Bot detection engines
Heuristics
The Heuristics engine processes all requests. Cloudflare conducts a number of heuristic checks to identify automated traffic, and requests are matched against a growing database of malicious fingerprints. JavaScript detections
The JavaScript Detections (JSD) engine identifies headless browsers and other malicious fingerprints. This engine performs a lightweight, invisible JavaScript injection on the client side of any request while honoring our strict privacy standards. We do not collect any personally identifiable information during the process. The JSD engine either blocks, challenges, or passes requests to other engines.JSD is completely optional. To adjust your settings, configure Super Bot Fight Mode from Security > Bots.
Notes on detection
Cloudflare uses the __cf_bm cookie to smooth out the bot score and reduce false positives for actual user sessions.
The Bot Management cookie measures a single user’s request pattern and applies it to the machine learning data to generate a reliable bot score for all of that user’s requests.
For more details, refer to Cloudflare Cookies.
Considerations
Bot Fight Mode and Super Bot Fight Mode use the same underlying technology that powers our Bot Management product. Specifically, these products:
- Protect entire domains without endpoint restrictions
- Cannot be customized, adjusted, or reconfigured via WAF custom rules
Although these products are designed to fight malicious actors on the Internet, they may challenge API or mobile app traffic. For more granular control, upgrade to Bot Management for Enterprise.
