What is the main purpose of a VPN in cybersecurity?

Encrypt data
Backup data
Restore data
Monitor network traffic

The correct answer is: Encrypt data

The main purpose of a Virtual Private Network (VPN) in cybersecurity is to encrypt data. A VPN creates a secure and private tunnel over the internet that protects the data being transmitted between a user's device and the VPN server. This encryption process ensures that any data exchanged is unintelligible to unauthorized third parties, thus enhancing privacy and security. Using a VPN also helps in establishing a secure connection when accessing public networks, making it difficult for attackers to intercept or read sensitive information such as passwords, financial details, or personal communications. By encrypting the data, a VPN protects it from eavesdropping and potential data breaches, which are critical aspects of safeguarding personal information and maintaining confidentiality online.
