The fundamental purpose of encryption is to protect sensitive information being seen by those with unauthorized access. Encrypting communications helps you maintain data confidentiality during transmission and storage.
This is especially important to people and organizations whose private data is particularly sensitive or confidential, such as banks, healthcare providers, military organizations, power and energy companies, and insurance providers.
Data encryption allows these types of organizations to hold onto personal information in a secure way that will not compromise your identity. Regular individuals may want to protect their information, too.
Encryption prevents your information from being tampered with. In a digital age that lacks trust, encryption can make you feel more secure that the information you send and receive is authentic. Improving data integrity and authenticity is another of encryption’s core benefits.
