Best Encryption Tools & Software for 2021

Enterprises can invest in state of the art threat defenses like next-gen firewalls, microsegmentation and zero trust tools, but even the very best tools assume that data breaches happen and aim to limit the damage. And sending and receiving data creates the potential for even further vulnerabilities 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. This is done with encryption software that protects information stored, received and sent. Data secured with encryption can only be accessed using a password, adding an extra, vital layer of security.

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 fail.

Data encryption is not only helpful in protecting sensitive information but also helps reduce the chance of expensive legal fees and a shot 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 glaring 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.

Best encryption tools & software

This list contains both traditional encryption products 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 a much higher number of 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.

IBM Guardium is available by subscription and is best suited for enterprise companies who want an all-in-one solution for data security.

See our in-depth look at IBM Guardium Data Encryption.

AxCrypt Premium

AxCrypt Premium may not be as robust as competitors but it is a powerful solution for smaller organizations that don’t have the resources to support more comprehensive solutions. It can support both 128-bit and 256-bit AES encryption and files can be conveniently accessed through a mobile app.

This is also a good option for cloud-based networks. Axcrypt Premium automatically encrypts files saved on cloud services like Google Drive, AWS and Dropbox. A free version is available but unless you’re an individual looking to secure a home computer, it likely will be too limited to serve a business’s security needs.


VeraCrypt is a popular option in the enterprise-grade encryption market for Windows, macOS and Linux operating systems. It automatically encrypts data and creates partitions in your network based on volume size, location and specified hashing algorithms. This makes it an easy-to-implement solution for organizations looking for a more hands-off approach.

VeraCrypt is an open source program. This can sometimes be an issue as corporate products typically receive more regular updates than open source alternatives. But VeraCrypt has a strong following of advocates and is constantly being improved with new security enhancements. The basic version of VeraCrypt is free and strong enough to serve some organization’s needs.

CertainSafe Digital Safety Deposit Box

CertainSafe Digital Safety Deposit Box is another good option for cloud-based systems with a focus on regulatory compliance. This completely cloud-based software tool stores all of your information in the cloud and is completely focused on securing it. It provides standard file encryption as well as encrypted correspondence capabilities. This allows team members to collaborate and communicate directly through the tool under an encrypted umbrella.

One of its most exciting features is called MicroEncryption. After data is encrypted, CertainSafe then divides it into segments and stores them across multiple different servers. This is similar to using microsegmentation to protect lateral traffic across a network. Even if a hacker can gain access to one store of encrypted data, they still won’t have the whole picture as the rest is stored on different servers.


NordLocker is a relatively new encryption tool in the space but it was developed by a cybersecurity heavyweight, NordVPN. It provides 256-bit AES encryption, which is enough to secure most data, but where it shines is the inclusion of 4096-bit encryption. If 256-bit doesn’t quite give you peace of mind, 4096-bit surely will.

Users also appreciate the intuitive user interface. Adding or removing individual files from NordLocker is as simple as drag-and-drop. This should free up plenty of time for IT teams to work on other projects. NordLocker is available for both macOS and Windows.

Kruptos 2

Kruptos 2 is a suite of encryption tools that specializes in providing AES 256-bit encryption across a network using multiple operating systems, specifically Windows, Mac and Android. It’s also built to encrypt files across a wide variety of platforms, including mobile devices, portable storage and cloud-based services.

Kruptos 2 also comes with some helpful features like a strong password generator so there’s no worry of insecure passwords used throughout an organization. There’s also a virtual file shredder so any information that needs to be deleted is completely wiped from the disk. Kruptos 2 is available as a one-time purchase license rather than a subscription, so you only need to pay once. Single operating system licenses start at $39.95, but to get the full cross-platform experience, the bundle comes in at $64.95.


If your organization primarily employs cloud storage over on-premises, then Boxcryptor was designed for you. Boxcryptor provides a combination of AES and RSA (Rivest–Shamir–Adleman) end-to-end encryption for 30 different cloud services. Some of the key services include Google Drive, Microsoft and Dropbox.

The company refers to itself as a “zero-knowledge provider,” essentially meaning they streamline the implementation of encryption across multiple services and devices. There’s no need to be an encryption expert to deploy and manage Boxcryptor. Business subscriptions are available for $96 a year.


Some may already be familiar with 7-Zip as an archive utility tool but it offers much more than that. 7-Zip compresses files to reduce storage space and increase transmission speed. Additionally, it offers powerful encryption for data stored and in transit. Part of what makes it an accessible option is its simplicity. But if you’re looking for a product with a lot of additional features, you won’t find many here.

7-Zip may not have the scale to encompass enterprise encryption use-cases but it is a solid and easy-to-use option for smaller organizations. It was originally built for Windows but is also available on macOS and Linux systems. It’s also completely free to use.

Quantum Numbers Corp QNG2

Quantum Numbers Corp’s QNG2 is a Quantum Random Number Generator (QRNG) and is the first quantum cryptography product on our list. Its innovative quantum tunneling solution creates a sequence of truly random numbers that traditional encryption solutions are incapable of and can’t even be deciphered by hackers using quantum computing themselves.

QRNG also comes with an alert system that notifies you of any attempts to intercept incoming or outgoing communications. Quantum Numbers Corp’s encryption solution offers high speed of encryption, true randomness and on-demand scalability at a relatively low cost compared to other quantum cryptography solutions.

KETS Quantum Key Distribution

KETS’s Quantum Key Distribution product is able to encrypt stored data like other platforms but its main focus is on securing data in transit and correspondences. Its key distribution chip integrates into communication systems to secure transmitted data. It constantly and automatically changes encryption keys as data is being communicated in a one-time block cipher mode.

Its focus may be on secure communications but it still delivers on quantum-secure stored data with powerful encryption. KET Quantum Key Distribution’s chip defends against malevolent third parties, conventional hacks and quantum attacks.

Check Point Full Disk Encryption Software Blade

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.
