Every Defender alert, automatically resolved.
Simbian AI agents natively integrate with Microsoft Defender for Endpoint to automatically triage, investigate, and respond to endpoint threats. Around the clock, no playbooks, no SOC alert fatigue.
Trusted by leading enterprises and MSSPs
Automated Defender for Endpoint Alert Triage and Endpoint Response
Simbian agents use the full Microsoft Defender for Endpoint API surface — ingesting alerts, enriching with STIX threat intel, and executing response actions across your entire endpoint fleet.
Automated Alert Triage
Simbian continuously ingests Defender for Endpoint alerts and assigns verdicts using cross-domain context, eliminating manual triage queues.
Endpoint Isolation & Containment
Instantly isolate compromised machines through Defender's machine isolation API — cutting off lateral movement without waiting for analyst approval.
Deep Threat Investigation
Automatically query advanced hunting tables (DeviceProcessEvents, DeviceNetworkEvents) to reconstruct full attack chains from initial access to impact.
STIX-Enriched Detection
Correlate every alert with STIX-formatted threat intelligence indicators, adding context that accelerates verdict confidence.
Bi-Directional Response Actions
Read alerts, update incident status, restrict app execution, collect investigation packages, and run live response commands directly through Defender APIs.
Cross-Platform Correlation
Combine Defender endpoint telemetry with identity signals from Entra ID, email data from Defender for Office 365, and SIEM context for full-scope investigations.
Use AI to Automate Defender Alerts
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 detection to verdict in 30 seconds — every reasoning step auditable.
Four Steps to Automated Endpoint Security with Defender
From API connection to automated containment, Simbian handles your endpoint security lifecycle without playbooks or manual handoffs.
Connect
Simbian connects to Microsoft Defender for Endpoint via Microsoft Entra ID (Azure AD) app registration with OAuth2 delegated permissions. No agents to deploy, no infrastructure changes.
Monitor
AI agents continuously ingest Defender alerts, advanced hunting telemetry, and machine health signals — covering your entire endpoint fleet around the clock.
Investigate
For every alert, Simbian runs advanced hunting queries across DeviceProcessEvents and DeviceNetworkEvents, correlates with threat intelligence, and builds the full attack narrative automatically.
Respond
Execute machine isolation, stop-and-quarantine actions, restrict application execution, or collect forensic packages — all directly through the Defender for Endpoint API.
Real Threats. Automated Outcomes.

Isolate Ransomware Hosts in Under 2 Minutes
When Defender detects ransomware behavior patterns, Simbian immediately isolates the machine, maps lateral movement through advanced hunting, and blocks related indicators fleet-wide — before an analyst is paged.
Contain Fileless Attacks Before They Persist
Simbian detects in-memory threats flagged by Defender's behavioral sensors, traces the parent process chain, and restricts malicious application execution across affected endpoints — all within seconds of detection.
Stop Credential Harvesting at the Endpoint
LSASS access alerts from Defender trigger an automated investigation across endpoint and identity telemetry. Simbian correlates with Entra ID sign-in anomalies and contains the affected machine before credentials are exfiltrated.
