Security has become more important as people have begun to use their computers for more things. Many people use their email at work as well as at home. Cellphones and mobile devices now have the ability to surf the internet and check and send email. More and more purchases and other transactions are made online. This is all very convenient, but it can create security risks.
Many of your personal email messages probably aren’t of much interest to people other than the recipient, but you might want to keep others from snooping, anyway. If you send someone identifying personal information like your full name and address, you might want to consider using encryption. Even if the chances of it being intercepted are fairly low, it’s not a risk that you should take. Crimes like fraud and identity theft have become more common in recent years, and one reason is that people may have become more lax when they are sharing private information online, as well as just using the internet to do more things.
Regular email can be intercepted by other people, especially if you are on a public, shared network, or if your wireless network is not password protected. Even if you password protect your wireless connection, it may still be possible for others to access your email messages. Using email encryption gives you added protection from anyone who may be snooping in your private email or accessing your messages over a wireless network.
These types of services offer many options, with different ways of sending secure email (on their website, using your webmail, or downloading software for use with Outlook), as well as options that allow you to limit the number of times a message can be read, or to put an expiration date on the message. Secure email gives you more control over the email than regular email offers, and it provides added security whenever you are sending something you don’t want unauthorized people to see. When you want to send a secure message, you just need to decide what portion of the message should be encrypted, decide on a password, and share it with the recipient, who will use the password to unencrypt the email.
