Cisco Cloud Web Security or CWS as its known is a cloud based security offering from Cisco. CWS provides comprehensive defense, advanced threat protection and superior flexibility for organizations small and large. To enforce security, Internet traffic is redirected from the branch office location using either an existing Cisco infrastructure, such as the venerable Cisco ASA or multifunctional ISR series router. Alternatively, a host side proxy or agent software can also be deployed. CWS can even be bundled with the widely popular Cisco AnyConnect VPN software, making the “cloud attach” security deployment simple and flexible.
