How does OWASP ModSecurity Core Rule Set (CRS) relate to F5 AWAF?

Hi MSZall​ 
F5 uses its own proprietary engine and custom-built security rules instead of the OWASP ModSecurity Core Rule Set (CRS). Since F5 is a leader in the WAF space, its solution is generally more advanced and effective than ModSecurity with CRS, especially for enterprise use cases.
