Analysis

OVERVIEW

Briar routes peer-to-peer encrypted messaging over Tor, Wi-Fi or Bluetooth with no central server, and its privacy policy states message content and metadata are not accessible to the operator.

LIMITS

The record documents more than $361,100 in Open Technology Fund grants tied to US State Department and USAGM channels, plus Internews and NLnet support, a funding history it flags as relevant to US or EU government threat models.

USEFUL FOR

Activists and journalists who want server-less peer-to-peer messaging and are willing to weigh the project's public-interest grant funding.
