InstaSafe Secure Enterprise Browser vs Island Enterprise Browser

InstaSafe Secure Enterprise Browser is a hardened Chromium browser for applying access and browser-action policies by user and application. Its controls cover clipboard use, uploads and downloads, printing, watermarking, and screenshot or recording prevention on platforms that expose those controls. URL rules are checked before requests leave the device; the browser also blocks known malicious destinations, forced redirects, and pop-under abuse. For governed applications, it enforces certificate policy and refuses downgraded or mis-issued connections. MFA, device-posture checks, and sessions through InstaSafe's gateway are included, with allowed actions and refusals logged by user, device, application, and action. Extension policies can allow-list browser add-ons. InstaSafe lists more than 800 SAML, OAuth, and OIDC applications, including Microsoft Entra ID, Google Workspace, Okta, Salesforce, SAP, AWS, and Splunk. It describes on-premise and air-gapped deployments with controllers and gateways inside the customer's boundary. Pricing is on request; listed startup plans are billed annually for under 50 user licenses, with sales contact required for more.

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.
