OT/ICS Cybersecurity

Protect the systems that physical operations depend on.

OT and ICS environments run by different rules than IT. Availability and safety come first, and a misconfigured sensor can be as dangerous as a breach. We secure industrial control systems without disrupting the operations they run.

Caplock Security brings deep expertise in ICS protocols, SCADA architectures, and the federal standards that govern these environments, so enterprises can protect critical assets without compromising uptime.

Protecting the mission and the machinery.

What we do

  • Asset Discovery & Inventory

    Map every device across legacy and modern control environments.

  • Network Segmentation

    Isolate OT from IT without breaking operational continuity.

  • Protocol-Aware Monitoring

    Detect threats across Modbus, DNP3, EtherNet/IP, and OPC-UA.

  • Vulnerability Assessment

    Prioritize risk without taking systems offline.

  • Incident Response Planning

    OT-specific playbooks, tabletops, and recovery procedures.

  • Compliance Alignment

    Map controls to NIST SP 800-82, ICS-CERT guidance, and CMMC.
