Olvid instant messaging app

Olvid is a high-security instant messaging application developed in France. It distinguishes itself from competitors by being the first and only messaging app that does not require a centralized directory or the exchange of personal data such as phone numbers or email addresses to establish a secure connection. Instead, it relies on cryptographic protocols that verify identities directly between devices.

The company was founded by cybersecurity experts and researchers who aimed to create a 'trustless' environment where technical infrastructure providers have no access to user metadata. Since its inception, Olvid has gained certifications from security agencies like the ANSSI (French National Agency for the Security of Information Systems). In 2024, the brand reached a significant milestone when it was acquired by the French aerospace and defense giant Thales Group, which integrated Olvid into its secure communications portfolio while maintaining its commitment to privacy.
