Circle Security

About Circle Security

In the AI era, passwords and traditional MFA are no longer enough. The problem was never authentication strength, it is the existence of credentials. Credentials can be stolen, phished, replayed, or generated at scale. As AI accelerates impersonation and automation, any system built on shared or transferable secrets becomes a liability. Circle Security builds the human identity layer for AI — authentication that proves a real person is present, every time, without relying on credentials. Our core product, Circle Access, eliminates passwords and transferable credentials at the protocol level. Identity is cryptographically bound to a verified human through biometric hardware. Nothing to steal, nothing to phish, nothing to replay. Authentication happens in seconds via a QR-based flow, and integrates beneath existing identity platforms like Okta, Microsoft Entra ID, and Ping Identity without disrupting your existing stack. For organizations that need visibility beyond the login event, Circle Elite extends protection to the broader human attack surface. It reduces exposure of sensitive personal and professional identity data in real time. SOC 2 Type I certified. Aligned with Zero Trust architecture, NIST 800-207, and CMMC frameworks. Built for organizations that cannot afford to trust credentials.
