IoT & OT Penetration Testing

Connected devices, firmware and operational technology environments.

Security assessment of connected devices, firmware, wireless protocols and industrial control environments with safety-first methodology.

Typical timeline
Typically 2–4 weeks depending on device count
Business benefit
Secure connected products and production environments without risking uptime.

Overview

What IoT & OT Penetration Testing covers

Connected devices combine hardware, firmware, radio protocols and cloud backends. A weakness in any layer can affect an entire deployed fleet.

In operational technology environments safety and availability come first: testing is passive by default and escalates only with explicit authorisation.

The problem we solve

Device fleets are hard to patch, and OT networks were designed for reliability rather than adversarial resistance.

Scope & outcomes

What we test and what you receive

Scope coverage

  • Firmware extraction and analysis
  • Hardware interfaces and debug ports
  • Secure boot and update integrity
  • Wireless and radio protocol security
  • Device-to-cloud authentication and provisioning
  • Mobile and web management interfaces
  • OT protocol exposure and segmentation
  • IT/OT boundary and remote access paths

Key benefits

  • Reduced fleet-wide compromise risk
  • Verified update and provisioning integrity
  • Stronger IT/OT segmentation
  • Product security evidence for customers

Deliverables

  • Executive summary written for business stakeholders
  • Technical findings with severity, CVSS and reproduction steps
  • Evidence: requests, responses, screenshots and payloads
  • Prioritised remediation roadmap
  • Remediation support session with your engineers
  • Re-test report and closure statement

FAQ

IoT & OT Penetration Testing questions

No. OT testing is passive unless you explicitly authorise active testing, and active work is preferably performed on a lab or replica environment.
