Step 01
AX-Manage Event Timeline
AX-Manage shows events from controlled PLCs in a clear timeline, so operators can see what happened at each controller in the field.

AX-Box Gatekeeper.
A physical device between IT and the PLC. It controls agreed compatible protocols and mediates authorised interaction according to deployment policy, with planned installation and compatibility checks.
What it is02 / 05
A physical device. Between IT and the PLC. Doing one job, well.
AX-Box Gatekeeper is a hardware appliance designed from the opposite assumption to general-purpose IT security: don’t expect the operational layer to bend to you. Monitor traffic, enforce authorised access and mediate interaction according to deployment policy.
The same device protects baggage systems at Schiphol and is approved by the TSA for application on 450+ US airports.

AX-Manage in practice
How AX-Manage supports the AX-Box Gatekeeper.
AX-Box Gatekeeper sends its data to AX-Manage, the on-premises security platform for managing AX-Box Gatekeeper units and translating approved work permits into controlled PLC access.
AX-Manage console · 02
Step 02
AX-Manage PLC Control
AX-Manage connects work permits to PLC access. Authorised engineers can modify the controller, while unauthorised communication is blocked in real time. Urgent access requires supervisor approval.

Step 03
AX-Manage Change Control
Change Control tracks testing, commissioning, code changes and hardware differences. Asset managers can approve a version or restore the latest known-good version when a rollback is needed.
