An Emphasis on Accuracy

In head-to-head tests, our AI was found to be more accurate compared to other content filters out there. We not only find threats early, we’re right about discovering them. Our current accuracy rate is around 96%. 

In head-to-head comparisons, we found that our competitor only blocked 54% of the threats that we found. And when we looked at a list of threats found by our competitor, only 15% of them were actually threats.

Finding Threats Sooner

Webshrinker finds new threats as early as 59 hours ahead of competitor threat feeds. This is because of Webshrinker’s ability to scan a page, looking for individual threat markers, and determining if a site is likely to be a threat or not. We use imagery-based anti-phishing and regularly train our AI on up-and-coming threats.
