Reverse proxy is used to protect web servers by providing additional layer of defense by hiding the web server behind the proxy. While in Reverse Proxy mode, can IWSVA scan HTTPS traffic?
While in reverse proxy mode, IWSVA cannot scan files through HTTPS. It can only scan malware through HTTP and FTP.
You need to install an Anti-virus (AV) software on the web server to scan the files that are being dropped into the server's file system.
