Defence Forces - Air-Gapped Secure Communication
Modern defence operations depend on communication that cannot be intercepted, decoded, or attributed. Sanket delivers Signal Protocol end-to-end encryption, air-gap deployment capability, zero-knowledge server architecture, and hierarchical access controls purpose-built for defence organisations where communication compromise represents a direct national security risk.
Sector Risk Indicators
Sanket closes all four vectors with zero-knowledge encryption, sovereign deployment, and admin governance.
The Communication Problem
Why Industry communication is uniquely high-risk
Unresolved risks
Air-gap deployable: entire platform runs within classified network with zero dependency on public internet or foreign cloud
Signal Protocol end-to-end encryption with Perfect Forward Secrecy - each session uses unique ephemeral keys
Zero-knowledge server: your infrastructure stores only ciphertext, never decrypted operational content or metadata
Hierarchical access controls enforce unit, rank, and clearance-level boundaries across all channels
Sanket closes the gap
Command-to-field messaging with priority broadcast, mandatory read acknowledgement, and group coordination
Offline message queueing for operations in signal-degraded or tactically constrained environments
Integration with existing classified identity management, internal certificate authorities, and directory services
Privacy Architecture
In defence contexts, communication metadata is as operationally sensitive as message content. Unit composition, message timing, and coordination patterns can reveal mission intent to sophisticated adversaries. Sanket's zero-knowledge architecture ensures that even the platform operator cannot access metadata that could expose operational structure, command hierarchy, or mission timing.
Security Model
Sanket.Enterprise deploys entirely within a classified or air-gapped environment with no runtime dependency on public internet, foreign cloud, or external certificate authorities. Signal Protocol with Perfect Forward Secrecy means compromising one session key cannot decrypt past or future communications - a property essential for defence-grade operational security.
Deployment Path
Defence organisations deploy Sanket.Enterprise on classified infrastructure - on-premise data centre, isolated network segment, or air-gapped operational site. Custom internal certificate authorities, classified directory integration, and air-gapped update procedures are designed for the most demanding defence deployment environments.
Sanket standard
What every deployment delivers
Defence ministries, military commands, field operations units, intelligence agencies, national security departments, and defence contractors operating under strict operational security mandates.
Air-gapped on-premise deployment - zero foreign internet dependency
Signal Protocol with Perfect Forward Secrecy
Zero-knowledge server - no plaintext stored or accessible
No foreign cloud, analytics, or certificate authority required
Deployment outcomes
What organisations in defence-grade encrypted communication for military operations achieve
Eliminate operational security risk from consumer apps and unmanaged communication channels on defence networks by replacing them with a sovereign, air-gapped platform
Give commanders a reliable encrypted coordination layer with hierarchy enforcement, priority broadcast, and acknowledgement tracking - operable independently of public internet infrastructure
Achieve SIGINT hardening objectives with a zero-knowledge architecture where plaintext never transits or rests outside the sender's device
Can Sanket.Enterprise operate in a fully air-gapped environment with no internet access?
Yes. Sanket.Enterprise is designed with zero runtime dependency on public internet, foreign cloud services, or external certificate authorities. The entire platform - server, key management, identity, and update mechanisms - runs within your classified or air-gapped network.
How does Signal Protocol protect defence communications against interception?
Signal Protocol uses Double Ratchet key derivation with Perfect Forward Secrecy. Each session generates unique ephemeral keys. Even if a future session key is compromised, past sessions remain cryptographically protected - a property essential for operational security against persistent adversaries.
Can Sanket enforce hierarchical military structure in access controls?
Yes. Administrators provision users by unit, rank, and clearance level. Channel access is restricted to verified identities. There is no self-registration, no consumer-style account recovery, and no open-access endpoint that could bypass rank and clearance controls.
Does Sanket have any foreign infrastructure dependencies in its air-gapped deployment?
None. Sanket.Enterprise has no runtime call to external servers, no foreign CDN, no cloud key management, and no external certificate authority dependency. All cryptographic operations run within your deployment environment.
How does Sanket support field operations with intermittent or no connectivity?
Sanket queues messages securely and delivers them on reconnection. The mobile-first design is tested for variable network conditions including the tactical environments common in field operations.
