RingCentral has expanded its End-to-End Encryption (E2EE) beyond video conferencing to include phone and messaging within its flagship RingCentral MVP product.

The E2EE technology prevents unauthorised third parties from accessing a user’s communication content.

By expanding its E2EE technology, RingCentral can ensure that it provides enterprise-grade confidentiality across chats, calls, and meetings.

Michael Armer, Chief Information Security Officer at RingCentral, said: “With RingCentral’s E2EE for video, and soon, phone calls and messaging, organisations can leverage RingCentral’s native capabilities to simplify their technology stack with one offering.

“We believe our approach to end-to-end encryption across message, video, and phone is truly differentiated and represents the most complete deployment of E2EE for enterprise communications to date.

“People exchange millions of calls and messages a day on RingCentral’s platform.

“With our new E2EE, we’re extending enterprise-grade privacy and security controls for our customers, giving them the freedom to have confidential conversations across any mode.”

Expanded Support Beyond One-to-One Calls and Messages

RingCentral’s expansion of its E2EE technology means there is now support for large groups rather than just one-to-one communication across message, video and phone.

Using Messaging Layer Security (MLS), the technology is scalable to ensure that all RingCentral users are supported.

This support exists when they communicate with others inside their organisation or with external parties.


RingCentral has ensured that E2EE is accessible on various devices and web browsers.

RingCentral customers are protected regardless of their working location or if they are communicating with people who have not downloaded the RingCentral app.

E2EE can be Enabled Mid-Meeting

The E2EE feature has been designed to be available whenever it is needed.

Users can enable E2EE for a scheduled call, an ongoing meeting or spontaneously, should it be needed.

In doing so, it lets meeting participants easily and securely switch devices mid-conversation without ending the call and setting up another encrypted meeting.

Privacy by Design

For organisations that have to abide by strict compliance measures, IT administrators can turn E2EE on or off at any time.

Administrators also have cryptographic access to messaging data and can export that data if needed.

RingCentral plans to “empower” customers to enable content capture and supervision with selected partners for E2EE voice, chat, and video in 2023.

Currently, E2EE for video is generally available to all RingCentral customers now.

The company has confirmed that a RingCentral E2EE for phone and message will be accessible in a closed beta for select customers worldwide by the end of this year.
