Security notifications

Your organization has drawn up various rules to ensure that sensitive information is always sent with Zivver. Zivver uses security notifications to inform you when a certain rule has been activated.

Read receipts

You can view a read receipt for each message sent. That way you know who has read your message and who has not. You will find this read confirmation in the form of a small envelope icon in the lower left corner of a sent Zivver message. Click on the envelope icon to see if the message was opened.

Message revocation

Zivver messages can be revoked at any time after being sent, either for every participant (including the sender) or just for recipients. Message revocation can be scheduled to occur after a set period, or immediately. Revocation is designed to fulfill two major functions: - You can withdraw a message that was sent in error. - You can comply to rule where laws or organizational policy require that copies of messages are not kept indefinitely.

You can revoke sent messages, or set messages to expire, before or after sending.

Set revocation for new messages

1. Click the revocation pass:[ history ] icon in the bottom of your message editor pane
   A new window titled Revoke access to message appears
2. Click Revoke for recipients if you want that the recipients have no access to the message. OR
   Click Revoke for everyone if you want that the recipients and you have no access to the message.

1. Click Revoke in if you want the message to be revoked later
   OR
   Click Revoke Now if you want the message to be revoked immediately.
2. Set a time period using the input box and the drop-down selector. Your organization may or may not have set a default period.
   The scheduled message revocation date displayed changes, in accordance with the time period you choose.

3. Press Revoke
   If you have chosen to revoke the message Revoke in, a light blue banner is displayed above the message header, stating the revocation period
   If you have chosen to revoke the message Revoke now, a greyed-out banner is displayed above the message header, stating that access to the message was revoked.

   Revoking a message will remove it from the Zivver inboxes of all recipients, including those you have added in CC: and BCC:.

Change revocation settings for sent messages

1. Navigate to your Sent messages Gmail folder
2. Locate and click on the message you wish to revoke or change revocation settings for. Zivver messages contain the string [This message is encrypted with Zivver] in the subject line
3. Click Edit Settings in the top right corner of the message pane.
4. Make changes as needed.
5. Click Set.

Recipient verification

Zivver attempts to verify recipients’ identity by means of checking that the recipient is in possession of a preshared secret - usually an access code, sent by means other than email. For details, refer to Verification Methods.

Personal Settings

Click Personal Settings in the extension menu to change Zivver settings. Please refer to the Zivver WebApp user manual for information on the various settings.

Business rules

Zivver Chrome Extension for Gmail monitors the Gmail message editor window and might produce warnings when you add possibly sensitive information to a message or trigger another Zivver business rule. Business rule violations can prevent that the mail client sends messages through Zivver. In such cases, the SEND button in the editor is unavailable until the issues are resolved.

To address this:

1. Click the pass:[ warning ]Issues button in the top right corner of the message editor window.
   A window titled Security issues pops up, listing issues with your message and possible actions.
2. Click Ignore to tell Zivver to ignore a particular issue.
3. Click OK to close the security issues notification window and return to the editor.
4. Change or remove any elements of your message that are triggering warnings.
