The customer would like to have more detailed information about Broadcom Cloud SWG (formerly known as WSS) Antivirus / Anti-malware systems and capabilities.
Cloud SWG uses Symantec antivirus and anti-malware engines (also known as Stargate).
The Stargate release notes can be found here.
We are also using ClamAV antivirus scan engine in dual mode (by default both Symantec and ClamAV engines are used).
