ETAS IT & OT Cybersecurity services

Secure every layer of your operations - before an attacker does.

IT & OT Security Services by ETAS help you find and fix security weaknesses across your enterprise IT and operational technology. From web applications, APIs and cloud to the industrial systems on your factory floor, our consultants and offensive-security specialists test your defenses the way real attackers would — and guide you to close the gaps.

Your benefits

What you gain when security testing and consulting come from one expert team.

Reduce real-world risk

Find and fix exploitable weaknesses before attackers do.

Meet compliance, build trust

Evidence-based results that support ISO 27001, IEC 62443 and EU Cyber Resilience Act (CRA) readiness.

One trusted partner

IT and OT, testing and consulting, coordinated by a single expert team.

Our services

From offensive testing to hands-on consulting — coverage across enterprise IT and the factory floor.

Practical security testing from the attacker's point of view — across web applications, APIs, cloud, mobile and infrastructure. Our specialists manually exploit weaknesses to show what a real attacker could reach, and exactly how to fix it.

Simulate real-world attacks and sharpen your defenders in the same exercise: Red finds the gaps, Blue defends, Purple unites both to make your organization measurably harder to breach.

Know your risks before you build or ship. Using a systematic, standards-based approach, we identify, analyze and prioritize the threats to your systems and data — so you invest where it matters most.

Expert, hands-on guidance across the security lifecycle: architecture and design reviews, secure-by-design, hardening and ISO 27001-aligned support embedded in your projects - from consultants who also test and break systems for a living.

Your APIs are a prime target. We assess your API design, specifications and real-world exposure against the OWASP API Security Top 10 to protect your interfaces and the data behind them.

Secure your cloud foundation. We review and help harden your AWS, Azure or Google Cloud configuration and architecture against best practice and provider baselines — catching misconfigurations before they become incidents.

Security that reaches the factory floor. We assess and protect the operational technology behind your production and infrastructure — OT/ICS penetration testing, IT/OT network segmentation and risk analysis aligned to IEC 62443 — without disrupting operations.

AI-assisted penetration testing with human-in-the-loop

We pair AI-driven reconnaissance, scanning and analysis with expert manual validation. AI delivers broader, faster coverage; our pentesters confirm every finding, pursue complex attack chains and eliminate false positives — so you get speed and accuracy, not one at the expense of the other.

Aligned with what matters to you:

ISO 27001
IEC 62443
OWASP & API Security Top 10

Why ETAS

ETAS brings together offensive-security specialists, experienced consultants and an in-house security lab to secure IT and OT environments end to end. We test to internationally recognized standards and deliver globally, with local teams and support close to you.

Frequently asked questions

What's the difference between a penetration test and red teaming?

A penetration test systematically finds and exploits weaknesses within a defined scope and reports exactly what to fix. Red teaming simulates a real adversary against your people, processes and technology to test how well you detect and respond. Many organizations start with penetration testing and progress to red and purple teaming as their security matures.

How does AI-assisted penetration testing stay accurate?

AI accelerates reconnaissance, scanning and analysis, but a human expert stays in the loop: every finding is validated by an experienced pentester. This removes false positives and frees our specialists to focus on complex, high-impact exploitation that automated tools miss.

Can you test OT and industrial systems without disrupting production?

Yes. We tailor OT/ICS testing to your environment — using passive techniques, agreed maintenance windows and lab replicas where needed — and align our approach to IEC 62443 to protect availability and safety.

Do you cover both IT and OT environments?

Yes. One team covers enterprise IT (web, API, cloud, infrastructure) and operational technology (industrial/ICS), so you get consistent coverage, comparable reporting and a single point of contact.

Which standards and regulations do you support?

Our work supports readiness for ISO 27001, IEC 62443, the OWASP Top 10 and API Security Top 10, and the EU Cyber Resilience Act (CRA), among other frameworks relevant to your industry.
