Which feature of Sophos aids in data integrity during transmission?

Data integrity during transmission is primarily maintained through data encryption. This feature ensures that data is transformed into a secure format that can only be read or decrypted by authorized parties. When data is encrypted during transmission, it becomes unreadable to any unauthorized users or systems that might intercept it, thereby protecting it from tampering or unauthorized access.

The process of encryption employs algorithms and keys, ensuring that even if the data is intercepted, it cannot be deciphered without the appropriate key. This significantly enhances the security of data as it travels across networks, whether public or private, safeguarding sensitive information from being altered, replicated, or compromised.

While other features like network firewalls, malware scanning, and user authentication play important roles in overall security, they do not directly address data integrity during transmission in the same way that encryption does. Firewalls help to block unwanted traffic, malware scanning identifies and removes malicious content, and user authentication verifies user identity, but it is encryption that specifically focuses on securing the data itself and ensuring its integrity and confidentiality when moving from one point to another.
