Cloudflare has introduced a new Browser Isolation service to protect against phishing attacks and credential theft within web browsers. Administrators can define Zero Trust policies, such as prohibiting keyboard input and file uploads during high-risk browsing activities. The service is integrated natively into Cloudflare's Secure Web Gateway and Zero Trust Network Access services, allowing users to browse more of the internet without taking on risks. This solution helps administrators balance security needs with employee productivity by providing control over user interactions with risky websites.
