Defence Communication Needs a Different Standard
Indian defence communication cannot be treated like normal workplace messaging. Units need rapid coordination, strict identity assurance, and confidence that message content is not exposed to a server operator, foreign vendor, or compromised backend.
Consumer messengers are convenient, but convenience is not the same as operational control. Defence users need encrypted communication that supports controlled onboarding, device trust, audit boundaries, and sovereign deployment options.
What Secure Chat Must Provide
A secure defence chat platform should keep plaintext outside the server. It should support end-to-end encryption, strong device identity, disciplined access control, and resilient operation across public internet and private infrastructure.
For Indian defence contexts, sovereignty matters as much as encryption. Sensitive communication should be deployable on Indian infrastructure and adaptable to classified or restricted networks where foreign runtime dependency is unacceptable.
The Sanket Approach
Sanket is designed around a zero-knowledge server model. The server relays encrypted data and enforces policy, but it should not need access to plaintext messages to function.
That architecture gives defence teams a practical path toward secure communication across field units, command teams, and sensitive departments while preserving ownership of data, deployment, and operational policy.
