What it does
Zivver provides encrypted email and large-file delivery within Outlook, Gmail and a web app. Its documented workflow checks messages before sending and verifies external recipients through a protected portal.
Zivver addresses errors as well as message encryption. The product overview describes checking a draft’s recipients and content before sending, then using recipient verification for protected delivery. That can help a team build a review step into an existing mail workflow.
External recipients can receive a link and verify access using a configured code, password or email method without creating a Zivver account. These methods are not interchangeable, so choose the verification policy around the information being sent.
Strengths
- Pre-send checks complement encrypted delivery.
- External recipients can access protected messages without creating an account.
- Outlook, Gmail and web-app routes are documented.
