Virus Blocker

Don’t wait until viruses infect your devices—block them at the gateway. Modern malware threats target servers, appliances, laptops, tablets, and even mobile phones. While it is important that all of these devices have end-point protection—with the latest versions of software and virus signatures—you may struggle with control over these devices as they connect offsite to unsecured networks, then return to your network with malware onboard. You need a first line of defense.

Virus Blocker leverages signatures from Bitdefender™, the leader in speed and efficacy, whose threat lab experts work 24-hours a day, 365-days a year to identify emerging threats. Heuristic models provide an additional layer of protection against zero-day threats, and real-time updates with no system downtime ensure that your network is always protected. Virus Blocker identifies and blocks zero-day threats, viruses, worms, Trojan horses, botnets, unknown malware, and new infections.
