Stealing company information and trade secrets is a well-known challenge that businesses strive to protect against. However, it can go undetected. As many times companies don't notice any abnormal network activity. We use cryptographic techniques to ensure confidentiality, integrity, and authentication of data whether in motion or at rest. Data is in motion while traveling through the network moving from place-to-place. Data is at rest while on a drive, cloud storage or removable media.
