Reduction in Firewall Rule Change Effort and Overhead
ROI Within the First Year
Engineer Time Reclaimed from Manual Access Reviews
The Challenge
This global travel management company operated a hybrid firewall and cloud estate spanning 76 firewalls and 484 cloud devices across Palo Alto, Cisco FMC, Fortinet, AWS, and Azure. Its previous NSPM platform struggled to resolve nested policy hierarchies and device group structures, delivered slow, days-long reporting, and left the organization without the visibility needed to prepare for PCI 4.0. Manual rule change and access review processes consumed roughly 30% of engineering time, creating both operational drag and audit exposure. The company sought to:
- Replace a legacy NSPM tool that couldn’t reliably resolve nested objects and device group hierarchies
- Simplify and accelerate readiness for PCI 4.0, alongside CIS, GDPR, and ISO requirements
- Eliminate manual effort from firewall rule change and access review workflows
- Gain unified, real-time visibility across a hybrid, multi-vendor firewall and cloud estate
The Solution
FireMon replaced the company’s incumbent platform with automated change workflows, continuous compliance assessment, and real-time visibility across the full hybrid estate. Native Panorama hierarchy and nested object resolution closed gaps the previous tool couldn’t handle, while rule cleanup eliminated redundant and shadow rules that had gone undetected. What had been multi-week change cycles became hours, and PCI 4.0 audit preparation shifted from a manual scramble to a continuous, automated process.
- Automated change workflows for rule design, deployment, and recertification
- Continuous compliance assessment mapped to PCI DSS 4.0, CIS, GDPR, and ISO
- Real-time visibility and traffic path mapping across the entire hybrid firewall estate
- Native Panorama hierarchy and nested object resolution
- Rule cleanup that closed blind spots left by the previous platform
FireMon gave us the visibility and automation we'd been missing, what used to take our team weeks now happens in hours, and we finally have a clear path to PCI 4.0 readiness.
