IT Services and IT Consulting Huntsville, Alabama 51–200 employees Founded 2010 Privately Held

OASYS is a defense-focused technology services firm built around compliance automation (RMF/ATO packages, SIEM, MITRE ATT&CK) and Microsoft 365 data security (Purview, sensitivity labeling, DLP). The tech stack skews toward systems engineering (C, C++, VxWorks, Enterprise Architect) paired with growing data governance adoption (BigID, Purview, Microsoft Graph API), reflecting a shift from traditional DoD systems work into cloud data protection — a gap many prime contractors haven't closed.
