Sanket.Enterprise - Air-Gapped On-Premise Secure Communication
Sanket.Enterprise is built for organisations where the answer to 'where is our communication data?' must be 'inside our own infrastructure, under our own jurisdiction, with no foreign dependency at any layer.' Defence forces, intelligence agencies, government departments, and critical infrastructure operators deploy Sanket.Enterprise when complete infrastructure ownership is non-negotiable.
What this means
The platform, in plain terms
Fully isolated on-premise deployment - entire platform runs inside your data centre or secure network
Air-gap capable: no runtime dependency on public internet, foreign cloud, or external certificate authorities
Custom internal certificate authority and directory integration for fully sovereign identity management
Signal Protocol end-to-end encryption with Perfect Forward Secrecy - operational in classified environments
Hierarchical access controls for complex organisational structures including unit, rank, and clearance-level boundaries
Air-gapped update mechanism: security patches applied without external connectivity
Dedicated security assessment, architecture review, and deployment planning with Tosh Defence Private Limited
Zero-knowledge by design
Privacy architecture
Sanket.Enterprise is for organisations where 'we trust the cloud provider' is not an acceptable risk statement. Complete infrastructure ownership means communication data, encryption keys, identity records, and operational metadata never leave the customer's controlled environment - not in transit, not at rest, not ever.

Security model
The Sanket.Enterprise threat model assumes a sophisticated adversary with nation-state capabilities and supply-chain access. Air-gap capability removes the entire internet attack surface. Custom certificate authorities remove dependency on external PKI. Zero-knowledge architecture means even internal infrastructure access cannot decrypt communication content.

Deployment control

Frequently asked questions
Can Sanket.Enterprise operate with no public internet access at all?
Yes. Sanket.Enterprise is designed for this. All platform components - server, key management, update distribution, and identity management - run within your deployment environment. There is no runtime call to Sanket or Tosh Defence servers, no cloud dependency, and no external certificate authority required.
What are the infrastructure requirements for an on-premise deployment?
Requirements depend on deployment scale and the specific configuration. Tosh Defence Private Limited conducts a technical architecture review during the engagement process to define hardware, network, and operational requirements for your environment.
How does Sanket.Enterprise handle encryption key management in an air-gapped environment?
Encryption keys are generated and stored on user devices using hardware secure enclave where available. The server never holds private keys. In air-gapped deployments, key management infrastructure runs entirely within the customer's network with no external dependency.
How are security patches applied to an air-gapped deployment?
Tosh Defence Private Limited provides air-gapped update packages that can be delivered via approved secure channels and applied without internet connectivity. The update process is designed for classified environments with strict import controls.
What is the engagement and procurement process for Sanket.Enterprise?
Sanket.Enterprise deployments begin with a formal engagement process: security architecture review, requirements analysis, integration planning, and deployment scoping. Contact Tosh Defence Private Limited to initiate a classified or restricted evaluation process appropriate to your procurement framework.
Can Sanket.Enterprise integrate with our existing classified directory and identity systems?
Yes. Sanket.Enterprise supports integration with existing identity providers, directory services, and access management systems including custom internal certificate authorities. Integration requirements are assessed during the deployment planning phase.
