directed to the Data Lake tier, which offers dramatically lower storage and ingestion costs. Because all Analytics tier data is automatically mirrored to the Data Lake tier at no extra cost, customers can use the Analytics tier only for the period they actively query data, and rely on the Data Lake tier for the remaining retention. This tiered model allows different scenarios—active investigation, archival storage, compliance retention, or large-scale telemetry ingestion—to be handled at the most cost-effective layer, ultimately delivering substantial savings without sacrificing visibility, retention, or future analytical capabilities.Monthly news - December 2025
