Your Microsoft 365 Tenant
Is Under Attack?
Don't panic. O365Validator IR helps you detect what's compromised, understand what happened, and evict attackers from your environment - all in one platform.
What We Detect During an Investigation
Our IR engine analyzes multiple data sources to identify indicators of compromise and attacker persistence mechanisms in your Microsoft 365 tenant.
Malicious OAuth Applications
Detect known bad OAuth apps from our database of 500+ compromised applications, plus anomaly detection for suspicious permission patterns.
Suspicious Inbox Rules
Identify inbox rules attackers create to hide their activity, forward sensitive emails, or intercept communications.
Compromised Accounts
Analyze sign-in logs for impossible travel, suspicious IPs, and authentication anomalies indicating account takeover.
Admin Configuration Changes
Review audit logs for unauthorized changes to security settings, conditional access policies, and admin role assignments.
Federation & Trust Abuse
Detect Golden SAML attacks, unauthorized federation trusts, and service principal credential additions.
Data Exfiltration Indicators
Identify unusual file access patterns, bulk downloads, and suspicious sharing activity across SharePoint and OneDrive.
Evict Attackers with Confidence
Take immediate action to remove attacker access. Every destructive action includes rollback capability in case of false positives.
Revoke User Sessions
Immediately terminate all active sessions for compromised accounts, forcing re-authentication.
Disable OAuth Apps
Remove consent grants and disable malicious applications with a single click.
Reset Passwords
Force password reset for affected accounts with secure temporary credentials.
Remove Inbox Rules
Delete malicious inbox rules that attackers use to hide their presence.
Block Sign-In
Temporarily disable compromised accounts to prevent further access.
Revoke Refresh Tokens
Invalidate all refresh tokens to break persistent attacker access.
All actions are logged for audit trails and compliance documentation
