Large-scale data breaches continue to expose the weaknesses in traditional information security strategies. Network and device protection is clearly not enough. Full-disk or volume encryption is a single-use-case approach that leaves information exposed at the data level. Persistent data-level encryption has become a necessity, especially in highly regulated industries. Files are compressed using PKWARE’s industry-best technology, reducing file sizes by up to 95%. Encrypted files can be shared and decrypted by authorized users on any enterprise operating platform. Sensitive data can be protected using a variety of methods, including password-based encryption and certificate-based encryption. Enables organization-wide control and consistent policy enforcement.
