Application security: The AppSec Component turns the Security Engine into a web application firewall and can protect web applications from the latest vulnerabilities.

Commercial usage: The pricing FAQ says commercial use of CrowdSec data in an offering is available through its Partnership Program, with partner pricing on request.
