Island Enterprise Browser vs SURF Zero Trust Enterprise Browser

Island Enterprise Browser is a business browser with security, visibility, and management features built in. Administrators can set conditional access policies based on identity, device, network, location, and application context. Context-based policies and last-mile controls govern printing, downloads, screenshots, and copy and paste to help prevent data leakage. Island says the browser protects against malware, phishing, session hijacking, man-in-the-browser attacks, and other browser exploits. Built-in tools include an AI assistant, smart clipboard, ad and tracker blocker, geolocation anonymizer, and password manager. It separates work and personal browsing and displays indicators when activity is monitored. Island also describes automation and customization for SaaS and web applications without changing their source code or relying on proprietary APIs. The browser integrates with identity providers such as Azure AD and Okta and can work with zero trust network access and endpoint protection platforms. Listed coverage includes Windows, macOS, Linux, Chromebook, iOS, iPadOS, and Android, plus extensions for Chrome, Edge, Safari, and Firefox. Extension support has some parity limits. Pricing is on request; the listed plan costs $250,000 a year on a 12-month contract.

SURF Zero Trust Enterprise Browser is a browser and extension for organisations that enforce security controls on user devices. It can discover AI tools, mask sensitive prompts, and block risky uploads in real time. A sandboxed, human-verified runtime is described for autonomous browser agents, with an air gap between planning and live access. Scoped access to corporate applications is available for contractors, BYOD staff, and acquired teams without VPN or VDI. SURF says it logs AI interactions and policy decisions while keeping personal browsing private. Controls map to GDPR, ISO 27001, SOC 2, and DORA, with SOC 2-ready evidence generation. Deployment can use existing MDM or self-installation, and enforcement runs on the device without proxy or cloud redirection. The full browser supports Windows, macOS, and Linux; mobile support includes iOS, iPadOS, and Android. The extension works with Chrome, Edge, and other Chromium browsers. Integrations include Okta, Microsoft, Splunk, Datadog, Kandji, HashiCorp, VirusTotal, and Elastic.
