Island has a focus towards enterprise security utilizing built-in Data Loss Prevention, Phishing Protection, Zero Trust replacing SASE / VDI, whereas Google's Chrome has a focus on General Management. Island is premium priced compared to Chrome when it comes to consolidating security features versus Chrome being lower priced per user.
Island for organizations requiring high levels of Security and replaces Multiple Tools; Chrome for Organizations requiring Cost-Effective Basic Management.
Island utilizes a chromium-based security enclave and provides offline policy enforcement, whereas Microsoft's Edge uses the Microsoft Defender ecosystem however lacks Island's browser-native data control capabilities. Both target similar types of enterprises however Island is focused on Browser Isolation.
Island for browser-specific Threats; Edge for Organizations utilizing Microsoft-centric Stacks.
Island positions itself as a SASE Replacement using its $250 million dollars in funding, faster onboarding for contractors, and less IT Overhead compared to the complexity of VDI deployments. Momentum is building in the Enterprise Browser Category.
