Integration with a proxy server over ICAP with feedback allows you to prevent malicious objects from entering the corporate LAN and prevent users of the host from visiting malicious or phishing websites. Kaspersky Anti Targeted Attack Platform acts as an ICAP server, and your proxy server acts as an ICAP client. The proxy server sends ICAP requests to the ICAP server. The ICAP server runs a scan and returns the result to the proxy server. If any threats are detected, a notification HTML page is displayed to the user on the host.
