Browser protection is a set of security controls that reduces risk while people browse websites and use web applications. Depending on the product, controls may block known malicious sites, restrict risky actions, isolate browsing sessions, or apply policies to web activity.
It matters because browsers are where users follow links, sign in to cloud services, and handle sensitive data. Attackers may exploit phishing pages or misuse an authenticated session, so browser controls can help limit exposure and provide visibility. They are one layer of defense, not a replacement for strong identity protections, secure devices, and monitoring for unusual account activity.
