Open Systems Technologies builds security architectures and systems integration solutions for large federal and enterprise customers. The stack reveals a heavy focus on identity and access management (SailPoint IdentityIQ/IdentityNow, IBM Security Verify, Saviynt) paired with security operations infrastructure (Splunk Enterprise Security, Cribl, Azure Sentinel, Kali), indicating mature SIEM and IAM modernization work. Hiring is heavily weighted toward security and engineering roles at senior levels, matching active projects around DoD identity systems and FBI infrastructure—a profile of deep enterprise security delivery rather than product development.
