Defense and Space Manufacturing Sterling, Virginia 201–500 employees Privately Held

Core One provides analytical, operational, and technical solutions to U.S. defense and intelligence agencies. The tech stack reveals a security-first architecture: forensics tools (EnCase, IDA Pro, Binary Ninja, WinDbg), threat intelligence platforms (Palantir, Dataminr), vulnerability scanning (Nessus, Tenable.sc), and virtualization for sandboxed analysis (VMware, ESXi, VirtualBox). Hiring is security-dominated (46 of 122 roles), with 74 senior-level positions — indicating mature client relationships and complex compliance-driven work rather than product scaling.
