Zivver enables secure sending of emails, chats or file transfers, from anywhere Zivver is the only solution you need to send communications such as emails, chats and file transfers securely, from anywhere. Used by thousands of organizations to help safeguard sensitive data, enhance productivity and prevent data leaks. How Zivver works Most people realize that you shouldn’t send sensitive information such as financial details or health information by regular email, chats or file transfers, but often don’t know how to send it securely. That’s where Zivver comes into play. On top of using advanced end-to-end zero-knowledge encryption, Zivver identifies potential anomalies in real-time when you’re sending communications from our Web application, Outlook plug-in and mobile app. The non-intrusive prompts enable you to catch mistakes before hitting send without disrupting any workflows. This could be a simple case of not selecting the right recipient or including the wrong attachment (you know you’ve made a mistake like that before, we all have). Both of these scenarios are top data leak drivers that can be easily avoided when using Zivver. Those situations are very common and account for the highest share of data breaches overall. Some are minor embarrassments you try to quickly forget, others can be much more consequential and make headlines for all the wrong reasons. Either way, it’s best to avoid these situations altogether, and with Zivver you can. Easy to use, from anywhere No one should have to wait around for snail mail for a communication that can be easily sent securely to your inbox, just as you shouldn’t be using regular email to send sensitive information, it’s too risky. Zivver safeguards important communications while providing a user-friendly experience for the people you’re connecting securely with. Intuitive design principles make the service easy for anyone to use with minimal training. Recipients don’t need to create an account to access Zivver messages, but have the option to set up a free account if they want to. Get Started with Zivver 1.
