Automating Phishing Email Triage with Microsoft Security Copilot
This blog details automating phishing email triage using Azure Logic Apps, Azure Function Apps, and Microsoft Security Copilot. Deployable in under 10 minutes, this solution primarily analyzes email intent without relying on traditional indicators of compromise, accurately classifying benign/junk, suspicious, and phishing emails. Benefits include reducing manual workload, improved threat detection, and (optional) integration seamlessly with Microsoft Sentinel – enabling analysts to see Security Copilot analysis within the incident itself. Designed for flexibility and control, this Logic App is a customizable solution that can be self-deployed from GitHub. It helps automate phishing response at scale without requiring deep coding expertise, making it ideal for teams that prefer a more configurable approach and want to tailor workflows to their environment. The solution streamlines response and significantly reduces manual effort. Access the full solution on the Security Copilot Github: GitHub - UserReportedPhishing Solution. For teams looking for a more sophisticated, fully integrated experience, the Security Copilot Phishing Triage Agent represents the next generation of phishing response. Natively embedded in Microsoft Defender, the agent autonomously triages phishing incidents with minimal setup. It uses advanced LLM-based reasoning to resolve false alarms, enabling analysts to stay focused on real threats. The agent offers step-by-step decision transparency and continuously learns from user feedback. Read the official announcement here. Introduction: Phishing Challenges Continue to Evolve Phishing continues to evolve in both scale and sophistication, but a growing challenge for defenders isn't just stopping phishing, it’s scaling response. Thanks to tools like Outlook’s "Report Phishing" button and increased user awareness, organizations are now flooded with user-reported emails, many of which are ambiguous or benign. This has created a paradox: better detection by users has overwhelmed SOC teams, turning email triage into a manual, rotational task dreaded for its repetitiveness and time cost, often taking over 25 minutes per email to review. Our solution addresses that problem, by automating the triage of user-reported phishing through AI-driven intent analysis. It's not built to replace your secure email gateways or Microsoft Defender for Office 365; those tools have already done their job. This system assumes the email: Slipped past existing filters, Was suspicious enough for a user to escalate, Lacks typical IOCs like malicious domains or attachments. As a former attacker, I spent years crafting high-quality phishing emails to penetrate the defenses of major banks. Effective phishing doesn't rely on obvious IOCs like malicious domains, URLs, or attachments… the infrastructure often appears clean. The danger lies in the intent. This is where Security Copilot’s LLM-based reasoning is critical, analyzing structure, context, tone, and seasonal pretexts to determine whether an email is phishing, suspicious, spam, or legitimate. What makes this novel is that it's the first solution built specifically for the “last mile” of phishing defense, where human suspicion meets automation, and intent is the only signal left to analyze. It transforms noisy inboxes into structured intelligence and empowers analysts to focus only on what truly matters. Solution Overview: How the Logic App Solution Works (and Why It's Different) Core Components: Azure Logic Apps: Orchestrates the entire workflow, from ingestion to analysis, and 100% customizable. Azure Function Apps: Parses and normalizes email data for efficient AI consumption. Microsoft Security Copilot: Performs sophisticated AI-based phishing analysis by understanding email intent and tactics, rather than relying exclusively on predefined malicious indicators. Key Benefits: Rapid Analysis: Processes phishing alerts and, in minutes, delivers comprehensive reports that empower analysts to make faster, more informed triage decisions – compared to manual reviews that can take up to 30 minutes. And, unlike analysts, Security Copilot requires zero sleep! AI-driven Insights: LLM-based analysis is leveraged to generate clear explanations of classifications by assessing behavioral and contextual signals like urgency, seasonal threats, Business Email Compromise (BEC), subtle language clues, and otherwise sophisticated techniques. Most importantly, it identifies benign emails, which are often the bulk of reported emails. Detailed, Actionable Reports: Generates clear, human-readable HTML reports summarizing threats and recommendations for analyst review. Robust Attachment Parsing: Automatically examines attachments like PDFs and Excel documents for malicious content or contextual inconsistencies. Integrated with Microsoft Sentinel: Optional integration with Sentinel ensures central incident tracking and comprehensive threat management. Analysis is attached directly to the incident, saving analysts more time. Customization: Add, move, or replace any element of the Logic App or prompt to fit your specific workflows. Deployment Guide: Quick, Secure, and Reliable Setup The solution provides Azure Resource Manager (ARM) templates for rapid deployment: Prerequisites: Azure Subscription with Contributor access to a resource group. Microsoft Security Copilot enabled. Dedicated Office 365 shared mailbox (e.g., phishing@yourdomain.com) with Mailbox.Read.Shared permissions. (Optional) Microsoft Sentinel workspace. Refer to the up to date deployment instructions on the Security Copilot GitHub page. Technical Architecture & Workflow: The automated workflow operates as follows: Email Ingestion: Monitors the shared mailbox via Office 365 connector. Triggers on new email arrivals every 3 minutes. Assumes that the reported email has arrived as an attachment to a "carrier" email. Determine if the Email Came from Defender/Sentinel: If the email came from Defender, it would have a prepended subject of “Phishing”, if not, it takes the “False” branch. Change as necessary. Initial Email Processing: Exports raw email content from the shared mailbox. Determines if .msg or .eml attachments are in binary format and converts if necessary. Email Parsing via Azure Function App: Extracts data from email content and attachments (URLs, sender info, email body, etc.) and returns a JSON structure. Prepares clean JSON data for AI analysis. This step is required to "prep" the data for LLM analysis due to token limits. Click on the “Parse Email” block to see the output of the Function App for any troubleshooting. You'll also notice a number of JSON keys that are not used but provided for flexibility. Security Copilot Advanced AI Reasoning: Analyzes email content using a comprehensive prompt that evaluates behavioral and seasonal patterns, BEC indicators, attachment context, and social engineering signals. Scores cumulative risk based on structured heuristics without relying solely on known malicious indicators. Returns validated JSON output (some customers are parsing this JSON and performing other action). This is where you would customize the prompt, should you need to add some of your own organizational situations if the Logic App needs to be tuned: JSON Normalization & Error Handling: A “normalization” Azure Function ensures output matches the expected JSON schema. Sometimes LLMs will stray from a strict output structure, this aims to solve that problem. If you add or remove anything from the Parse Email code that alters the structure of the JSON, this and the next block will need to be updated to match your new structure. Detailed HTML Reporting: Generates a detailed HTML report summarizing AI findings, indicators, and recommended actions. Reports are emailed directly to SOC team distribution lists or ticketing systems. Optional Sentinel Integration: Adds the reasoning & output from Security Copilot directly to the incident comments. This is the ideal location for output since the analyst is already in the security.microsoft.com portal. It waits up to 15 minutes for logs to appear, in situations where the user reports before an incident is created. The solution works pretty well out of the box but may require some tuning, give it a test. Here are some examples of the type of Security Copilot reasoning. Benign email detection: Example of phishing email detection: More sophisticated phishing with subtle clues: Enhanced Technical Details & Clarifications Attachment Processing: When multiple email attachments are detected, the Logic App processes each binary-format email sequentially. If PDF or Excel attachments are detected, they are parsed for content and are evaluated appropriately for content and intent. Security Copilot Reliability: The Security Copilot Logic App API call uses an extensive retry policy (10 retries at 10-minute intervals) to ensure reliable AI analysis despite intermittent service latency. If you run out of SCUs in an hour, it will pause until they are refreshed and continue. Sentinel Integration Reliability: Acknowledges inherent Sentinel logging delays (up to 15 minutes). Implements retry logic and explicit manual alerting for unmatched incidents, if the analysis runs before the incident is created. Security Best Practices: Compare the Function & Logic App to your company security policies to ensure compliance. Credentials, API keys, and sensitive details utilize Azure Managed Identities or secure API connections. No secrets are stored in plaintext. Azure Function Apps perform only safe parsing operations; attachments and content are never executed or opened insecurely.

In this blog, I will walk through how you can build functions based on a Microsoft Sentinel Log Analytics workspace for use in custom KQL-based plugins for Security Copilot. The same approach can be used for Azure Data Explorer and Defender XDR, so long as you follow the specific guidance for either platform. A link to those steps is provided in the Additional Resources section at the end of this blog. But first, it’s helpful to clarify what parameterized functions are and why they are important in the context of Security Copilot KQL-based plugins. Parameterized functions accept input details (variables) such as lookback periods or entities, allowing you to dynamically alter parts of a query without rewriting the entire logic Parameterized functions are important in the context of Security Copilot plugins because of: Dynamic prompt completion: Security Copilot plugins often accept user input (e.g., usernames, time ranges, IPs). Parameterized functions allow these inputs to be consistently injected into KQL queries without rebuilding query logic. Plugin reusability: By using parameters, a single function can serve multiple investigation scenarios (e.g., checking sign-ins, data access, or alerts for any user or timeframe) instead of hardcoding different versions. Maintainability and modularity: Parameterized functions centralize query logic, making it easier to update or enhance without modifying every instance across the plugin spec. To modify the logic, just edit the function in Log Analytics, test it then save it- without needing to change the plugin at all or re-upload it into Security Copilot. It also significantly reduces the need to ensure that the query part of the YAML is perfectly indented and tabbed as is required by the Open API specification, you only need to worry about formatting a single line vs several-potentially hundreds. Validation: Separating query logic from input parameters improves query reliability by avoiding the possibility of malformed queries. No matter what the input is, it's treated as a value, not as part of the query logic. Plugin Spec mapping: OpenAPI-based Security Copilot plugins can map user-provided inputs directly to function parameters, making the interaction between user intent and query execution seamless. Practical example In this case, we have a 139-line KQL query that we will reduce to exactly one line that goes into the KQL plugin. In other cases, this number could be even higher. Without using functions, this entire query would have to form part of the plugin Note: The rest of this blog assumes you are familiar with KQL custom plugins-how they work and how to upload them into Security Copilot.

query (BEFORE creating the parameters in the UI). This will put the query in a “temporary” unusable state because the parameters will cause syntax problems in this state. However, since the plan is to run the query as a function this is ok Create the parameters in the Log Analytics UI Give the function a name and define the parameters exactly as they show up in the query in step 1 above. In this example, we are defining two parameters: lookback – to store the lookback period to be passed to the time filter and User_Dept to the user’s department. 3. Test the query. Note the order of parameter definition in the UI. i.e. first the User_Dept THEN the lookback period. You can interchange them if you like but this will determine how you submit the query using the function. If the User_Dept parameter was defined first then it needs to come first when executing the function. See the below screenshot. Switching them will result in the wrong parameter being passed to the query and consequently 0 results will be returned. Effect of switched parameters: To edit the function, follow the steps below: Navigate to the Logs menu for your Log Analytics workspace then select the function icon Once satisfied with the query and function, build your spec file for the Security Copilot plugin. Note the parameter definition and usage in the sections highlighted in red below And that’s it, from 139 unwieldy KQL lines to one very manageable one! You are welcome 😊 Let’s now put it through its paces once uploaded into Security Copilot. We start by executing the plugin using its default settings via the direct skill invocation method. We see indeed that the prompt returns results based on the default values passed as parameters to the function: Next, we still use direct skill invocation, but this time specify our own parameters: Lastly, we test it out with a natural language prompt: tment Tip: The function does not execute successfully if the default summarize function is used without creating a variable i.e. If the summarize count() command is used in your query, it results in a system-defined output variable named count_. To bypass this issue, ensure to use a user-defined variable such as Event_Count as shown in line 77 below: Conclusion In conclusion, leveraging parameterized functions within KQL-based custom plugins in Microsoft Security Copilot can significantly streamline your data querying and analysis capabilities. By encapsulating reusable logic, improving query efficiency, and ensuring maintainability, these functions provide an efficient approach for tapping into data stored across Microsoft Sentinel, Defender XDR and Azure Data Explorer clusters.

Greetings pilots, and welcome to another pioneering year of AI innovation with Security Copilot. Find out how your organization can reach new heights with Security Copilot through the many exciting announcements on the way at both Microsoft Secure and RSA 2025. This is why now is the time to familiarize yourself and get airborne with Security Copilot. Go to School Microsoft Security Copilot Flight School is a comprehensive series charted to take students through fundamental concepts of AI definitions and architectures, take flight with prompting and automation, and hit supersonic speeds with Logic Apps and custom plugins. By the end of the course, students should be equipped with the requisite knowledge for how to successfully operate Security Copilot to best meet their organizational needs. The series contains 11 episodes with each having a flight time of around 10 minutes. Security Copilot is something I really, really enjoy, whether I’m actively contributing to its improvement or advocating for the platform’s use across security and IT workflows. Ever since I was granted access two years ago – which feels like a millennium in the age of AI – it’s been a passion of mine, and it’s why just recently I officially joined the Security Copilot product team. This series in many ways reflects not only my passion but similar passion found in my marketing colleagues Kathleen Lavallee (Senior Product Marketing Manager, Security Copilot) Shirleyse Haley (Senior Security Skilling Manager), and Shateva Long (Product Manager, Security Copilot). I hope that you enjoy it just as much as we did making it. Go ahead, and put on your favorite noise-cancelling headphones, it’s time, pilots, to take flight. Log Flight Hours There are two options for watching Security Copilot Flight School: either on Microsoft Learn or via the Youtube Playlist found on the Microsoft Security Youtube Channel. The first two episodes focus on establishing core fundamentals of Security Copilot platform design and architecture – or perhaps attaining your instrument rating. The episodes thereafter are plotted differently, around a standard operating procedure. To follow the ideal flight path Security Copilot should be configured and ready to go – head over to MS Learn and the Adoption Hub to get airborne. It’s also recommended that pilots watch the series sequentially, and be prepared to follow along with resources found on Github, to maximize learning and best align with the material. This will mean that you’ll need to coordinate with a pilot with owner permissions for your instance to create and manipulate the necessary resources. Episode 1 - What is Microsoft Security Copilot? Security is complex and requires highly specialized skills to face the challenges of today. Because of this, many of the people working to protect an organization work in silos that can be isolated from other business functions. Further, enterprises are highly fragmented environments with esoteric systems, data, and processes. All of which takes a tremendous amount of time, energy, and effort just to do the day-to-day. Security Copilot is a cloud-based, AI-powered security platform that is designed to address the challenges presented by complex and fragmented enterprise environments by redefining what security is and how security gets done. What is AI, and why exactly should it be used in a cybersecurity context? Episode 2 - AI Orchestration with Microsoft Security Copilot Why is The Paper Clip Pantry a 5-star restaurant renowned the world over for its Wisconsin Butter Burgers? Perhaps it’s how a chef uses a staff with unique skills and orchestrates the sourcing of resources in real time, against specific contexts to complete an order. After watching this episode you’ll understand how AI Orchestration works, why nobody eats a burger with only ketchup, and how the Paper Clip Pantry operates just like the Security Copilot Orchestrator. Episode 3 – Standalone and Embedded Experiences Do you have a friend who eats pizza in an inconceivable way? Maybe they eat a slice crust-first, or dip it into a sauce you never thought compatible with pizza? They work with pizza differently, just like any one security workflow could be different from one task, team, or individual to the next. This philosophy is why Security Copilot has two experiences – solutions embedded within products, and a standalone portal – to augment workflows no matter their current state. This episode will begin covering those experiences. Episode 4 – Other Embedded Experiences Turns out you can also insist upon putting cheese inside of pizza crust, or bake it thick enough as to require a fork and knife. I imagine, it’s probably something Windows 95 Man would do. In this episode, the Microsoft Entra, Purview, Intune, and Microsoft Threat Intelligence products showcase how Security Copilot advances their workflows within their portals. Beyond baking in the concepts of many workflows, many operators, the takeaway from this episode is that Security Copilot works with security adjacent workflows – IT, Identity, and DLP. Episode 5 – Manage Your Plugins ource different insights across your environment. Like our chef in The Paper Clip Pantry, we should probably define what we want to cook, what chefs to use, and set permissions for those that can interact within any input or output from the kitchen. Find out what plugins add to Security Copilot and how you can set plugin controls for your team and organization. Episode 6 – Prompting Is this an improv lesson, or a baking show? Or maybe if you watch this episode, you’ll learn how Security Copilot handles natural language inputs to provide you meaningful answers know as responses. Episode 7 – Prompt Engineering With the fundamentals of prompting in your flight log, it’s time to soar a bit higher with prompt engineering. In this episode you will learn how to structure prompts in a way to maximize the benefits of Security Copilot and begin building workflows. Congrats, pilot, your burgers will no longer come with just ketchup. Episode 8 – Using Promptbooks What would it look like to find a series of prompts and run them, in the same sequence with the same output every time? You guessed it, a promptbook, a repeatable workflow in the age of AI. See where to access promptbooks within the platform, and claw back some of your day to perfect your next butter burger. Episode 9 – Custom Promptbooks You’ve been tweaking your butter burger recipe for months now. You’ve finally landed at the perfect version by incorporating a secret nacho cheese recipe. The steps are defined, the recipe perfect. How do you repeat it? Just like your butter burger creation, you might discover or design workflows with Security Copilot. With custom promptbooks you can repeat and share them across your organization. In this episode you’ll learn about the different ways Security Copilot helps you develop your own custom AI workflows. Episode 10 – Logic Apps System automation, robot chefs? Actions? What if customers could order butter burgers with the click of a button, and the kitchen staff would automatically make one? Or perhaps every Friday at 2pm a butter burger was just delivered to you? Chances are there are different conditions across your organization that when present requires a workflow to begin. With Logic Apps, Security Copilot can be used to automatically aid workflows across any system a Logic App can connect to. More automation, less mouse clicking, that’s a flight plan everyone can agree on. Episode 11 – Extending to Your Ecosystem A famed restaurant critic stopped into the The Paper Clip Pantry ordered a butter burger, and it’s now the burger everyone is talking about. Business is booming and it's time to expand the menu – maybe a butter burger pizza, perhaps a doughnut butter burger? But you’ll need some new recipes and sources of knowledge to achieve this. Like a food menu the possibilities of expanding Security Copilot’s capabilities are endless. In this episode learn how this can be achieved with custom plugins and knowledgebases. Once you have that in your log, you will be a certified Ace, and ready to take flight with Security Copilot. Take Flight I really hope that you not only learn something new but have fun taking flight with the Security Copilot Flight School. As with any new and innovative technology, the learning never stops, and there will be opportunities to log more flight hours from our expert flight crews.

By leveraging NL2KQL, a powerful framework that translates natural language into KQL queries, Security Copilot makes querying in KQL as intuitive as a conversation. In this article, we’ll explore the story behind NL2KQL, its potential to transform security operations, and why it matters for the future of cybersecurity.Azure Lighthouse support for MSSP use of Security Copilot Sentinel scenarios in Public Preview
Security Copilot support for Azure Lighthouse Sentinel use cases for managed security service provider (MSSP) tenants is now in public preview. With this support, MSSPs can purchase SCUs and attach them to the managing tenant in Azure Lighthouse and use those SCUs to run Security Copilot skills related to Microsoft Sentinel on their customer tenants via Azure Lighthouse. All the Sentinel skills available in Security Copilot will be invokable from the Azure Lighthouse tenant without the customer needing to have Security Copilot, thereby making Security Copilot available to MSSPs who manage multiple customers. Supported scenarios include querying the customer Sentinel incident, incident entities/ details, querying Sentinel workspaces, and fetching Sentinel incident query. These skills can be invoked on per customer Sentinel workspace. Managing tenants using Azure Lighthouse now can do the following, without their customers needing to provision SCUs: Use the same natural language based prompts using Sentinel skills on customer data Create custom promptbooks using Sentinel skills to automate their investigations Use Logic Apps to trigger these promptbooks While this release doesn’t support all Security Copilot skills across customer tenants for MSSPs, it is an important development on the road to full support for Security Copilot for MSSPs using Azure Lighthouse. Read on to learn more about what this means for your practice, and how to get started. What is Azure Lighthouse? Azure Lighthouse is built into the Azure portal and allows IT partners to manage multiple tenants for Azure services. It provides a unified management experience, enabling partners to view and manage resources across all their customers' Azure environments from a single pane of glass. It supports multi-customer management, meaning partners can perform actions across multiple customer tenants simultaneously. This is particularly useful for Managed Service Providers (MSPs) who need to manage resources at scale. What is changing? We are introducing Azure Lighthouse support for MSSPs to use Security Copilot on their customer tenants without requiring customers to purchase Security Compute Units (SCUs). With Azure Lighthouse support, SCUs should be purchased by a MSSP admin for use on their customer’s tenant . To get started, MSSPs can go to Azure to onboard on to Security Copilot and apply their purchased SCUs to their Azure Lighthouse subscription. In Azure Lighthouse, the MSSP needs to ensure that they have access setup to their customer’s Sentinel environment. Once the setup is completed, MSSPs can invoke Sentinel skills on the customer tenant via the Security Copilot Standalone portal and use the SCUs associated to the Azure Lighthouse subscription. MSSPs can further use custom promptbooks and logic apps to automate their workflows. In future, managed service support will continue to expand to include other skills and capabilities such as Entra, Intune and Purview skills. We will also add support to run the skills in parallel on multiple workspaces across customer tenants so that the same prompt can return the response from multiple tenants for better analysis. What other access controls are supported? As of December 2024, we now support M365 Partner Center GDAP (Granular Delegated Admin Privileges) which allows the managing tenant to operate directly in their customer’s environment using their customer’s Security Copilot tenant. M365 Partner Center GDAP: GDAP is focused on Microsoft 365 services and is available through the Partner Center. It provides more granular and time-bound access to customer workloads, addressing security concerns by offering least-privileged access. Unlike Azure Lighthouse, GDAP relationships are more specific and time-bound, with a maximum duration of two years. Partners can request and manage these relationships through the Partner Center. GDAP is designed to help partners provide services to customers who have regulatory requirements or security concerns about high levels of partner access. MSSPs can get access to customer tenants via GDAP and log into the Security Copilot standalone portal or the embedded experience to get their jobs done. The MSSP will be able to execute all the skills in Security Copilot (Entra, Defender, Purview, Intune, XDR etc.,), a full list of skills is available here as GDAP supports all these services. In this configuration, the customer is the one purchasing Security Copilot SCUs and the MSSP uses these SCUs associated to the customer tenant, rather than SCUs associated to the MSSP’s tenant. Since Entra, Defender, Purview, Intune are not supported in Azure Lighthouse, the only way for MSSPs to use Security Copilot on their customer tenant for these products is by directly logging into the customer tenant and utilizing the SCUs purchased by customers.
