Rate Limiting
Advanced traffic throttling
Rate Limiting controls the number of requests to applications, protecting against overload, brute force, and abuse. The system offers granular policies based on combinations of IP, HTTP headers, cookies, geographic location, and custom expressions. A sliding window algorithm ensures precise enforcement of limits without loopholes related to burst allowance. Integration with Bot Management allows different limits to be applied to humans and bots, protecting against credential stuffing while maintaining a good UX.
