Based on the Nmap open source tool, Flan Scan was born out of the need for an easy-to-deploy scanner that could accurately detect the services on a network and then look them up in a database of CVEs to find any relevant vulnerabilities.

Cloudflare chose Nmap as the base scanner due to its focus on reducing false positives and because the Nmap Scripting Engine (NSE) allows scripts to be run against the scan results. Moreover, the “vulners” script on NSE would already map detected services to relevant CVEs from a database.

“[...] By complementing osquery’s findings with Flan Scan’s network scans we are working towards comprehensive visibility of the services running at our edge and their vulnerabilities,” Cloudflare says.
“Cloudflare’s mission is to help build a better Internet for everyone, not just Internet giants who can afford to buy expensive tools. We’re open sourcing Flan Scan because we believe it shouldn’t cost tons of money to have strong network security,” the security firm concludes.
