Encrypted Files

6 Best Free and Open Source Linux File Encryption Tools

The importance of security should never be underestimated. The consequences of losing data can be disastrous for any organization. For example, the loss of a single unencrypted laptop may have huge repercussions. This could include breaching data protection legislation with the risk of a significant fine, a loss in the confidence of an organization, as well as the risk that sensitive data may fall into the hands of a competitor or third party with malicious intent.

Of course, whenever information is accessible, there is the risk of its loss. A misdirected fax or a misdelivered letter can lead to sensitive information being disclosed in error. But the severity and ramifications of that risk is exacerbated when the data is stored on a computer. Modern computer hard disks have the capacity to store a gargantuan amount of data. A single hard disk may hold personal details of hundreds of thousands or even millions of individuals. In the event that the data is not encrypted, the loss of the hard disk may represent an organization’s worst nightmare. The actual cost of replacing the hard disk of the machine pales into insignificance compared to the loss of the confidential information and customer security.

This roundup looks at the finest GUI-based file encryption tools. We’ll be covering command-line tools in a separate roundup. If you’re look for tools that encrypt a whole disk, head over to this roundup.
