IPFire vs Suricata

IPFire is a free, open-source firewall and security platform for networks from home offices to global enterprises. Its Linux Netfilter-based firewall supports network zones, port forwarding, NAT, and stateful packet inspection. VPN options include IPsec, WireGuard, and OpenVPN for site-to-site or remote access. A Suricata-powered intrusion prevention system detects and blocks malicious traffic using updated rule sets. IPFire includes a Squid web proxy with optional URL filtering through URLFilter or SquidGuard, and uses Red, Green, Blue, and Orange zones for roles such as trusted networks, DMZs, and Wi-Fi. Its web interface monitors bandwidth, connections, and intrusion attempts. Proxy authentication can use Microsoft Windows Active Directory, LDAP, or RADIUS. The download page offers x86_64 and aarch64 images for bare metal, virtual machines, embedded hardware, USB sticks, and SD cards; cloud images are available for AWS, Exoscale, and other providers. The project says it releases frequent security updates. Documentation, forums, mailing lists, and a bug tracker are available, and Lightning Wire Labs offers professional support.

Suricata is a free, open-source engine for network analysis, intrusion detection and prevention, and security monitoring. It uses signature rules to match known threats, policy violations, and malicious behavior, and can also detect traffic anomalies. A single instance can inspect multi-gigabit traffic using multi-threading and hardware acceleration. It logs HTTP requests, DNS queries and responses, TLS certificate and exchange data, and can extract files from network flows. Suricata automatically detects protocols such as HTTP on any port and applies relevant detection and logging. Its EVE output provides JSON event and alert data for Logstash and similar tools. The Open Information Security Foundation owns the code and supports the project. Suricata is licensed under GPLv2; OISF offers non-GPL licensing for organizations that want to use it in their products. Listed platforms include Linux, macOS, and Windows; downloads also include source for FreeBSD and UNIX and a Windows 64-bit installer. The listed stable release is 8.0.7, released September 15, 2026. Community support is available through a forum and Discord.
