Both Internet users and organizations can do that with the help of free encryption tools which can enhance protection by keeping valuable information hidden from malicious actors. According to “ The 2019 Global Encryption Trends Study” released by the Ponemon Institute, 45% of the organizations surveyed said they have an encryption policy in place to secure the most important data. At the same time, it’s a way that can be used to archive large amounts of data or to secure private communication over the Internet. Encryption helps you secure sensitive information from cyber criminals or other online threats and make access harder to them. The encryption process uses a key and an algorithm to transform the accessible data into an encoded piece of information that can only be deciphered by authorized persons. On a basic level, encryption is one of the best protection methods available to keep all your digital assets safe. Whether it’s personal or work-related, our data is always at risk of falling into the wrong hands, all the more reason to choose the best free encryption software.
