SOSi Tech Stack

Mission-critical tech and services for defense, aerospace, and government

Defense and Space Manufacturing Reston, Virginia 1,001–5,000 employees Founded 1989 Privately Held

SOSi operates deep in the defense and government services stack — Cisco, Palo Alto, VMware, Azure, Kubernetes across mission-critical infrastructure. The hiring mix (security and engineering bulk, with support teams running 24/7) and active projects (zero-trust, cloud security guardrails, DHS cybersecurity program integration) signal an organization managing high-compliance, always-on systems for federal clients. Pain points around continuous monitoring, Section 508 compliance, and legacy logging modernization show the tension between supporting operational continuity and upgrading aging infrastructure.
