THE SECURET METHOD / OT SECURITY
Protect operations without compromising safety.
Work outward from critical processes, operational constraints and recovery needs—not a generic IT checklist.

Recover
Coordinated response and restoration planning
Safety, availability and operational ownership take priority throughout OT risk treatment.
Illustrative delivery model. Activities are tailored to the engagement scope, environment and risk profile.
WHO THIS IS FOR / BUSINESS CONTEXT
When organisations call us.
Who this is for
Critical infrastructure operators, asset owners, engineering managers, operational risk leaders and OT/IT security teams.
Common triggers for an engagement include:
- You cannot confidently account for controllers, assets and remote connections
- Third-party vendors access production networks using poorly governed pathways
- IT and OT network boundaries are unclear, and changes may disrupt operations
ENGAGEMENT SCOPE
What we examine and design.
Work is proportionate to the system, its operating context and the decisions you need to make.
Passive asset discovery and OT network architecture review
Industrial DMZ and controlled-conduit segmentation design
Vendor privileged and remote access review
Operational resilience and configuration recovery planning
SOCI Act risk management program architecture where relevant
IEC 62443 zone and conduit assessment
Safety-led remediation sequencing with maintenance windows
OUR APPROACH
How we deliver.
Operations personnel define safety and availability constraints. We favour passive visibility and coordinate modifications with asset owners and vendors.
Standards and platforms
NIST SP 800-82 Rev 3 · IEC 62443 concepts · SOCI Act · ASD ISM
Where we draw the line.
Active testing on production control systems is never undertaken without explicit safety approval, authorisation and an agreed scope.

Questions worth asking.
Answers are scoped to the service described here, not guarantees for an individual environment.
Can you assess OT without disrupting production?
Usually we start with workshops, documentation, passive traffic review and approved vendor information before recommending controlled changes.
What should an industrial operator secure first?
Understand asset criticality, remote vendor access and IT/OT trust boundaries. Sequence implementation to protect safety and continuity.
