VPN vs proxy
A proxy forwards some application traffic; a VPN typically protects the whole device path to a tunnel endpoint with encryption.
Proxy in one minute
An HTTP or SOCKS proxy accepts connections from an app and relays them. Only apps configured to use the proxy send traffic that way. Encryption to the proxy depends on the protocol (HTTPS proxies differ from plain HTTP proxies).
Browser extensions that “change your IP” are often proxies.
VPN in one minute
A VPN installs a virtual network interface and routes matching traffic through an encrypted tunnel—usually all apps unless you split-tunnel. See What is a VPN?.
Comparison table (mental model)
- Scope — proxy: per app; VPN: system-wide (typical)
- Encryption — proxy: optional/variable; VPN: core feature to the provider
- DNS — easy to get wrong with proxies; VPNs should force resolvers
- Kill switch — uncommon for proxies; expected for serious VPN clients
When a proxy is enough
Narrow cases: one browser, low stakes, you understand the trust model. For travel Wi‑Fi and whole-device protection, a VPN is the stronger default.
When available, Chrome’s authenticated proxy path in VeritasVPN is intentionally browser-scoped—different from the Android/Linux full-device tunnel. Read product docs so the mode matches the threat.
