Microsoft Security Copilot assists your analysts.
Simbian's AI SOC Agent investigates every alert.
Microsoft calls Security Copilot the AI that assists, and adds agents for specific jobs across Defender, Entra, Intune, and Purview. Simbian's AI SOC Agent investigates and responds to every alert across your whole stack, on-prem or in the cloud, alongside an AI Pentest Agent that proves which attack paths are open.

Both put AI agents in your SOC. Simbian's Agents also prove the attack path and run on-prem.
Inside Microsoft's portals, Security Copilot's agents triage alerts and suggest fixes, and analysts prompt the assistant for everything else. On any stack, Simbian's AI SOC Agent takes each alert from first signal to response. Every pentest finding feeds what it learns.
What both do
- ●False positives closed without an analystEach verdict comes with its reasoning, and benign alerts get closed.
- ●Analyst feedback shapes the next verdictYour team's corrections carry over to similar alerts later.
- ●Approval before high-impact actionsDisabling a user or isolating a device needs a yes first. You choose what runs unattended.
- ●Built to work with Microsoft Sentinel and DefenderBoth read Defender alerts and the Sentinel data lake, so neither asks you to move your data.
Where Simbian pulls ahead
- ▸Every alert worked from signal to responseSimbian's AI SOC Agent investigates and responds with no prompt, promptbook, or playbook to write first.
- ▸Any SIEM or EDR, on-prem or air-gappedIt reads from 100+ tools, acts in 25+, and you pick the LLM.
- ▸An AI Pentest Agent that exploits and proves the pathIt works in your running environment and records the evidence.
- ▸One Context Lake™ that offense and defense both feedA proven attack path changes how the AI SOC Agent ranks an alert, and threat hunts start from what the SOC just flagged.
Security Copilot vs Simbian: two ways to run SOC agents
Microsoft builds an agent into each of its security products and gives analysts an assistant for the rest. Simbian's Agents work across the security tools you already run, Microsoft's included.

Core unit
Microsoft Security CopilotA generative AI assistant in the Defender, Entra, Intune, and Purview portals, plus Microsoft and partner agents that each handle one job, such as alert triage, threat intelligence briefings, or conditional access. A separate agentic system, Project Perception, is in invitation-only preview.
SimbianAI SOC, AI Pentest, and AI Threat Hunt Agents on one platform, sharing one Context Lake.
How work starts
Microsoft Security CopilotAn analyst prompts the assistant or runs a promptbook, a saved sequence of prompts. Agents run on their own triggers inside the product they belong to.
SimbianEvery alert is picked up and investigated to a verdict, and nobody has to write a playbook first.
Threat hunting
Microsoft Security CopilotThe Threat Hunting Assistant turns questions into KQL, and Microsoft's guidance is to ask one question at a time.
SimbianThe AI Threat Hunt Agent writes, runs, and interprets its own queries, tests several hypotheses in parallel against months of data, and returns a verdict.
Offense
Microsoft Security CopilotProject Perception's Recon Agent maps attack paths in Azure and, in Microsoft's words, doesn't exploit vulnerabilities or execute payloads.
SimbianThe AI Pentest Agent exploits the path in your live environment and records the evidence. Related alerts move up in severity.
Memory
Microsoft Security CopilotEach agent keeps the feedback your analysts give it and applies those lessons to its own future work.
SimbianOne Context Lake that the AI SOC, AI Threat Hunt, and AI Pentest Agents read from, holding your assets, identities, runbooks, and the decisions your team already made.
Data reach
Microsoft Security CopilotBuilt-in agents work on Defender, Sentinel, Entra, and Azure data. Other tools connect through plugins bought separately, or by ingesting their data into Sentinel.
SimbianReads from 100+ tools and acts in 25+, Microsoft Sentinel and Defender among them.
Deployment
Microsoft Security CopilotSaaS in Microsoft's commercial cloud, on Azure OpenAI models. Microsoft says it isn't designed for US government clouds such as GCC, GCC High, or DoD.

How does Simbian compare with Microsoft Security Copilot?
Security Copilot is ahead on saved prompt sequences inside Microsoft's portals, and neither product connects to every tool out of the box. Simbian is ahead on end-to-end alert work, a memory that offense and defense share, and deployment choice.

Frequently Asked Questions
Microsoft Security Copilot is Microsoft's generative AI assistant for security and IT teams, generally available since April 2024, when it launched as Microsoft Copilot for Security. Analysts ask it questions in natural language or run promptbooks, and it's built into Defender, Sentinel, Entra, Intune, and Purview. It runs as SaaS in Microsoft's commercial cloud on Azure OpenAI models, alongside agents that handle specific jobs.
Security Copilot agents each handle one job inside a Microsoft product. The triage agent closes false-positive alerts in Defender, the Conditional Access Optimization Agent suggests policy fixes in Entra, and the Vulnerability Remediation Agent prioritizes fixes in Intune. Partners add more through the Security Store. Simbian runs one AI SOC Agent that works alerts across your SIEM, EDR, identity, and cloud tools.
Partly. Security Copilot reaches tools such as Splunk and ServiceNow through plugins that are bought separately, and Microsoft's built-in agents work on data in Defender, Sentinel, Entra, and Azure, so other telemetry generally has to be ingested into Sentinel first. Simbian's AI SOC Agent reads from 100+ security and IT tools directly and acts back into 25+ of them.
No. Microsoft describes Security Copilot as a SaaS application and says it is not designed for US government clouds, including GCC, GCC High, and DoD, or for Microsoft's sovereign clouds. Simbian deploys as SaaS, dedicated SaaS, private cloud, on-premises, or air-gapped, with your choice of LLM, so the AI SOC Agent can run inside the environment you already control.
Not against your live environment, as far as we could find. Project Perception's Recon Agent, in invitation-only preview, maps attack paths in Azure but doesn't exploit vulnerabilities or run payloads, and other Microsoft tools scan source code or test generative AI apps. Simbian's AI Pentest Agent exploits the path and shows the evidence, and the AI SOC Agent ranks any alert on that path higher.
Simbian. Its AI SOC Agent works every alert through to a response without waiting for a prompt or a playbook, across 100+ tools that include Microsoft Sentinel and Defender, and it deploys on-prem or air-gapped. The AI Pentest Agent proves which attack paths are open, and because both Agents feed one Context Lake, the defense improves with each case.
