Sentinel Dynamics LTD is a service-disabled-veteran-owned OT/ICS cybersecurity and resilience advisory firm. Risk and resilience work grounded in three decades on every side of the systems we secure — manufacturing, healthcare, higher education, state government, and defense — delivered by the founder who quotes the work. Assessment and advisory only: we never install, configure, program, or repair client systems.
Core Competencies
- Passive OT/ICS/SCADA/BAS security assessment — asset inventory, vulnerability findings, and segmentation analysis via the receive-only Sentinel Edge™ collector, connected by the client's staff
- ORC 9.64 and AWIA cybersecurity for Ohio local governments and water systems — plants, lift stations, and SCADA
- Facility-Related Control Systems (FRCS) cybersecurity: UFC 4-010-06 / UFGS 25 05 11 submittal and documentation support
- CMMC 2.0 Level 1/2 and NIST SP 800-171 readiness: gap analysis, SSP and POA&M development, SPRS scoring support for defense suppliers
- Protocol-level analysis of captured OT traffic on our own sovereign stack (Zeek, Suricata)
- RMF assessment-and-authorization support — eMASS package inputs and CA-9 connection documentation
Differentiators
- Founder-operator — the person who scopes the engagement performs it
- Tradesman + cyber: Ohio Journeyman Electrician and Fire Alarm License behind a CISSP/CCSP credential stack — fluent on the jobsite and in eMASS
- Receive-only methodology: the capture interface carries no IP and cannot transmit; no active scanning and no security testing of client systems
- Pre-built federal authorization packet (NIST SP 800-53 CA-9 documentation) ships with every OT engagement
- Sovereign analysis — on our own hardware, no public cloud, no third-party telemetry
- We built and operate our own NIST SP 800-171-aligned enclave before advising anyone else
