Government contractors and subcontractors should use the file sharing solution that meets their individual needs and requirements. Department of Defense (DoD) contractors and subcontractors must, however, ensure their chosen solution is compliant with the Cybersecurity Maturity Model Certification (CMMC) requirements. Federal Risk and Authorization Management Program (FedRAMP) authorization may also be required. Compliance typically involves using a file sharing solution that has appropriate security controls, such as encryption and access controls, to protect against cyber threats and safeguard sensitive information.
