Visibility
Without
Vulnerability.
Fix What
Matters First.
Sentinel Dynamics provides independent risk and resilience advisory for industrial operators. We map your OT, ICS, SCADA, and building automation systems — without active scanning or downtime — and deliver a clear, prioritized roadmap to reduce your operational exposure.

Your Systems Weren't
Designed to Be Secure.
They Were Designed to Run.
And they do. Reliably. Continuously. Often for decades. That's a testament to the people who maintain them.
But the environment around those systems has changed. Threat actors now specifically target the invisible layers of control systems and OT — because they know these systems are the backbone of your operations.
Meanwhile, auditors and insurance carriers are asking technical questions that your team — already stretched thin — was never meant to answer.
sense that risk exists.
Getting a clear picture
of where it lives
is the harder problem.
Most teams don't have an OT security architect on staff — and they shouldn't need one. Generic assessments often produce a long list of findings with no guidance on what matters and no one left to help execute. That's not what we do.
NERC CIP, NIST CSF, IEC 62443, and CMMC are no longer optional. Documentation gaps aren't just technical debts — they are financial liabilities at audit time.
Carriers are no longer checking boxes — they're scrutinizing OT connectivity. Without evidence-based answers at renewal, you're facing premium spikes or outright exclusions.
Your IT tools stop at the carpet's edge. Your integrator left years ago. That gap often stays invisible until a compliance review surfaces it — or an incident makes it obvious. That's the gap we close.
We Work With What You Have.
We Don't Add Complexity
to Fix Complexity.
Sentinel Dynamics acts as your Resilience Broker — an independent advisor sitting between your technical environment and the critical decisions you need to make about it. We collect, analyze, and prioritize. We don't force hardware upgrades, take over your network, or disrupt live operations. What we deliver is clarity: a documented, defensible roadmap of your actual risk, ranked by operational impact.
We start with your existing environment: network captures, device inventories, BAS exports, and integrator documentation. No new sensors required. No production changes. No downtime.
Our proprietary analysis engine maps hidden attack paths, identifies segmentation gaps, and flags unmanaged devices — cross-referencing every finding against the compliance frameworks that matter to your auditors.
Not every finding is a crisis. We filter the noise to rank risks by operational impact and ease of remediation. You get a mitigation sequence you can execute — not a spreadsheet of 200 "Critical" alerts.
You receive two distinct deliverables: a Technical Action Plan for your engineers and a Defensible Executive Summary for leadership, auditors, and insurance carriers. No jargon. Just clear, actionable intelligence.
We Work With the People
Who Keep Equipment Running.
Our clients aren't enterprise security teams with dedicated OT analysts. They are facility managers, plant engineers, utilities directors, and operations leads who carry real-world responsibility for systems that cannot go down — and who are now being asked to prove those systems are secure.
Aging SCADA, PLCs, and RTUs under SDWA §1433 risk assessment and emergency response plan requirements, with limited internal security resources.
BAS exposure, HIPAA-in-scope OT, and networked PACS controllers — badge reader and access control systems are classified as OT under NIST SP 800-82r3 and are in scope for CMMC where they touch the covered environment.
OT/IT convergence and aging infrastructure with NERC CIP-adjacent requirements and limited monitoring visibility.
Closing the Integrator Gap across multi-site BAS and complex HVAC, lighting, and access control networks — including PACS controllers most teams don't realize are in scope.
Mixed IT/OT environments with vanished integrators, insurance gaps, and CMMC supply-chain obligations.
BAS-heavy facilities with no security documentation, thin IT staff, and growing state compliance unknowns.
GSA buildings, military installations, and DIB contractors pursuing CMMC Level 2 certification face OT and PACS scoping requirements that most assessors flag. We're SDVOSB set-aside eligible and built for sovereign, air-gap environments where cloud-connected tools are prohibited.
Start Where You Are.
Go as Deep as You Need.
Every engagement begins with a conversation about your environment — not a product pitch. Our tiers are designed to meet operators at their current level of risk awareness, not where a vendor's quota needs them to be.
Review
- Guided WalkdownPanels, network closets, engineering workstations, remote access hardware, and the boundary where your office network meets your plant network.
- Structured InterviewMaintenance, IT, safety, and the integrator relationships nobody has mapped. Every answer of “I do not know” is recorded as a finding, because it is one.
- Ownership MapWho owns each path into your control systems, and who owns each recurring task on them. This is the gap most operators discover they have.
- Written FindingsPrioritized by operational impact and mapped to CISA Cross-Sector Cybersecurity Performance Goals and NIST SP 800-82r3.
- Executive SummaryOne page for leadership, auditors, and carriers.
No device connected to your network. Nothing scanned. Nothing touched. Stands alone, or becomes the scoping step for a Tier 1 baseline.
Exposure Assessment
- Everything in Tier 0, InstrumentedThe walkdown and interview, plus a monitored capture window on your network.
- Complete Asset InventoryEvery PLC, controller, and gateway on your wire — visible, mapped, and documented.
- Network Risk MapA visual model of exactly how a threat could move through your BAS or OT environment.
- Prioritized RemediationA sequenced action plan ranked by operational impact — not just CVSS scores.
- Executive & Technical ReportsJargon-free documentation for the Board, the shop floor, and the insurance carrier.
Onsite or remote. Typical turnaround: 2–3 weeks.
Resilience Review
- Drift DetectionIdentify new devices or unauthorized changes since your last baseline.
- New Exposure AnalysisDeep-dive on emerging threats specific to your hardware stack.
- Patch & Segmentation AdvisoryExpert guidance on which updates are safe — and critical — to apply.
- Insurance Impact SummaryFresh evidence for your carrier to maintain coverage and lower premiums.
- Updated RoadmapA living mitigation document that evolves as your facility grows.
Scheduled quarterly. Builds on your Tier 1 baseline.
Intelligent Overlay
- Continuous Network AwarenessPassive ICS/OT/BAS protocol monitoring via NDAA Section 889 compliant edge sensors — persistent visibility without agents, inline hardware, or production impact.
- Cyber Anomaly Review (in development)Behavioral deviations reviewed against a rolling baseline and mapped to CMMC and IEC 62443 controls. Automated scoring is on the roadmap; today the analysis is ours, not a black box.
- Equipment Fault Detection (in development)The same protocol visibility that surfaces cyber exposure also sees operational behavior: polling irregularities, controller fault signatures, drive behavior. We are building that into the platform as a reliability capability, with optional thermal, vibration, and acoustic sensing for rotating equipment. If that is interesting to your operation, tell us. Early input shapes what ships.
- Rhythm of the PlantCollected continuously and processed centrally, so normal operating rhythm becomes a known quantity and departures from it stand out. A plant that has never been baselined has nothing to compare an incident against.
- Monthly Resilience ScoringTrend reports that show directional improvement in security posture — defensible for auditors and insurance carriers.
- Priority Advisory AccessOn-call expertise for when your team encounters something they can't answer.
For operators who need continuous intelligence without a full-time security team.
Advisory
- NIST SP 800-171 Gap AnalysisA structured review of your current posture against all 110 practices — with honest scoring, not box-checking.
- System Boundary DefinitionThe scoping step most small contractors fail. We define what's in scope before an assessor does it for you.
- OT & PACS ScopingPhysical access control systems fall under the Specialized Asset categories in 32 CFR §170.19, and they are routinely missed in scoping. We document them correctly so your C3PAO doesn't find the gap first.
- SSP & POA&M DevelopmentReady-to-submit documentation your team can act on and your assessor can verify.
- Remediation RoadmapPrioritized by what an assessor will look for first — not alphabetical order.
SDVOSB set-aside eligible. Sovereign analysis — no data leaves your environment.
Sentinel Dynamics' practice is expanding into adjacent risk disciplines — cyber risk quantification (FAIR), business continuity & resilience, and AI governance — as those credentials mature.
Purpose-Built Tools.
Not Repurposed
Enterprise Software.
Our assessments run on instrumentation built for these environments. Sentinel Edge is the field-deployed node that collects the data behind every engagement — backed by a sovereign, on-premises analysis stack. Purpose-built, NDAA Section 889 compliant, and operated by Sentinel Dynamics, not third-party tools we resell.
Sentinel Edge is the passive, NDAA Section 889 compliant node we deploy on your network via SPAN port or TAP to gather the data behind an engagement. It parses ICS protocols from the mirrored traffic, so an engagement works from what your equipment actually says rather than from a vendor list or a drawing. On-board behavioral baselining and deviation scoring are in development. No active probing. Zero production impact. No data leaves your premises. Everything it captures feeds the prioritized assessment and reports you receive.
Collected data is triaged and turned into compliance-mapped findings and executive-ready reports on dedicated local compute — no cloud, no third-party telemetry, no data egress.
Authorized attack-path validation for OT, ICS, and SCADA environments. Run against lab replicas, test cells, or planned maintenance windows, never against a running process. Proof that detection and response work, on top of the assessment that finds what to fix.
Encrypted CUI evidence handling and CMMC artifact management for DIB and federal engagements, on FIPS-validated, air-gap-capable foundations.
We're Not a Vendor.
We're Not a SOC.
We're Your Advisor.
We sit between what is technically true about your environment and the decisions you need to make about it. That's a different kind of relationship — and a different kind of accountability.
Our analysis is grounded in how OT and BAS systems actually operate — not how IT security frameworks assume they should. We parse BACnet/IP & MSTP, Modbus TCP, EtherNet/IP, DNP3, PROFINET, S7comm, OPC-UA, KNX/IP, LonWorks, EtherCAT, and PACS IP traffic. You won't spend the first hour explaining what a serial gateway is to us.
Our assessments are passive. We work from existing data, logs, and mirrored traffic. No agents. No inline sensors. No changes to production. If it’s running, we don’t touch it. Anything active is a separate, scheduled engagement you authorize in advance, and it never runs against a live process.
A solo, veteran-owned practice led by a cybersecurity and industrial-controls professional — not a rotating bench of generalists. SDVOSB · VOSB · Ohio VFBE certified. The person who reads your ladder logic is the same person who writes your report.
Our analysis devices operate on-premise. No cloud dependencies. No third-party telemetry. Analysis runs in a sovereign, secure environment. Air-gap capable. Your sensitive network data never touches public infrastructure — critical for NERC CIP, HIPAA, CMMC, and DFARS environments.
Every engagement ends with defensible documentation for the Board, the Auditor, and the Insurance Carrier. No 200-item spreadsheet sorted by CVSS. You get a Technical Action Plan prioritized by operational impact and what you can actually fix with your current staffing.
Traditional IT security stops at the carpet's edge. Most OT vendors don't understand compliance frameworks. We sit at that exact intersection. If your IT team has ever said "that's not our problem" about your BAS or control network — we are the answer to that sentence.
The Field and the Framework —
in One Operator.
Sentinel Dynamics is a solo, veteran-owned practice built on a background most cyber consultants don't have: hands-on industrial controls work. Years in the field as a journeyman electrician — pulling conductors, reading ladder logic, commissioning fire and building-automation panels — before moving into enterprise cybersecurity and compliance.
That path is the differentiator. Most OT assessments are run by IT-security generalists who have never opened a control cabinet. Most controls engineers have never written a System Security Plan. This practice sits at that exact intersection.
The result: assessments grounded in how your equipment actually runs, and documentation that traces cleanly to the frameworks your auditors and contracting officers use.
Don't Wait for
the Audit.
Don't Wait for
the Incident.
Every resilient operation starts with a single conversation about what's actually at risk. Let's identify your exposure before it becomes an operational reality. No pitch. No pressure. Just a focused 20-minute conversation about your environment.
