   ManageEngine Firewall Analyzer

   Best for firewall policy management

   • Free demo available
   • From $33/user/month

   Visit Website

   

   ManageEngine Firewall Analyzer is a firewall log management tool that helps you audit rules, monitor VPN and proxy activity, and run compliance checks—all without needing extra hardware. While it’s not a traditional intrusion detection system (NIDS), it gives you visibility into traffic behaviour and rule usage that can help you spot suspicious patterns and tighten your firewall configurations accordingly.

   Why I Picked ManageEngine Firewall Analyzer:

   I picked this tool for teams that want deeper insight into how their firewall policies actually function. If you're tasked with managing a multi-vendor firewall setup and need to make sure outdated or overly permissive rules don’t slip through, this tool gives you the visibility to do just that. It’s also helpful if you’re under pressure to produce compliance reports or track changes across multiple devices. Just keep in mind: while it supports real-time alerts for config changes and usage trends, it doesn't analyze raw network packets the way a NIDS does.

   Standout features & integrations:

   Firewall Analyzer lets you group internet activity by user category (like streaming or file sharing), flagging higher-risk behaviour for review. You can drill into VPN session logs by user or group and get bandwidth data for proxies too. For audits, it generates reports based on standards like PCI-DSS and ISO 27001. It integrates with other ManageEngine tools like Log360, Endpoint Central, Patch Manager Plus, and M365 Security Plus, giving you a broader security stack if needed.

   Pros and Cons

   Pros:

   • Provides detailed insights into firewall traffic and user activity
   • VPN tracking and bandwidth management
   • Real-time monitoring capabilities help identify unusual traffic patterns

   Cons:

   • Requires regular updates and maintenance
   • Slower patch responses for third-party software vulnerabilities
