Trust is an
engineering artifact.

We build and harden infrastructure for regulated and mission-critical organizations — then prove the posture it claims, with controls an authorizing official can inspect.

Practice areas

Five practices.
One standard of assurance.

Each practice is mapped to the NIST SP 800-53 control families it strengthens — because that's how our clients' obligations are written, and how our work gets measured.

01

Secure Infrastructure Modernization

Design, hardening, and migration of enterprise virtualization and storage platforms to current security baselines for federal and federal-adjacent environments.

  • Trust regulation & management
  • STIG alignment
  • Segmentation
  • NIST: CM · SC · AC
02

Security Engineering & Architecture

Architecture reviews, trust regulation and enforcement design, and continuous posture monitoring — instrumentation mapped to formal security models, grounded in doctoral-level research.

  • Architecture review
  • Trust enforcement
  • Continuous monitoring
  • NIST: PL · SA · CA-7
03

Compliance & Risk Alignment

Gap assessment and remediation against federal frameworks, with authorization artifacts your assessors and authorizing officials can actually defend.

  • NIST 800-53 / 800-171
  • CMMC readiness
  • RMF & ATO support
  • NIST: RA · CA · PM
04

Secure & Sovereign AI Deployment

Turnkey on-premises, air-gapped AI inference environments on customer-furnished hardware — for organizations whose data cannot leave the building.

  • Air-gapped inference
  • Supply-chain integrity
  • Runtime attestation
  • NIST: SR · SC · SI
05

Security Tooling Development

Custom security software and pipeline-integrity tooling: AI pipeline trust verification, SOC dashboards, and purpose-built assurance instruments.

  • Go · Rust · Python
  • Pipeline verification
  • SOC dashboards
  • NIST: SI · AU

About U.S. NETSEC

Experience forged in the federal sector.

Founded in 2011 by industry engineers with real-world federal agency experience, U.S. NETSEC has spent fifteen years securing systems that carry real consequence — engineered and verified hands-on, not advised from slideware.

Our personnel hold CISSP and CEH credentials and advanced degrees, with more than a decade supporting high-security government environments. Every engagement produces artifacts a security officer can defend: documented baselines, traceable controls, and monitoring that proves the posture it claims.
