Firewall review for ISO 27001
ISO 27001 requires that network security controls are managed, documented and reviewed. FirewallScan automates FortiGate firewall review and produces the evidence your auditor expects.
What ISO 27001 expects from your firewall
ISO 27001 and its Annex A controls (notably around network security and secure configuration) expect organizations to manage network controls, enforce least-privilege access, and review configurations regularly as part of a working information security management system.
Crucially, auditors want evidence: not just that your firewall is configured well, but that you review it on a defined cadence and act on what you find. A firewall that is never formally reviewed is a finding waiting to happen.
- Network controls managed and configured securely
- Least-privilege access across network boundaries
- Regular, documented review of firewall configurations
Where firewall review fits in ISO 27001
Several Annex A control areas touch directly on how firewalls are configured and reviewed.
Network security
Controls expect networks to be managed and protected, with segmentation and access aligned to risk.
Secure configuration
Systems, including firewalls, must be configured securely and maintained against a known baseline.
Evidence & review
An ISMS requires that controls are monitored and reviewed — and that the review is documented.
How FirewallScan helps
Turn firewall review into ISO 27001 evidence
FirewallScan reviews your FortiGate configuration against best-practice baselines, surfaces deviations and least-privilege gaps, and produces a documented report you can retain as audit evidence.
Run it on a regular cadence and you generate a continuous trail demonstrating that firewall configurations are reviewed and improved over time — exactly what an ISO 27001 auditor wants to see.
- Automated review against a secure configuration baseline
- Documented, retainable evidence of regular review
- Least-privilege and segmentation gaps surfaced automatically
