Different Purposes a VPN Can be Used For

The best thing about a VPN is that it can be used for various purposes because of its various features. Following are some purposes for which a VPN is commonly used for:

Use a VPN for Torrenting

Torrenting is a popular way of sharing files online, but it can also expose your online activities to your ISP and potentially other third parties. By using a VPN for torrenting, you can encrypt your internet traffic and keep your activities private. AstrillVPN offers a high level of encryption, which can help ensure that your online activities remain hidden from prying eyes. 

Additionally, AstrillVPN offers fast download speeds, which is essential for a seamless torrenting experience. It lets you download files quickly and safely without worrying about your ISP or others monitoring your activities.

Use a VPN for Streaming

Streaming services such as Netflix and Hulu are becoming increasingly popular, but they often have geo-restrictions that prevent users from accessing certain content based on their location. By using a VPN for streaming, you can bypass these restrictions and access content from around the world. You can easily change your Amazon Prime country by using a VPN to unblock more content titles. 

AstrillVPN offers servers in various countries, allowing you to connect to a server in a country where the content you want to access is available. Additionally, AstrillVPN offers fast download speeds, which is crucial for streaming content without buffering or interruptions. A VPN will also help you solve Hulu proxy errors to enjoy your favorite movies and TV shows. 

Use a VPN for Gaming

Online gaming is a popular pastime for many people, but it can also expose you to security risks such as DDoS attacks. By using a VPN for gaming, you can protect your IP address and prevent others from targeting you with DDoS attacks. 
AstrillVPN offers fast connection speeds and low latency, which is essential for online gaming. Using AstrillVPN allows you to enjoy a seamless and secure gaming experience without worrying about lag or interruptions. For example, if you’re into gaming and you play CS:GO, then you can use Astrill VPN to fix high ping in CSGO. You can also use Astrill to fix Apex Legends lag issues and enjoy a better gaming experience. 

Use a VPN for Watching Sports

Sports fans can bypass regional limitations using a VPN, and access live streams or broadcasts from anywhere worldwide. Whether it’s a blacked-out NFL game in your area or you’re traveling abroad and want to watch your home team play, a VPN allows you to connect to servers in different locations, granting you access to sports content otherwise unavailable. 

Additionally, VPNs can enhance streaming speeds and offer more stable connections, ensuring you never miss a crucial game moment due to buffering or lag. With a VPN, sports fans can enjoy their favorite soccer or Wimbledon matches, tournaments, and geo-restricted F1 events, regardless of geographical barriers.

Using a VPN for Privacy and Anonymity

By encrypting your internet traffic and directing it through remote servers, a Virtual Private Network (VPN) protects you from prying eyes – such as internet service providers (ISPs), government agencies, and malicious hackers. It creates a secure tunnel, preventing unauthorized parties from intercepting or monitoring your online activity, whether browsing the web, accessing sensitive information, or engaging in online transactions.

Also, VPNs conceal your actual IP address and replace it with one from the VPN server, so your online identity and location are hidden. This protects your personal information from potential threats and enables you to browse the web anonymously, free from invasive tracking and targeted advertising.

Why use a VPN?

VPNs are the easiest and most efficient security tools available for internet users. With AstrillVPN, you can browse the web without a single worry about your privacy as the application changes your IP address and prohibits any trackers from identifying your connection. 

Through this, you can also bypass censorship, including geo-restriction content. You can even do this on an unsecured network as Astrill’s AES 256-bit encryption will keep you protected the whole time. This means you can stay online, securely, even without cellular data. 

On top of this, Astrill is developed wholly in-house and is run by top security experts, cryptographers, senior programmers, and the best networking engineers. They even have a reliable customer support center that can address their user’s concerns within mere minutes. Here are a few more reasons why AstrillVPN could be the right choice for you:

  1. Servers in over fifty locations, including Asia, all with AES encryption protocol that has 256-bit keys, making you unhackable.
  2. Developing everything at home means minimal outages and constant updates, giving you stable connectivity and unbeatable customer support.
  3. A special feature, ‘Smart Mode’, automatically switches on the VPN connection for your convenience only when you visit international websites. This allows for faster browsing.
  4. Another feature that isn’t available elsewhere, is ‘VPN Sharing’ which lets you connect other devices to your PC to share the network. This is all without the use of any extra hardware or routers. Everything just works on the Astrill software!
  5. Lastly, Astrill offers Private IPs that are not shared with any other users and are only available on selected servers. This just adds another layer to your true privacy and full anonymity.

How to Use Advanced VPN Features

AstrillVPN isn’t just a simple VPN like others that you can only use to secure a connection. It has a special pack of Advanced features that you can use to customize your VPN usage experience:


AstrillVPN is one of the few VPN providers that have obfuscated servers, allowing users to bypass strick most VPN blockers. These servers utilize advanced obfuscation techniques to disguise VPN traffic, making it appear as regular internet traffic. This is particularly useful in countries with strict censorship and surveillance measures that attempt to block or restrict VPN usage.

By obfuscating VPN traffic, users can bypass deep packet inspection (DPI) methods employed by governments or ISPs to detect and block VPN connections. Obfuscated VPN servers are especially valuable for users in countries with heavy internet censorship, such as China, Iran, or Russia, where VPN usage is heavily regulated or restricted.

You can use AstrillVPN’s obfuscated servers by using its StealthVPN protocol. This protocol has all obfuscated servers that will bypass any barrier whatsoever. 

The servers in the list having stars on top of them are all obfuscated servers that are ready to use. You can simply select the server of your choice from the list and get connected right away. 


WireGuard is a modern, open-source VPN protocol designed for simplicity, speed, and security. The WireGuard protocol utilizes state-of-the-art cryptographic techniques to establish secure connections between devices. It employs high-speed cryptographic primitives such as Curve25519 for key exchange, ChaCha20 for encryption, and Poly1305 for authentication, offering efficient and lightweight encryption without compromising security.


AstrillVPN is one of the few VPN providers with the Wireguard protocol configured in its app, ready for use. You simply choose the Wireguard protocol from the list of VPN protocols and establish the connection with a single click. 

Kill Switch

AstrillVPN’s kill switch feature is a crucial component of its arsenal for ensuring users’ online privacy and security. A kill switch is a fail-safe mechanism that automatically terminates the internet connection or specific applications if the VPN connection drops unexpectedly. 

This feature prevents unencrypted data from being transmitted over the internet, safeguarding users’ sensitive information from exposure to potential threats such as hackers, surveillance, or ISP monitoring.

AstrillVPN’s kill switch operates at the system and application levels, offering comprehensive protection across various devices and platforms. At the system level, the kill switch can be configured to disable the entire internet connection when the VPN connection is disrupted, ensuring that all network traffic is halted until the VPN connection is restored. This prevents data leaks or exposure of the user’s IP address and online activities to unauthorized parties.

Site Filter

AstrillVPN’s site filter feature, integrated within its application, serves as a powerful tool for users to customize their online experience according to their preferences and needs. This feature empowers users to control access to specific websites or categories of content, providing an added layer of security, privacy, and control over their internet usage.

Application Filter

AstrillVPN’s application filter feature is a valuable tool within its application, designed to offer users control over their internet traffic and application usage. This feature enables users to selectively route specific applications or processes through the VPN tunnel while allowing others to bypass it. It provides flexibility and customization to suit individual needs and preferences.

Application Filter

With the application filter, users can designate which applications should utilize the VPN connection for secure and encrypted communication and which applications should directly access the internet without going through the VPN tunnel. 

Application Filter

This allows users to optimize their VPN usage based on privacy requirements, security concerns, or performance considerations.

Ads blocker

AstrillVPN’s adblocker feature is a convenient tool designed to enhance users’ browsing experience by blocking intrusive advertisements across websites and applications. 

Ads blocker

By effectively filtering out unwanted ads, pop-ups, and other forms of online advertising, AstrillVPN’s adblocker feature helps users enjoy a cleaner, faster, and more streamlined internet experience.

Ads blocker

Users can block ads and also block tracking sites with this feature. The adblocker feature operates at the network level, intercepting and filtering out advertising content before it reaches the user’s device. This not only reduces the visual clutter and distractions caused by ads but also improves page loading times and overall browsing performance, especially on bandwidth-constrained networks or slower connections.

VPN Sharing

AstrillVPN’s VPN sharing option is a unique feature within its application, offering users the ability to securely share their VPN connection with other devices or users. This feature enables users to extend the benefits of their VPN subscription to multiple devices or individuals, enhancing flexibility and convenience in accessing a secure and private internet connection.

VPN Sharing

With the VPN sharing option, users can create a secure Wi-Fi hotspot directly from their device, effectively turning it into a VPN router. Other devices, such as smartphones, tablets, or laptops, can then connect to this Wi-Fi hotspot by setting their IP address as directed by the app and benefit from the encrypted VPN tunnel provided by AstrillVPN

VPN Sharing

The VPN sharing option is particularly beneficial for users who need to secure multiple devices or share their VPN subscription with family members, friends, or colleagues.

Browsers Configuration

Browsers Configuration

This feature allows users to choose specific browsers that they want AstrillVPN to secure their network over, ensuring that only the selected browsers benefit from the encrypted VPN tunnel while others operate normally without VPN protection.

Browsers Configuration

With AstrillVPN’s Browsers feature, users can prioritize privacy and security for their online activities conducted through certain browsers, while maintaining unrestricted access for other applications or services that do not require VPN protection.
