OT Security / Secure OT remote access
Secure OT remote access.Identity, destination and time belong together.
Maintenance needs access, but it does not need a permanently open tunnel into production. We structure roles, approvals and technical paths to keep remote access practical for maintenance and traceable for the operator.
Scope of service
What you receive.
This service fits shared VPN accounts, permanently reachable vendor routers, ad-hoc approvals and unclear ownership that need to be replaced. We map internal and external maintenance scenarios, destinations, identities, approval and emergency access. Product selection follows this workflow rather than defining it.
Defined maintenance scenarios
Roles, organisations, people, target assets, required protocols and permitted periods are structured. Regular access, on-call support and emergencies remain visibly distinct.
A constrained technical path
Authentication, approval, the mediation or jump component, destination restrictions and network segmentation are designed together. Direct reachability exists only where the operational need justifies it.
Traceable sessions
Named access, approval events and technically available logging are placed into a retention and review model. Privacy and workforce consultation remain operator responsibilities.
A controlled transition
Existing remote paths are inventoried, prioritised and retired deliberately after a successful pilot. Recovery and emergency access remain consciously available and documented until acceptance.
The delivery path
Three controlled steps.
- 01
Order access and roles
Review vendors, internal teams, target assets, protocols, identities and current exceptions. Prioritise critical maintenance scenarios.
- 02
Pilot the control path
Validate authentication, approval, destination binding, logging and failure behaviour with a limited set of users and assets.
- 03
Migrate and operate
Move further access after approval, close legacy paths deliberately and hand over lifecycle, review and emergency procedures.
What we agree before starting
Technical logging is not legal approval for employee monitoring or data processing. The operator defines permitted use, retention and consultation. Vendor compatibility, cloud requirements, licences, support, identity sources and emergency operation are reviewed before product selection and scoped in the proposal.
Good to know
Your questions. Clear answers.
Can external vendors connect without a corporate account?
That depends on the selected identity and invitation model. We design around named, traceable identities and avoid shared accounts. Onboarding, verification and removal of external users belong in the operating process.
Is session recording always required?
No. Need, technical capability and permissibility depend on risk, protocol, platform and organisational requirements. Identity, approval, destination and time should at least be traceable; more detailed recording is a separate decision.
What happens if the access platform fails?
The target design needs a deliberate incident and emergency procedure. A restricted break-glass path, local operation or another route may fit; it is planned, protected and reviewed with the operator.
Let’s discuss your requirements
A few details are enough to begin.
You do not need a finished design. We establish the need, boundaries and a dependable next step.
