About Island

Island sells an enterprise browser that provides a managed environment for secure application access. The Enterprise Browser from Island installs locally on any device and is managed centrally through the cloud-based Island Management Console. Island's Enterprise Browser is based on the Chromium rendering engine, the same as Chrome and Edge. Island bears responsibility for hosting and maintaining the cloud services used in delivering the subscription service. Island natively supports RDP, Remote Desktop Protocol, and can serve as a client for web-streaming virtualized applications.[4]

Island supports Windows, MacOS, iOS, iPadOS, Android, Linux, ChromeOS and IGEL OS. Island is available as a browser extension for Chrome, Edge, Safari, Firefox and any Chromium-based browser. Island supports both a full Chromium-based browser and a browser extension, so users do not need to switch browsers to experience Island benefits.

Island automatically assesses device posture to ensure devices meet policy requirements. The Enterprise Browser defends against web-based threats, including built-in protection from malware, phishing attacks, session hijacking, man-in-the-browser and other browser exploits. Island creates context-based policies that allow data to move freely between enterprise apps while preventing data leakage. Island applies last-mile controls to print, downloads, screenshots and copy/paste, even outside the browser.

Island separates work and personal activity so that security policies apply only to work-related sites, while personal sites remain private. Island lets organizations see work activity in high fidelity, keeps personal browsing private, and shares analytics with a SIEM. Island's platform is designed for regulatory compliance with GDPR and HIPAA, offers audit logs, and does not sell or share customer data with third parties.

The Enterprise Browser provides organizations with secure access to any app or resource on any public or private network from inside the browser itself. Island Private Access is a ZTNA solution for both web and desktop apps. Island Private Access offers a second deployment option for the Island Enterprise Browser to support access to private web applications and semi-private SaaS applications. The Island Enterprise Browser integrates with existing Zero Trust Network Access (ZTNA) technologies. Island offers integrated ZTNA to securely connect to internal networks without the need for VPN. Island offers a SASE product with Perfect Packet architecture.[2][7][8]

Island can prevent copy/paste from sensitive applications, block downloads to personal devices, disable screenshots, apply watermarks and redact sensitive data on-screen. Island integrates with identity providers and application access controls to ensure corporate applications are only accessible through the authenticated Island browser. Contractors install a browser on any device, authenticate, and get access to the apps and resources they need, and nothing else. IT teams can configure Island to make applications available to users based on their role, location, or other criteria. Island can play a role in divestiture transactions, essentially running the onboarding playbook in reverse. Island adds an approval step for sensitive application actions. Island audits and logs all browser activity within a critical app session, including high-fidelity screenshots and click tracking. Island can insert approval steps and MFA challenges into any web application workflow without requiring API access, vendor cooperation, or application modifications.[7][9][10][11]

Island says AI agents are no longer limited to developers and every employee now has access to them. Island sits where AI is used: browser, endpoint, network, every tool call. Island uses one control plane that captures the full chain, from prompt to tool call to file, with one policy for humans and agents. Island lets employees use approved AI tools while keeping PII, IP and financial records out of prompts and outputs. Island lets any agent navigate legacy, no-API internal apps under full DLP, redaction and audit via Browser-use MCP. Island blocks adversarial prompts targeting agents and the data they touch, including indirect injection from web and document content. Island provides content-level audit records tied to user, device, agent and policy, exportable for SOC 2, ISO 27001 and internal review.[12]

Island includes productivity tools such as an AI Assistant for writing, researching and summarizing, a smart clipboard, an ad and tracker blocker, and a geolocation anonymizer. Users auto-generate, save and retrieve passwords with one click in Island, and passwords are encrypted and stored using a zero-knowledge architecture. Island DEX collects analytics on application usage, performance, network and device health.[1][3][13]
