Click an attack button and watch how a real OT attack compromises the process control system – from first detection to critical alarm.
Many PLCs and RTUs have no authentication and are directly reachable on the network – an ideal entry point for attackers.
Growing interconnection between IT and OT creates bridges that lead attackers from the office network into production – often undetected.
Industrial systems often run for 15–30 years. Patches are rare, and known CVEs remain open and actively exploited.
Modbus, DNP3, Profibus – industrial protocols were never designed with security in mind. No encryption, no authentication.
Colonial Pipeline, Norsk Hydro – ransomware shuts down production and costs millions per hour of downtime.
Tampered firmware, compromised maintenance access, and infected software updates open hidden backdoors into your systems.
Authentication, firmware, programming ports, and unauthorized commands on Siemens S7, Rockwell, Schneider, ABB & more.
Web interfaces, OPC servers, historian databases, and remote access tested for known vulnerabilities.
IT/OT zoning, DMZ configuration, firewall rules, and unauthorized crossover connections exposed.
Modbus, DNP3, IEC 60870, Profinet, OPC UA – sniffing, replay, and manipulation under controlled conditions.
VPN, remote maintenance access, jump servers, and DMZ architectures tested for vulnerabilities and misconfigurations.
WiFi in production environments, Bluetooth sensors, LoRaWAN, and rogue access points identified.
Extraction, analysis, and fuzzing of embedded firmware for insecure implementations and backdoors.
Audit-ready reports for KRITIS, NIS2, IEC 62443, BSI IT-Grundschutz, and ISO 27001.
OT security is a regulatory obligation for critical infrastructure operators and industrial companies. We deliver audit-ready evidence.
Critical infrastructure operators are required under §8a BSIG to demonstrate adequate OT security measures.
The EU directive massively expands the scope of affected companies and mandates technical OT security assessments.
IEC 62443
International standard series for OT/ICS security – the de-facto standard for SCADA and industrial control systems.
Annex A includes explicit requirements for physical and network segmentation of industrial systems.
BSI IT-Grundschutz
The BSI ICS profile provides concrete measures for operators of industrial control systems in Germany.
Extends NIS2 to physical resilience of critical entities – including OT protection measures along the value chain.
No – a professional OT pentest differs fundamentally from IT tests. We start passively (scanning, sniffing) and only conduct active tests in agreed time windows, on isolated components, or in test environments. Every measure is coordinated with your operations team beforehand. Production safety always takes priority over test results.
The most important are IEC 62443 (international OT security standard), BSI IT-Grundschutz (ICS profile), KRITIS Regulation (§8a BSIG), and the NIS2 Directive (EU). Our reporting is aligned with these requirements and delivers audit-ready evidence.
Depending on scope, an OT pentest takes between 3 and 10 days. Typical breakdown: 1–2 days passive reconnaissance, 2–4 days active testing, 1–2 days reporting. For large critical infrastructure we plan staged test schedules across multiple maintenance windows.
Critical findings are escalated immediately (during the test) to your security and operations team. You receive an instant risk assessment and actionable workarounds. The final report contains a complete remediation roadmap prioritized by business impact.
Yes. We work with three approaches: (1) Passive analysis – read-only traffic scanning with no activity in the OT network. (2) Semi-active – scans with very low intervals in agreed time windows. (3) Parallel test environment – identical hardware in your test plant or our OT lab.
We support all major vendors: Siemens S7 (S7comm, S7comm-Plus), Rockwell/Allen-Bradley (EtherNet/IP, CIP), Schneider Electric, ABB, Beckhoff, and others. Protocol coverage includes Modbus TCP/RTU, DNP3, IEC 60870-5-101/104, Profinet, Profibus, OPC UA, OPC Classic, and BACnet.
An OT pentest requires deep knowledge of industrial processes. Availability trumps confidentiality: a production stoppage caused by a failed test can cause more damage than the attack itself. We use OT-specific tooling, understand the limitations of sensitive PLC systems, and coordinate every step with your control room.
Absolutely – that is the gold standard. A full-chain scenario covers the most realistic threat: physical entry, lateral movement through the IT network, pivot into OT, manipulation of the production plant. These combined tests deliver the most valuable insights for your holistic resilience.
