Powerful Cloudflare protection

Additionally, with granular custom rules, you can configure your WAF to protect against any threat or implement business-specific security policies.

WAF layered defenses

  • Cloudflare managed rules offer advanced zero-day vulnerability protections.
  • Core OWASP rules block familiar “Top 10” attack techniques.
  • Custom rulesets deliver tailored protections to block any threat.
  • WAF Machine Learning complements WAF rulesets by detecting bypasses and attack variations of RCE, XSS and SQLi attacks.
  • Exposed credential checks monitor and block use of stolen/exposed credentials for account takeover
  • Sensitive data detection alerts on responses containing sensitive data.
  • Advanced rate limiting prevents abuse, DDoS, brute force attempts along with API-centric controls.
  • Flexible response options allow for blocking, logging, rate limiting or challenging.

There are billions of stolen credentials on the dark web to fuel credential stuffing that leads to account takeover.
