Approved individuals can access the approved device for the approved duration. Remote access for OT.
Secomea's remote access service is designed for the remote maintenance and monitoring of production equipment. At its core is the principle of zero trust, allowing approved individuals to connect to approved devices only for approved periods of time. It meets the specific control requirements of operational technology (OT) that traditional IT VPNs and jump servers cannot address. The configuration consists of three components: the IIoT gateway SiteManager placed on the device side, the Access Management server in the cloud that centrally manages permissions and records, and the LinkManager, a connection client used by operators from their PCs or browsers. Since connections are always initiated from the factory side outward, there is no need to open incoming ports on the firewall, allowing for implementation without disrupting existing network configurations or the layers of the Purdue model.

Applications/Examples of results
【Remote Maintenance for Equipment Manufacturers】Connect to equipment without changing the factory network of the client, allowing for adjustments and troubleshooting without on-site attendance or business trips. 【External Access Control for Factories】Consolidate the increased connection methods by vendor, and centrally record who connected to which equipment, when, and what actions were taken. 【Response to Client Audits and Internal Controls】Strictly manage audits and explanations to clients through applications for connection reasons and durations, administrator approvals, and recording of operation screens. 【Centralized Management of Multiple Locations】While understanding access conditions across locations, the decision to permit connections remains with the on-site personnel. Used by over 8,000 companies and more than 100,000 users, with over 400,000 units of SiteManager shipped. Founded in Denmark in 1999, we continue to focus on remote access for the manufacturing industry.
