While not strictly required for CMMC, GCC High is often the most practical solution for organizations seeking to achieve CMMC Level 2 compliance or above, especially if they process or store export-controlled information. **GCC High Key Benefits:** - **Data Sovereignty:** U.S.-only data storage and access, restricted to screened U.S. personnel. - **Regulatory Alignment:** Meets DoD SRG, FedRAMP High, ITAR, NIST 800-171 and DFARS requirements. - **Secure Collaboration**: Provides Microsoft Teams, Exchange, and SharePoint in a compliant cloud. - **Integration:** Seamlessly connects with Microsoft Defender, Intune, and Purview for data governance. **How We Help:** Daymark is a Microsoft AOS-G Licensing Partner for Microsoft 365 GCC, High GCC and Azure Government. As part of the CMMC ecosystem, we are also a member of the CYBER AB (Formerly CMMC-AB) as a (RPO) Registered Provider Organization. ![CMMC-300x300](https://www.daymarksi.com/hs-fs/hubfs/CMMC-300x300.png?width=225&height=225&name=CMMC-300x300.png) ![Gov-cert-1](https://www.daymarksi.com/hs-fs/hubfs/a-site-images/government/Gov-cert-1.png?width=419&height=175&name=Gov-cert-1.png) ![Gov-cert-2](https://www.daymarksi.com/hs-fs/hubfs/a-site-images/government/Gov-cert-2.png?width=421&height=176&name=Gov-cert-2.png) ![cmmc-AB-CISSP](https://www.daymarksi.com/hs-fs/hubfs/a-site-images/government/cmmc-AB-CISSP.png?width=424&height=247&name=cmmc-AB-CISSP.png) ### Contact us Today about Microsoft 365 GCC High ** ### First Pain Point This should be the biggest pain your clients have as it relates to your service.
