Transport Layer Security Software | Zivver
Transport Layer Security for every email
Protect every email and file attachment with enforced transport security
What it does
When it comes to protecting data in transit, Transport Layer Security is a failsafe measure that ensures every email leaving your server is secure and protected against unauthorized access - something you can’t guarantee with standard email.
- Opportunistic TLS (the standard level of encryption provided by most email clients) isn’t failsafe. Zivver enables you to send all your emails with a minimum level of security at all times, to guarantee your data is protected.
- Meet compliance with evolving data protection regulations by enhancing your email client and enabling transport layer security for every sensitive email.
- Email securely, safe in the knowledge that your data is protected against common malicious threats, including man-in-the-middle attacks.
How it works
Transport security without the downsides
If the recipient’s mail server supports a minimum level of transport encryption and server authentication, Zivver can deliver secure messages directly. If not, they can still be accessed via our portal.
Encrypted in transit
Every Zivver message is encrypted and sent securely
Enforced TLS ensures that emails are encrypted during transmission, preventing unauthorized access during transit - crucial for protecting sensitive data from being intercepted.
Maximum delivery assurance
Enforced transport security without the hassle
When transport security is enforced by standard email solutions such as M365 and Gmail, messages are not delivered to recipients who do not support the required level of security set by the sending organization. The sender then receives a return message — a so-called “bounce.” This creates unworkable situations.
Zivver solves this problem by automatically falling back to delivery via a secure message portal in such cases. The sender doesn’t have to do anything and won’t even notice the difference, while the security and integrity of the email remain fully guaranteed!

Frequently asked questions
Whatever you need to know, we’ve got the answers.
What type of encryption does Zivver use to protect my data?
Zivver uses a combination of secure-TLS and zero-access-encryption to protect your data in transit and at rest. Additionally, Zivver employs keyless encryption, meaning that only the sender and recipient have access to the encryption keys, ensuring that even Zivver cannot access the content of your communications.
Can Zivver access the content of my encrypted emails?
No, Zivver cannot access the content of your encrypted emails. Zivver uses zero-access-encryption, meaning that only the sender and recipient have the keys needed to decrypt the content. This ensures that your data remains private and secure, even from Zivver.
What is the difference between TLS encryption and end-to-end encryption?
TLS encryption ensures that the connection between two servers is secure and that data in transit cannot be intercepted. End-to-end encryption (E2EE) ensures that the content of an email remains protected from the moment it is sent until the recipient opens it. Zivver uses zero-knowledge encryption, which combines strong encryption in transit and at rest to achieve nearly the same level of security as E2EE—without the major drawbacks of E2EE, such as requiring both sender and recipient to use the same solution and preventing organizations from effectively applying DLP (Data Loss Prevention).
