Almost 100% of the time a CloudFlare customer site will be free of Malware. A primary objective for Scan was to help customers understand how recently their domain had been scanned for malware, so that they can be confident in their site security.
We also wanted to highlight to customers that if their site requires additional security, they can upgrade their Cloudflare plan to receive more frequent Scans, as well as Cloudflare’s Advanced Scan. Advance Scan improves your security by utilizing a CloudFlare crawler that will search every URL on your website and check it against our sources to see if the link is blacklisted anywhere else.
Because Cloudflare also leverages Google and Facebook scans, we wanted to be transparent about which service had detected a threat. We also wanted to provide users with the exact URL location of where the threat was detected, to help them remove it.
Lastly, because Scan consumes bandwidth, we wanted to provide users with the option to turn scan on and off.
