Electronic Document Encryption (EDE)
Cyber Serval EDE (Enhanced Electronic Document Encryption) focuses on the fundamental security of data assets. Utilizing advanced kernel-level driver encryption, we ensure that core documents remain protected throughout their entire lifecycle—from creation and distribution to external sharing, and even in the event of unauthorized loss.
