Chromalox
Administration and security governance across a global multi-company environment using Microsoft 365, Entra ID, Conditional Access, compliance documentation, and audit evidence workflows.
- Challenge
- Keep identity, access, and compliance operations consistent across a global multi-company Microsoft environment spanning approximately 1,600+ users, more than 30 countries, and 100+ locations.
- Approach
- Administer Microsoft 365 and Entra ID with Conditional Access and Protected Access policies, then operationalize CMMC Level 2 readiness through Azure Government work, SSP documentation, evidence collection, and assessor coordination.
- Impact
- Access-control and compliance work stays tied to how the environment actually runs—identity policy, documentation, and audit evidence instead of a parallel paper program.
- Scale
- Approximately 1,600+ users, multiple companies and divisions, more than 30 countries, and 100+ locations.
