But what is Sophos Free Encryption for?

Well, imagine the old days of telephone party-lines. We've all heard about them - where neighbors would listen in on your grandparents' phone conversations. Now scale that up to a party line with hundreds of millions of people on it. That's kind of like how email works today.

From our daily messages home sorting out dinners to some of our most sensitive email exchanges with partners and suppliers, they go across the public internet.

Sophos Free Encryption

Now, no-one get too concerned just yet. No, its not likely that your neighbor knows your meal preferences or local town gossip. Thanks to a lot of complex networking gear, no one PC actually "hears" most of the email traffic. Instead email is smartly routed through a series of computers to reach its intended vicinity.

That said, email does pass through an often unpredicted set of hands (computer servers) to transfer from sender to recipient. Across these very hands, millions of messages containing sensitive information travel. Many businesses have begun to protect themselves using technologies such as "transport layer security" and other email encrypted technology.. but what are you doing?

Its likely that if you don't know the answer to that question. You probably aren't using anything to protect your information - especially information sent to and from your home. So what should you do?

For the average consumer out there, there are a few recommendations that can help safeguard your information. Follow these simple guidelines to reduce the risk that your information is exposed unnecessarily:

  1. Never send information you deem sensitive in an email body. Email is like a postcard sent via snail-mail - freely readable by anyone whose hands touches it in the delivery process.
  2. When sending information in email that is sensitive:
    1. if it's not already in a file format, save the information to a file (for example, using Microsoft Word, Notepad)
    2. encrypt the sensitive information.Some applications include their own password/encryption capabilities. To make the process easy and to keep secret even file information (like filenames and types), I recommend using a utility to create an encrypted archive.
    3. send the information as a file attachment to the email
    4. contact the recipient out of band (for example by phone) to inform them of the password to open the file. Do not send the password in the email body as that is like sending the keys to open the safe along with the safe itself.

Voila! You are now securely sharing information without exposing it to the rest of the world! You will never be sorry safeguarding your information on the internet - especially when you consider that technologies to help protect youself (like Sophos Free Encryption) are free.

Sophos provides a free encryption utility to encrypt and compress sensitive information. It can be used for free commercially and personally.
