Our company has many E-mail users. Ordinary E-mail is a great way to communicate but it is NOT secure. Very few people would send a letter to a customer or a friend without sealing the contents in an envelope but E-mail travels electronically without even the level of protection that a paper envelope can provide for a letter.
Most people assume that when they send an E-mail it is delivered directly to the intended receiver.
Unfortunately this is not the case. When you send E-mail it travels via numerous routers and servers and, in transit, may be stored at one or more locations. Your message, together with your digital signature, may later be retrieved and read by a third party without your consent. To access mailed SAFE services you need a connection to the Internet and an e-mail account. When you send E-mail using mailed SAFE encryption, any attachment files such as text documents, spreadsheets, or image files are also encrypted.
