Identity protection, reinvented for the modern threat landscape.
Secure every system from identity compromise.
Our mission statement is intentionally simple. Because identity is not.
Most security companies solve pieces of the identity problem—MFA here, privileged access there, SSO somewhere else. But identity threats don't exist in isolation. They exploit the gaps between your tools, the interactions between users and services, the toxic combinations of permissions that no single system can see. That's why Hummingbird Security built the Auth Sentry platform.
Identity is complex and requires context. A login from a new location isn't suspicious on its own. But combined with impossible travel patterns, recent permission escalations, and access to sensitive resources? That's an attack in progress.
You can't solve identity security piecemeal. You have to see the whole picture—human identities, service accounts, AI agents, permissions, behaviors, and risks—and protect them as an interconnected system. The Auth Sentry platform does exactly that, providing the holistic visibility and automated response needed to secure every system from identity compromise.
We see identity threats as a system-wide problem, not isolated incidents
Understanding relationships between identities, permissions, and behaviors
Every identity type, every system, every attack vector—all protected
Hummingbird Security was founded by Art Sturdevant, a cybersecurity leader with 15+ years of experience building and scaling security operations. As a former Sr. Security Engineer at Duo Security and VP of Technical Operations at Censys, our founder saw firsthand how traditional tools were failing to protect against modern identity threats.
At Duo Security, we witnessed the evolution of authentication attacks—from simple credential stuffing to sophisticated MFA fatigue campaigns. At Censys, our team provided visibility into internet-facing assets for Fortune 500 companies. These experiences revealed a critical gap: organizations had visibility into their external attack surface but were blind to identity-based threats happening inside their walls.
MFA fatigue attacks, impossible travel patterns, and toxic permission combinations were slipping through the cracks—costing organizations millions in breaches. We built the Auth Sentry platform to solve this problem. Not another dashboard that just alerts, but an active defense system that detects, analyzes, and contains identity threats in real-time.
Based in Ann Arbor, Michigan, we're a team of security engineers, data scientists, and product builders united by one goal: making identity protection fast, effective, and accessible to every organization.
Deploy in minutes. Detect in seconds. Contain immediately. We respect your time.
Vetted alerts with the context security analysts need to make fast, confident decisions.
Your success is our success. We're in this together.
We challenge convention and rethink security from first principles.
We eat our own dog food. Our platform meets the highest security standards.
Clear communication, honest feedback, and no hidden surprises.
We're proud to build world-class security technology from the heart of the Midwest. Our location gives us access to top-tier talent from University of Michigan while maintaining the focus and efficiency that comes from avoiding the noise of traditional tech hubs.
