Detection Notes
Match `CCBot` as a case-insensitive substring in HTTP user-agent logs. Review bot_aliases for alternate names or product labels. Use bot_http_agent for full user-agent examples when the client sends a longer browser-like string. Do not treat a user-agent match alone as proof of identity for allow-listing.
