Vanguard benefits form dual virus protection. Traditional methods of signature files and definition updates are provided alongside Zero Hour Technology to ensure there is absolutely no period of time when you are not protected against new threats.

Zero Hour Technology bridges the gap between virus outbreaks and definition files being made available by traditional Anti Virus systems. This gap can very often be more than 24 hours.

Integrated, multi-threaded virus signature scanning of all incoming and outgoing emails (bi-directional) including content, headers and attachments.

Automatically and securely updated every 15 minutes with no need to restart services using Gordano's patented update technology.

It is based on technology from Commtouch and Authentium.
