Zero-knowledge encryption to protect sensitive emails
Only the best-in-class encryption is robust enough for sensitive emails and files.
Only the best-in-class encryption is robust enough for sensitive emails and files.
Email was never designed to be secure. Prevent the leading causes of data loss and email with total confidence by enhancing Outlook, M365, or Gmail with integrated zero-knowledge encryption.
Zivver uses TLS 1.2 and TLS 1.3, depending on the capabilities of the user (RFC 5246), meaning your data remains safe from the moment you click send.
For every secure email, including guest account conversations, an AES-256-CTR encryption key is used to protect the message content. The unique encryption key for each conversation is further secured by encrypting it with a separate key specific to the guest conversation.
Large file transfer sites aren’t always compliant or convenient, for employees or their recipients.
Regardless of size, if it’s sensitive - encrypt it. Zivver enables secure large file transfer up to 5TB from email. Contracts, PII, healthcare data - whatever you need to share, send it by email with zero knowledge encryption.
Zivver provides legally verifiable Proof of Delivery, enabling you to keep track of the status of emails. Apply 2FA and expiration controls, according to your organization’s privacy policies, to manage access to your data even after sending.
Right-sized security and data loss prevention controls ensure your emails are protected according to their sensitivity.
“For sharing personally identifiable information, for example, or financial information with contractors, Zivver ensures data is protected. The ability to share large files directly from Microsoft 365 is also very helpful. While compliance wasn’t the main reason for implementing Zivver, it is very important. We can access data and reporting on user activity in the back end, including some interesting statistics regarding data incidents avoided. We can even see when emails have been recalled. This data supports us in meeting compliance.”

Whatever you need to know, we’ve got the answers.
Traditional encryption methods often involve the service provider having access to the encryption keys or storing them on their servers, which can be vulnerable to breaches or unauthorized access. In contrast, Zivver's Zero Knowledge Encryption operates on the principle that Zivver itself does not have access to the encryption keys, meaning it cannot read or decrypt any data transmitted through its platform.
This “keyless” encryption model ensures that data security is solely in the hands of the users, providing a higher level of privacy and control compared to traditional methods. This approach is particularly beneficial for organizations needing to comply with stringent privacy regulations and those prioritizing user privacy and data security.
Zivver’s Zero Knowledge Encryption is designed to meet the strict requirements of various data protection regulations such as GDPR, HIPAA, and ISO standards.
By ensuring that only the sender and intended recipient have access to the content of the communication, Zivver's encryption method aligns with the core regulatory requirement to safeguard sensitive data against unauthorized access.
Additionally, because Zivver does not store or have access to encryption keys, it minimizes the risk of data exposure in the event of a breach, thereby helping organizations maintain compliance with privacy laws and regulations worldwide.
No, due to Zivver’s Zero Knowledge Encryption model, Zivver cannot access or recover encrypted data if a user loses access to their encryption keys.
This is because Zivver does not store or have access to these keys. The encryption keys are only accessible to the user who created them (the sender or the recipient).
While this provides a high level of security and privacy, it also means that it is essential for users to securely manage and back up their encryption keys, as losing them would result in the permanent inability to decrypt the stored information.
