Firewall security for manufacturing & OT
Manufacturing networks blend IT and OT — and that mix creates unique exposure. FirewallScan helps you keep FortiGate policies tight, segmented and reviewable without slowing operations.
Where manufacturing and OT environments get exposed
OT networks were built for availability and uptime. Over time, remote access exceptions, vendor tunnels, and temporary “just make it work” rules become permanent — and segmentation boundaries erode.
Add shared services (AD/DNS), industrial protocols, and mixed legacy systems, and the firewall policy quickly becomes too complex to review manually. The result is overly permissive access paths that attackers can use to pivot from IT to OT — or between production zones.
- IT/OT convergence and blurred segmentation boundaries
- Remote vendor access and long-lived exceptions
- Legacy devices and protocols that are hard to lock down safely
- High change volume with limited time for thorough review
Reduce blast radius without slowing production
Manufacturing security is often about limiting movement and tightening trust boundaries. Small policy gaps can create large exposure across production lines.
Zone sprawl
Over time, policies between “temporary” zones become permanent. FirewallScan highlights overly broad inter-zone access and segmentation gaps.
Remote access creep
RDP/SSH/VPN access expands as more vendors connect. FirewallScan flags management exposure and permissive services across zones.
Protocol over-permission
Industrial protocols and shared services often get opened too widely. FirewallScan identifies rules that allow “any” services or unnecessary reachability.
Why FirewallScan helps
Turn complex policies into a prioritized hardening plan
FirewallScan analyzes your FortiGate configuration and surfaces misconfigurations, overly permissive rules, and segmentation issues — prioritized by risk. Each finding includes the evidence and remediation steps engineers can apply safely.
Because it runs in minutes, you can review policies after each change window and keep OT boundaries intact over time — without relying on a once-a-year manual review.
- Segmentation and least-privilege gaps surfaced automatically
- Clear evidence snippets and remediation steps per finding
- EU-first hosting and self-hosted options for sensitive environments
