Talon Cyber Security · talon-sec.com · Same category (enterprise browser), same buyer (CISO), same workflow (secure browsing for managed and unmanaged devices). Talon was acquired by Palo Alto Networks in 2024, validating the category but also creating a competitor with distribution scale.[7]

LayerX Security · layerxsecurity.com · Overlapping buyer (CISO) and workflow (browser-native security controls), but LayerX is a browser extension rather than a full browser, making it lighter-weight but less deeply integrated.[7]

Zscaler · zscaler.com · Overlapping budget (network security / SASE) and workflow (secure web access, zero-trust). Island positions its Enterprise Network as a SASE replacement. Zscaler is public, $2B+ revenue, and the incumbent being displaced.[5][7]
