IT Services and IT Consulting Fredericksburg, VA 201–500 employees Founded 2000 Privately Held

SimVentions is a 201–500-person defense contractor built around cyber security, modeling & simulation, and embedded systems. The stack—Metasploit, Cobalt Strike, MITRE ATT&CK, Kali Linux, plus lower-level languages (Rust, C++, Assembly)—reflects a heavy offensive/defensive security posture. Active projects span tactical weapon control systems, FedRAMP/FISMA accreditation pipelines, and firmware development, while pain points cluster around DoD compliance, system hardening, and rapid iteration within strict regulatory gates. Hiring skews senior (14 of 27 tracked roles), consistent with the specialized, clearance-dependent work.
