End to end security is an added layer of application security. Zoom can encrypt all presentation content at the application layer using TLS 1.2 with Advanced Encryption Standard (AES) 256-bit algorithm.
This is configured at the account level (all users must follow) or user level. Once it is enabled, all meetings would be required to be AES encrypted.
End to end encryption is also designed to facilitate HIPAA based compliance requirements.
- It will force encryption across Zoom running on desktop, mobile and Zoom Rooms, as well as for H.323/SIP endpoints except PSTN telephone.
- It will also force end-to-end group messaging.
- Encryption may impact performance as it requires more processing cycle on the end devices.
How do I enable end-to-end encryption:
Select "Edit" under "Security" and enable "End-to-end encryption"
End to end encryption icon:
There is a lock icon when a meeting has end-to-end encryption enabled in desktop and mobile clients.
