Encrypting or decrypting large volumes of data can slow down system performance. IT professionals can minimize this impact without exposing their devices to any security risks. If you want optimum protection without sacrificing efficiency, encryption software will serve you right.

Encryption tools can prevent unauthorized access to your business's digital information by facilitating data encryption and decryption. Luckily, you can explore a free encryption solution to explore software functionalities without investing upfront. 

This article highlights, in alphabetical order, the three top-rated free encryption software products based on verified software reviews. Read more.

While the products mentioned belong to different categories—core encryption, password management, and cybersecurity, the common encryption features across all these tools include data security, file encryption, and secure data storage.

1. Bitwarden

Bitwarden is an open source password management solution that encrypts and/or hashes your data on your local device before sending it for cloud storage. Bitwarden servers store encrypted data only. It is a zero-knowledge encryption tool, which means that only the user has access to the master password key that is used to decrypt vault data. 

Bitwarden’s free version offers basic two-factor authentication (2FA). If you need advanced 2FA to log in via multiple methods, such as Duo Security, YubiKey, and FIDO2 Web Authentication, you can invest in the premium version.

Free features:

  • AES 256 encryption: Protect sensitive data using advanced encryption standard-cipher block chaining (AES-CBC) encryption, offered by the system for vault data. AES-CBC divides data into blocks and encrypts each block with an AES-256 encryption key.

  • Local data encryption: Ensure data privacy and enhanced security as your device’s stored data is encrypted locally before it is synchronized with Bitwarden’s servers. This ensures that even if your data is intercepted during transmission, it remains inaccessible without the master password. 

  • Two-factor authentication: Add an additional protection layer to your account using the 2FA methods supported by the tool. These include a two-step login via an authenticator app, such as Google Authenticator, and an email for free users.  

Customer support options: Email, online help center, and knowledge base.

Who should consider Bitwarden?

IT technicians wanting a free encryption tool to help them securely review and audit the source code can consider Bitwarden. The open source software’s source code is available on GitHub under the GNU Affero General Public License (GNU AGPL) based on the GNU GPL version 3. Hence, encryption users can easily examine the source code, and verify security and encryption implementations.

Outline your security needs before considering a free encryption platform. Determine the data types (financial records, customers’ information, personal files, etc.) you need to protect. Then, evaluate your data’s sensitivity to prioritize the level of security features and encryption you require from a free tool.

2. Cypherdog Encryption

Cypherdog Encryption is a core encryption platform based on asymmetric encryption that uses a pair of keys to encrypt and decrypt files in any text or file, regardless of their size and format. This encryption tool allows users to share files by any medium, including email or other platforms like Google Drive, WeTransfer, and Dropbox. Cypherdog users can share emails supported by the tool’s Chrome, Edge, and Firefox plugins for Gmail, Outlook, and Thunderbird add-ins.

The software’s free plan offers email encryption for a limited period, i.e. up to 14 days only. After this time frame, the version supports the decryption function only. To access the advanced encryption package, you need to upgrade to the paid plan. 

Free features:

  • Message encryption and decryption: Encrypt and decrypt email messages, texts, files, and attachments with a single click. While encryption transforms the original message into an unreadable form, decryption reverses the process to restore the original message into a readable form. 

  • End-to-end encryption: Ensure that the data you send or receive is encrypted from the moment it is sent until it is received by the recipient. This ensures the confidentiality of the information being shared. 

  • Email aliases: Add an additional email address that can be used for different purposes, such as receiving emails without creating a separate email account. Email aliases can help filter out spam, protecting your account from phishing attacks. Instead of setting up a new email account, aliases are created within an existing email account and are linked to the primary email address. 

Customer support options: Live chat, online FAQs, and knowledge base.

Who should consider Cypherdog?

IT professionals looking to prioritize the security and privacy of data while sharing files can consider Cypherdog. The software allows users, to securely send, manage, and store files in all sizes and formats, using end-to-end encryption. This ensures that no third party, including trusted third parties have access to your files. The tool supports general data protection regulations (GDPR), network and information security (NIS), the digital operational resilience act (DORA), and other implementations and regulations.
