You likely already use end-to-end encryption in some form or another. It’s on by default for iMessage and WhatsApp, a staple of encrypted messaging platforms like Signal, and an optional feature in Facebook Messenger. For video chat, your options are more sparse. Apple offers it for up to 32 participants on FaceTime, while WhatsApp allows up to eight people at a time. Signal can manage only one-on-one encrypted calls at the moment. Suffice to say, it’s a hard thing to get right.
And so Zoom went on a spending spree, bringing on high-profile consultants from the world of cryptography and buying up Keybase, a company that specializes in end-to-end encryption. The result of that flurry: Zoom finally delivered on its security promises at the end of October.
What Zoom launched is actually a 30-day technical preview; the company will continue to refine the offering through next year. But even in its early days, it offers a significant upgrade in protection for those who need it most.
