Gartner defines a secure enterprise browser (SEB) as a solution that delivers enterprise security policies and controls through a centrally managed browser extension, and optionally, a full-stack custom web browser. SEBs provide security and policy enforcement for web, SaaS and private applications, as well as browser hardening delivered through the browser rather than at the endpoint OS or network level. SEBs also enable visibility, control, and auditability of web application data accessed by end users from managed, lightly managed or unmanaged devices without the need for in-line decryption of web traffic.
