What is a VPN and when would a business use one?

• A. A Virtual Private Network; to securely connect remote users or offices to the corporate network over the internet
• B. A Public Video Network for streaming
• C. A Virtual Processing Node for high-performance computing
• D. A Visual Project Navigator for team collaboration

Answer: (A)

A VPN, or Virtual Private Network, creates a secure, encrypted tunnel over a public network so data between remote users or branch offices and the company network stays private. Businesses use VPNs to give employees working remotely and geographically dispersed offices access to internal systems, apps, and files as if they were directly connected to the corporate network. This enables secure connectivity, protecting confidentiality and integrity of data in transit while using the public internet. The other terms describe different technologies (video streaming, high‑performance computing, or collaboration tools) and don’t provide secure remote access to a private network.
