Penetration testing of OT/ICS systems

We’ll verify that your production control systems can be realistically hacked and show you what avenues attackers can use to cripple your company. In a safe and controlled manner, our ethical hackers will simulate a real attack on your OT infrastructure to identify viable paths to key resources.

Tests for key critical infrastructure operators

Certified ethical hackers (OSCP).

Safe methodology that does not disrupt production


To hackers, your production control system is just another computer on the network.

The merging of information technology (IT) systems with operational technology (OT) has paved the way for Industry 4.0, but at the same time exposed you to new, previously unknown risks. Your control systems, which have operated in isolation for years, have become a target for hackers.

In 8 of the 10 industrial networks audited, we find at least one non-obvious IT-OT attack path.

True story: how a service technician’s laptop bypassed a million-dollar firewall

A multinational manufacturing company invested heavily in state-of-the-art firewalls separating the IT and OT networks. In theory, the systems were fully isolated.

During penetration testing, our team discovered that one laptop, used by a third-party service company, had permission to connect to both the public guest Wi-Fi (on the IT network) and the diagnostic port on the key machine controller (on the OT network). Through a simple phishing attack on the service technician, we gained control of his laptop, thus creating a “bridge” to bypass all firewalls and get into the heart of the production network.

Your security measures are only as strong as their weakest, often non-obvious point. Only a simulation of a real attack can find it before the criminals do.

Are you willing to bet the continuity of your production on the assumption that no one will find that one forgotten path to your OT network?


Our solution: the ultimate test of your security features

An OT penetration test is a controlled experiment that answers one question: is it possible to break into our production systems and what might be the result? Unlike passive audits, we actively try to break through your defenses to show you what is really possible. All this in a way that is fully secure for your operations.

Our approach is based on 3 pillars:

Simulation of realistic attack scenarios

We use the same techniques (TTPs) as hacking groups that specialize in attacks on industry. We show you step-by-step how you can take control.

Flexible test variants

We tailor activities to your goals. We conduct black box (no knowledge), grey box (partial knowledge) or white box (full knowledge) tests.

Guarantee of security and continuity

Our priority is the safety of your production. Every action is carefully planned and carries no risk of disrupting your processes.


Our controlled penetration testing process in 5 steps

Each test is a precisely planned project, minimizing risk and maximizing value.

Step 1

Definition of objectives and rules of the game

Together, we define what the target of the attack is (e.g., “access to the SCADA server”) and what the rules are – what we are allowed and not allowed to do (Rules of Engagement).

Step 2

Reconnaissance and mapping of attack paths

We identify potential entry points and vulnerabilities, creating a map of possible routes an attacker might take.

Step 3

Controlled security breach attempts

We start simulating the attack, trying to exploit the vulnerabilities found to gain access, escalate privileges and reach the target.

Step 4

Documentation of attack paths and report

We document every successful step, creating a detailed description of a viable attack path. We develop a report with specific recommendations.

Step 5

Presentation of results with demonstration (PoC)

We present the results to management and the technical team, often with a practical demonstration that shows the reality of the threat.


What does your business gain? Real knowledge instead of theory

An investment in penetration testing is an investment in the truth about the state of your security.

Verification of the real effectiveness of safeguards

Get hard proof of whether your security investments (firewalls, IDS systems) actually work when faced with a creative attacker.

Exploring non-obvious attack paths

Identify multi-stage attack paths invisible to automated scanners. Understand how harmless vulnerabilities create a critical attack chain.

An argument to justify the investment

Use clear test results to convince management of the need for further investment in specific areas of OT security.

The best training for your team

The practical test is the best and safest exercise for your SOC/IT team, allowing them to test procedures under controlled conditions.

Stop relying on theory. Check the real-world resilience of your company.
