Explore Imunify360 Features

Imunify360 provides:

  • Advanced firewall with cloud heuristics and artificial intelligence for detecting new threats and protecting all servers that run the software - Capable of defending against brute force attacks, DoS attacks, and port scans.
  • Intrusion Detection and Protection System -  Comprehensive collection of “deny” policy rules for blocking all known attacks.
  • Malware Scanning - Automatic scanning file systems for malware injection and cleaning up infected files.
  • Patch Management - rebootless Secure Kernel powered by KernelCare keeps the server secure by automatically patching kernels without rebooting the server.
  • Website Reputation Monitoring - Analyzing if a website or IPs are blocked by any blacklists and notifying if they are.
  • Proactive Defense - Proactive Defense protects websites running PHP against zero-day attacks by blocking potentially malicious executions automatically and with zero latency.

If a user violates the security rules (trying to enter a wrong password, etc.), then Imunify360 will automatically block access to this user’s IP address, adding the IP address to the Gray List.

  • Gray List – an auto-generated list of all the IPs blocked by the security software, based on Sensors alerts and alerts from the central server.
