[Secomea Prime](https://cybersectools.com/tools/secomea-prime) Secomea Prime is a remote access and data collection gateway platform for Operational Technology (OT) and Industrial Control System (ICS) environments. It connects industrial equipment such as PLCs, HMIs, SCADA systems, and legacy serial devices to enable secure remote access and machine data collection, available as either a dedicated hardware gateway or a software program. The platform provides browser-based remote access to machines without requiring plugins or additional client software, supporting protocols such as RDP, VNC, and SSH. It includes user access management features such as drag-and-drop permission assignment, bulk group management, and hierarchy-based privileged access roles, with SCIM-based integration to external identity providers for SSO. Secomea gateways use outbound-only, TLS-based VPN connections to link up to 100 industrial devices via Ethernet, serial, or USB using native industrial protocols (Modbus, PROFINET, EtherCAT, Ethernet/IP, OPC UA, Siemens S7, MQTT). Collected machine data can be forwarded to cloud platforms for further processing and analysis. A store-and-forward database caches data locally to reduce data loss during connectivity interruptions. The Vulnerability Hub component tracks the security status of deployed gateways across sites, providing a vulnerability score based on firmware and hardware currency, along with recommended remediation steps, firmware update tracking, and end-of-life/end-of-support notifications for hardware models.
