What is Zero Download Manager (ZDM)?

The Zero Download Messenger (ZDM) is an interface that allows subscribers to initiate secure email without the need to install Voltage SecureMail Cloud software. It also allows your recipients to read your secure email and reply securely. The ZDM is not a web mail system and does not store/archive any secure email. Messages will only be stored in your sent folder and recipient’s inbox. How does it work? When clicking on the “Read Message” button, recipients use their browser to post the encrypted content to the Voltage cloud temporarily. Voltage then authenticates the recipient, decrypts the message in memory and displays it back to the recipient via a secure browser session. When the secure browser session is ended, the message will no longer be in server memory. The Zero Download Messenger requires that users log in each time they access the system and the secure session will timeout after a short amount of time for security purposes. Go to the Zero Download Messenger, click the “Compose” button and send an encrypted message. Tip: If you initiate secure email, click “Copy Me” to send a copy of the message to yourself for your own records.

How do I reset a password?

You can login to ZDM interface HERE then after entering your email address choose “Forgot Password” to reset the password.

Why do I need to encrypt my emails and files?

Email and file encryption are a proven approach to protecting sensitive information. In many cases encryption is necessary to ensure you are protecting client or patient information, in other cases because you need to protect intellectual property or other information that is confidential. Aside from the security and confidentiality concerns of using email in day-to-day business, email and file encryption is being adopted by growing numbers of users because of compliance issues. Specifically, legislation such as Sarbanes-Oxleyand the Health Insurance Portability and Accountability Act (HIPAA) have imposed stringent rules on the ways in which personal financial data and health information can be transmitted and shared. Firms failing to comply with these laws face severe sanctions and fines. In addition, the European Union and other international bodies have enacted privacy legislation that is affecting firms doing business overseas. For these reasons a secure email and file capability is now an essential tool for doing business at most publicly traded companies, firms providing health care or financial services, insurance companies, and the professional firms servicing these industries.

What makes VSN different from other encryption solutions?

Voltage Security – Data Security encryption products are so much easier to use than conventional encryption products because they are based on the breakthrough technology known as Identity-Based Encryption. With this technology, the Voltage SecureMail Cloud provides the most transparent experience for end users. Sending a secure encrypted email is as simple as clicking a button, and messages can be read anywhere, anytime through a browser-based interface. The Voltage SecureMail Cloud also doesn’t have the overhead or risks of a webmail system. No messages are stored on the service, so you and your recipients have complete control over all secure content.

How can I be sure that no one else see the content of my messages?

The Voltage SecureMail Cloud is a true point-to-point encryption service for email. This means that once you have encrypted a message, it remains unreadable until it is received and decrypted by the intended recipient.

Can IT managers or my ISP see my email?

No. Not even your IT department or ISP will be able to access your messages. Which is why the Voltage SecureMail Cloud is so valuable to executives and professionals working on sensitive business matters such as mergers and acquisitions, contract negotiations, new product development or human resource issues.
