CC and bot traffic: distinguish demand from resource abuse
Combine endpoint cost, session behavior and successful operations to reduce false positives.

Volume is only one signal
Campaigns, crawlers and client releases can all increase requests. Equal QPS does not imply equal cost for cached images and complex searches. Build endpoint baselines using latency, database load, caching and business success.
Correlate request behavior
Look for repeated costly queries, missing normal navigation, failed sign-ins and retry bursts. No single IP, user agent or TLS fingerprint proves maliciousness. Distinguish monitoring, callbacks and scheduled integrations from abusive automation.
Apply controls by workflow
Assess static assets, sign-in, search and payment callbacks separately. Review samples before enforcing limits or challenges; non-browser clients may not support interactive checks. Keep exceptions narrow and retain application signature verification.
Measure service outcomes
Measure reduced resource consumption alongside successful orders, logins and client-specific errors. Define rollback conditions and feedback channels. A higher block count is not itself evidence of a better outcome.
