Cloudflare has introduced a new capability that enables administrators to integrate its Browser Isolation solution into their existing network from any traffic source such as IPsec and GRE via its WAN-as-a-service, Magic WAN. This feature allows companies to protect internet activity from browser-borne malware and zero-day threats without installing any endpoint software or requiring users to update their browsers. The integration of Browser Isolation with Magic WAN enhances network perimeter architecture and a defense-in-depth security strategy by eliminating the complexity, fragility, and performance limitations of legacy network perimeters.
