VK WorkSpace Federation Enables Secure Multi-Organization On-Premise Messaging Without Infrastructure Merge

VK Tech has released federation capabilities for its VK WorkSpace corporate messenger that connect independent On-Premise installations while preserving each organization's full control over data, administration, and security policies. The feature, first piloted in November 2025 and expanded in the July 2026 26.2 release, supports multi-party chats across more than two separate environments. Federation relies on mutual trust establishment and per-user access grants rather than full directory replication or proxy access to a single host instance. Each participating organization maintains local copies of messages, files, and chat metadata, allowing continued access even if a partner installation becomes unavailable. The architecture deliberately avoids both centralized hosting and open protocols such as Matrix to keep changes to the existing messenger core minimal. Administrators retain independent levers to create or revoke trusts and to limit which employees may communicate externally.

Bypassing Blocks, Privacy, and Anonymity Remain Separate Challenges for Decentralized Networks

The developers of the decentralized circumvention tool Tunnel Cat have clarified that their service addresses only traffic delivery and does not guarantee privacy or anonymity. Transport-layer TLS encryption protects data in transit between nodes but provides no end-to-end protection for conversation content. The team explicitly recommends using separate E2E-encrypted messengers such as Signal or Matrix rather than relying on Telegram. Operational telemetry is retained to comply with legal obligations in multiple jurisdictions and to monitor blocking patterns inside Russia. Because client devices relay traffic for others, the architecture inherently prevents strong anonymity guarantees comparable to Tor. The project deliberately separates the circumvention function from messaging and anonymity tools to avoid overpromising security properties.
