Last month we released a beta of Internet Gatekeeper for Linux. Now it has reached maturity and we’re announcing its general availability. Internet Gatekeeper is a stable multi-purpose virus scanning proxy that supports the FTP, SMTP, POP3 and HTTP protocols. As mentioned before, the Internet Gatekeeper now builds upon the same foundation as our product Linux Security, enabling us to provide fast and effective updates. IGK supports several modes of operation, including acting as a transparent proxy, a reverse proxy scanning incoming files in HTTP PUT or POST request, as well as chaining with other proxy software such as Squid.
