About Blue Heron InfoTech

Blue Heron InfoTech provides modern IT infrastructure solutions for manufacturers and growing businesses. We specialize in private cloud platforms, Linux infrastructure, identity management, cybersecurity, virtualization, backup and disaster recovery, and business collaboration systems.
