CIDRAM

Open-source CIDR-based access manager for blocking malicious IP ranges.

Servicefreeglobal

An open-source access manager and firewall, CIDRAM uses CIDR-based signatures and blocklists to block traffic from known-malicious IP ranges. It helps web server administrators avoid the overhead of manually maintaining IP blocklists by applying automated CIDR rules and community-maintained lists to reduce unwanted or harmful traffic.
