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.

Get More From the Defender XDR You Already Own
Your Defender XDR becomes more valuable, because something finally acts on what it produces. Simbian reads it, acts back into it, and keeps what it learns for the next case.

What it keeps, so the next investigation goes better
- Which devices and mailboxes matter most

One entry covers the whole pattern, and every other alert in scope is still investigated in full.
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.
Reviewable Decision Trail
Every hunting query, verdict, and action on a Defender XDR incident is recorded with its rationale, so each decision is auditable end to end.
Use AI to Automate XDR Incidents
Defender XDR already correlates the incident. Simbian investigates it across endpoint, identity, email and cloud apps, and responds on average under 4 minutes from detection to response.

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.
