The firewall doesn’t directly encrypt data, but it plays a vital role in data encryption to protect the confidentiality and integrity of data. Encryption is a data security technique whose core purpose is to convert readable data (plaintext) into an unreadable form (ciphertext) to prevent unauthorised persons from accessing or tampering with that data.

A VPN does encrypt your data, providing a secure channel for your online activities, but choosing a trustworthy provider is crucial. Understanding the encryption protocols and limitations of a VPN is essential for making informed choices about your online security and privacy.

Although encryption technology can protect the confidentiality of data, it cannot guarantee the integrity of data alone and has limitations. Data integrity refers to ensuring the reliability and consistency of data throughout its lifecycle, including capture, storage, retrieval, updating, backup and transmission.

While encryption may increase data size to some extent, the benefits it provides seems far outweigh this consideration. As technology advances, encryption methods are becoming more efficient, minimizing the impact on data size while maintaining robust security.
