Sovereign Microsoft Teams Alternative for Sensitive Communication
Microsoft Teams is a powerful collaboration platform - but for organisations that handle classified information, national security data, or regulated communication, it represents a fundamental sovereignty problem. All communication, metadata, and identity data flows through Microsoft's US-hosted Azure infrastructure, subject to US legal process and foreign jurisdiction. Sanket provides a focused, encrypted communication platform under your sovereign control.
No Microsoft or US cloud infrastructure dependency
End-to-end encryption - not server-side encryption like Teams
Air-gap capable for classified deployments
Focused attack surface - messaging-only platform
The shift
Before Sanket vs. After Sanket
Before - current state risks
Sovereign deployment: your infrastructure, your jurisdiction - no Microsoft, Azure, or US cloud dependency
Focused secure messaging without the bloat of a full collaboration suite exposing additional attack surface
End-to-end encrypted channels that Microsoft Teams' server-side encryption model cannot match
Air-gap capable for classified environments where Microsoft Teams cannot be deployed at all
After - with Sanket
Zero dependency on Microsoft 365, Entra ID, or Azure Active Directory for identity management
Simpler security posture: a focused messaging platform has a smaller attack surface than a full collaboration suite
No Microsoft licensing exposure or vendor lock-in for communication sovereignty
Built for this
The architecture that makes secure alternative to Microsoft Teams under your jurisdiction work
Microsoft Teams processes communication metadata, meeting intelligence, and conversation content under US jurisdiction and Microsoft's own commercial terms. For government departments, defence contractors, and regulated entities, this creates data residency exposure and potential foreign intelligence access risk that cannot be mitigated through Azure configuration alone.
Zero-Knowledge Server
Microsoft Teams uses server-side encryption - Microsoft holds the keys and can technically access your communication. Sanket uses end-to-end encryption where Microsoft has no equivalent: the server holds only ciphertext that it cannot decrypt. For sensitive communication, this architectural difference is fundamental.
Signal Protocol E2E
Open-standard cryptography with Double Ratchet key derivation. Each message session generates unique ephemeral keys.
Admin Governance
Administrators control identity, groups, devices, retention, and access revocation - properties consumer apps cannot offer.
Sovereign Deployment
Organisations replacing Microsoft Teams for sensitive communication use Sanket.Work for managed sovereign cloud deployment. For classified or air-gapped environments where Teams is architecturally impossible, Sanket.Enterprise provides fully isolated on-premise deployment.
The result
What organisations achieve
Achieve genuine communication sovereignty by removing US SaaS dependency from sensitive internal messaging and moving to a deployment under national or organisational jurisdiction
Replace server-side encrypted Teams with end-to-end encrypted communication where the platform operator cannot access message content under any circumstance
Reduce attack surface and complexity by replacing a sprawling collaboration suite with a focused, auditable secure messaging platform
Evaluation guide
Questions every buyer should ask
Does the platform use end-to-end encryption rather than server-side encryption?
Is the platform deployable under national or organisational jurisdiction with no US cloud dependency?
Can the platform operate in air-gapped or classified environments where Teams cannot be deployed?
Is there zero dependency on Microsoft 365, Azure AD, or US commercial identity infrastructure?
Is the attack surface limited to secure messaging rather than a sprawling collaboration suite?
Can the deployment be integrated with our existing sovereign identity management systems?
FAQ
Frequently asked questions
What is the key security difference between Sanket and Microsoft Teams?
Microsoft Teams uses server-side encryption - Microsoft holds the decryption keys and can read your communication. Sanket uses Signal Protocol end-to-end encryption - the server stores only ciphertext and cannot decrypt messages. For sensitive communication, this is a fundamental architectural difference.
Why does Microsoft Teams create a sovereignty problem for governments and defence?
All Teams communication, metadata, and identity data flows through Microsoft's US-hosted Azure infrastructure. This creates US legal jurisdiction over government and defence communication, potential CLOUD Act exposure, and dependency on a foreign commercial provider for critical operational messaging.
Does Sanket support all the communication features we use in Teams?
Sanket provides secure one-to-one messaging, group channels, encrypted file sharing, and voice messages - the core communication functions most Teams users rely on. It does not include video conferencing, document collaboration, or project management features. For sensitive communication specifically, this focused scope is a security advantage.
Can Sanket work in environments where Teams is prohibited?
Yes. Sanket.Enterprise is designed for classified and air-gapped environments where commercial SaaS platforms like Microsoft Teams cannot be deployed. The entire platform runs within your infrastructure with no dependency on external services.
How long does migration from Teams to Sanket take?
Sanket.Work deployments can be operational within days to weeks. The migration timeline depends on identity integration complexity and the scale of the rollout. Tosh Defence Private Limited provides dedicated deployment planning support.
