What is end-to-end encryption and why it matters

Video conferencing has been a key part of global team collaboration. Now that work-from-anywhere is spreading to local teams, video conferencing has moved from a key business enabler to a business necessity. 

You need to have confidence in your video conferencing and overall collaboration solutions. Are they always available? And are they “securely available”? And are your communications themselves available to you and your teams and no-one else? 

The first step to secure communication is to use encryption—an important method for businesses to protect their information. Encryption makes information unreadable, where only those individuals with the appropriate keys can decipher encrypted data and read it. 

Encryption is therefore an important way to protect your data, especially if that data has to be transmitted over a public network. Most secure communication protocols (such as TLS, HTTP/S) occur between systems, or “points,” and therefore provide “P2P” or point-to-point encryption. 

End-to-end encryption (E2EE) is the next step in secure communications. But what is E2EE, exactly? How does it secure messaging, video, and phone communications? What does it protect against? And who can access these E2EE communications? 

Let’s look at the basics.

Encrypted communications and video meetings  

Encryption of data in transit, over public and private networks, uses industry standard protocols to set up encrypted channels to protect data in transit between two points (known as point-to-point (P2P) encryption).

When used with standard protocols such as TLS, SRTP, even HTTP/S, P2P encrypted channels are established between two systems, such as the application used by the video participants and the video provider’s processing systems. – Read more
