The proxy vs VPN question usually arrives as "which one hides my IP better?", but that framing misses the real difference. Both send your traffic out through another address. A proxy does it per application or per request, and it is built for controlling which IP a specific tool uses. A VPN does it for the whole device, wrapping all traffic in an encrypted tunnel. Once you see that split, picking the right one for a given job is usually obvious.
The one-paragraph version
A proxy is a middleman that an application chooses to talk through. Your browser, scraper or script is configured with the proxy's host and port, and only that application's traffic goes through it. A VPN creates a virtual network interface on your device and routes everything (every app, DNS, background services) through an encrypted tunnel to the VPN server. Proxies give fine-grained control and many separate IPs; VPNs give whole-device coverage and encryption of the path to the server.
Proxy vs VPN side by side
| Proxy | VPN | |
|---|---|---|
| Scope | One app, one browser profile, or one request | The whole device or network |
| Setup | Host, port and credentials in each app | A client app or OS profile, then on or off |
| Encryption to the server | Not added by the proxy itself | Yes, the tunnel is encrypted |
| Protocols | HTTP or SOCKS5 (TCP connections) | All IP traffic, including UDP |
| Many IPs at once | Easy: different apps or threads use different proxies | Usually one exit IP per connection |
| DNS | Depends on settings (for example socks5h sends lookups through the proxy) | Normally handled inside the tunnel |
| Typical uses | Scraping, account separation, geo testing, IP allowlists | Public Wi-Fi safety, reaching a private network, whole-device location change |
Encryption: the part people get wrong
A proxy does not encrypt your traffic by itself. That sounds alarming until you remember that almost all web traffic is already HTTPS. When a browser uses an HTTP proxy for an HTTPS site, it sends a CONNECT request and the TLS session runs end to end between the browser and the website. The proxy sees the destination host name and port, but not the pages, cookies or form data. The same is true over SOCKS5. The details are in SOCKS5 vs HTTP proxy.
What a proxy does not protect:
- Plain HTTP traffic, which the proxy and anyone on the path can read.
- Your proxy credentials, which are sent in a simple encoded form to an HTTP proxy. On an untrusted network that is a real consideration.
- Traffic from apps that ignore the proxy setting.
A VPN encrypts everything between your device and the VPN server, regardless of the app. After the VPN server, traffic continues to the internet as normal, so HTTPS is still what protects your data from the server onward.
Application level vs system level in practice
The scope difference has practical consequences.
With a proxy you can run ten browser profiles on one computer, each with its own IP, or a scraper with fifty workers each assigned a different proxy. You can also route only the traffic that needs a specific location and leave everything else, such as updates, video calls and chat, on your normal connection. That is why proxies are standard for multi-account work, rank tracking and price monitoring.
With a VPN, everything moves together. That is exactly right when you want the whole laptop to behave as if it were on another network, when you join untrusted Wi-Fi, or when you need to reach servers on a private network. It is awkward when you need several identities at once, because one tunnel usually means one exit IP for everything.
On phones the difference is sharper still. The Wi-Fi proxy setting on iPhone and Android only covers HTTP traffic from apps that respect it, as explained in setting a proxy on Android and iPhone. A VPN app covers every app.
Which one fits your task
Use this short decision guide:
- You need different IPs for different accounts, profiles or threads. Use proxies, one per identity. A dedicated proxy is the usual choice because the IP is not shared with other customers. Follow each platform's rules on multiple accounts.
- A service only accepts connections from a fixed IP you control (an allowlist on a database, an admin panel or an API). Either works. A static proxy is simplest for one tool; a VPN on your own server suits a team. See static IP allowlisting with a proxy.
- You want to protect yourself on public Wi-Fi. Use a VPN. A proxy will not encrypt non-HTTPS traffic or apps that ignore it.
- You need everything on the device, including games or calls, to appear from another country. Use a VPN. Proxies only handle TCP and only for configured apps.
- You scrape or test from servers. Use proxies. They plug straight into curl, Python, Playwright and similar tools.
Sometimes you need both: for example a VPN for the office network and proxies inside your scraping code.
Where the IP comes from matters too
Whether you use a proxy or a VPN, the exit IP has a type. Many VPN and proxy exits use datacenter or hosting IP ranges, which websites can often identify as such. ISP proxies use addresses registered to internet service providers, and static residential proxies use addresses from home-broadband ISPs, which look like a regular home user. Neither type guarantees access to any particular site; the datacenter vs static ISP comparison covers the trade-offs.
What Cloudj offers on each side
On the proxy side, Cloudj sells dedicated static IPv4 proxies, with IPs registered to an ISP and assigned to one customer only, in Vietnam, the United States, Japan, South Korea, Singapore, Hong Kong and the United Kingdom, plus static residential ISP proxies in the United States and Vietnam. They support HTTP or SOCKS5 where the location allows, with username and password or an IP whitelist of up to 20 addresses. The proxy overview has the details.
Cloudj does not ship VPN apps. The VPN service page offers the same dedicated proxies, marketed as a "VPN with a dedicated IP": you get a fixed IP for your browser or tools over HTTP or SOCKS5, not an encrypted device-wide tunnel. If you need a real VPN tunnel, a small cloud server with WireGuard works well; the WireGuard VPN on a VPS guide walks through it.
FAQ
Is a VPN safer than a proxy?
For protecting traffic on an untrusted network, yes, because a VPN encrypts everything to the server. For HTTPS sites both keep page content private, since TLS already encrypts it end to end.
Can I use a proxy and a VPN at the same time?
Yes. Traffic from the proxied app goes through the VPN tunnel first and then to the proxy, so the proxy sees the VPN's IP as the client. Remember this if your proxy uses an IP whitelist.
Does a proxy hide my IP from websites?
Websites see the proxy's IP for traffic sent through it. Apps that bypass the proxy, and browser features such as WebRTC, can still reveal your real IP unless they are configured correctly.
Which is better for scraping?
Proxies, because each worker or request can use a different IP and they plug directly into scraping libraries.
Choosing your next step
If your work needs separate IPs per tool or account, start with a few proxies and test them with curl before scaling. You can order them in the Cloudj console, where they are ready in a few minutes, and check live prices on the pricing page.
