Millennium Tech Stack

DoD-focused cybersecurity and red team operations

Information Technology & Services Arlington, VA 201–500 employees Founded 2004 Privately Held

Millennium is a DoD-contracted cybersecurity firm built around offensive and defensive operations, with 300+ staff split heavily toward senior security roles (8 of 17 current openings). The stack reflects dual concerns: adversarial tooling (Metasploit, Cobalt Strike, Burp Suite, Bloodhound) for red team work, plus enterprise infrastructure (VMware, NetApp, SAP, Oracle, Deltek) for customer deployments and program management. Active hiring acceleration in security and engineering, combined with projects spanning penetration testing, exploitation research, and cloud connectivity, suggests scaling existing contracts rather than platform pivots.
