    PeerGuardian

    PeerGuardian - a privacy oriented firewall application

    PeerGuardian is a privacy oriented firewall application. It blocks connections to and from hosts specified in huge blocklists (thousands or millions of IP ranges). Its origin seeds in targeting aggressive IPs while you use P2P. PeerGuardian Linux: Not developed actively anymore. Team might still be around. Some unreleased changes on git. Outdated technology. Peerguardian OS X: Not developed anymore. We've lost contact with the OS X developer. PeerGuardian Windows: Not developed anymore. It's highly recommended to use PeerBlock instead, which is a continuation of PeerGuardian's development in Windows, with bug fixes and support for Windows Vista and Windows 7. Collaboration with peerblock.com is welcome! PeerGuardian is an open project. Not only is its source code open for you to read, use, and modify - but the project is open for you to join and contribute in any form (code, documentation, bug reports, web and support).

    CrowdSec

    CrowdSec

    Firewall able to analyze visitor behavior & provide adapted response

    CrowdSec - an open-source massively multiplayer firewall able to analyze visitor behavior & provide an adapted response to all kinds of attacks. It also leverages the crowd power to generate a global IP reputation database to protect the user network. Crowdsec shouldn't, and didn't crash any production so far we know, but some features might be missing or undergo evolutions. IP Blocklists are limited to very-safe-to-ban IPs only (~5% of the global database so far, will grow soon). A modern behavior detection system, written in Go. It stacks on Fail2ban's philosophy, but uses Grok patterns & YAML grammar to analyse logs, a modern decoupled approach (detect here, remedy there) for Cloud/Containers/VM based infrastructures. Once detected you can remedy threats with various bouncers (block, 403, Captchas, etc.) and blocked IPs are shared among all users to further improve their security. Crowdsec is an open-source, lightweight software, detecting peers with aggressive behaviors.

    FireHOL

    FireHOL

    A firewall for humans.

    FireHOL is a language (and a program to run it) that builds secure, stateful firewalls from easy-to-understand, human-readable configurations. The configurations stay readable even for very complex setups. FireQOS is a program that sets up traffic shaping from an easy-to-understand and flexible configuration file. Both programs abstract away the differences between IPv4 and IPv6. so you can concentrate on the rules you want. You can apply rules for IPv4 or IPv6, or both, as you need.
