Our work

Read more about the different areas of our work.

At Phoenix R&D, we are passionate about enhancing the security and privacy of digital communications. Our approach is to get involved in specification work to design standards that impact technology globally, develop implementations to turn those standards into working software code, and finally building applications on top of those standards. Apart from that we also consult clients with a wide range of needs.

Messaging Layer Security (MLS)

Internet standards define the baseline for security and privacy in the applications we use everyday. Together with other organizations, we identified the lack of an open standard for end-to-end encryption. We co-initiated and co-authored the IETF standard Messaging Layer Security and contribute to advance the protocol with MLS Extensions. Additionally to MLS, we also work in the working groups More Instant Messaging Interoperability (MIMI) and Privacy Pass. Our role in these projects reflects our commitment to improving digital communication for everyone.


With OpenMLS, we develop and maintain one of the reference implementations of the MLS protocol. The OpenMLS library is written in pure Rust, licensed permissively and can be compiled for all targets supported by the Rust standard library, including Android, iOS, Windows, Linux, macOS, and WebAssembly. We work with industry, academia and communities to build a stronger secure messaging ecosystem through research and standardization.

Messaging Stack

Our work extends to developing open-source tools that give people more control over the way they communicate. We focus on creating a messaging stack that provides security through post-quantum resistant end-to-end encryption, and combines decentralization with minimized metadata exposure. Our goal is to provide individuals with greater control over their privacy and communication and organizations with better security for their sensitive data.

Consulting Services

Recognizing the complexities of digital security, we also offer consulting services in the realm of secure messaging, post-quantum resistance, and end-to-end encryption. Our approach is to work closely with our clients, understanding their unique needs and challenges, to provide tailored advice and solutions.
