Email communication contains a large amount of sensitive data which can be accessed when emails are sent and received. It is a big problem that cannot be put on a back burner by any business.

The solution to this problem is email encryption services. Let’s see how email encryption works to protect your data and privacy.

What Is Email Encryption and How It Works?

Information sent through email is vulnerable to becoming compromised. Without email encryption, hackers can intercept email and read its contents. This also includes documents with sensitive information. Once the hackers get access to your email communication, the prying eyes can also follow back to your network.

Email encryption works like a lock with two keys. When you encrypt your email, only the person with private and public keys can access and read the mail contents. Even if the hacker gets hold of your sensitive email, he/she would not be able to access the contents in absence of the keys.

The keys used by email encryption services are extremely complex. They use advanced encryption logarithms like the AES which offers varied key lengths like 128, 192, and 256 bits. Even the fastest supercomputer existing today will take billion years to decode a 128-bit key.

How Email Encryption Protects Your Data and Privacy?

Email encryption solutions are offered in different forms – desktop email encryption and gateway email encryption. In desktop email encryption the email is the system automatically encrypts, decrypts, digitally signs, and verifies message as per centrally managed policies. In this email encryption model, the email message is secured before it leaves the internal network or stored in the cloud.

In gateway email encryption, there is no software installed at the client end. Instead, the email encryption solution resides on the gateway between the internal network and the public Internet. Gateway email encryption solution ensures the data is protected in transit when being transmitted over the public internet.

Gateway email encryption solution also ensures that the data and privacy aspect of the email communication is protected when the email message is at rest on a recipient email server. In gateway email encryption solution, businesses can also enable automated encryption on common filtering flags like social security numbers or credit card information.

Advantages of Email Encryption Solution

The email encryption service is delivered end-to-end with an easy-to-use interface to employees. The email encryption management server automates provisioning, deployments, policy enforcement, and key management. Businesses using email encryption solutions have full control over the procedures and policies through a simple web-based management console.

Every organization has data to protect. Email encryption services allow the organization to realize the benefits of email communication minus the risks associated with it. If you are large enterprise having treasures of intellectual property in an email, it is time to use email encryption before someone with terrible motives get hold of it.
