Is AstrillVPN the most secure VPN? Evaluate Our Powerful Encryption

If you’re concerned about privacy online and want to get a VPN to secure your internet connection, it’s a smart thinking. But with so many VPN services out there, how do you choose? You’ve probably heard of AstrillVPN, one of the most popular options. But is it the most secure and private? Before you sign up for any VPN, you need to understand what actually matters when it comes to protecting your data. Not all VPNs are created equal, and some could put your privacy at risk. We took a close look at AstrillVPN and other top services to see how they measure up in terms of security, privacy, speed, reliability, and price. Here’s everything you need to know about how secure is AstrillVPN.

What Makes a VPN Secure? Understanding VPN Encryption

A VPN is only as secure as its encryption. For the best protection, AstrillVPN uses military-grade 256-bit AES encryption. This is the same level of encryption used by governments and banks to keep data secure.

With 256-bit AES encryption, your internet connection and data are encrypted and decrypted over 2^256 possible keys. This makes it nearly impossible for hackers to crack. Some other VPNs only use 128-bit encryption, which is much less secure.

AstrillVPN also has a strict no-logging policy. It does not log or store any of your private browsing data, online activities or personal information. Your anonymity and privacy are protected.

AstrillVPN allows you to choose from multiple security protocols like OpenVPN, L2TP/IPSec, PPTP and StealthVPN to suit your needs. For most people, OpenVPN offers the best balance of speed and security. It is an open-source protocol that is very difficult to block or crack.

Using features like VPN kill switch, DNS leak protection, and IPv6 leak protection provide an added layer of security. If your VPN connection drops, the kill switch will cut off your internet access to avoid sending data over an unencrypted connection. The leak protection features prevent your real IP and DNS information from being exposed.

With robust security, anonymity, and privacy features built right in, AstrillVPN ranks highly for safety and protection. You can browse, stream, and download content with confidence, knowing your data and identity are secure.

AstrillVPN’s Security Features and Protocols

AstrillVPN’s Security Features and Protocols

AstrillVPN uses military-grade 256-bit AES encryption for maximum security. This is the same level of AstrillVPN encryption used by governments and banks to keep data secure.

AstrillVPN offers several protocol options to suit your needs:


This open-source protocol is considered very secure and is a great all-round choice. It works on most devices and operating systems.


A secure protocol that provides encryption and authentication. It’s compatible with most devices but can be slower than OpenVPN.

AstrillVPN also has extra features like a kill switch to cut your internet connection if the VPN drops, DNS leak protection, and split tunneling which allows you to choose which apps use the VPN.

With strong encryption, a choice of VPN protocols, and useful privacy features, AstrillVPN aims to keep your online activities under wraps. If watertight security and anonymity are priorities for you, AstrillVPN seems a solid option to consider for keeping you safe on the web.

How Astrill Stacks Up Against Other Top VPNs?

When comparing VPN services, security and privacy are top concerns. How does Astrill stack up against other leading VPNs?

Astrill uses strong 256-bit AES encryption, which is the industry standard. It also offers perfect forward secrecy, an added layer of protection that generates unique encryption keys for each session. This prevents hackers from accessing your data even if they obtain your private key.

Other popular VPNs also use 256-bit AES encryption and perfect forward secrecy. For encryption and security protocols, Astrill is on par with the top VPNs. When it comes to server locations, Astrill offers over 300+ servers in 57+ countries. So, Astrill has a good number of locations but not quite as many as the top two VPN providers. Overall, Astrill provides strong security and privacy comparable to the leading VPN services. It uses high-level encryption, has a proven no-logs policy, and offers servers in many locations.

How to secure VPN connection? Tips for Maximum Security

How to secure VPN connection? Tips for Maximum Security

For maximum security, there are a few tips you should keep in mind when using AstrillVPN.

Use strong encryption

Choose an encryption protocol like OpenVPN or IKEv2/IPSec over weaker ones like PPTP. Stronger encryption makes your data much harder to decrypt if intercepted.

Enable the Kill switch/App Guard

The kill switch/App Guard cuts off your internet access if the VPN connection drops to avoid exposing your real IP address. Enable this feature in the AstrillVPN app to ensure you stay protected even if the VPN temporarily disconnects.

Use a virtual private server

Connecting to a virtual private server (VPS) in a location you trust adds an extra layer of security and can bypass VPN blocks. AstrillVPN offers VPS services in multiple countries.

Use a Stealth VPN

AstrillVPN uses stealth technology to disguise your VPN traffic and bypass VPN blocking. Enable stealth mode if you experience issues connecting to certain networks. Astrill’s stealth VPN aims to hide your VPN traffic by disguising it as normal internet traffic. This stealth mode uses special protocols like OpenWeb and OpenVPN with obfuscation to mask your VPN connection. The goal is to prevent your VPN use from being detected by your internet service provider, network administrator, or government censorship.

Use a dedicated IP address

For some users, a dedicated IP address assigned only to you can provide more security. AstrillVPN offers dedicated IPs for an additional monthly fee. It comes with the best pricing of $5.

Keep the app up to date

Update the AstrillVPN app on your devices regularly to ensure you have the latest security patches and updates. Outdated software is more vulnerable to exploits.

Staying secure online means taking proactive steps to protect your privacy. Following these best practices will help ensure your VPN connection and internet traffic remain private when using AstrillVPN.

Is AstrillVPN the Most Secure VPN?

AstrillVPN does have strong security features that can help protect your privacy. It offers military-grade 256-bit AES encryption, a kill switch to block internet access if the VPN drops, and a no-logging policy.

Some of its best options to consider:

  • AstrillVPN only allows 5 simultaneous connections.
  • Their customer support has received the best reviews on good response times and helpful answers.
  • AstrillVPN can be on the pricier side if you pay month-to-month. Longer plans offer the best value.
  • AstrillVPN have additional security tools like DNS leak test, Password leak test, VPN leak test, IPV6 leak test, and many others to maintain your security.

If absolute anonymity and affordability are most important, you may want to consider other options. But for strong security, ease of use and access to streaming sites, AstrillVPN is a solid choice, as long as you go in with realistic expectations about their policies and customer service.

Overall, while AstrillVPN has strong security and privacy features, there are a few compromises to keep in mind. As with any VPN, do your own research to determine if AstrillVPN meets your specific needs before subscribing. But if you’re looking for a VPN focused on security and performance, AstrillVPN deserves consideration as a contender for the most secure VPN connection.

Secure AstrillVPN protocols

Secure AstrillVPN protocols

AstrillVPN offers several different connection modes to suit your needs. Depending on what you’re using the VPN for, some modes may be better than others.

StealthVPN protocol

StealthVPN hides the fact that you’re using a VPN, disguising your traffic to bypass VPN blocks. This is useful if you live in a country with heavy internet censorship or are connecting to a network with VPN restrictions. StealthVPN uses modified VPN protocols to mask your VPN connection.

OpenWeb protocol

OpenWeb allows you to access censored websites and social media platforms in restrictive countries. It works similarly to StealthVPN mode but focuses specifically on accessing blocked websites. If you can’t access websites like Facebook, Twitter or Wikipedia where you are, OpenWeb mode should do the trick.

Wireguard protocol

Wireguard is a new open-source VPN protocol that is reputed to be faster and more secure than the older protocols used by most VPN services like OpenVPN or IPsec. AstrillVPN offers native Wireguard protocol support on all platforms which provides some key benefits:

  • Wireguard is designed to be extremely lightweight and fast. It uses modern kernel technologies like UDP hole punching to achieve high speeds. Most users report faster speeds and lower latency compared to OpenVPN.
  • Wireguard uses state-of-the-art cryptography like Curve25519, ChaCha20, and Poly1305 to encrypt your data and authenticate your connection. It is also designed to be simpler than other VPN protocols, with less potential for vulnerabilities.
  • Wireguard is open-source software so its code can be scrutinized by experts to verify its security. This transparency gives many users more confidence in the protocol.

While AstrillVPN has strong security and privacy features overall, these different modes allow you to customize the level of anonymity and access you need. Whether circumventing censorship, accessing geo-restricted content or maintaining the highest level of privacy, AstrillVPN has a mode for your needs.

Proxy settings

To ensure your AstrillVPN connection is as secure as possible, you’ll want to configure the proxy settings. The proxy server acts as an intermediary between your device and the internet, hiding your true IP address and location.

Choose your proxy protocol

Astrill offers a few options for proxy protocols:

  • OpenWeb – An unencrypted but fast protocol good for streaming
  • OpenVPN (UDP or TCP) – A popular encrypted protocol, good balance of speed and security
  • StealthVPN – Obfuscated protocol to bypass VPN blocks, slower speed
  • WireGuard – Newest encrypted protocol, fast with strong security

For the best security, choose OpenVPN (UDP or TCP) or WireGuard. These provide encryption to hide your activity from prying eyes.

Select a proxy server location

Choose a proxy server location in a country where internet is largely uncensored and privacy laws are strict. Locations like Switzerland, New Zealand, and Norway are good options. The further the server is from your location, the more “hops” your data has to make, increasing security. However, more distance often means slower speeds.

Use Obfuscated server( StealthVPN)

Use Stealth Mode to mask your OpenVPN internet traffic and make it appear more like regular internet activity. This adds an extra layer of obfuscation to help bypass VPN blocks and hide the fact you’re using a VPN.

Use a dedicated IP (optional)

For an additional monthly fee, you can obtain a dedicated proxy IP address only used by you. This makes it more difficult to match web activity to your account and may provide improved access to geo-restricted streaming services.

Following these best practices for configuring your AstrillVPN proxy settings will help ensure you have an optimized, encrypted connection and anonymous web browsing experience.


Here are some frequently asked questions about AstrillVPN’s security:
