Security and privacy on the internet remain important for users, especially when working with public networks, online services, and data transmission. To protect connections and hide network activity, VPNs and proxy servers are most commonly used.
Despite the similarities of these tools, they operate differently and have different purposes. A VPN encrypts internet traffic and provides a secure connection, while a proxy server forwards user requests through an intermediary server, helping to change the IP address or restrict access to certain resources.
In this article, specialists from VPS-UP will discuss the main differences between VPNs and proxy servers, their advantages, disadvantages, and use cases.
Main Types of Proxies and Their Purpose
A proxy server acts as an intermediary between the user's device and a website or online service. In this case, requests first go to the proxy server and are then forwarded to the desired resource. As a result, the website sees the proxy's IP address instead of the user's real IP address.
Proxy servers can be used to change IP addresses, bypass access restrictions, filter traffic, or monitor network activity. The most commonly used types of proxies are:
- HTTP proxies — work only with web traffic and are usually used in browsers. In this case, HTTP and HTTPS requests pass through an intermediary server before connecting to the site.
- SOCKS proxies — operate at a lower network level and can transmit various types of traffic, not just web requests. They are often used for applications, online games, messengers, or torrent clients.
- Transparent proxies — can operate without explicitly notifying the user about traffic redirection. They are often used by companies, educational institutions, hotels, or public Wi-Fi networks to filter content, authorize users, or monitor network activity.
Separately, there are private proxy servers that provide the user with a dedicated IP address. They offer more control and reduce the risk of blocks due to the actions of other users. At the same time, proxy servers usually do not provide the same level of encryption and traffic protection as VPNs.
How to Set Up a Proxy Server in Windows
In Windows, a proxy server can be set up in several ways depending on the parameters provided by the provider or system administrator.
The most commonly used setup options are:
- automatic detection of proxy settings;
- connection via an automatic configuration script (PAC script);
- manual entry of the proxy server's IP address and port.
If the proxy server is provided by a company, provider, or network administrator, the necessary parameters are usually provided separately.
For automatic proxy setup in Windows:
- open the "Network and Internet" section in system settings;
- go to the "Proxy" tab;
- enable the "Use setup script" option;
- enter the PAC script address provided by the proxy provider;
- save the changes.
For manual proxy setup in Windows:
- open Windows settings and go to the "Network and Internet" section;
- open the "Proxy" tab;
- in the manual setup block, enable the "Use a proxy server" option;
- enter the IP address and port of the proxy server in the respective fields;
- save the changes.

How VPN Works and What It Is Used For
A VPN (Virtual Private Network) redirects the user's internet traffic through a remote server, hiding the real IP address and location of the device. Unlike a proxy server, a VPN operates at the operating system level and protects all network traffic, including background applications and system processes.
One of the main features of a VPN is the encryption of traffic between the user's device and the VPN server. This helps protect data from interception and reduces the possibility of tracking activity by internet providers, public Wi-Fi networks, or third parties.
VPNs are often used to protect data on public networks, for remote work, to bypass geographical restrictions, and to enhance privacy on the internet. For corporate networks or personal VPN services, VPN servers are often deployed on VPS/VDS or Dedicated Servers, allowing for complete control over settings and network security.
At the same time, the level of security of a VPN largely depends on the provider itself. Some VPN services may keep logs of user activity or share data with third parties, so it is advisable to carefully review the service's privacy policy before use.
VPN and Proxy Server: What Is the Difference
Both tools help hide the IP address and change the route of internet traffic. However, there are important differences between VPNs and proxies in terms of the level of protection, operating principles, and use cases.
VPN:
- encrypts all internet traffic between the device and the VPN server;
- operates at the operating system level and protects not only the browser but also other applications;
- helps protect data from interception on public networks;
- may reduce connection speed due to traffic encryption;
- is usually used through paid VPN services or corporate solutions.
Proxy Server:
- does not provide full traffic encryption;
- usually works only for a specific application or browser;
- is primarily used to change IP addresses, bypass restrictions, or filter traffic;
- often works faster than VPN due to the lack of encryption;
- can be either free or paid depending on the type of service.
VPNs are generally better suited for protecting sensitive data and secure online work, while proxy servers are more often used for technical tasks, changing IP addresses, or working with specific services.
Free VPNs and Proxies: What Risks to Consider
Free VPN and proxy services can pose risks to users' privacy and security. Since such services require costs to maintain infrastructure, some providers may compensate for this by displaying ads, limiting speed, or collecting data on user activity.
In some cases, free services may keep connection logs, analyze traffic, or share some data with third parties. Therefore, it is advisable to carefully review the service's privacy policy before using a VPN or proxy server.
Paid VPN services usually offer a higher level of protection, more stable connection speeds, a larger number of servers, and modern encryption protocols. They also often provide technical support and regular infrastructure updates.
VPNs and proxy servers can be used simultaneously; however, this setup requires more complex configuration and is not always justified. In most cases, it is sufficient to choose one tool based on the user's needs and the level of protection required.
VPN or Proxy Server: What to Choose
VPNs and proxy servers solve similar tasks but have different levels of protection and different use cases. If security and privacy are the main priorities, a VPN is usually the better choice as it encrypts traffic and protects all network connections at the operating system level.
Proxy servers are more suitable for specific technical tasks — for example, changing IP addresses, working with specific services, or bypassing certain restrictions. At the same time, they usually do not provide the same level of traffic protection as VPNs.
The final choice depends on the user's needs: for secure online work and data protection, VPNs are more commonly used, while proxy servers can be convenient for specific scenarios involving traffic or network connections.
