The Best Firewall Optimization Tools

Firewall remains an indispensable tool in network security, serving as the first layer of defense, and filtering enormous amounts of traffic across the enterprise networks

However, firewall policies and configurations constantly change and modify today’s dynamic business environment. In this article, we will review the six best firewall change management solutions, hopefully, this will guide you in choosing the right one for your business.

Here is our list of the best Firewall Optimization tools:

1. ManageEngine Firewall Analyzer EDITOR’S CHOICE Αn enterprise-class, web-based, agentless software for firewall optimization, change management, traffic analysis, security, and bandwidth monitoring, compliance audit, and reporting for firewall and other network security tools. Start a 30-day free trial.
2. AlgoSec Α firewall policy management company that enables organizations to automate and enforce security policies across firewalls, routers, and virtual private networks (VPNs).
3. Tufin A security policy management company that enables organizations to automate their security policy changes, risk management, provisioning, and compliance across multi-vendor, hybrid platforms while improving security and compliance.
4. Skybox Firewall Assurance A centralized firewall management solution that provides comprehensive automation of firewall optimization, compliance checks, and management tasks across different firewall vendors and complex rulesets.
5. SolarWinds Security Event Manager A network security tool that helps organizations detect unusual traffic patterns and network attacks and improve network security.
6. FireMon A network security management tool that provides real-time visibility and control of security policy across on-premises and cloud environments and helps organizations maintain compliance and centralize security policy orchestration.

Over the years, these firewalls may accumulate thousands of rules, objects, and bloated rulesets. This adds complexity to the daily management and operation of the firewall. In addition, complex firewall configurations negatively impact its performance, resulting in decreased hardware lifespan.

With the growing complexity of today’s network infrastructure, hundreds of firewalls from different vendors, thousands of routers and switches, and private clouds, it’s nearly impossible to analyze and optimize firewall and router configurations manually. Existing manual approaches are too slow and error-prone to be effective.

This is where automated firewall optimization tools come into play. With a firewall optimization tool, you can automatically analyze firewall rulesets, logs, and routing information to provide organizations with actionable recommendations for cleaning and optimizing network security policies across heterogeneous networks.
