VPN vs proxy: what the proxy leaves uncovered

A VPN and a proxy both change what the internet sees when you connect, but they draw the coverage line in different places. A VPN encrypts every app and background process on the device; a proxy is set up for one browser, script, or app, and everything else on that device keeps connecting the normal way. A VPN’s tunnel is encrypted by design — most proxies are not. For the mechanics of how that tunnel works end to end, see our guide to what a VPN is and how it works.

Every provider in our full VPN rankings sells the VPN side of this comparison, and a few of them also sell a lighter, browser-only proxy alongside it. Proton VPN’s own support pages document exactly what that proxy does not cover, which turns “VPN or proxy” from a guess into something you can check against a vendor’s own words. Prices and product details below are as the vendors published them on 26 Jul 2026.

VPN vs proxy, by what each one actually does

	VPN	Proxy
What it covers	Every app and background process on the device	Only the app, browser, or script pointed at it
Encrypts your traffic	Yes, the whole tunnel	No, not by default
Network layer (OSI model)	Layer 3 to 4 — network and transport	Layer 5 to 7 — session and application
DNS lookups	Routed through the encrypted tunnel	Usually resolved outside the proxy, visible to your ISP
Where you set it up	Once, in one app, applied system-wide	Per app: browser settings, an extension, or proxy fields in code
Traffic outside the proxy	None — everything routes through the tunnel	Continues over your normal, unencrypted connection
When the connection drops	Can leak onto the open network without a kill switch	The app just reconnects without it — there was no tunnel to lose
Typical cost	Flat monthly rate, about $5 to $15, unlimited bandwidth	Priced by data or IP: roughly $0.50 to $25 per GB depending on type
What it does best	Whole-device privacy on any network	Per-app IP changes and high-volume automation

Which one actually encrypts your traffic?

The VPN, every time you connect. A VPN wraps the whole tunnel in encryption — Windscribe’s own comparison of the two describes its VPN’s encryption as AES-256, “making it unreadable to hackers or your ISP.” AWS draws the same line in its comparison: encryption is what gives a VPN “broader applications than a proxy server,” because a proxy typically swaps the visible IP address and leaves the payload readable. Windscribe’s comparison makes the same admission from a VPN vendor’s side: most proxies do not encrypt at all. The minority that claim to are usually acting as a man-in-the-middle. That means the proxy operator itself can read your traffic, not just someone intercepting the connection.

What happens to everything the proxy does not touch?

It travels normally, in the clear. Set a proxy for your browser, and every other program on the device keeps connecting the normal way. An email client, another browser, background sync, any app making its own network calls — none of it is encrypted, and all of it shows your real IP address. Windscribe’s own comparison names the specific gap that catches people out most: proxies “usually fail to handle your DNS queries,” so even the domain names you visit go straight to your ISP, in the clear, while a VPN routes that same lookup through its tunnel. A dropped VPN connection has a known failure mode too — the tunnel goes down and, without a kill switch holding traffic until it reconnects (see our guide to VPN kill switches), your device can fall back to the open network. A proxy has no equivalent concept: the app it was configured for just reconnects without it, because there was never a tunnel to lose.

Which is faster, and which is more reliable?

Proxies have a real speed argument: skipping encryption removes a processing step, so a proxy can be faster than a VPN on the same connection, per NordLayer’s comparison for business users. NordLayer’s own caveat matters just as much — a well-run VPN server can still outrun a cheap or overloaded proxy, so “faster” depends on whose infrastructure you are using, not the category alone. On reliability the same comparison is direct: VPN connections are the more dependable of the two, and proxy connections — free ones especially — drop more often. Treat the speed and reliability claims as directional, not measured — they come from NordLayer’s comparison, and none of the providers here publish independent speed data precise enough to check them against.

What does each one cost?

A VPN is usually a flat monthly subscription with unlimited bandwidth. Proxies.sx puts the typical VPN range at $5 to $15 a month, covering five to ten devices under one price. A proxy is priced by consumption instead. Proxies.sx lists datacenter proxies at $0.50 to $2 per gigabyte (or $5 to $20 a month unlimited), residential proxies at $2 to $15 per gigabyte, and mobile proxies at $4 to $25 per gigabyte plus $10 to $30 a month per port. Volume discounts run roughly 30 to 50 percent at scale. That structure makes sense once you know what each buyer is paying for: a VPN subscriber buys unlimited use of one connection, while a proxy buyer is usually buying IP addresses and bandwidth by the unit — often for automation that would burn through a VPN’s device limit in minutes.

The proxy trap: when your VPN app is also a proxy

Several VPN companies also sell a lighter, browser-only option and badge it as part of the same product. Proton VPN’s browser extension is exactly this: a proxy that routes browser traffic through Proton’s VPN servers, not the full VPN app. Proton’s own support page spells out what that gets you and what it does not. It prevents websites from seeing your real IP address and stops your ISP from seeing what you browse. It does not protect traffic outside the browser, cannot protect data sent before the extension finishes loading, and cannot stop other browser extensions from changing its settings — though it will warn you when one does. Proton names one specific leak directly: embedded email clients using SMTP or IMAP route straight to their mail server, bypassing the extension entirely, and experimental browser features can open connections that ignore the extension’s proxy settings too. Because the extension opens a new HTTPS connection for each session rather than holding one persistent tunnel, Proton says that makes it “slightly more vulnerable to fingerprinting attacks than using the full VPN app.” Its own conclusion: fine for most people, but “you should use our full VPN app if security is a high priority for you.”

Someone who installs a “VPN extension” from a VPN company reasonably assumes their whole machine is covered. It is not — and Proton spells this out itself, in writing, rather than leaving it undocumented. If you are running the extension today, moving to the full Proton VPN app is the exact fix Proton recommends, and our Proton VPN review covers what that app adds.

What a proxy is actually good at

None of this makes a proxy useless — it makes it a different tool. Proxies also split by protocol and origin, and the split is worth knowing: an HTTP proxy only understands web traffic, a SOCKS5 proxy is protocol-agnostic and can carry other kinds of connections, and residential, datacenter, and mobile describe where the IP address comes from — a real ISP customer, a data center, or a phone carrier — not the protocol. Whichever kind, per-app routing is the point, not a limitation. A scraper or automation script can run through a proxy without installing anything system-wide, and different processes can each use a different IP address at the same time. Windscribe’s own comparison names web scraping at scale as a case where proxies genuinely win, because “VPN IPs get blocked at scale” while a pool of datacenter or residential proxy IPs can rotate. Proxies.sx makes the same point from the buyer’s side: a VPN subscriber shares one IP address across every device on the account, while a proxy setup can run dozens of scrapers or bot accounts in parallel, each on its own address — a job a VPN’s five-to-ten-device limit was never built for. None of this comes with a detection rate or a block-rate number attached; treat it as a difference in what each tool is built to do, not a measured outcome. A proxy is built to make one connection cheap to replace. A VPN is built to protect one whole device.

Choose a VPN if

• You want every app and background process protected, not just the browser.
• You are on a public or untrusted network and need the traffic itself encrypted, not just the visible IP address changed — see our guide to public Wi-Fi safety for what is actually at risk there.
• You would rather pay one flat subscription than by the gigabyte or by the IP address.
• Reliability matters more than shaving off milliseconds — VPN connections drop less often.

Choose a proxy if

• You need several different IP addresses running at once — scraping, automation, or managing multiple accounts.
• You only need to reroute one app or script, not the whole device.
• You are comfortable configuring it per use rather than once for the whole system.
• Your usage is occasional or low-bandwidth, where per-GB pricing can cost less than a flat subscription.

Frequently asked questions

What is the difference between a VPN and a proxy?

A VPN encrypts your traffic and covers everything the device sends, apps and background processes included. A proxy is set up for one browser, script, or app; it can swap that one thing's visible IP address, but it does not encrypt by default, and nothing else on the device is affected.

Is a VPN better than a proxy?

For general privacy and everyday browsing, yes — encryption and whole-device coverage are what a proxy does not offer. A proxy wins for narrower jobs, like running many IP addresses at once for scraping or automation, where a VPN's per-account device limit gets in the way.

Does a proxy hide your IP address?

Yes, for whatever you configured it to cover. The app or browser pointed at the proxy shows the proxy's IP address instead of yours. Anything else on the same device — another browser, background apps, the operating system — still shows your real one.

Is a proxy encrypted like a VPN?

Usually not. A VPN encrypts the entire tunnel by design. Most proxies pass traffic through without encrypting it, and the minority that advertise encryption are typically acting as a man-in-the-middle, meaning the proxy operator can read what passes through rather than just someone intercepting it externally.

Which is faster, a VPN or a proxy?

Often a proxy, since it skips the encryption step a VPN performs. That is not a fixed rule — a well-run VPN server can outrun a cheap or overloaded proxy — and VPN connections are generally the more reliable of the two; proxy connections, free ones especially, drop more often.

Do VPNs work for all apps, while proxies only work for browsers?

VPNs cover every app and background process because the encryption happens at the device level, before traffic leaves for the network. A proxy is typically configured per app — most often a browser, though scraping tools and scripts can point at one too — so anything not configured to use it connects normally.

Which is better for public Wi-Fi, a VPN or a proxy?

A VPN. Public Wi-Fi puts your traffic in front of everyone else on the network, and encryption is what makes that traffic unreadable to them. A proxy without encryption leaves the same data exposed on the network, even though it shows a different IP address to the sites you visit.

When should you use a proxy instead of a VPN?

For narrow, per-app jobs rather than everyday privacy — web scraping or automation that needs many IP addresses running at once, managing several accounts, or a quick IP change for one browser session. For anything system-wide, or any network you do not control, a VPN covers more.
