Secure

Send sensitive data safe in the knowledge that your files are protected by zero-knowledge AES-256-bit encryption​, 2FA, expiration controls and more.

Easy

Integration with Outlook and Gmail enables you to send large files securely by email, or just simply use the Zivver WebApp with no integration at all; say goodbye to risky third party platforms.

 

Compliant

Protect private data, preserve public trust, and effortlessly comply with global regulations including GDPR, NIS2, DORA, and HIPAA.

 

“Before Zivver, when people came up against the roadblock of needing to share a large file, they’d resort to platforms like Dropbox and WeTransfer. We don’t believe those solutions are secure enough. That was the attraction of Zivver. Every file and message is sent encrypted as standard.”

How it works

Protect your files from unauthorised and third party access

Your data is yours, meaning you need total control over who has access to it and how it is used. With Zivver, you can share files safe in the knowledge that no one can access your data other than you and your recipient - not even us.

Zero-knowledge encryption

Zero knowledge encryption means zero access to your data

Your files and emails are protected by zero-knowledge AES-256-bit encryption​ when you send with Zivver. This means we don't hold decryption keys and won't reproduce, modify, distribute or publicly display your files or data. 

Plus, for that extra touch of security, our revoke and expiration control tools empower you to manage access to sent files at any time, and control who accesses your files and when. You can even see who has opened your files after sending them.

Large file transfer integrations

Keep file transfer within email and stop relying on unreliable third parties

Enhance your email client (Gmail, Outlook, WebApp or M365) and put large file transfer capabilities within clicking distance for every user. Zivver also integrates with Purview and other secure labeling tools, meaning our solution can detect sensitive data in accordance with existing security policies.

Real-time alerts

Prevent the small mistakes with big consequences

Work confidently and securely with Zivver as your safety net. In accordance with your organization’s security policies, Zivver scans files and identifies sensitive data, alerting you in real-time when emails should be sent encrypted, or perhaps are about to be sent to the wrong person. 2FA controls also prevent unauthorized access.

Send files up to 5tb in size with confidence

Whatever the file, whatever the size, no-one other than you and your recipient can access them.
