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.
Core Competencies
- Passive OT/ICS/BAS security assessment — asset inventory, vulnerability findings, and segmentation analysis via the receive-only Sentinel Edge™ platform
- Facility-Related Control Systems (FRCS) cybersecurity engineering: UFC 4-010-06 / UFGS 25 05 11 submittals, documentation, and cyber commissioning support
- Fire alarm and mass notification system cybersecurity (UFC 4-021-01) — state fire alarm licensure on staff
- 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
- Continuous monitoring / ISCM telemetry and SIEM engineering (Zeek, Suricata, Wazuh sovereign stack)
- 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 — zero operational risk to control systems; we never pentest live infrastructure
- Pre-built federal authorization packet (NIST SP 800-53 CA-9 documentation) ships with every OT engagement
- Sovereign analysis — on-premises, no public cloud, no third-party telemetry
- We built and operate our own NIST SP 800-171-aligned enclave before advising anyone else
