Cisco Cisco Web Security Appliance S360

The following notes were restored to the AsyncOS 9.0.1 User Guide:

The SOCKS protocol only supports direct forward connections.

The SOCKS proxy does not support (will not forward to) upstream proxies.

The SOCKS proxy does not support scanning services, which are used by Application Visibility and 
Control (AVC), Data Loss Prevention (DLP), and malware detection.

The SOCKS proxy does not support policy tracing.

The SOCKS proxy does not decrypt SSL traffic; it tunnels from client to server.

Using a proxy is not supported for communications between the Web Security appliance and the file 
analysis service in the cloud, even if an upstream proxy is transparent to the Web Security appliance and 
communications with the File Reputation service use a proxy. 

The criteria for evaluating a file’s reputation and for sending files for analysis may change at any time. 
Criteria are available only to registered Cisco customers. See File Criteria for Advanced Malware 
Protection Services for Cisco Content Security Products, available from
