Island Enterprise Browser vs Spirex Secure 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.

Spirex Secure Enterprise Browser is a Chromium fork for enterprise use on web and Windows. It combines policy controls, data-loss prevention, DNS threat filtering, and zero-trust network access. Identity-aware, per-application access can be enforced without endpoint agents, VPNs, or proxies. Page sensors inspect redirects, suspicious overlays and iframes, hidden fields, risky active content, and browser-side injection patterns. The browser also detects brand-domain mismatches, deceptive sign-in prompts, and credential capture on other domains. Controls include screenshot protection, download blocking, and risk-triggered watermarks for sensitive uploads. Policies consider identity, application, source and destination context, and live page risk. A connector brokers approved private-application access from a datacenter or cloud VPC without inbound ports. Okta, Entra ID, and Google Workspace are listed integrations. Trials require application review for teams of 50 or more.
