Advanced Rate Limiting
Defend your applications and APIs against abuse by throttling traffic that exceeds defined limits
Rate Limiting protects against denial-of-service attacks, brute force login attempts, traffic surges, and other types of abuse targeting APIs and applications.
BENEFITS OF RATE LIMITING
Mitigate DDoS attacks
Stop high-precision layer 7 attacks with granular configuration options.
Ensure API availability
Identify abusive traffic with high accuracy by rate limiting traffic based on any parameter of a request.
Protect customer data
Defend against brute force login attacks seeking to take over accounts and steal sensitive information.
Rely on transparent pricing
Avoid unpredictable costs associated with traffic spikes and enumeration attacks. We will not charge you for usage when you are under volumetric attack.
Pick the right option for you
Choose IP-based Rate Limiting to protect unauthenticated endpoints, limit the number of requests from specific IP addresses, and handle abuse from repeat offenders.
Upgrade to Advanced Rate Limiting if you want to protect your APIs from abuse, mitigate volumetric attacks from authenticated API sessions, and take full control of the parameters you rate limit on.

Gartner® named Cloudflare a Representative Vendor in Web Application and API Protection
Cloudflare has been recognized as a Representative Vendor in the Gartner Market Guide for WAAP report. We believe this recognition validates that we protect against emerging threats faster, offer tighter integration of security capabilities, and deliver powerful ease of use and deployment.
What our customers are saying
“When other companies experienced a data leak, the attackers would often try the stolen email and password combinations on our sites. We always knew when there was another attack, but it was business as usual because Cloudflare detected and stopped it before it became a problem.”
