Welcome To SombraSec Strategies
SombraSec Strategies LLC is a Service-Disabled Veteran-Owned Small Business (SDVOSB) focused on nuclear security consulting and licensing, inspection readiness, and security support for the next generation of nuclear deployment. We help advanced reactor, small modular reactor (SMR), microreactor, uranium enrichment, and source material developers move from concept to licensing, construction, and operations with practical, defensible, inspection-ready security program plans and procedures.
Led by a former Director of DOE Safeguards & Security and NRC nuclear security inspector, SombraSec brings a rare combination of federal program leadership, regulator-side inspection experience, and hands-on nuclear security execution. Our support includes NRC security licensing, DOE Safeguards and Security (S&S), DOE-STD-1271-2025 demonstration and pilot reactor projects, industrial security, Facility Clearance (FCL), Foreign Ownership, Control, or Influence (FOCI) mitigation, national security site protection, vulnerability assessments, physical protection strategies, corrective action planning, and compliance documentation that regulators, federal reviewers, investors, and project teams can understand and defend.
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
Nuclear Security built around your operations, cost, and schedule—not forced compliance.
Less rework. More progress.
