About
Island is a Dallas, Texas-based cybersecurity company that developed the Enterprise Browser — a Chromium-based web browser purpose-built for enterprise security, compliance, and IT governance. Founded to address the reality that nearly all enterprise work now happens in the browser, Island''s platform provides security and control at the browser layer: including data loss prevention (DLP), web filtering, session recording for compliance, application access control, and identity integration — without requiring VPNs, SASE solutions, or endpoint agents for many use cases.
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.
