Last updated June 3rd, 2024 by Avigdor Book

An ISO 27001 firewall security audit checklist is indispensable for your firewall to adhere to cybersecurity best practices but also helps strengthen your security policy. Regular audits help identify vulnerabilities, assess network security, and manage risks effectively.

The cybersecurity landscape is evolving rapidly, with organizations continuously seeking robust solutions to manage and secure their networks. The cybersecurity team at a large U.S. utilities company evaluated several options to manage its firewall environment effectively. They prioritized flexible automation, scalability, and extensive integrations. The aim was to ensure the company’s security policy was upheld during every rule exception request and to implement and track changes seamlessly across all devices, including firewalls, routers, switches, and F5 and NSX devices. “Tufin checked all the boxes,” noted the Senior Cybersecurity IT Solutions Engineer.

Network Changes in Days, Not Months

With Tufin’s network security solutions, the utility company significantly reduced the time and effort required to manage firewall rules and change requests. The Solutions Engineer highlighted, “The value becomes apparent when a workload that took 40 people, now takes about 5 people.” This efficiency is critical for maintaining a robust security policy while meeting business demands.

Tufin’s automation capabilities streamline firewall change management, ensuring that changes are implemented correctly and documented meticulously. This approach not only saves time but also minimizes security risks associated with manual configurations.

Automated, Streamlined Compliance Efforts

The utilities company also benefited from Tufin’s automated compliance features. The Cybersecurity Manager explained, “We save countless hours on rule cleanup and compliance reporting, and we can give management visibility without pulling one of our valuable team members from critical tasks.” Tufin’s firewall change automation capabilities ensure that all access changes are reviewed and tested against the company’s security policy, enhancing the organization’s security posture.
