Imunify360

• Managed WAF Rules

  ModSecurity-based WAF with proprietary rules maintained by Imunify's security team. Automatically updated to cover new WordPress plugin vulnerabilities, CMS exploits, and emerging attack patterns.

• Proactive Defense

  Real-time PHP script behavior analysis that detects and blocks malicious activity during execution. Catches zero-day attacks that signature-based WAFs miss entirely.

• Virtual Patching

  Blocks exploit attempts against known vulnerabilities in WordPress plugins, themes, and CMS software before official patches are released or applied.

• WebShield

  Reverse proxy layer that filters bot traffic and mitigates DDoS attacks using invisible JavaScript challenges instead of traditional CAPTCHAs.

• Automated Malware Cleanup

  Detects and removes malicious code from files automatically, preserving the original file integrity. Includes database scanning for CMS infections.

• Global Threat Intelligence

  Feeds from 57M+ protected domains. An attack blocked on one server instantly protects all other Imunify-protected servers worldwide.

• WordPress Plugin

  Dedicated WordPress plugin providing site-level security dashboard, scan results, proactive defense status, and malware details directly in wp-admin.

• Compromised Password Reset

  Automatically forces password resets when it detects that cPanel or WordPress credentials were used in an attack, breaking reinfection cycles.

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.
