Cybersecurity assessment services

OT, IoT, and SCADA testing

Risk-led testing of operational technology, IoT, and SCADA environments without disrupting production.

About the service

Service Description

OT, IoT, and SCADA testing is a risk-aware review of your operational technology, industrial control systems, and connected-device estate for the kinds of flaws that can disrupt production, damage equipment, or threaten safety.

Why this service matters

The business case

OT incidents don't just cost data — they can stop a plant, damage equipment, and threaten human safety. Standards like IEC 62443 now require regular, documented testing; insurance and supply-chain audits expect it as well.

What is delivered

Assessment deliverables

Each assessment produces a working set of artefacts that the customer's engineering, security, and leadership teams can act on. The exact list is calibrated to the scope and framework alignment.

  • Non-disruptive assessment of OT/ICS environments
  • Purdue model and zone-conduit review
  • IoT device firmware and protocol review
  • Remediation roadmap aligned to IEC 62443

Delivery method

Axpert Service Delivery Model
