Island

Island builds a full Chromium-based enterprise browser — not a bolt-on extension — that embeds session-level governance, data-loss protection, and network access controls directly where employees actually work, aiming to replace or consolidate pieces of VDI, SASE, and DLP point tools. As AI agents increasingly operate inside the browser alongside employees, Island has extended its positioning toward what it calls an “enterprise agentic control plane”.

Founded in 2020 and headquartered in Dallas, Texas with R&D in Tel Aviv, Island raised a $250 million Series E in March 2025 led by Coatue Management at a reported $4.8 billion valuation, bringing total funding to roughly $730 million. The company says a majority of the Fortune 50 are customers, including major banks, airlines, and healthcare organizations. Independently, Island holds a 2026 Gartner Peer Insights Customers’ Choice designation for Secure Enterprise Browsers, based on 331 verified reviews averaging 5.0 out of 5.0, with 98% of reviewers saying they’d recommend it — an unusually strong independent evidence base for a security product. A published case study describes a Fortune 100 financial-services firm that replaced legacy VDI with Island and reported a 40% reduction in security incidents.

Owning the entire browser layer, rather than layering controls on top of a standard browser, gives Island a genuinely different level of control over SaaS access, data movement, and now in-browser AI agent activity. Combined with the scale of its funding and the independently verified customer satisfaction data, this is one of the stronger evidence profiles in this batch, even as the enterprise browser category itself has drawn several credible competitors and a wave of 2026 acquisitions by larger platforms.
