ISO 27001 Firewall Security Audit Checklist: Essential for Robust Network Security.

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.
