Why is data encryption necessary?

The purpose of data encryption is to maintain the confidentiality of your data regardless of whether it is in storage devices, on computer systems, or while being transmitted through public or private networks.

So long as your data is well encrypted, any cybercriminal who manages to get past your IT security and steal your data won’t be able to decipher it, rendering their loot useless. 

With ever-increasing transmission of and access to data over the open internet, it’s more important than ever to ensure critical business data is encrypted in transit and while at rest.     

Additionally, some key reasons your organization needs to ensure your data is appropriately encrypted include:

Data Privacy

With encryption, no unauthorized personnel will be able to read data or communications in a given system unless they are the intended recipient or owner of the data. 


It makes it difficult to deny the validity of a message’s integrity and authenticity.

Data Security

Regardless of whether your data is in transit, at rest, or in storage, encryption will help prevent data breaches.

Data Authentication

Data authentication allows the original location of a message to be verified and can be achieved with public-key encryption, ensuring that the owner of a site is the valid owner and has the private key listed in the website’s TLS certificate. 

Data Integrity

Data encryption also helps maintain data integrity by preventing on-path attacks, among other things. This type of protection assures that the person receiving the transmitted data hasn’t been tampered with while in transit.

Data Regulations

Many industry and government regulations require organizations to encrypt data to protect their customers’ private data adequately. 

In this way, following data encryption best practices can help your company maintain compliance with something like payment card industry (PCI) compliance and Health Insurance Portability and Accountability Act (HIPAA) compliance

Challenges facing modern data encryption

The challenges to data encryption are ever-changing as cybercriminals continue to adapt to modern data security practices.

The most basic and common form of attack against encryptions is brute force, where the attacker tries to enter random keys/passwords until the correct one is found. Brute force attacks almost always rely on automation; otherwise, they’d be too time-consuming.

Alternative methods for breaching encryption securities include cryptanalysis. The attacker hunts for a weak spot in the cipher and then exploits it, and side-channel attacks, where the attacker aims to sabotage the implementation of the encryption itself.

Best encryption software programs

There are three main types of data encryption software programs, all of which are explored below with examples your business can consider using. 

Full Disk Encryption

Also known as whole disk encryption, this secures data that’s considered “at rest” in devices like your computer or phone. This type of encryption can prevent unauthorized users—even the device makers—from accessing data stored on their disks. 

Encrypted File Sharing

Also known as encrypted file transfer, this protects files in transit from one system or device and another. Even if a cybercriminal can intercept the file, the encryption will prevent them from accessing its contents. 

Email Encryption

This involves encrypting email messages and attachments so that only intended recipients can read and understand their content. A good email encryption solution should simplify the encryption process and not interrupt the email service user experience.   

Egress Intelligent Email Security — Corporate email security platform utilizes contextual machine learning, encryption, and analytics tech to secure your data. It’s designed to prevent human-generated data breaches from both within and outside your organization, secure sensitive data, and helps identify areas of risk across your business’s email network.

Encryption is only one part of your IT security

While utilizing encryption programs is excellent for improving your organization’s IT security, it’s important to remember that it’s only one piece of a complete IT security plan. 

Your business should have rules, policies, and protocols in place for handling critical data in a variety of situations, whether your employees are on-premise, working from home, or are fully remote. 

In summary: 

Using data encryption to protect your business’s private data

Many individual users need little more than standalone encryption solutions to sufficiently secure their system and device data. Still, SMBs and larger organizations have to think about encryption with their entire IT security strategy in mind. 

A good encryption solution should integrate with your systems seamlessly so that it doesn’t take up much mental space, if any; you shouldn’t have to “enter a password” every single time you want to access encrypted data. Such solutions might secure data, but they’re a pain to use. 

If tackling data encryption seems too daunting to get a handle on, don’t worry. It doesn’t need to be something your organization handles on its own—the same goes for all your IT security needs.
