USS SHIELD · Secure communications

Secure calls. Seen only as far as necessary.

UTalk is the USS SHIELD line for two-person voice and video when communication has to stay private: relayed only through USS servers, encrypted end to end, no accounts, no recordings, nothing stored. Every link works for 24 hours.

Open a secure room

The link works for 24 hours. Share it only with the person you are calling: anyone holding it can join.

USS SHIELD clients

Connect only from your secured device and only as your operator instructed, through a USS access node.

  • PARIS
  • USA
  • SPAIN
  • MALTA
  • LT

USS SHIELD creates location and IP noise and masks your origin on the way in, so your real position never meets the call.

External participants

Send the link to the person you need to speak with. They join publicly, from any network and any modern browser, with nothing to install. The call still runs only through USS servers: they never see your address or device, and you never see theirs.

Secure zone

When both participants are USS SHIELD clients connected through USS nodes, the room opens an additional end-to-end encrypted channel for exchanging documents. Files travel device to device and are never stored on any server.

Built-in safeguards

  • Relayed only through USS TURN servers. A direct connection between participants is impossible by design.
  • End-to-end encryption (DTLS-SRTP). The relay carries the call without being able to read it.
  • Two people per room. A third is refused.
  • No addresses, device names or browser details reach the other side.
  • Continuous verification during the call. Any tampering is reported in the room and ends the call.
  • No accounts, no recordings, no logs of addresses, links or call content. After 24 hours the room is erased.

    End-to-end encrypted, device to device. Not stored on any server.

      Communication protected. No intruders: two participants only. No data leaks: neither side sees the other's address or device. If a security test or intrusion attempt is detected, you will be informed directly here. If communication is compromised, the call is disconnected.
