OT/ICS security readiness for PLC/SCADA and IT/OT environments.

Short positioning

This service is OT/ICS security readiness from an automation engineering perspective. It is not presented as pure cybersecurity consulting, compliance certification or a guarantee. The focus is practical work that helps PLC/SCADA and IT/OT teams understand assets, backups, remote access, segmentation boundaries and commissioning security practices.

Typical problems we solve

Many industrial sites know that OT security matters, but the practical starting point is often unclear. From an automation perspective, the first questions are simple: what assets exist, where are the backups, how is remote access handled, and what happens during commissioning or recovery?

• PLC/SCADA assets are not clearly inventoried
• Backups and recovery steps are incomplete or untested
• Remote access is useful but not well controlled
• Network segmentation is unclear between IT and OT
• Commissioning work creates temporary security gaps
• Engineering laptops, HMI stations and PLC projects are not documented consistently

Systems and platforms covered

The work can involve PLC/SCADA environments, Siemens and CODESYS-based systems, HMI/SCADA stations, engineering laptops, industrial Ethernet, remote support paths, edge systems and IT/OT boundaries. It can also relate to imported European machinery where remote OEM support, backups and project files must be controlled more clearly.

The language is intentionally careful: readiness support means practical preparation and risk reduction. It does not promise compliance results, certification, breach prevention or a fixed security outcome.

How support works

A readiness review can start remotely with architecture information, asset lists, backup status, remote access method and known operational constraints. The output should be practical enough for engineering and maintenance teams to act on.

The review can identify missing backups, unclear access paths, undocumented engineering stations, unmanaged temporary connections, weak handover steps and segmentation questions. The result should be a prioritized list of actions rather than a theoretical report that no one uses on the plant floor.

Remote vs onsite support

Remote support is useful for reviewing architecture diagrams, asset lists, backup practices, remote access methods, commissioning procedures and IT/OT boundary questions. It can help a team define the first readiness baseline without interrupting production.

Onsite support is useful when the real cabinet layout, network topology, engineering laptops, unmanaged switches, HMI stations or machine access practices must be checked directly. Onsite work should be coordinated with plant safety and operations responsibility.

Deliverables / what the customer gets

• Asset inventory structure for PLC/SCADA and OT equipment
• Backup and recovery observations
• Remote access and segmentation review notes
• Commissioning security checklist
• Practical follow-up actions for OT, maintenance and engineering teams

Good fit / not a good fit

Good fit: plants that need a practical OT readiness baseline, backup review, asset inventory support, remote access cleanup, commissioning checklist support or IT/OT boundary discussion.

Not a good fit: requests for legal compliance certification, penetration testing, fixed cybersecurity outcomes or enterprise-only IT security work without automation context.

Related case studies or examples

A typical example is a plant that has remote OEM access but no clear record of who can connect, where backups are stored or what happens if a PLC project is lost. Another example is a commissioning project where temporary network changes are made quickly and then never documented. The IT/OT diagnostics example shows how network clarity supports readiness work.
