The technology that allows for the secure transfer of data across public networks is known as encryption. By converting data into an unreadable format unless a decryption key is provided, encryption ensures that sensitive information remains confidential during transmission. Protocols such as SSL/TLS are commonly used to secure web transactions and communications. As businesses increasingly rely on cloud services and remote work, the importance of secure data transfer technologies has grown, protecting personal and corporate data from unauthorized access and potential breaches.
