OT, SCADA and IoT Penetration Testing
Secure your critical infrastructure without disruption. CyberUnlocked delivers advanced OT, SCADA and IoT penetration testing using non-invasive, sensor-based techniques.
Understanding the Risks to Your Critical Infrastructure
As industries adopt digital transformation, Operational Technology (OT), SCADA, and IoT systems have become increasingly connected and increasingly targeted. These systems control critical infrastructure in energy, water, transport, manufacturing and more, where uptime and safety are paramount. Traditional IT-focused security measures don’t translate directly to OT environments, where legacy systems, vendor-specific protocols, and physical safety constraints complicate risk management.

Penetration testing tailored for these environments is essential. Without it, vulnerabilities can remain hidden until exploited – leading to downtime, data loss or even physical consequences. CyberUnlocked helps you uncover and address these weaknesses without compromising your operations.
Our Approach: Safe, Precise, Expert-Led
Zero disruption. Maximum insight.
Our approach includes:
Safe Discovery
Passive scanning and hardware-based sensors gather security insights without injecting traffic into production networks.
Actionable Recommendations
We deliver detailed reports prioritised by impact and risk, along with remediation guidance aligned to industry standards like ISA/IEC 62443 and the Australian Energy Sector Cyber Security Framework (AESCSF). We prioritise system integrity and operational continuity at every step ensuring your organisation can maintain availability while securing critical assets.
Common FAQs on
IOT, SCADA and IoT Penetration Testing
What makes penetration testing for OT, SCADA and IoT different from regular IT testing?
OT environments involve legacy hardware, real-time control systems, and vendor-specific protocols that differ significantly from IT systems. Unlike IT networks, availability and safety are top priorities in OT. A misstep could halt production or endanger personnel. That’s why CyberUnlocked uses passive monitoring and specialised hardware sensors to test these systems safely, ensuring insights without downtime or disruption.
Will penetration testing impact our operational systems?
No. At CyberUnlocked, we’ve engineered our testing methodology to avoid disruption. Using specialised sensors and passive data collection, we monitor traffic and behaviour without interfering with live systems. If any active testing is needed, it’s confined to isolated environments or conducted under strict change control procedures. Your systems stay online, safe and stable throughout.
How does CyberUnlocked ensure safe testing of legacy OT systems?
We understand the fragility of legacy systems and treat them with care. We avoid invasive scanning or traffic injection, and instead rely on out-of-band sensors and read-only network taps to collect security telemetry. This allows us to identify vulnerabilities while ensuring system availability and compliance with operational safety standards.
What standards does your testing align with?
Our methodology adheres to leading frameworks including ISA/IEC 62443, NIST SP 800-82, and the Australian Government’s Critical Infrastructure Risk Management Program (CIRMP). We also support alignment with the AESCSF and industry-specific regulatory requirements to help you maintain both security and compliance.
How do you handle vulnerabilities found in live systems?
If we discover vulnerabilities during testing, we document them with clear risk context and provide prioritised remediation steps. For critical issues, we alert your team immediately through agreed escalation paths, without taking any unauthorised action. Our reporting is designed to help you fix the issues without disrupting critical operations.
