Is Your Network Under Attack?
Are You looking For Immediate Protection?

​

You are in the right place,

Cloudflare and Synopsis are here to help you.

Introducing "I'm Under Attack Mode." The name is pretty self-explanatory: it's a new security level you can set for your site when you're under attack. The effect is that we will add an additional set of protections to stop potentially malicious HTTP traffic from being passed to your server.  While we perform a number of additional checks, the only thing noticeable to legitimate visitors to your site is that when they first arrive they'll see an interstitial page for about 5 seconds while checks are complete. Think of it as a challenge where the tests are automatic and visitors never need to fill in a CAPTCHA.

After verified as legitimate by the automated tests, visitors are able to browse your site unencumbered and won't typically see the test page again. Javascript and cookies are required for the tests and recording the fact that the tests were correctly passed. We've also designed the new checks to not block search engine crawlers, your existing allowlists, and other pre-vetted traffic. As a result, enabling I'm Under Attack Mode will not negatively impact your SEO or known legitimate visitors. What's also cool is that data on attack traffic that doesn't pass the automatic checks is fed back into CloudFlare's system to further enhance our traditional protections.
