ARKARA-GATE
Overview

OEM engineers often need remote access to turbines, DCS and PLCs, and that is now one of the most exploited paths into critical infrastructure. RA-Gate replaces ad-hoc VPNs and remote-desktop tools with a brokered gateway. Every session is requested, approved by the plant, time-boxed, protected by MFA, limited to specific assets and protocols, and fully recorded.

Plant operators can watch live and terminate any session instantly.

Key features

Approval workflowVendor requests, plant approves, and access expires automatically.
No inbound portsOutbound-only connector from the plant. No exposed VPN.
Session recordingVideo-style recording of RDP/SSH/VNC/web sessions with keystroke search.
Least privilegeAccess limited to named assets, protocols and time windows.
MFA & identityTOTP, smart card or FIDO2. Integrates with AD/LDAP.
Live supervisionShadow, pause or kill sessions in real time.
