Zero-hour virus defenses offer protection during the first few hours after new viruses begin to spread, before traditional anti-virus signatures have been updated. Over the last few months, it’s become clear that zero-hour defense is a must have feature, with at least half a dozen companies making announcements about zero-hour products.
This week, Proofpoint shipped its Messaging Security Gateway 4.0 appliance, which includes the company’s new zero-hour anti-virus module. The company says its system “identifies new virus activity and takes preventive action an average of 10 hours before signature-based solutions even begin to respond.”
Traditional AV vendors might differ that characterization of their response times, but zero hour products are clearly the flavor of the month:
Another month or two like this, and “zero-hour” will simply be assumed, and thus cease to be a meaningful differentiator.
