10 Best Free Encryption Software for 2024

February 27, 2024

free encryption software

There’s a lot of sensitive and personal data on the internet.

From social security numbers to home addresses, keeping this data safe and secure doesn’t need to break the bank. There are free encryption tools that keep all types of data secure and away from prying eyes without being too costly or causing companies to go over budget.

On its most basic level, encryption transforms information into code that can only be deciphered by authorized individuals or parties. It helps users remain confident their information is safe no matter where it’s stored.

Encryption can be used to disguise data both at rest and in transit. Data at rest is usually stored on a hard drive or a USB. Data in transit refers to information being transferred across internet, telephone, or intercom networks.

Best free encryption software

Encryption software uses cryptography to protect the confidentiality and integrity of data. Companies rely on these tools to ensure that only specific parties can access certain types of data and to reduce their liability if they’re part of a breach or security leak. Encryption software takes standard information and turns it into scrambled, unintelligible data.

The list below contains reviews by actual users from the best encryption software category page. It’s important to note that in the context of this list, vendors and software that offer a free trial are also considered to be free. To be included in this category, a solution must:

  • Ensure data and files are secure using ciphertext
  • Prepare data at rest, data in transit, or data in use for encryption
  • Allow users to choose and manage files and their encryption settings

*This list is based on G2 data collected on February 5, 2024. Some reviews may have been edited for clarity.

1. MOVEit

MOVEit by Progress helps organizations meet strict cybersecurity compliance standards such as PCI-DSS, HIPAA, GDPR, and SOC2. This encryption tool provides a secure environment for sensitive files, while easily ensuring the reliability of core business processes. It offers the security, centralized access controls, file encryption, and activity tracking needed to guarantee operational reliability and compliance.

Users can get started with MOVEit with a 30-day free trial.

What users like best:

“It can be helpful in reaching your business goals. Although it still needs polishing, it is a tool that helps you keep your files safe with secure encryption. Overall, I definitely recommend using MOVEit to all peers working with FTP that need to keep their data safe!”

- MOVEit Review, Monica N.

What users dislike:

“We are not able to look for the files based on the date. That seems to be one issue. Another is setting up a server is a bit difficult. You need to consult the admin team. Specifically, a Microsoft Server operating system to get the MOVEit installed.”

- MOVEit Review, Raj T.

2. Tresorit

Tresorit is an end-to-end encrypted, zero-knowledge content collaboration platform that lets security-conscious companies manage, sync, sign, and share their files safely.

Tresorit provides a 14-day free trial for new users..

What users like best:

“One of the main aspects of Tresorit is its robust encryption, which offers end-to-end encryption for files kept on their servers. This indicates that even if Tresorit wanted to, they cannot access the user's files; only the user has access to them. Also, its user-friendly interface makes it simple to upload, download, and share data securely.”

- Tresorit Review, Deepak J.

What users dislike:

“Reorganizing files is a pain. Much more cumbersome and visually un-intuitive than Windows File Manager. Renaming. You have to click, wait, click, wait, and often it never works. Moving files you have to go all the way up the directory and into the subfolder, sub folder, etc., which shouldn't really be necessary. You also can't open more than one window, which further necessitates following Tresorit's built in path.”

- Tresorit Review, Rosi H.

3. ESET Protect Advanced

ESET Protect Advanced offers endpoint protection against ransomware and zero-day threats, backed up by powerful data security. It boasts full-disk encryption, advanced threat defense, and server security, making it a comprehensive security solution for all business sizes.

What users like best:

“It's simple to deploy. It gives me the flexibility to deploy via Intune, which is vital for managing my device fleet. Knowing I can manage everything from an easy to understand dashboard also gives me peace of mind.”

- ESET Protect Advanced Review, Naved P.

What users dislike:

“Needs to be more visible to the end user if there's a problem with the installation, service operation, updates, etc. There should be regular pop ups to notify the user that intervention is required.”

- ESET Protect Advanced Review, Steven S.

4. HashiCorp Vault

- NordLocker Review, Christina P.

What users dislike:

“Users do not get informed when new files are uploaded. Everything was pretty much fine, just some of the folders couldn't load because of symbols in the folder name..”

- NordLocker Review, Verified User in Investment Banking

- Heimdal Review, Jeremiah E.

- AES Drive Review, Verified User in Information Technology and Services

What users dislike:

“Sometimes it's a little bit too secure and I know that might not make sense, but if I was to ever lose or forget my password I would have a pretty hard time looking at encrypted files.”

- AES Drive Review, Verified User in Computer Software

- DropSecure Review, Charles G.
