6 reasons to choose Zivver over Egress

Zivver doesn’t have access to your decryption keys

With the invalidation of Privacy Shield and recent attention of zero-trust, we recognize the risks associated with vendors having access to data sent or received by your organization.

Zivver has no way to access any of the information you securely sent or received, because we simply don't have access to the decryption keys for any of our users. Other vendors including Microsoft 365, Google and Egress, can gain access to data of users *, making them vulnerable to insider threats, attractive to hackers and subjective to governmental subpoenas. Our zero-access key policy helps solve some of the biggest security and compliance challenges your organization may face in the cloud.

Zivver protects sensitive information with multi factor authentication

Most organizations share information that (from a privacy law perspective) requires person to person protection. Information such as your medical records, personal finance or tax information and more.

‘Regular’ email can only ensure server to server protection. Zivver goes to the next level and adds smart and effortless multi-factor authentication (MFA), not only for senders but also for recipients. This ensures you can adequately protect the data you send according to GDPR, ICO and NCSC guidelines on this topics and finally share even the most sensitive types of information legally.
Zivver uniquely protects sensitive information with external recipients with MFA.

Zivver doesn't force your recipients to create accounts

At the heart of a secure email communication is the sender and the recipient. We believe the experience should be effortless, without major hoops to jump through, such as forcing recipients to create accounts or insisting that they answer a secret question like ‘What was the location you got married?’ This increases barriers to effective communication and actually lowers security, because people will choose weak passwords. Especially when you use these solutions to communicate with a large number of individuals, such as patients, civilians or clients.

Zivver doesn’t require recipients to create accounts at all, significantly increasing adoption and the user experience of interacting with your organization. Egress forces recipients to create accounts if you want to protect sensitive information sent to recipients with unclear security and with certainty beyond just transport security, as required under GDPR, ICO and NSCS guidances, without the burden of having to exchange pre-shared secrets.

Zivver provides legal proof of receipt and access

Sometimes you need to be able to legally prove that information was sent to a specific individual, on a certain date, via a secure and recorded method, with confirmation that the recipient received or accessed the information. To date, you may default to using a secure postal service - which can be costly and time consuming.

Zivver is one of the few providers that can act as a full Electronic Registered Delivery Service (ERDS), providing the legal proof of receipt you need.

Send and receive massive files (no 50MB cap)

With Zivver you can send and receive massive files of any file type, up to 5TB. Egress limits the size of files freemium recipients can send back to your organization to 50mb, meaning you still need alternative solutions to be able to receive large files. With Zivver you can do away with alternative file transfer services and tools and streamline workflows.

Zivver seamlessly supports secure working from group mailboxes

Working from group mailboxes, functional accounts, delegated accounts and more is essential and commonplace. Making these communications highly secure shouldn’t create an additional burden for your IT department; manually managing the accounts.

Zivver seamlessly and effortlessly syncs accounts from your source system like Active Directory, and ensures your users are automatically authenticated to the appropriate mailbox with full logging and audit trailing.

Hear from others

“We’ve used Zivver so much more than any other tools available to us, including our historical digital communications solution, which is one of the reasons we switched; uptake across the trust of the old platform was very low. With Zivver, uptake is considerably higher - it has skyrocketed, and that’s because it’s so simple to use.”

Sarah Judge, Digital operational lead & CCIO, West Suffolk Foundation Trust

“We’d been using an alternative email security solution for approximately five years. For quite a few reasons, we were looking for an alternative and, for me, user experience was a priority. Zivver is an easy to use solution, for both employees and recipients; this is one of the reasons we chose Zivver.”

James Ryan, Infrastructure Manager, Soha Housing

"A secure email solution also matches our company DNA and is something we should be able to offer our customers.” Says Mario Vermunt. “Now we send and receive sensitive data securely using Zivver. And that's a reassuring thought.”

Mario Vermunt, Marketing & Communications Director, AT Osborne

* Typically vendors respond with ‘they don't have access to your data and that keys are managed well’. There is a test that will tell you whether this claim might be true. 1) create a (free) account. 2) choose a password 3) send this account a secure message from another account, 4) open this message from your newly created account, 5) before logging in, indicate that you lost your password, 6) finish the password reset procedure, sometimes involving contacting their support, and choose a new password, and finally 7) log into you account with the newly created password and try to read the message received in step 3. Are you able to read the message? In that case you know that your vendor stores a copy or derivative of the keys to your account and/or messages. Because how otherwise could they have given you access to a message that was sent to an account to which you lost your message?
