ICS / SCADA / OT / IoT PENETRATION TESTING
ICS / SCADA / OT / IoT penetration testing: industrial security without halting operations
Testing of OT, ICS, SCADA and IoT environments with an emphasis on process safety. We check IT/OT segmentation, protocol exposure and remote access without risking production availability.
WHY IT MATTERS
In OT, a failure is not an error on a screen, it is a halted production line
Industrial control systems were designed for availability and continuity, not for resistance to attack. Increasingly, though, they are connected to the IT network, which opens a path from the office straight to the shop floor.
One case from our tests: the IT and OT networks were not genuinely separated, so from an ordinary office workstation an attacker could reach the control systems. In an industrial environment, such a segmentation flaw is a risk not only to data but to continuity and process safety.
WHAT WE CHECK
From the IT/OT boundary to a single device
We choose scope and method so as not to threaten availability or process safety.
OUR APPROACH
Process safety first, then the test
In OT, availability and human safety come first, so we do not transfer IT-world methods here unchanged. We rely on passive analysis and architecture review, and run active tests carefully, by agreement and where it is safe.
We work to IEC 62443 and NIST SP 800-82, mapping risk to the reality of an industrial environment. Every active action is agreed in advance, and sensitive tests run on backup systems or during shutdown windows.
COMPLIANCE
A test aligned with industrial-world standards
OT security has its own standards and growing regulatory requirements for infrastructure.
STANDARDS & CERTIFICATIONS
We work to recognized methodologies, not gut feeling
Every project is run by certified pentesters and based on public standards. That makes the result repeatable, auditable and comparable across vendors.
We share the full list of certifications and standards on request, together with a sample test scope.
HOW WE DO IT
A process tailored to the industrial environment
EVIDENCE
Numbers behind every promise
Every test is run by certified pentesters, and we document the result with reproduction steps, evidence and a verified remediation path. Proof, not a promise.
KNOWLEDGE
OT, ICS, SCADA and IoT penetration testing in practice
Why industrial systems are tested carefully
Industrial control systems are responsible for real processes: production, energy, critical infrastructure. A failure here does not just mean a loss of data, it can stop a production line or threaten the safety of people.
So we run OT tests differently from classic IT, with an emphasis on process safety and continuity. We define the scope and methods so we gain knowledge about the risk without risking the process itself.
What we check in OT and IoT environments
We analyze the architecture, the separation of the OT network from IT, industrial protocols and the protection of control and IoT devices. We check whether the production world is really separated from the office network or only in theory.
We look at the touch points through which an IT attack could move into OT, because that is the most common route today. Where testing on a live system would be too risky, we work on test environments or configuration analysis.
Why IT and OT separation is crucial
Many serious industrial incidents start in an ordinary office network, from which the attack moves into the control systems. If these two worlds are not properly separated, a single compromised IT account can reach all the way to the production process.
So the heart of the test is checking whether the boundary between IT and OT really exists and works. That is often more important than a single vulnerability in the device itself.
What you get and when to test
The report describes the weaknesses found with a risk rating that accounts for the impact on the process, and recommendations matched to the realities of an industrial environment. We order priorities to protect continuity, not just to close a list.
OT tests are worth planning during infrastructure modernization, connecting new devices or integrating with IT, and in the context of regulatory requirements for critical infrastructure. We always match the scope to the sensitivity of the process.
