Best Encryption Software & Tools for 2021

Enterprises invest in state-of-the-art threat defenses like next-gen firewalls, microsegmentation and zero trust tools. However, even the very best tools in these categories assume that data breaches happen and aim to limit the damage. Sending and receiving data is one element that creates the potential for data breaches because attackers can intercept data transfers.

Once attackers gain access to a network or data in transit, the best course of action to protect sensitive information is to make it indecipherable. Encryption software protects data in motion and data at rest. Data secured with encryption can only be accessed using a password, thus adding an extra, vital layer of security.

Best encryption tools & software

This list contains both traditional encryption products that offer file encryption for data in motion and at rest, as well as newer quantum cryptography tools. Modern encryption algorithms require so much processing power to break that they’re virtually hacker-proof. But with the advent of powerful quantum computing, this may no longer be the case.

Quantum cryptography, also called quantum encryption, applies the principles of quantum mechanic’s fluid states to solve substantially more problems with the same processing speed to keep up with hackers using quantum computing. If you want to prepare for the future, quantum cryptography could be a good option for you.

What is data encryption?

Encryption software scrambles readable data using algorithms in encryption keys and turns it into an encoded piece of information. Public encryption keys are used to initially scramble and secure the information. A private key held by an authorized user is then used to decrypt the data and return it to a readable format. Modern encryption keys abide by the Advanced Encryption Standard (AES) that uses 128-bit and 256-bit key lengths, which are extremely long strings of numbers, to scramble information. In some cases, even 4096-bit key lengths are used.

Homomorphic encryption

Encryption helps ensure that data stored and in transit (at rest and in motion) remains secure and indecipherable but eventually, that information will need to be accessed. This opens the window for hackers to find and steal that information. Homomorphic encryption was developed to allow computation on encrypted data in use so it remains confidential while some tasks can be carried out. This can be helpful for added security but not all tasks can be completed when working with homomorphically encrypted data.

Benefits of encryption software

All organizations must store and transmit data, such as personally identifiable information (PII) or financial data. This is especially true for the massive amounts of data managed by enterprise organizations. Encryption is critical for protecting information that’s exposed when other security software on the front lines fails.

Data encryption is not only helpful in protecting sensitive information but also helps reduce the chance of expensive legal fees and damage to an organization’s reputation. Without proper security measures in place, including encryption, organizations risk coming under fire for not complying with data privacy regulations, such as the EU’s General Data Protection Regulation (GDPR) and the California Consumer Privacy Act (CCPA).

File encryption vs. full-disk encryption

It’s important to know the distinction between file encryption and full-disk encryption to avoid leaving holes in your security infrastructure. Full-disk encryption is useful for securing individual devices. Its use cases are limited as it can’t encrypt data being sent from or received by that device.

File encryption is a more comprehensive solution. It can encrypt all individual files and pieces of data stored on a device or on a server, as well as encrypt data in transit.

Both full-disk encryption and file encryption have their applications. Which is best for your organization depends on your security needs. This list includes both types of encryption products.

What to look for in encryption software

There are a few key features to look for when shopping for an encryption solution. Password strength indicators should be a priority. Far too many employees use the same simple, easy-to-remember passwords for almost everything. Password strength indicators will help reduce any vulnerabilities caused by weak passwords.

Password management capabilities can also assist with this by securely storing and inputting passwords automatically so that every employee can have long, complicated passwords without needing to remember them. Also, look for virtual document shredding functions. This will ensure that any data that is deleted is actually eradicated and can’t be scraped from your disk.

Encryption best practices

Encryption may be one of the most powerful tools in your security architecture, but it is not a stand-alone solution. It should still be combined with other solutions, such as antivirus software, firewalls and VPN services to cover all endpoints.

After encrypting or copying a version of a file, the original unencrypted version should always be completely wiped from your system. The data may still exist on the disk even after it’s been deleted and can be recovered using specialized tools. Using a virtual shredder or secure deletion feature will ensure it’s completely wiped.
