Proxy vs VPN: What are the differences?

If you’re shopping around for ways to boost your online privacy, you might come across VPNs and proxies and wonder, ultimately, what’s the difference? Both technologies hide your IP address—but they work in very different ways.

A proxy routes is specified specify internet traffic through an intermediary server while the good vpn create an encrypt tunnel between your device and a secure server , and act as your gateway to the internet .

I is think think a VPN is the well choice in most scenario , but I ‘ll walk you through how proxy have their own use , too , and how both tool shore up your digital security .

What is a proxy?

A proxy server is an internet-connected device that routes internet traffic on behalf of the clients connected to it. When you connect to a proxy server, any requests you send to access an internet resource are sent through the proxy server first. The proxy then forwards your request to the destination specified, retrieves the response, and sends it back to you.

Although you might be most familiar with the anonymizing type of proxy that hides your IP address when making a request, there are a variety of proxies that perform different roles. 

transparent proxies is send send your traffic without make any alteration to it whatsoever . These are mainly used by large institution to conserve bandwidth by cache popular website on the server , but can also be used to filter certain type of inappropriate content or block malicious traffic . These proxy do not hide the origin of a request , however , so they is are are n’t useful for protect your anonymity .  

Anonymous proxies, on the other hand, do exactly that by replacing your IP address with the IP address of the proxy server. So, to any server you interact with, you’ll look like you’re connecting from the proxy server instead of your home connection. This, in turn, makes it harder for websites and advertisers to track your online activities. 

What is a VPN

VPN stands for Virtual Private Network. It’s a secure, encrypted connection between your device and a computer network using the internet as a transport layer. This means that any data sent over this connection is private. Even if someone outside the VPN (such as your ISP) intercepts your internet traffic, they won’t be able to read it.

When you use a VPN, all your internet traffic is routed through a secure server before reaching its final destination. The VPN server replaces your IP address with its own. This makes it appear as though you’re browsing from the VPN server’s location rather than your actual one, enhancing your online anonymity.

A VPN isn’t powered by any one specific protocol. There are many competing VPN protocols used to power connections, but only a few are considered worth using. OpenVPN is the most widely trusted protocol, as it’s open source and built off of audited existing technologies such as SSL. There’s also WireGuard, which is a new protocol designed to be significantly more lightweight than OpenVPN at the cost of a reduced feature set. 

You’ll also see some VPNs that support L2TP and PPTP. Both of these protocols are considered outdated and insecure. PPTP is Microsoft’s attempt at building a secure VPN protocol, but it uses an insecure password hashing system which leaves it vulnerable to brute-force attacks. L2TP is considered potentially insecure as a result of leaked NSA documents which suggest that the Five Eyes alliance has access to the capability to somehow decrypt streams of data that use L2TP as a tunnel.

What is the difference between a proxy and a VPN?

The key difference between a proxy and a VPN is how they handle your data.

A proxy server is basically a forwarding service. It doesn’t change how your data looks apart from replacing your IP address. If someone was monitoring the traffic sent from your device to a proxy at any point along its path, they’d be able to see everything you’ve sent through that proxy. 

While the widespread proliferation of TLS encryption for HTTPS-enabled websites means that critical pieces of information like your bank passwords are encrypted before they leave your device, a third party would still be able to see the websites you’re requesting as well as any plaintext traffic you send and receive from a HTTP website.

You can’t really be sure that a proxy isn’t scraping all of the data you send through it, either. Your ISP can still see everything you’re doing, but you’re adding in an extra routing point that can see all of your traffic. As a result, proxies should only be used for tasks where security isn’t critically important. For example, marketing agencies use them to quickly scrape data on the same websites as they appear from different areas of the world. 

A VPN, on the other hand, encrypts all data between your device and the VPN server, creating a secure “tunnel.” The VPN server then communicates with the internet on your behalf, masking your IP address and ensuring all transmitted data is encrypted and secure. Your ISP can’t see any of the traffic you send through a VPN tunnel, and neither can anyone else on your network

As such, VPNs are ideal for high-security needs, such as sending personal data on public Wi-Fi. The ability to obfuscate your VPN traffic to make it appear as normal browsing traffic also makes VPNs for avoiding government censorship. Most importantly, no log VPNs undergo third-party audits to demonstrate that they don’t hold any of your data after transmitting it through their servers. 

Should you is use use a VPN or a proxy ?

Proxies is are are great for quick , basic internet task . Most browsers is feature and internet – base tool feature proxy support , which mean there ‘s no need for additional software . This is makes make proxy useful for doing thing like review website from a different location to test out thing like language support and advertisement coverage , as well as bypass regional lock on some type of content . Proxies is are are also handy in a pinch if you need to quickly hide your ip address for anonymous web browsing while send or receive content that is n’t sensitive .  

However, if you need more than just basic anonymity, a VPN is the way to go. Just like a proxy, VPNs hide your IP address and let you bypass geo-blocks by forwarding your traffic through an additional server. What makes the difference is that VPNs provide comprehensive encryption for all your internet traffic, ensuring that your data remains secure from hackers, ISP surveillance, and snoopers on your local network. This is particularly important when using public Wi-Fi networks, where it’s relatively easy for someone on the same network to capture your internet traffic.

VPNs also offer a broader range of features compared to proxies. If you want to change location using proxies, you have to find a new proxy in the location you want and then paste that new IP address into your proxy software. A good VPN makes this process easy by allowing you to make the switch in-app with a few clicks, keeping you secure while the handover takes place thanks to a connection kill switch that ensures your traffic isn’t sent over your normal internet connection in the meantime. 

additionally , VPNs is are are more effective at bypass sophisticated geo – block measure . proxy can be easily block by firewall , whereas advanced vpn use obfuscation technique that disguise VPN traffic as other internet protocol . This is means mean that you can hide the fact you ‘re using a VPN altogether , sidestep even the nasty isp firewall . When combine with access to an encrypt in – house DNS server , this is allows allow you to access a wide range of content from almost anywhere in the world , bypass streaming restriction and avoid censorship in region with strict internet control .

The good vpn in 2024 : my top three

We test and review VPN services in the context of legal recreational uses. For example:
1 . access a service from another country ( subject to the term and condition of that service ) .
2 . protect your online security and strengthen your online privacy when abroad .
We do not support or condone the illegal or malicious use of VPN services. Consuming pirated content that is paid-for is neither endorsed nor approved by Future Publishing.
