ReliaQuest vs. Microsoft
GreyMatter is an agentic AI security operations platform that unifies detection, containment, investigation, and response across your entire stack, achieving threat containment in under 5 minutes. Microsoft Security Copilot is an AI assistant that augments your analysts within the Microsoft ecosystem but does not detect threats independently, investigate autonomously, or respond across your full tool stack. For enterprise security teams that need technology-agnostic, agentic AI across the full TDCIR lifecycle, GreyMatter is the stronger fit.
GreyMatter Agentic AI
Microsoft Security Copilot is an AI assistant that layers on top of Microsoft's security stack (Sentinel, Defender XDR, Entra, Intune, Purview). It provides AI-generated suggestions and summarizations but does not unify your tools into a single operational platform. Full value requires deep commitment to the Microsoft ecosystem, reducing leverage to adopt best-of-breed alternatives and concentrating renewal risk with a single vendor.
ReliaQuest GreyMatter is an agentic AI security operations platform covering detection, containment, investigation, response, CAASM, digital risk protection (DRP), data pipeline management, and phishing analysis, all unified under a single architecture. Moves your team from reactive alert handling to proactive and predictive security operations.
AI assists investigations but does not complete them. Your analysts still review, decide, and execute. Security Copilot's agents (phishing triage, alert triage, conditional access, vulnerability remediation) address defined use cases primarily within the Microsoft stack. The recently announced Security Analyst Agent expands toward autonomous investigation but its scope is bounded to Microsoft telemetry sources. Every investigation starts from scratch with no persistent memory of your team's context, heuristics, or patterns from prior sessions.
Six Agentic Teammates that leverage 200+ agent skills and 400+ AI tools, each purpose-built for core security functions. ReliaQuest GreyMatter achieves 99.4% investigation accuracy validated through a 7-standard lifecycle. Customer-controlled Agentic Memory for viewing, editing, and managing AI guidelines directly. Agentic automated response playbooks execute containment autonomously across your full stack.
No independent detection engine or rule library. Processes alerts generated by Sentinel, Defender XDR, and other Microsoft products. Microsoft's previewed Dynamic Threat Detection Agent adds supplemental threat surfacing, but detection coverage remains dependent on which Microsoft products you have deployed. Every blind spot in your detection layer passes straight through.
Fully autonomous SOC lifecycle across EDR, IAM, email, cloud, and network, achieving threat containment in under 5 minutes. Investigates and responds to 74M alerts annually, 100% by AI. 57+ open source and paid threat intelligence feeds leveraged by Agentic Teammates, turning threat data into predictive insights. The GreyMatter Mobile App enables investigation, triage, and response from anywhere.
Full value requires Sentinel, Defender XDR, Entra, Intune, and Purview. Traditional plugins provide enrichment data only. A small number of partner agents (OneTrust, Tanium, Darktrace) can execute actions within their own scope, but direct containment across your full stack is not available through a unified response surface. Investigation quality degrades outside Microsoft: non-Microsoft tools provide less context, producing shallower investigations.
250+ data sources with bidirectional APIs. GreyMatter is technology-agnostic: it integrates with your existing tools regardless of vendor, preserving your current investments rather than forcing ecosystem lock-in. Universal Translator auto-onboards custom and proprietary sources, no manual parsing or professional services required.
No independent detection rule library. Does not deploy detection logic across your stack. Detection coverage depends entirely on the Microsoft products deployed and their rule sets. Custom detection creation, exposure management, and proactive threat hunting fall to your team outside of Security Copilot's scope.
Independent detection engine: 2000+ curated rules, at-storage, at-source, and in-transit coverage. Detection Engineering Teammate autonomously tunes rules and creates custom detections, or your team can build your own using natural language. Ingests and investigates alerts from your existing vendor tools and custom rules.
Value concentrated in Microsoft-heavy environments. Non-Microsoft EDR, SIEM, identity, or cloud tools provide less context and shallower investigations. No documented native attack surface discovery or OT visibility within Security Copilot itself.
Unified visibility across IT, OT, and multi-cloud environments with multi-entity support. GreyMatter Discover maps and monitors your complete attack surface.
Backed by Microsoft's scale and distribution through M365 E5. However, Security Copilot adds an AI assistant to your existing stack without improving how those tools work together. Your detection tools, SIEM, and analyst headcount remain unchanged. You get AI-generated suggestions, not unified operations or autonomous investigation.
AI is trained on nearly two decades of operational experience across 1,300+ complex environments. Data onboarding, custom parsing, rule tuning, and custom detections included. Your team retains full operational control.
M365 E5 customers receive 400 SCUs/month per 1,000 licensed users (capped at 10,000 SCUs/month). Active SOC usage across investigations, agent runs, promptbooks, and custom workflows can consume that allotment quickly. Overage SCUs cost 6/hour. Non-E5 customers pay 4/SCU/hour provisioned. Cost scales with AI usage volume, making budgeting unpredictable.
Core platform priced per endpoint and expansion capabilities priced by scope. No token-based pricing for AI usage. At-source and in-transit detection save customers an average of 3.5M annually on SIEM dependency and 900K annually on tool fragmentation. Delivers 224% three-year ROI (Forrester TEI, 2025).
Massive distribution through the Microsoft ecosystem. However, the deeper your investment in Microsoft security products, the harder it becomes to adopt best-of-breed alternatives. Agent coverage remains narrow and Microsoft-scoped: custom detections, exposure management, proactive hunting, and cross-tool response outside Microsoft still fall to your team.
Backed by 100+ patents and 94% customer retention, with SOC 2 Type 2, ISO 27001, PCI DSS, and HIPAA certifications. FedRAMP In Process.
No persistent AI memory. Every investigation starts from scratch without carrying forward your team's context, heuristics, or learned patterns. When Security Copilot synthesizes recommendations across multiple data sources, the full intermediate steps, raw queries, and data considered are not always exposed with the same granularity as a purpose-built investigation platform. Your team may need to validate conclusions independently before acting.
Agentic Memory lets analysts view, edit, and delete the AI's operational guidelines. Hallucination risk is mitigated through Retrieval-Augmented Generation (RAG), which grounds every AI response in historical security data. Utilizes a 7-standard AI testing and validation lifecycle: expert validation, crowdsourced QA, daily statistical sampling, golden dataset testing, LLM-as-judge evaluation, transparency artifacts, and built-in safety guardrails.

7 Questions That Separate GreyMatter from Microsoft Security Copilot
The differences that matter most when your SOC needs autonomous AI that investigates and responds across your full stack, not an AI assistant that still leaves the work to your analysts. Here's how GreyMatter compares.
No. Security Copilot is an AI assistant that layers on top of Microsoft's security stack. It provides summarizations, query suggestions, and remediation guidance, but your analysts still review, decide, and execute. GreyMatter is an agentic AI security operations platform that detects, investigates, and responds autonomously across your full stack.
GreyMatter's Agentic Teammates handle 100% of Tier 1/2 investigations autonomously at 99.4% accuracy, processing 74M alerts annually, then execute containment via ARPs. Security Copilot assists your analysts with suggestions and summarizations but does not complete investigations or execute response independently. Your team retains the manual investigation and response burden.
M365 E5 customers receive 400 SCUs/month per 1,000 licensed users, capped at 10,000 SCUs/month. Active SOC usage can consume that allotment quickly, with overage SCUs at $6/hour. Non-E5 customers pay $4/SCU/hour provisioned. GreyMatter is priced per endpoint with no consumption meters, so costs stay predictable regardless of AI usage volume.
GreyMatter's AI investigates across all 250+ integrated tools with consistent depth regardless of vendor. Security Copilot's investigation quality is tied to the Microsoft security data available. Non-Microsoft EDR, SIEM, identity, or cloud tools provide less context, producing shallower investigations and wider blind spots.
No. Every Security Copilot investigation starts from scratch. The AI does not carry forward your team's context, heuristics, or learned patterns from prior sessions. GreyMatter's Agentic Memory persistently stores customer-specific guidelines and investigation patterns, applying that context automatically to every future investigation.
GreyMatter's ARPs execute containment directly across 250+ integrated tools including non-Microsoft EDR, IAM, email, cloud, and network products. Security Copilot's containment is fragmented: your team must navigate to the embedded Copilot within each individual Microsoft product portal, and cross-stack containment outside Microsoft requires pivoting to each tool's native console.
GreyMatter is technology-agnostic with 250+ bidirectional integrations, preserving your flexibility to adopt best-of-breed tools from any vendor. Security Copilot's full value requires deep commitment to Sentinel, Defender XDR, Entra, Intune, and Purview. Investigation depth and response capability degrade outside the Microsoft ecosystem.
