What is the difference between a VPN and a Proxy Server?

• A. A Proxy server hides an IP address; a VPN encrypts all data
• B. A VPN hides an IP address; a Proxy encrypts all data
• C. Both perform the same task
• D. A Proxy server encrypts only the header data

Answer: (A)

Understanding how traffic is secured and routed helps distinguish a VPN from a proxy. A proxy server hides your real IP by forwarding your requests through the proxy, so destinations see the proxy’s address instead of yours. But proxies don’t automatically encrypt your data; without encryption like HTTPS, someone on the network could read what you’re sending. A VPN, in contrast, creates an encrypted tunnel between your device and the VPN server, so all of your traffic is encrypted and appears to come from the VPN server. That means you get both IP masking and data encryption for essentially all apps and services, not just a single application. This is why the description that a proxy hides an IP address and a VPN encrypts all data is the most accurate general statement. The other options either misstate encryption, claim both do the same thing, or suggest only header data is encrypted, which doesn’t reflect how these tools typically work.
