Zero Knowledge Encryption Software | Zivver
Zero-knowledge encryption to protect sensitive emails
Only the best-in-class encryption is robust enough for sensitive emails and files.
Improve the security of your email client with integrated zero-access encryption.
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-access encryption.
- Unlike other email security providers, we don’t hold decryption keys - meaning only you and your recipient can access your data
- Send and receive secure emails by enabling two-way secure emailing with stakeholders, including third parties without Zivver accounts
- Combined with data loss prevention controls, zero-knowledge encryption enhances email with all the tools you need to meet compliance requirements
Enhance M365, Outlook, and Gmail with zero-knowledge encryption
Zivver stores messages and files using strong, proven encryption, ensuring that your communication is as well protected as possible against unauthorized access. The encryption used by Zivver meets the standards required by governments, banks, and other institutions, and can be upgraded to stronger algorithms if desired or necessary. This way, you can be confident that your data is secure—now and in the future.
Best-in-class encryption
Protection throughout your email’s journey
Zivver uses best-practice standards during transmission (TLS 1.3, or otherwise TLS 1.2 with approved cipher suites). This is the same technology used by government applications and banks. This ensures that your data is securely sent to our protected platform for analysis of viruses, human errors, and potential data breaches.
Every Zivver email—even those sent by guest users—is stored with strong encryption. Zivver does not have the keys to decrypt the emails and files; only the sender and recipient do. A unique key is used for each conversation.
Protect every email and file
Encryption for attachments
Most file transfer solutions do not meet compliance requirements and are inconvenient to use for both senders and recipients.
With Zivver, you can attach large files up to 5 TB directly from your mailbox. Contracts, PII, patient data—whatever you need to share, send it securely via email with zero-knowledge encryption.
Extra protection
Manage access to your sensitive data
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.
Zero Knowledge Encryption FAQs
Whatever you need to know, we’ve got the answers.
How does Zivver’s Zero Knowledge Encryption differ from traditional encryption methods?
With most “secure email” or “secure file sharing” solutions, the service provider has access to the decryption keys because they are stored on the provider’s servers. This makes them vulnerable to insider threats, attractive targets for hackers, and susceptible to government access requests, such as under the CLOUD Act.
Zivver’s zero-knowledge encryption is based on the principle that Zivver itself has no access to the keys needed to decrypt stored information. As a result, Zivver is immune to these risks.
How does Zivver ensure compliance with data protection regulations through Zero Knowledge Encryption?
Zivver’s zero-knowledge encryption is designed to meet the strict requirements of various data protection laws, including the GDPR, HIPAA, and ISO standards.
Because only the sender and intended recipient have access to the contents of messages and files, Zivver’s encryption method complies with the core requirement of these laws—to protect sensitive data from access by third parties. Since Zivver does not store decryption keys and therefore cannot provide access to information, the risk of a data breach is greatly reduced, even in the event of a server compromise. This also means that Zivver cannot disclose any data in response to potential government information requests.
Can Zivver access or recover encrypted data if a user loses access to their encryption keys?
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 decryption keys are only accessible to 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 decryption keys, as losing them would result in the permanent inability to decrypt the stored information.
Does Zivver’s Zero Knowledge Encryption impact the user experience or communication speed?
Zivver’s zero-knowledge encryption is designed to integrate seamlessly with your existing systems and email programs such as Outlook and Gmail, allowing you to work as usual without any noticeable delays. The security operates in the background and has no impact on the usability of your email or other software. This way, your staff can communicate efficiently while benefiting from the robust protection that zero-knowledge encryption provides.
