Is your system secure, or just assumed to be?
Attackers look for the easiest way in. Whether it’s a misconfigured cloud service, a legacy system or an overlooked endpoint, small gaps can lead to big consequences.
Our pentesting services simulate real-world attacks to uncover your weak spots before someone else does. For over 20 years, organizations across all sectors have trusted us to test everything from core infrastructure to connected devices.
Know your weakness
Get clear insight into where attackers could break in, before they try.
Strengthen your defences
Receive practical, prioritized recommendations to fix what matters most.
Stay ahead of attackers
Our experts apply the latest attacker tactics, so you can anticipate the next move.

Why pentesting matters
Security measures alone aren’t enough. Attackers evolve fast, exploiting both outdated systems and newly discovered flaws your team may not see coming.
Pentesting reveals how your defences hold up under pressure. Our ethical hackers simulate real-world attacks to uncover the risks that matter most, before attackers get the chance.
We combine broad vulnerability assessments with in-depth penetration testing to give you a full picture:
- Vulnerability Assessments find as many weaknesses as possible
- Pentesting shows how far an attacker could get
Together, these tests help you take action where it counts.
What we test
Your systems are unique, and so are the risks. That’s why our pentests are tailored to your infrastructure. We test across IT, OT and IoT environments, using internationally recognized standards. See detailed lists below.
1. IT security testing
We test your applications, networks and infrastructure to identify real-world risks and weak spots. If you manage multiple systems, we recommend starting with a threat modeling session. For instance we offer:
2. OT security testing
Operational Technology environments demand a different approach. Our specialized OT team helps you secure industrial systems where availability and continuity are critical.
- OT Vulnerability Assessment and Penetration Testing
- OT Threat Modeling
- OT Perimeter Assessment: evaluates the security of the boundary between Information Technology (IT) and Operational Technology (OT) systems
- ICS Cyber FAT-SAT: an extension of the conventional FAT/ SAT with a focus on cybersecurity
3. IoT security testing
Smart devices (IoT) often combine physical and digital vulnerabilities. We assess both the hardware and the software, from embedded firmware to cloud backends.
-
IoT Assessment
Evaluates the security level of the (I)IoT devices and back-end services (customer isolation, cloud-based provisioning system, etc.)
-
IoT threat modeling
Helps identify the best-suited secure design for devices and back-end services
- Consumer IoT evaluation and certification
Testing Aligned with International Standards
Security testing only has value if it's clear, repeatable, and relevant. That's why we follow established international standards, tailored to your environment, sector and objectives.
We use standards such as:
- ASVS / M-ASVS – for web and mobile application security
- OWASP Testing Guide – widely adopted best practices
- SANS Top 25 – to identify high-impact coding errors
- Sector-specific frameworks – including PCI-DSS, BIO, DigiD and more
Our goal is to deliver results you can trust, backed by proven methods, not assumptions.
How we test: different types of pentesting
01
Black-box testing
We simulate an external attacker with zero inside knowledge. This test shows how easy it is to break in, just like a real-world threat actor would attempt.
02
Grey-box testing
Here we combine outside-in testing with partial access (like user credentials). This lets us assess what an attacker could do after gaining limited access.
03
Crystal-box testing
In this deep-dive approach, we test with full knowledge of the system, including source code or config details. Ideal for uncovering issues in logic, cryptography or custom applications.
In practice, we often combine these methods to match real attack scenarios. For example, we may start black-box, move into grey-box using known credentials, and apply crystal-box techniques for targeted components.
Beyond a Scan: How We Deliver Quality
Anyone can run a scan. We go further, with hands-on testing, expert interpretation and full transparency.
Highly skilled testers
Our team performs hundreds of tests each year. All testers are certified (OSCP, OVSE, eCPPT, GIAC GPEN and others) and stay up to date with attacker tactics.
Certified and trusted
- We’re accredited by CREST and were the first to achieve the Dutch ‘CCV-keurmerk Pentesten’.
- Our product security lab is certified for Common Criteria.
- We’re also one of the few pentest providers approved under the BSPA scheme by the Dutch government.
- We have obtained a SOC 2 Type 1 report. SOC 2 (System and Organization Controls 2) is a widely recognized auditing standard that evaluates the security, availability, processing integrity, confidentiality, and privacy controls of a service organization.
Transparent reporting
Every test is reviewed by at least two senior testers: our 4(+)-eye principle.
Even if no vulnerabilities are found, you receive a detailed report you can verify, share and build on.
