Emails are one of the secure ways to communicate professionally. Yet, is it one hundred percent secure?
No, at least not, unless and until you set up an email encryption system. There are high chances that any unauthorized person couldn’t access your mail without encryption.
After all, you don’t want the whole world to see what you are sending. And since we are mentioning professional conversations, many emails have confidential information that should stay inside the company only. For example, it can have a check to pay bills or some sort of extremely important credentials and whatnot.
Now that you have got an idea why we are emphasizing encrypting your emails, let’s have a look at the topic from scratch. This article has got you covered with details, including what email encryption is, why it is beneficial, and some of the best email encryption services you can opt for. Stick till the end to find out!
What is Email Encryption?
Email encryption is a way to secure confidential information from being accessed by an unauthorized person. Email encryption helps to protect sensitive data. With encryption, the emails are converted into some code language that could only be read or decrypted by the intended reader. Apart from the potential sender and intended receiver, no other person could read the message.
It also requires the authentication procedure for the decryption of the message. Without encryption, most of the information we use to send emails is prone to hackers. These hackers can gain access to our important information like login details, bank account details, etc., apart from these. They can hack the whole email account of the person and use it for illegal purposes.
Email encryption ensures that the information sent over emails starts from the source and reaches the destination without interruption. Even if someone hampers with the message, he will not be able to get the content in the email. Because of all these reasons, it is very important to have email encryption services installed on our devices. With email encryption, anyone from the sender to and receiver would only get a jumbled set of words or characters.
Email encryption can be of the following types:
- Pretty Good Privacy(PGP) This email encryption was invented around 1991. It is used to encrypt emails as well as files. PGP uses a set of key pairs to encrypt and decrypt the data of the emails. This was initially freeware and gained popularity among users.
- Secure Multipurpose Internet Mail Extension(S/MIME) This email encryption service was developed by RSA Data Security, and today it is used by most users as advanced email securing software.
- Transport Layer Security(TLS) It is a kind of protocol to protect the data sent over any network. This protocol is very much in use for the encryption and decryption of information on the web.
How Does Encryption Protect Email?
Encryption can protect emails by two methods. Emails can be secured while they are in the sending process. Apart from this, they can be secured from the sender and receiver sides. To protect the email in transit, email service providers make use of Transport Layer Security.
With TLS, the communication of emails becomes secure, and attackers and hackers cannot peep into the sensitive information. When the emails are in the process of sending, TLS makes the passage secure and safe so that any unauthorized person can read no information in between.
Even if the passage is secure, hackers can still get to the message from the users’ end. Hence, end-to-end safety is also required for complete security. For this purpose, PGP and S/MIME protocols are used. These help to transfer messages securely over the network.
They do so by making the message unreadable by candidates other than the authorized users at both ends. The service converts the message into code at the sender’s end. Only at the receiver’s end does the message get decoded. This whole system of protecting the data is what we call an end-to-end encryption method.
Benefits of Using Email Encryption
Email encryption is necessary to secure the emails sent over the network. It becomes more important when we use a public network or any open Wi-Fi service. Email encryption provides us with lots of benefits, some of which are given below:
- Security of sensitive information With the help of email encryption, we can secure our sensitive information. We use emails for sending important details like company secrets, legal papers, personal details, information about the assets of the company, and many more. An unencrypted message is prone to cyber-attacks. So, emails are required to be encrypted to avoid any leakage of sensitive information. Data will not be compromised with the use of email encryption.
- Authenticity Email encryption will help the sender and receiver to identify each other. The use of digital signatures can further confirm that the information is untouched by any unauthorized source. If we talk about a whole organization, this email encryption service can prevent any malicious activity from attacking the organization’s whole system. It will prevent it from corrupting anything in the system.
- Cost-saving Email encryption can also prove cost-effective. If the companies only use it on the email platform, then users or employees would not need to install another email encryption software. This would save the overall cost.
- Prevents risks With the help of email encryption, business risks can be prevented. Any useful information traveling within the organization, like trade secrets, new project details, etc., can be secured.
