Gateway Antivirus for Web traffic
CacheGuard Web Gateway antivirus scans the Web traffic at the gateway and instantly eradicates suspicious objects before they can enter into your network, while traditional antiviruses are installed locally on computers. But as soon as a malware reaches a network it is sometimes too late and it can harm. That’s why it represents a powerful and complementary security solution to traditional antiviruses.

CacheGuard antivirus is a complementary technology to traditional antiviruses installed on computers reinforcing your protection against malware threats coming from the Web.
