As a kid I used to write messages with lemon juice and when the juice dried I had a secret message (or so I thought) that was viewable when held up to the light.
Of course these child hood secret messages only work in the mind of a child, but not the corporate shield of real business. For your communications between your employees, your partners or your clients you need to ensure that each email message that needs to be secure, is secure.
If you are in a regulated industry, the security of your email communications is even more important.
Sending encrypted email ensures that email you intend for a particular person or group of people is only read by that person or persons. From what I’ve seen there’s two types of email encryption.
Type one, encrypts email from within your email client and sends the email message as an attachment. The second type of encryption takes place within a web browser. There is nothing you download, but you view the message in a web browser. With this method you have tighter control over the message as you can indicate if the message can even be printed, or copied.
PDFs have similar options available to them, so creating a PDF with security policies can be one way to encrypt an email message as well.
An advantage to investing in a corporate email security system is that you can automatically enforce corporate security policies and more easily audit email messages. If you have a dispersed team of employees being able to ensure they can encrypt email, on demand, is important.
In particular as employees travel internationally, securing a hard disk is good, but if the email you send is not encrypted, and it should have been encrypted, an encrypted hard disk is only half protecting you.
Voltage Security is one of many secure communication vendors with email encryption solutions and one of their many clients is Domino’s Pizza. Karl Anderson, network security manager at Domino’s Pizza said, “At Domino’s we are in the process of implementing a corporate-wide data loss prevention initiative to avoid any accidental loss of private or proprietary information. We realized that emails being sent to partners and vendors, such as insurance providers, may contain information like social security numbers that must be encrypted before sending.”
Maybe you are not sending social security numbers, but have a contract with a big retailer or the Department of Homeland Security and you have to ensure your email communication to them, your vendors and partners, is safe but also easily accessible to the recipient. A solution such as provided by Voltage (or another vendor) could be what you need.

I wanted to know a bit more about how Voltage work and their spokesperson answer some questions below:
Can I control if the recipient can print or forward a message or how long they can view and etc the message
Yes, you can send and receive secure messages via the web. The really cool thing with Voltage is that it makes encrypting information simple, usable, manageable, and at a low cost, all for the first time. For example, software purchased at the Voltage Security Network (VSN) website at www.voltage.com/vsn is usable from the second you download it—it just works. You don’t have to know anything about encryption or public key infrastructure, there’s no learning curve, no management issues, nothing that would be a burden. You can use your regular email inbox for secure messaging, and just click a “SEND SECURE” button instead of just a “SEND” button. And, you can communicate securely with ANY third party without having to receive their public key or them having to download anything first. The features you describe that control messages even after the recipient receives the encrypted mail is really E-DRM (Enterprise Digital Rights Management), however you have rights controls using Voltage SecureFile.
For an attachment, this is something they would have to download to their computer as with any attachment and once decrypted they could then send to anyone else – Voltage could not control this – right?
Yes, in Outlook there is a “Send Secure” button. As soon as they receive the email, messages and attachments are available to them in the clear—even from within their email box. The recipient can forward to anyone else UNLESS they’ve encrypted the file and assigned rights using Voltage SecureFile.
What are the expected costs for say 10 seats? 50 seats?
The Voltage Security Network or VSN, which includes encryption for emails, files and documents, delivered as a fully managed or hosted service, is just $65 per user. Quantity discounts are available for groups over 100 (101-250, 251-500 users, etc.).
How do the recipients of the email get my public key initially?
The solution, which has been proven in the largest and most demanding enterprise environments over the course of many years (and is the fastest growing secure email solution in the world), is based on a breakthrough known as Identity-Based Encryption (or IBE), which is now also standard technology. No longer do you have to worry about getting people’s public key before being able to send a message, or manage keys, or know anything about complex cryptography at all. You can send a secure, encrypted message to anyone with a simple identifier such as their own email address! And once a message is sent, recipients can open, read, and respond securely with nothing needed on their end.
Here’s a link to a demo
And here’s a link to how this innovative technology works
If there is NOTHING for the end user to install how can they even open the first message?
The first time they receive an encrypted message, they’ll click a link to authenticate themselves and enter a password. This is all in the demo.
When you send an encrypted email to someone for the first time, the recipient receives an HTML attachment containing the message. When they open it in their browser, they read the email through a secure connection. It’s that easy! If, however, they wish to receive their secure mail in their own Outlook or Outlook Express email client, they can join the Voltage Security Network and install the Voltage SecureMail plug-in.
