What Is Microsoft GCC High—and Who Needs It?

Microsoft 365 GCC High is a secure cloud environment designed for U.S. government agencies and contractors that must meet strict compliance standards such as CMMC, DFARS, ITAR, and FedRAMP High. Unlike commercial Microsoft 365 or standard GCC, GCC High meets stringent cybersecurity and data sovereignty requirements—and is hosted in dedicated, U.S.-only infrastructure.

GCC High is ideal for:

  • Defense contractors (DoD supply chain)
  • Aerospace and manufacturing firms
  • Federal agencies and partners
  • Companies subject to ITAR, NIST 800-171, or CMMC
