Tenet3 delivers cybersecurity for DoD-scale cyber-physical systems, combining zero-day vulnerability detection, microelectronics inspections, and quantitative risk assessments using model-based system engineering (MBSE). Its MeTRA platform creates digital twins and digital threads across a system’s lifecycle to identify vulnerabilities and guide security investments, while MeTRA-HUB provides IL5 cloud hosting and BOMSquad analyzes SBOMs to spot risky C/C++ code. The company differentiates itself with defense-domain expertise, lifecycle-spanning digital models, and a closed-loop MBSE approach tailored to quantify risk and optimize security choices, rather than offering generic tools. Its goal is to harden critical defense infrastructure by delivering measurable risk reduction and strong support for Zero Trust architectures across hardware, software, and processes, under federal contracts and SBIR/IDIQ programs.

Simplify's Take

What believers are saying

  • A 2026 Air Force modification added $3.36M, extending anti-tamper work through December 2026.
  • HigherGov tracks $74.1M backlog on the Masters SBIR Phase III vehicle.
  • LinkedIn and Greenhouse postings in 2026 signal active hiring across engineering roles.

What critics are saying

  • Tenet3 depends heavily on Air Force and AFRL funding, concentrated through 2026.
  • HigherGov shows only 44 employees, limiting delivery capacity against larger defense primes.
  • If the 2022 SBIR Phase III ends without follow-on awards, revenue resets sharply.

What makes Tenet3 unique

  • MeTRA®HUB holds AFRL approval for IL5 CUI and ITAR on AWS GovCloud.
  • Tenet3 combines MBSE, digital twins, and anti-tamper engineering for cyber-physical systems.
  • Its 2022 Masters SBIR Phase III created long-tail sole-source access at AFSC.
