GFI DownloadSecurity for ISA Server enables you to assert control over what files your users download from HTTP & FTP sites. Downloaded files are content checked for viruses, malicious content and objectionable material, and can be quarantined based on file type and which user downloaded them. GFI DownloadSecurity handles the security risk of file downloads without resorting to blocking all file downloads at firewall level! Blocking of file downloads is an unpopular policy, and results in your having to temporarily open ports/file types for users, resulting in additional administration and potential security holes.
