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
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

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
