What is the difference between a proxy and a VPN?

A proxy forwards traffic from one app or browser through another server, usually without encrypting it. A VPN encrypts all traffic from your whole device and sends it through a tunnel to the VPN server. Both change the IP address websites see; only a VPN protects all apps and hides your activity from the local network and your ISP.

Is a proxy safer than a VPN?

Usually not. Most proxies don't encrypt traffic between you and the proxy, and free public proxies can log or modify what passes through them. A reputable, audited VPN is the safer choice for privacy.

Is a SOCKS5 proxy the same as a VPN?

No. SOCKS5 (RFC 1928) forwards TCP and UDP traffic for apps configured to use it, but it has no encryption of its own. It's lighter and sometimes faster, but your ISP can still see the traffic contents unless the app itself uses encryption such as HTTPS.

Proxy vs VPN: What's the Difference, and Which Do You Need?

Q: Are browser VPN extensions real VPNs?

Most are proxies: they route only that browser's traffic, often over an encrypted HTTPS proxy connection, while other apps use your normal connection. Check the provider's description.

Short answer: both a proxy and a VPN put another server between you and the websites you visit, so both change the IP address sites see. The difference is scope and protection. A proxy usually covers one app or browser and often doesn’t encrypt anything. A VPN encrypts all traffic from your whole device. For privacy and public Wi-Fi, use a VPN. For a quick IP change in one app where privacy doesn’t matter, a proxy can be enough.

At a glance

	Proxy	VPN
Covers	One app or browser that’s configured to use it	The whole device (all apps), optionally with split tunnelling
Encryption	Usually none between you and the proxy (HTTPS proxies are an exception)	Always, from your device to the VPN server
Hides activity from ISP / Wi-Fi operator	No, unless the connection to the proxy is encrypted	Yes: they see only encrypted traffic to the VPN
Changes your IP for websites	Yes, for that app	Yes, for everything
Network layer	Application layer (HTTP) or session layer (SOCKS)	Network layer (IP packets)
Speed	Can be fast (no encryption overhead) or very slow (free public proxies)	Small overhead with modern protocols
Typical cost	Free public lists to paid business proxies	Free tiers, or about €2–5/month for good paid services
Main risk	Operator sees and can alter unencrypted traffic	You trust the VPN provider instead of your ISP

How a proxy works

You tell an app (usually a browser) to send its requests to the proxy server. The proxy makes the request to the website on your behalf and relays the answer back. The website sees the proxy’s IP.

Common types:

HTTP proxy: handles web requests. For HTTPS sites, the proxy passes the encrypted connection through (the CONNECT method), so it sees the site’s domain but not the page contents.
HTTPS (TLS) proxy: the connection between you and the proxy is itself encrypted. Many browser “VPN” extensions and Apple’s Private Relay work like this.
SOCKS5: a general-purpose protocol (RFC 1928) that forwards TCP and UDP for any app that supports it, such as torrent clients or games. No built-in encryption.
Transparent proxy: set up by a network (school, company, hotel) without you configuring anything. It’s used for filtering or caching, not for your privacy.
Residential proxy: routes through IP addresses on consumer home connections, usually sold for web scraping or ad verification. Some networks recruit those home connections through bundled apps, which raises ethical and security questions.

How a VPN works

A VPN app creates an encrypted tunnel at the operating-system level. Every packet from every app is wrapped and encrypted with a protocol such as WireGuard, OpenVPN or IKEv2, sent to the VPN server, decrypted there and forwarded to the internet. Websites see the VPN server’s IP, and your ISP or Wi-Fi operator sees only encrypted traffic going to one server.

Good VPNs add a kill switch (block traffic if the tunnel drops), DNS leak protection (send your lookups through the tunnel) and often an audited no-logs policy.

Where people get confused

“Free VPN” browser extensions

Many are proxies: they protect only that browser. Your email app, games and system updates still use your normal connection and IP. That can be fine for one task, as long as you know it.

Smart DNS

Smart DNS changes only the DNS answers for specific streaming domains so they route via a proxy. It doesn’t encrypt anything or change your IP for other sites.

iCloud Private Relay

Apple’s feature is a two-hop encrypted proxy for Safari and some app traffic: Apple sees your IP but not the site, and the partner relay sees the site but not your IP. It’s good for everyday privacy in Safari, but it isn’t a full VPN and doesn’t let you choose a country.

Tor

Tor is neither a simple proxy nor a VPN: it’s an anonymity network of three relays with layered encryption, usually used through Tor Browser. See Tor vs VPN.

The risk with free proxies

Public proxy lists are full of servers run by unknown people. Anything you send without encryption can be read or changed by the operator, and some proxies inject ads or scripts. Free VPN apps have similar issues. A 2016 academic study of 283 Android VPN apps found that many did not encrypt traffic, many embedded third-party trackers, and some contained malware. Rule of thumb: if you don’t know who runs the server and how they pay for it, don’t send anything private through it.

Which should you use?

Your goal	Best choice
Privacy from your ISP or public Wi-Fi	VPN
Protect every app on your phone or laptop	VPN
Quickly see a site as it appears from another country (nothing private)	Proxy or VPN
Configure a single app, such as a torrent client, through another IP	SOCKS5 from a trusted provider (several VPNs include one) or a VPN
Everyday Safari privacy on iPhone	iCloud Private Relay
Strong anonymity for sensitive browsing	Tor Browser
Web scraping and ad verification at scale (business)	Commercial proxy service, used within its terms and the law

If you pick a VPN, look for an independent no-logs audit, a kill switch and WireGuard-based protocols. Providers such as Proton VPN (free plan), Mullvad, NordVPN, Surfshark and ExpressVPN publish their audits. NordVPN and some others also include SOCKS5 proxy access for single-app use.

Test whatever you choose

After switching on a proxy or VPN:

Check your IP: the address and provider should change.
DNS leak test: with a proxy, DNS often still goes to your ISP.
WebRTC leak test: browsers can reveal your real IP even behind a proxy.
