How does Zivver Secure Email protect my messages?

Zivver uses zero-knowledge, AES-256-bit encryption to secure emails both in transit and at rest, meaning only you and the intended recipient can access the message content. Not even Zivver can decrypt your data. Additional safeguards include multi-factor authentication (MFA) and recipient identity verification, reducing the risk of unauthorized access. Combined with smart data loss prevention (DLP) features like real-time alerts, Zivver helps stop mistakes before they happen.

Can I send secure emails to recipients who don’t have a Zivver account?

Yes. Zivver allows you to securely email anyone, even if they don't have a Zivver account. When you send a secure message, the recipient receives a notification with a secure link. After verifying their identity through 2FA (depending on your preferred authentication method), recipients can view and securely respond to the message in Zivver’s secure environment. For ongoing use, recipients can create a free Zivver account to streamline future communication. Learn more about our top-rated recipient experience.

What measures does Zivver take to prevent sending sensitive information to the wrong recipient?

Zivver uses intelligent error detection based on user behavior and machine learning. For example, Zivver identifies unusual recipients in the ‘to’ field, misuse of Bcc, as well as sensitive data in the body and attachments - providing real-time alerts before you press send. These warnings help prevent common mistakes like misaddressed emails or unprotected attachments. If something slips through, you can instantly revoke access to the message, keeping sensitive data under your control.

How does Zivver support organizations in meeting compliance requirements?

Zivver is designed to support compliance with global and industry-specific regulations such as GDPR, HIPAA, NIS2, DORA, and NTA 7516. By securing both the content and the context of communication, Zivver ensures that sensitive data is protected throughout the entire message lifecycle. Built-in audit trails, access logs, and proof of delivery help meet legal obligations and simplify audits. For further support on meeting your compliance requirements, check out our webinar to explore the real-world impact of evolving regulations. We also address emerging challenges such as AI, Post-Quantum Cryptography, and strategies for aligning information security with broader business objectives.
