The rise in data breaches and cyber threats has made organizations increasingly aware of the need for more secure communication. With traditional communication methods such as regular cell service, email, instant messaging, or social media leaving sensitive information vulnerable, organizations want solutions that make privacy and security their prime concern. End-to-end encryption offers a solution to this growing concern.

After years of intense standards development, the Internet Engineering Task Force (IETF) officially published today Messaging Layer Security (MLS) as RFC 9420. MLS is the first global open standard for end-to-end encrypted communications and has been jointly developed by industry peers and academic institutions. Wire was an initiator of MLS in 2016 and has been a key contributor ever since.
