Cisco CWS eliminates the need to backhaul traffic through headquarters for remote workers whereas Cisco WSA does not. Cisco CWS is a cloud-based web security service that provides comprehensive protection against web-based threats for users anywhere, on any device1. Cisco WSA is an on-premises web security appliance that provides web filtering, malware scanning, data loss prevention, and other features for users within the network perimeter2. One of the benefits of using Cisco CWS over Cisco WSA is that it eliminates the need to backhaul traffic through headquarters for remote workers, which can reduce bandwidth costs, latency, and complexity3. Remote workers can connect directly to the nearest Cisco CWS data center and receive the same level of web security as if they were in the office. Cisco WSA, on the other hand, requires remote workers to use a VPN or proxy to route their web traffic through the headquarters, which can affect their performance and user experience. References:
