A Windows User-Agent arriving on a Linux SYN, an MSS that tells the link, or a TLS RTT well above the TCP one are strong bot and proxy signals; combine them with JA3/JA4 TLS fingerprints for layered bot mitigation. The module only reports: scoring, logging or challenging is up to the configuration. Linux only (TCP_SAVE_SYN); variables are empty on HTTP/3.
