    "excerpt": "The enterprise browser market is consolidating fast. Palo Alto Networks acquired Talon Cyber Security for $458.6 million in late 2023 to fold into its Prisma SASE service, and this year both CrowdStrike (Seraphic Security) and Akamai (LayerX Security, for roughly $205 million) snapped up rivals. While competitors get absorbed into bigger security platforms, Island is doing the opposite - growing bigger on its own. Founded in 2020 and out of stealth since 2022, the Dallas-based company created the “Enterprise Browser” category by embedding security, access control, and productivity tools directly into the browser employees already use. It has since expanded into a consumer browser extension, endpoints, next-generation SASE architecture, and data protection, and now positions itself as an “agentic control plane” governing both people and AI agents. The pitch: one policy engine and one audit trail across five layers - last-mile control, network, data, identity, and observability - showing in real time who or what is acting, what it can reach, and whether that action should be allowed. Eight of the world’s ten largest banks now use Island’s Enterprise Browser, and headcount has doubled to 1,000 from over 500 a year ago. CTech reported Island’s revenue reached roughly $200 million by September 2026, growing near 100% annually. Island was co-founded in 2020 by Mike Fey and Dan Amiga...",
