SANKET vs Wire: a Wire alternative with post-quantum Signal Protocol
Wire and SANKET are both built for organisations and both deploy on-premises and air-gapped. SANKET stands out with Signal Protocol and post-quantum PQXDH and SPQR in the current release, AES-256 on every layer, device mutual TLS and signed device lists, from an Indian vendor with offline licensing.
About Wire
Wire Swiss GmbH · Switzerland
Wire is a Swiss secure collaboration platform for enterprises and governments, with hosting in Germany and Ireland. Messages, calls and files are end-to-end encrypted by default and cannot be disabled, and it moved to the MLS protocol across its products in April 2025. It offers cloud, private cloud, on-premises and air-gapped deployment with SAML SSO and SCIM.
SANKET vs Wire: side by side
| Criterion | SANKET | Wire |
|---|---|---|
| Who controls the infrastructure | The customer. One dedicated installation per organisation, on infrastructure it owns or chooses, with no vendor-operated service in the message path. | Wire operates its cloud, or the customer runs a private cloud or on-premises installation. |
| Deployment options | 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. | Cloud, private cloud, on-premises and air-gapped (vendor). |
| Who holds keys and identity | 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. | SSO and SCIM users join by email invitation, without a phone number. Key management: not publicly documented. |
| Encryption protocol | 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. | MLS (generally available since April 2025), with Proteus also documented; conference calls AES-GCM 256. |
| Post-quantum protection | 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. | Described as designed for cryptographic agility; a deployed post-quantum key exchange is not publicly documented. |
| Groups and calls end-to-end encrypted by default | 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. | Yes: messages, calls and files end-to-end encrypted by default and cannot be disabled. |
| Customer identity provider (SSO / LDAP) | 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. | SAML SSO and SCIM provisioning. |
| Admin controls and device governance | 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. | Not publicly documented |
| Data sovereignty (jurisdiction, built in India) | 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. | Wire Swiss GmbH, Switzerland; hosting in Germany and Ireland. |
| Release integrity and update control | 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. | Not publicly documented |
| Platforms | Native apps for iOS, Android, Windows, macOS and Linux. Browser-free by design: there is no web client to attack. | Desktop, mobile, browser and tablet. |
Who controls the infrastructure

- Signal Protocol with post-quantum protection deployed today: PQXDH and the SPQR ratchet for all messaging.
- AES-256 or nothing: calls refuse any device or offer below the AES-256 profile, and TLS suites are AES-256-GCM only.
- Device mutual TLS for every approved device, with keys generated in hardware-backed storage on phones.
- A sovereign Indian vendor with offline licensing and signed offline release packages for air-gapped estates.
- Signed device lists maintained on the customer's own installation.
Frequently asked questions
What is a good Wire alternative?
SANKET (Sanket.Chat) by Tosh Defence: Signal Protocol with post-quantum PQXDH and SPQR, AES-256 on every layer, and deployment from dedicated cloud to fully air-gapped under the organisation's control.
Does SANKET support SSO and SCIM?
Yes. SANKET supports SCIM 2.0 provisioning and sign-in through the organisation's own OIDC, SAML 2.0 or LDAP directory, plus FIDO2 security keys for administrators.
Is SANKET post-quantum?
Yes. Messaging uses PQXDH with a mandatory post-quantum Kyber prekey and the SPQR ratchet, and the TLS edge offers hybrid X25519MLKEM768 key exchange to clients that support it.
