Most of the market WAF are already supported it.

• Cloudflare WAF supports expressive rate limiting based on HTTP methods, traffic patterns, and custom error status codes, allowing you to block IPs that generate too many 401/403/500 errors. Rules can act upon request rates and error ratios, with blocks escalated via Cloudflare's automation tools.​

• Fastly Next-Gen WAF enables condition-based thresholds, so you can block IPs with a high error rate under a configurable window, and escalate actions for repeated violations.​

• Azure Front Door can implement custom rules that block IPs exceeding request and error quotas, with adaptive durations for repeat offenders
