OT security is often split across IT, automation teams, vendors and individual projects. Everyone owns a part of the environment, but too rarely does anyone own the whole security picture.
That gap matters in industrial operations. Assets change, the need for remote access keeps increasing, and technical requirements increasingly affect production, safety and continuity. Managing this reality requires OT‑specific expertise, practical engineering know‑how and security discipline within the same team.
ESFABRIK was formed to close that gap: a Nordic OT cybersecurity practice for organizations that need focused ownership of operational security, not an IT-first model extended into production.

Security without disruption.
Availability is a requirement in every decision and implementation. Stronger security cannot come at the expense of operational continuity.

Regulatory clarity, audit-ready.
NIS2, ISO 27001, and IEC 62443 shape how we assess, design and deliver. We build in the required controls and evidence, then close remaining gaps.
