Overview
Petra Security provides an ITDR platform for Microsoft 365 environments, designed for MSSPs and organizations. It monitors Microsoft 365 components (Active Directory, Exchange, SharePoint, Teams) to detect threats like Business Email Compromise and token theft using data science and adaptive fingerprinting. It supports rapid onboarding with two-click integration, fast threat detection, and can lock out attackers without disrupting employees, plus detailed reporting and security assessments. Its goal is to help security teams investigate and shut down Microsoft 365 attacks quickly, strengthening protection across the Microsoft ecosystem.

What believers are saying
- CRN reported mid-seven-figure revenue and 1.5 million protected users by May 2026.
- AME Group caught 133 BEC attacks from August 2025 to January 2026.
- Petra serves 400+ channel partners, and partner-led expansion scales quickly across Microsoft tenants.
What critics are saying
- Microsoft Defender for Identity is bundled inside E5, crushing standalone pricing power in 2026.
- CrowdStrike, Silverfort, Huntress, and Sophos compete aggressively across identity detection and response.
- Petra remains tiny at $500K seed versus 122 competitors; one weak cycle kills momentum.
What makes Petra Security unique

- Petra claims 24/7 BEC hunting and attacker lockout without disrupting employee access.
- One-click tenant onboarding and partner billing integrations make channel deployment unusually fast.
