Connected Systems
Secured by CliffGuard
🏭🔌Secure Industrial Control. Protect Connected Devices. Reduce Physical Risk.
OT, ICS, and IoT environments connect PLCs, HMIs, SCADA platforms, sensors, embedded devices, industrial protocols, cloud services, and enterprise networks. Weak segmentation, insecure firmware, exposed engineering interfaces, and unauthenticated commands can disrupt production, alter physical processes, or compromise safety.
CliffGuard’s OT/ICS & IoT Security Testing Services assess industrial systems and connected-device ecosystems from the network layer to the device hardware. Our safety-first methodology combines passive analysis, protocol testing, firmware review, hardware-interface assessment, and controlled exploitation without unnecessarily disrupting operations.
🏭🔌 🎯 What is OT/ICS & IoT Security Testing?
OT/ICS Security Testing evaluates industrial control systems, operational networks, engineering workstations, controllers, supervisory systems, remote-access paths, and supporting infrastructure for exploitable weaknesses.
IoT Security Testing assesses connected devices, embedded software, firmware, communication protocols, mobile applications, cloud services, APIs, and device-management platforms across the complete product ecosystem.
CliffGuard applies safety-conscious testing, passive discovery, manual validation, and controlled exploitation to identify genuine attack paths while respecting operational availability, production constraints, and approved testing boundaries.

OT/ICS and IoT Security Testing Lifecycle
From Asset Profiling to Safe Exploitation—Validating Every Cyber-Physical Path
Our Process
Define critical processes, equipment dependencies, authorized assets, prohibited actions, maintenance windows, recovery procedures, and operational contacts. Establish clear rules of engagement for safe testing.
Passively identify controllers, HMIs, engineering stations, IoT devices, protocols, firmware versions, network relationships, remote-access services, and external communication paths.
Review segmentation, protocol behavior, device identity, firmware components, hardware interfaces, cloud integrations, cryptographic controls, update mechanisms, and administrative trust relationships.
Validate approved weaknesses in laboratory, staging, maintenance-window, or carefully controlled production conditions. Test unauthorized commands, access bypass, firmware flaws, exposed interfaces, and device-control pathways.
Deliver technical evidence, operational impact, risk ratings, compensating controls, and prioritized remediation guidance. Retest corrected weaknesses to confirm security improvement without affecting reliability.

❓ Frequently Asked Questions (FAQs)
Depending on the authorized environment, testing may cover Modbus/TCP, DNP3, OPC UA, IEC 60870-5-104, EtherNet/IP, PROFINET, MQTT, and other proprietary or industry-specific protocols.
Yes. Testing can include firmware extraction, binary analysis, hardcoded-secret discovery, update validation, secure-boot review, and assessment of UART, JTAG, SWD, storage, and debug interfaces.
Yes, when authorized and operationally appropriate. We prioritize passive techniques and restrict active validation to approved assets, laboratory systems, maintenance windows, or carefully controlled production conditions.
We assess firewalls, industrial DMZs, jump servers, VPNs, Active Directory relationships, vendor access, cloud connections, and other pathways that could enable movement into OT environments.
Testing may cover the physical device, firmware, operating system, wireless communication, mobile application, web portal, backend APIs, cloud platform, identity controls, and update infrastructure.
Assessments may align with IEC 62443, NIST SP 800-82, NIST CSF, MITRE ATT&CK for ICS, OWASP IoT guidance, ETSI IoT security principles, and ISO 27001.
