The Best VPNs in 2025 for Online Privacy & Security

In the world of online security and privacy protection, you may have heard of the terms "VPN" and "Proxy". But what exactly are they and what is the difference between them? Although these technologies may seem complicated at first glance, they have very simple functions. In this article, we will explain in an easy and accessible way what they are, how they work, and the differences between VPN and Proxy.

What is VPN? What is Proxy? What is the difference between VPN and Proxy?

1.VPN

TheVPN(Virtual Private Network) creates an encrypted "tunnel" between your device and the internet, protecting your online activities from interception or monitoring. In addition to hiding your IP address, it encrypts all the data you send and receive.

Imagine you're in a café using public Wi-Fi. While public Wi-Fi is convenient, it's very insecure, because anyone on the same network can access the data you're transmitting. You may be browsing the web, accessing your accounts, or even making purchases, and without protection, all of this information can be seen by others.

In this case, if you use a VPN, it would act as a "safety box." All your "cards" (your online activities) would be placed in a secure "chest" (VPN) and sent. Even if someone sees the "chest" on the way, they won't know what's inside. VPN not only protects your security on public Wi-Fi, but it also hides your IP address, preventing others from monitoring your online activities.

VPN Features:

• It hides your real IP address.
• Encrypts all information sent, preventing others from hearing it.
• It offers privacy protection, especially when you are using public Wi-Fi networks.

2.Proxy

OrProxyIt is an intermediary server that receives your access requests and sends them to the desired website. It can also hide your IP address, but it doesn't offer encryption.

For example, let's say you want to watch a video that's only available in another country, but you're in Brazil. You can find a "friend" abroad (Proxy) and ask him to access the video for you, and then send you the content. This way, the website will see your friend's IP address and not yours. This process doesn't encrypt communication, and information isn't protected, but you can bypass restrictions and access what you want.

Proxy Functions:

• It hides your real IP address.
• Allows you to access blocked content.
• It doesn't encrypt data, so security is lower.

Difference Between VPN and Proxy

1.Cryptography:

• VPN: Encrypts all traffic, as if you were putting all your data inside a sealed box and sending it. No one can see what's inside.
• Proxy: It doesn't encrypt traffic, it just replaces your IP address, as if you were asking a friend to buy something for you, but the letters (data) they send can be seen by anyone.

2.Safety:

• VPN: More secure, as it encrypts data and protects your privacy.
• Proxy: It doesn't encrypt the data, so it has inferior security and people can see what you're doing.

3.Usage Scenarios:

• VPN: If you're using public Wi-Fi or need to ensure the security and privacy of your online activities, use a VPN.
• Proxy: If you just need to bypass some website restrictions or change your IP address, Proxy may suffice.
