What we do
Verasor delivers Microsoft 365 consulting and licensing across commercial, government, and DIB customers, with a specialized practice in CMMC readiness, GCC High, and the regulatory work that comes with handling CUI.
M365 implementation, configuration, and licensing for commercial, government, and DIB customers. Tenant licensing strategy, identity, productivity, and security posture, based in Microsoft best practice.
Gap assessments against NIST SP 800-171(a) r2, control implementation, System Security Plan authoring, and POA&M management. Audit-ready evidence packages, not checkbox slideshows.
Tenant strategy, content migration, identity cutover, and hardening for Microsoft 365 GCC High. Built around CUI handling, DFARS 252.204-7012, and the operational realities of small DIB shops.
Entra ID, Conditional Access, Intune, and Purview DLP configured to enforce the controls your assessor will look for. Day-to-day operations and ongoing posture management.
Fractional security leadership for organizations that need senior judgment without a full-time CISO. Policy authoring, incident response readiness, and a steady hand through audits.
Verasor does Microsoft 365 well, and we do CMMC and GCC High exceptionally well. If your work involves CUI, DFARS 252.204-7012, or a CMMC deadline tied to a DoD prime, that is the room we live in. If you need a managed helpdesk or a network installer, that is not us.

What DFARS 252.204-7012 actually requires of defense contractors. NIST 800-171, 72-hour incident reporting, subcontractor flow-down, and cloud authorization.
When defense contractors should migrate to Microsoft 365 GCC High and when commercial M365 is still defensible.
We will give you a straight read on where you stand, what it will take to close the gap, and how long that work realistically runs.
