OT

Option delivers end-to-end OT management covering governance, change control, vendor coordination, risk assessments and compliance across NIS2, NOG-104, ISO 27001, IEC 62443, BEK260, CRA and CER. We establish and lead your OT Change Advisory Board, manage incident and ticket workflows, maintain your risk register and ensure full documentation and audit readiness, including preparation for authorities such as Havtil. Regular offshore visits verify that procedures are followed during both vendor maintenance and daily operations.

Our Secure Login solution provides hardware-based remote access designed and manufactured in Scandinavia, originally built for critical infrastructure requiring access to closed OT systems. The unit connects via your OT network or a separate VLAN and establishes a direct, end-to-end encrypted IP tunnel with no inbound internet exposure. Built-in LTE means no static public IP, dramatically reducing the attack surface. Every session requires multi-factor authentication, is time-bound and fully logged. Each vendor receives unique credentials with role-based access rights, eliminating shared passwords entirely. The hardware itself is hardened with burnt fuses, no service ports, and firmware that can only be updated over-the-air through our private cloud. Independent penetration testing has been carried out by Nixu, ICS Range and Devoteam.
