About
Callsign is a digital identity and authentication company founded in 2010 and headquartered in London, United Kingdom. The company builds an intelligent authentication platform that verifies user identity through multiple simultaneous signals — behavioral biometrics (how a user types, swipes, and moves a device), device intelligence (device fingerprinting, SIM state, GPS data), and contextual risk signals — in addition to traditional multi-factor authentication methods. By combining these layers into a single authentication decision, Callsign claims to achieve recognition accuracy of up to 99.999%, enabling frictionless authentication for legitimate users while flagging anomalous sessions for step-up verification or fraud review.
Delinea is a privileged access management platform delivering secrets management, privilege elevation, and session controls across cloud, on-premise, and hybrid environments.
About
Delinea is a privileged access management (PAM) company headquartered in Redwood City, California, formed in 2021 through the merger of Thycotic and Centrify — two established PAM vendors whose combination created one of the largest independent players in the privileged access security market. The merger was backed by TPG Capital and brought together Thycotic's Secret Server vault and cloud PAM capabilities with Centrify's identity-centric privileged access controls and zero trust architecture, creating a unified platform that addresses the full spectrum of PAM use cases: vaulting and rotating privileged credentials, enforcing just-in-time privilege elevation, recording and auditing privileged sessions, and managing machine and application secrets at scale.
