How Important is Email Encryption TodayEmail encryption protects the contents of the email from being stolen and exploited, which can damage the business and its stakeholders.

FREMONT, CA: With each passing day in this increasingly digitized world, the business environment depends far less on traditional solutions. What companies now refer to as "snail mail" was originally the only means of officially written communication. For critical communications, almost every company now uses email. As it has always been vital to secure physical mail, several different types of email encryption for security purposes have also become essential for every company.

What is Email Encryption?

Email encryption is a form of advanced cybersecurity. It applies cryptographic technology to secure communications in the digital age and cryptography functions by forming a secret code. Unlike old passwords, this code is unbreakable by humans. At the very least, without the necessary access. Encryption is critical for keeping confidential emails and the business safe.

What Types of Email Security Are There?

Encryption is a method of protecting email if it has been hacked and is in the hands of someone who isn't meant to have it, whether through theft or carelessness. But there is security in place to ensure that emails do not reach cybercriminals or other individuals who must not be reading them.

Gateway, encryption, and authentication are three of the most prevalent and valuable types of email security.

Gateways and authentication are two methods for mitigating email theft. Encryption is the most crucial and significant of these three components. But without encryption, every email that is captured or hacked becomes a security risk immediately. The hackers may not be able to read the stolen emails if encryption is activated.

Types of Encryption Security for Email

Encryption is a field that is both difficult and dynamic. It needs to be complicated because it is based on the incapability of humans to decipher the encryption codes. But the fundamentals of how encryption works can be broken down into a few simple parameters.

There are only two basic types of email encryption. These are then divided into numerous tools or protocols that are similar but not identical. The following are the two primary categories:

Transport level encryption – The contents of emails are encrypted during transit among the sender and receiver, but not essentially before or after. This type of encryption is less secure, but it is often less expensive.

End-to-end encryption – At the endpoints, the contents of the emails are secured. Every outgoing email is encrypted whenever it leaves the sender's workstation and is only unencrypted when it reaches the recipient's computer. This is the more reliable alternative, but the greater security it provides usually comes at a higher cost.

Email encryption secures the contents of the email from being stolen and exploited for damaging the business or its stakeholders. The content may include email text, media content, and even critical metadata that isn't visible to the naked eye.
