Every XDR incident, automatically resolved.
Simbian AI agents natively integrate with Microsoft Defender XDR to automatically triage, investigate, and resolve cross-domain incidents. Continuous coverage across endpoints, identity, email, and cloud — no playbooks required.
Trusted by leading enterprises and MSSPs
Automated Defender XDR Incident Triage and Response
Simbian agents consume the full Defender XDR incident graph — correlating alerts across domains and executing response actions without manual intervention.
Unified Incident Triage
Simbian ingests correlated Defender XDR incidents (not just individual alerts), preserving the cross-domain attack context Microsoft already assembled.
Cross-Domain Investigation
Automatically pivot across endpoint, identity, email, and cloud app signals within a single Defender XDR incident to map the full attack chain.
Advanced Hunting Queries
Run KQL queries across the unified Defender data lake to uncover related activity that the built-in correlation may have missed.
Multi-Surface Containment
Isolate endpoints, disable compromised accounts, block malicious emails, and revoke OAuth app consent — all from a single incident response.
STIX-Enriched Context
Enrich every incident with STIX-formatted threat intelligence indicators and Simbian's Context Lake for organization-specific insight.
Context Lake™ Enrichment
Every XDR incident is enriched with org-specific tribal knowledge, SOPs, past investigations, and analyst feedback along with security telemetry from across your environment.
Use AI to Automate XDR Incidents
Most SOC teams spend 80% of their time on alerts that turn out to be false positives. Simbian closes them in seconds.

A real-world investigation, end to end. From incident to verdict in 38 seconds — every reasoning step auditable.
Four Steps to Automated XDR Incident Response
From connection to cross-domain containment, Simbian handles your XDR incidents end to end without playbooks or analyst queues.
Connect
Simbian connects to Microsoft Defender XDR via Microsoft Graph Security API with OAuth2 app-only permissions. No agents, no infrastructure changes.
Monitor
AI agents continuously ingest Defender XDR incidents and their correlated alert evidence — spanning endpoint, identity, email, and cloud app detections.
Investigate
For every incident, Simbian traverses the full alert graph, runs advanced hunting queries, and correlates with external threat intelligence to build a unified attack narrative.
Respond
Execute containment across all surfaces — isolate devices, disable accounts, purge malicious emails, and update incident classification — directly through Microsoft APIs.
Real Threats. Automated Outcomes.
See how Simbian and Microsoft Defender XDR work together to resolve multi-domain attacks that would otherwise require hours of analyst coordination.
Contain Business Email Compromise in Minutes
Defender XDR correlates a phishing email with a compromised identity and suspicious mailbox rules. Simbian automatically disables the account, purges forwarded messages, and revokes active sessions — before data exfiltration completes.
Resolve Multi-Stage Intrusions Across Domains
When Defender XDR links an endpoint detection to lateral movement via compromised credentials, Simbian investigates all correlated alerts simultaneously, contains affected assets across surfaces, and delivers a complete timeline to your team.
Stop Malicious OAuth App Consent Grants
Defender XDR flags suspicious OAuth consent. Simbian correlates with sign-in anomalies, maps data access scope, revokes the app grant, and disables the granting account — automatically closing the attack path.
