Encryption The primary purpose of encryption is to protect the confidentiality of digital data stored on computer systems or transmitted via the Internet or other computer networks. Modern encryption algorithms play a vital role in the security assurance of IT systems and communications as they can provide not only confidentiality, but also the following key elements of security: Authentication: the origin of a message can be verified. Integrity: proof that the contents of a message have not been changed since it was sent. Non-repudiation: the sender of a message cannot deny sending the message. Data protection solutions for data encryption can provide encryption of devices, email, and data itself. In many cases, these encryption functionalities are also met with control capabilities for devices, email, and data. Email control and encryption is another critical component of a data loss prevention solution. Secure, encrypted email is the only answer for regulatory compliance, a remote workforce, BYOD, and project outsourcing. Premier data loss prevention solutions allow your employees to continue to work and collaborate through email while the software and tools proactively tag, classify, and encrypt sensitive data in emails and attachments. The best data loss prevention solutions automatically warn, block, and encrypt sensitive information based on message content and context, such as user, data class, and recipient.
