9 Encrypted Email Services and Apps for Better Privacy

An email has been the harbinger for all types of communication in every business. No one can ignore or sacrifice the reliability, economy, and mobility of the messages received in their inboxes.

The first thing that pops to mind while speaking about email is popular services like Gmail, Yahoo, and Outlook. While they all are great for sending and receiving web messages, they have a common drawback.

They don’t provide end-to-end encryption to protect messages in transit.

It’s not a significant problem with any casual messages you send. However, the problem arises if your communication includes sensitive information like social security, credit card, account numbers, or other top-secret company data.

Why?

It’s because all it takes is a single slick to expose this sensitive information. This is why email encryption is so important and should be a part of your business security plans. Sending a secure email is different than anonymous emails.

What exactly is email encryption?

Email encrypting is nothing but the conversion of email messages into a secret code to prevent unauthorized access and better privacy. It’s done to protect your sensitive content from being read by other entities except for the intended recipient. It may include authentication.

It’s necessary because most messages are transmitted in a clear form. There is a chance of other people than the designated recipient using specific tools to read its contents. You can understand its implications better if you picture it as an algorithm poking and prodding through your sensitive data like love notes and doctor appointments!

Email encrypting uses public-key cryptography, where users use a public key to code messages. They, however, keep and use a secret private key to decrypt the messages. Private keys digitally encrypt and sign messages before sending them.

Benefits of email encryption

Now you know the importance, read the following main benefits.

Protects private information

With so much private, sensitive and secret information exchanged over messages, only the intended recipient must see it. Remember, even your ‘secret password and username’ can be easily accessed and stolen by hackers.

An email encrypting server prevents hackers from decrypting this secret information and misusing it.

Affordable security

There is no need to buy any additional software or hardware. There are so many services that can be trusted to secure your information at a cost-effective rate.

Follows regulations

Many industries have rules to be followed when it comes to communication. For example, a patient’s information should be kept confidential and not shared without the patient’s consent. So a hacker getting hold of the information will be considered a violation. Encrypting emails helps prevent these documents from falling into the wrong hands.

Now that you know their benefits and why you should use them instead of standard providers like Gmail, you naturally want to know more about the available options.
