SANKET vs Rocket.Chat: secure team messaging compared

Rocket.Chat is a flexible team collaboration platform that can run on-premises and air-gapped. SANKET is end-to-end encrypted by design for every message, file and call, with Signal's libsignal, post-quantum PQXDH and SPQR, signed device lists and device mutual TLS, under the organisation's full control.

SANKET vs Rocket.Chat: side by side

Who controls the infrastructure

SANKET

The customer. One dedicated installation per organisation, on infrastructure it owns or chooses, with no vendor-operated service in the message path.

Rocket.Chat

The customer (self-managed) or Rocket.Chat's hosted cloud.

Deployment options

SANKET

Dedicated installation on any cloud in any region the customer chooses (or Tosh Defence hosting), customer on-premise, or fully air-gapped; single host or high availability with second-site recovery.

Rocket.Chat

On-premises, air-gapped, sovereign or private cloud, or Rocket.Chat hosted cloud.

Who holds keys and identity

SANKET

The customer and its users. Keys are generated on each device and protected by hardware-backed storage; identities are customer-controlled Sanket IDs, with no consumer phone-number identity required.

Rocket.Chat

Workspace accounts; no phone number required. Key management: not publicly documented.

Encryption protocol

SANKET

Signal Protocol through Signal's official, independently audited libsignal. Messages AES-256-CBC with HMAC-SHA256 inside libsignal; files and calls AES-256-GCM; TLS with AES-256-GCM suites only.

Rocket.Chat

Not publicly documented

Post-quantum protection

SANKET

Yes, in the current release: PQXDH with a mandatory post-quantum Kyber prekey and the SPQR ratchet (Triple Ratchet), plus hybrid X25519MLKEM768 key exchange at the TLS edge.

Rocket.Chat

Post-quantum algorithms on the vendor's roadmap.

Groups and calls end-to-end encrypted by default

SANKET

Yes. One-to-one and group messages, reactions, encrypted broadcasts and files are always end-to-end encrypted; voice and video calls use AES-256-GCM frame encryption with five new frame keys per second, inside SRTP AES-256-GCM.

Rocket.Chat

End-to-end encryption is enabled by a workspace administrator, who can enforce it for new private rooms and direct messages.

Customer identity provider (SSO / LDAP)

SANKET

Yes. Sign-in through the customer's own OIDC, SAML 2.0 or LDAP directory, SCIM 2.0 provisioning, and FIDO2 security keys for administrators.

Rocket.Chat

LDAP, SAML and OAuth / OpenID Connect (for example Keycloak and Entra ID); LDAP and SAML use a Premium module from version 9.0.0.

Admin controls and device governance

SANKET

Device approval and revocation, lost mode and remote wipe, signed device lists, device mutual TLS, retention, forwarding and clipboard policy, customer-defined classification labels and a hash-chained audit log for the customer's SIEM.

Rocket.Chat

Not publicly documented

Data sovereignty (jurisdiction, built in India)

SANKET

Built in India by Tosh Defence. Data stays in the jurisdiction and on the infrastructure the customer chooses, with no third-party analytics and no foreign runtime dependency in the products.

Rocket.Chat

Rocket.Chat Technologies Corp, Porto Alegre, Brazil, with offices in the USA and Europe.

Release integrity and update control

SANKET

Ed25519-signed releases verified before install, with release freeze and rollback protection and automatic rollback on a failed upgrade. The customer decides when to upgrade, online or with a signed offline package.

Rocket.Chat

Not publicly documented

Platforms

SANKET

Native apps for iOS, Android, Windows, macOS and Linux. Browser-free by design: there is no web client to attack.

Rocket.Chat

Web, desktop and mobile (vendor).

Where SANKET leads

  • End-to-end encryption by design for all messaging: messages, reactions, broadcasts and labels go through libsignal, and files are encrypted with AES-256-GCM on the device.
  • Post-quantum messaging in the current release (PQXDH and SPQR) and hybrid post-quantum TLS at the edge.
  • Calls end-to-end encrypted with per-sender AES-256-GCM frame keys delivered over libsignal; the media server cannot decrypt them.
  • Signed device lists and device mutual TLS for every approved device.
  • FIDO2 security keys for administrators, verified by the installation itself with no external service.

Frequently asked questions

Is SANKET a Rocket.Chat alternative?

Yes, for organisations that want every conversation end-to-end encrypted by design. SANKET (Sanket.Chat) by Tosh Defence uses Signal's libsignal with post-quantum protection for every message, file and call.

Can SANKET be air-gapped?

Yes. SANKET runs fully air-gapped with an internal certificate authority, offline licences and signed offline updates, single host or high availability with a second site.

Does SANKET integrate with LDAP and SAML?

Yes. Sign-in can be federated to the organisation's own OIDC, SAML 2.0 or LDAP directory, with SCIM 2.0 provisioning.
