Welcome To SombraSec Strategies
SombraSec Strategies LLC is a Service-Disabled Veteran-Owned Small Business (SDVOSB) specializing in NRC physical security consulting for advanced reactors, small modular reactors (SMR), microreactors, uranium enrichment facilities, and source material licensees. We also provide DOE Safeguards and Security (S&S) program support across the nuclear complex. With decades of DOE and NRC implementation and inspection experience, our experts help developers and contractors build inspection-ready physical security plans, security vulnerability assessments, and regulatory compliance programs under 10 CFR 73, 10 CFR 74, 10 CFR Parts 26, 37, 40, 95 and DOE O 470 series that keep licensing and construction on schedule.
Inspector's Perspective
45+ U.S. commercial nuclear reactors. 17 DOE field sites. 15+ federal facilities. 17+ international reviews.
We’ve seen where programs fail—and how to prevent it.
Licensing That Holds Up
DOE & NRC Safeguards & Security programs built the way regulators actually evaluate them.
Built to pass. Built to defend.
Built Around Your Project
Security built around your operations, cost, and schedule—not forced compliance.
Less rework. More progress.
