Program Overview

AS400 Firewall Manager is Midland's answer to buyers who need more direct network control around IBM i traffic flows. Rather than leaving segmentation concerns entirely outside the platform, this type of tool lets administrators define and manage rule sets aimed at limiting inbound and outbound exposure.

It is especially relevant when IBM i security conversations expand beyond authentication into lateral movement, network policy, and service hardening. Buyers should treat it as part of a broader control model, not as a single complete security answer.

Best Fit

Best fit for IBM i teams that want a stronger network-segmentation posture around IBM i services and need policy visibility beyond generic perimeter assumptions.

What this program helps with

  • GUI-based management of inbound and outbound IBM i access rules
  • Support for network segmentation policy on IBM i workloads
  • More explicit control over traffic paths than default open-service assumptions
  • Useful complement to broader authentication and auditing initiatives

What to vet before shortlist

  • Map current traffic flows before enforcing restrictive rules
  • Review how policy changes are tested so production services are not disrupted
  • Confirm whether external firewalls and internal IBM i controls are aligned or conflicting
