Few Connecticut managed service providers work across construction, education, finance, and government while maintaining HIPAA, CMMC, NIST, PCI DSS, and SOX compliance simultaneously. Citadel Blue, operating from Greenwich for roughly 16 years, navigates this demanding intersection where regulatory rigor and sector diversity converge. The firm handles backup and disaster recovery, cloud migration, and cybersecurity alongside compliance management—work that demands both technical depth and the regulatory fluency most generalists never develop.
