Government Agency Deploys Air-Gapped Sanket.Enterprise for Classified Communication

A government agency responsible for national security-adjacent operations required a secure communication platform that could function entirely within classified network infrastructure - no public internet dependency, no foreign cloud services, no external certificate authorities, and full operational sovereignty over every component. Tosh Defence Private Limited engaged through a formal procurement process to plan and deploy Sanket.Enterprise within the agency's air-gapped environment.
