IPFire

• Stateful Packet Filter

  Linux Netfilter firewall with zones, NAT, port forwarding, time-based rules, MAC rules, GeoIP country blocking, and SYN-flood rate limiting.

• Suricata IPS

  Deep packet inspection against Emerging Threats and Cisco Talos signature sets, with per-category rule selection and automatic ruleset updates.

• Network Segmentation

  Built-in LAN, DMZ, wireless, and guest zones with separate policy, which is how you actually put a web server behind IPFire.

• Squid Web Proxy

  Outbound proxy with transparent mode, URL filtering, MIME type blocking, traffic shaping, and LDAP, Active Directory, or RADIUS authentication.

• VPN Gateway

  IPsec, WireGuard, and OpenVPN for site-to-site and remote access, with hardware crypto acceleration and post-quantum key exchange on IPsec.

• Pakfire Add-ons

  Package manager for optional components including monitoring, backup tools, Guardian for log-driven blocking, and Tor.

F5 WAF for NGINX

• 7,800+ Attack Signatures

  F5's comprehensive threat signature database with continuous updates from F5's threat research team. Covers OWASP Top 10, CVE-specific signatures, and application-specific attack patterns.

• Declarative Security Policies

  WAF policies defined in JSON or YAML, designed for version control and CI/CD integration. Security-as-code approach where policies deploy alongside application code through the same pipelines.

• API Security

  Import OpenAPI/Swagger specifications to automatically enforce API contracts. Schema validation, parameter type checking, and rate limiting for REST, GraphQL, and gRPC APIs. Blocks requests that violate the API specification.

• ML-Powered DoS Protection

  Behavioral analytics using machine learning to detect and mitigate Layer 7 denial-of-service attacks. Learns normal traffic patterns and automatically identifies anomalous request rates, slow POST attacks, and resource exhaustion attempts.

• Bot Protection

  Multi-layered bot detection combining signature matching, anomaly detection, and behavioral analysis. Identifies credential stuffing bots, web scrapers, and automated vulnerability scanners.

• Kubernetes Ingress WAF

  Native WAF support in the NGINX Ingress Controller. Attach WAF policies to specific ingress resources for per-service or per-route security. Policies managed through Kubernetes CRDs and annotations.

• NGINX One Visual Editor

  The NGINX One console provides a GUI-based WAF policy editor, replacing the original CLI-only configuration. Security teams can create, modify, and monitor WAF policies through a web interface without writing JSON.

• Request and Response Inspection

  Inspects both incoming requests and outgoing responses. Response inspection catches data leakage, error messages that reveal application internals, and sensitive data exposure.
