Penetration Testing for
the High-Tech Sector

OT (Operational Technology) environments require a specialized approach due to the criticality of production processes. We perform tests without disrupting production, use industrial protocols (Modbus, OPC UA, Profinet), verify PLC/RTU controllers, test physical security measures, and ensure IEC 62443 compliance. Standard IT tests focus on web applications and office networks.

No – we use non-intrusive methodologies or perform tests during maintenance windows. Before starting an audit, we carefully agree on scope, schedule, and emergency procedures. Some tests are performed on test environments or configuration copies. Our team has experience testing 24/7 environments without impacting production.

Red Team tests simulating APT attacks help identify weak points before real attackers do. We verify: network segmentation (R&D isolation from the Internet), DLP (Data Loss Prevention), data exfiltration monitoring, code repository security, access control to CAD/PLM systems, and R&D employee training on targeted phishing and social engineering.

Key standards include: IEC 62443 (ICS/SCADA cybersecurity), ISO 27001 (information security management), NIST 800-82 (ICS security), ISA/IEC 62443 (Industrial Automation Security), NIS2 (Critical Infrastructure), TISAX (automotive industry), and sector-specific standards like DO-178C (aerospace) or IEC 61508 (functional safety). We help achieve compliance with these standards.

Yes – we offer pre-release security audits of IoT/IIoT devices. We test firmware, hardware (JTAG/UART), communication protocols (MQTT, CoAP, BLE), OTA update mechanisms, encryption, authentication, and compliance with ETSI EN 303 645 (Consumer IoT Security). This helps detect vulnerabilities before mass production and avoid costly recalls.

It depends on scope: web application pentest 5-10 days, OT/ICS infrastructure audit 2-4 weeks, Red Team engagement 4-8 weeks, IoT audit 1-2 weeks per device. Supply chain assessment can take 6-12 weeks. We adjust the schedule to the client’s production timeline and maintenance windows.

Yes – high-tech companies falling under NIS2 (key digital service providers, electronics manufacturers, aerospace) must meet risk management, business continuity, and incident reporting requirements. We conduct gap analysis, NIS2-compliant pentests, supply chain risk audits, and help implement CERT/CSIRT procedures.

Top vulnerabilities include: default passwords (admin/admin), lack of communication encryption, outdated firmware without updates, unsecured debug interfaces (JTAG/UART), hardcoded credentials in firmware, lack of OTA update validation, exposed debug ports to the Internet, and vulnerabilities in MQTT/CoAP protocols enabling MITM and replay attacks.

Yes – we provide 24/7 support when critical vulnerabilities (CVSS 9.0+) are discovered. We offer: incident response, remediation assistance, responsible disclosure for zero-day vulnerabilities, vendor coordination, emergency patching guidance, communication with CERT/CSIRT, and retesting after fixes are implemented. We work with the client until the vulnerability is fully resolved.

We perform vendor risk assessments (security questionnaires, on-site audits), SBOM analysis (Software Bill of Materials), open-source library dependency scanning, firmware/chipset integrity verification, supplier build pipeline testing, code signing verification, and threat intelligence monitoring for compromised vendors. In accordance with NIST 800-161 and Executive Order 14028.
