What is behind the name halo? A halo is a glowing ring of light, often shown around something valuable or sacred - a symbol of protection, safety, and visibility. Halo represents a protective shield around every browser. It wraps enterprise-grade security around Chrome, Edge, Firefox, and Safari without changing how users work. It is a security layer that follows the browser everywhere, safeguarding SaaS, extensions, and data flows.  In short: Halo = a protective layer of security around the browsers people already use and trust.
