I had a client contact me recently about email encryption. I new already that there were 3 ways to go about this:
- You can use a service that manages the encryption.
- Install an encryption gateway at your office.
- Or install a desktop app that you have to manage public and private keys for.
This is a necessity for many that send sensitive email because once an email leaves your organization it is no longer encrypted.
Example 1: You have hotmail account and you email a yahoo account: the email is not encrypted once it leaves hotmail’s servers. and visa versa.
Example 2: You have an Exchange Server in your organization and you email another company out there that has an Exchange server by default these messages are not encrypted either. **
While I was updating my pricing list for different services to recommend, I found a very compelling new service: http://www.sendinc.com
The service does not store any of your data. You go to the main page which has the email form on it. After you type in your email address they require you to register. You then create your message and choose who you want to send it to. You can attach as much as 10 Megabytes of attachments. The message is encrypted and then attached to an email that is emailed to the recipient. So the message is no longer stored at Sendinc. When the end user opens the website attachment the data is uploaded to the website and decrypted there. All data transmissions are RSA SSL encrypted (1024 Bits). Even if you forward your email to someone else they cannot read it. It has to be opened from your email.
I give this web app two enthusiastic thumbs up!
