best-encrypted-VPN-2020

With America’s National Security Agency, UK’s Government Communications Headquarters, and China’s Great Firewall carrying out unjust surveillance on the internet, online privacy and security are impossible to achieve without a good encrypted VPN.

However, not every VPN in the industry provides the kind of top-notch encryption that can help safeguard your privacy. In fact, since encryption depends on the security protocols and not on the VPN service provider, you should consider choosing VPNs based on the protocols being offered rather than relying on the VPN provider’s name.

So to help you choose the top encrypted VPN for your needs, I’ve rounded up some of the most secure VPN services you can use in 2021.

6 Best Encrypted & Most Secure VPNs

VPN Encryption Algorithms

Before discussing VPN encryption algorithms in detail, you should know what encryption in the VPN industry is all about. You can consider encryption as a lock that secures your online data. Without opening the lock, snoopers and ISPs cannot track your online activities.

The innovative computer ciphers are nearly impossible to crack. It means the latest encryption algorithms are unbreakable even if you use supercomputers to blow the computer ciphers. The more difficult the encryption algorithm, the tougher the cipher is to crack.

Therefore, the AES 256-bit encryption is assumed to be the most secure encryption level compared to AES 128-bit encryption.

How to choose the VPN with the best Encryption?

When searching for the best VPN for encrypted data transfer and Internet surfing, there are a few considerations that you should bear in mind. These are highlighted below:

  • Encryption Protocol/Algorithm: This is the most important factor that you should consider. Your VPN provider should support the strongest encryption. For instance, OpenVPN and IKEv2 offer the most robust standard of encryption. On the other hand, you should avoid VPN providers that only offer outdated encryption like PPTP, which is fraught with security vulnerabilities.
  • Server Locations: If you access the Internet using different server locations, you can make it that much more difficult for your ISP to detect your real identity. Therefore, many server locations mean you can choose any virtual location from anywhere in the world. 
  • Privacy Policy: Finally, no encryption amount can protect you if your VPN provider has a poor privacy policy. You need to ensure that the privacy policy is transparent and the provider does not log your data. As such, we strongly recommend using a VPN provider that avoids any logging of data whatsoever to protect your privacy.

VPN Encryption Standards

When it comes to evaluating different kinds of VPN encryption standards, nothing beats AES’s significance (Advanced Encryption Standard). Here is the list of some of the best encryption:

  • AES
  • Blowfish
  • Camellia
  • Handshake
  • RSA
  • Diffie-Hellman and ECDH

AES

AES is the most efficient online encryption standard that offers security to the users’ information to another level. Moreover, it uses 128 and 256- bit level of protection that improves your data’s safety straight away and ensures maximum security.

Blowfish

OpenVPN uses the Blowfish-128 encryption standard that you can assume as the second line of defense and security.

Camellia

Camellia is an innovative cipher the users can consider in place of AES cipher. However, it does not offer the level of security AES provides to the users.

Handshake Encryption

OpenVPN, a VPN protocol, uses handshake encryption that enables the OpenVPN client and VPN server to create secret keys. These secret keys allow secure communication between the OpenVPN client and the VPN server.

RSA

RSA is a public key you can use to protect your data instantly. Still, if you have the luxury to use 256-bit AES military-grade encryption, you should not opt for RSA because AES-256 provides top-notch security.

Diffie-Hellman and ECDH

Diffie-Hellman and ECDH is a Handshake protocol alternative that offers key lengths of 2048-bits or 4096-bits. The said encryption standard provides perfect forward secrecy to the users without any hassle.

Best Free Encrypted VPN 2021

Fortunately, you can secure your online privacy by using a free encrypted VPN. Meaning there are free VPN services that offer encryption crucial for spoofing your online locations. You can get awareness about the best free VPN that can improve your online security to the next level instantly.

Keep in mind that free VPN services usually do not provide adequate encryption and security. With a free VPN, you might experience data leaks, including your IP address, email address, etc. However, there is one VPN provider that is providing excellent services and encryption for free: ProtonVPN.

ProtonVPN-is-the-best-free-Encrypted-VPN-available

ProtonVPN is a Switzerland-based VPN provider that offers unlimited bandwidth and high-security encryption. It uses the AES-256 encryption standard, which effectively secures user data from leaks or interception. This is why I recommend ProtonVPN as the best VPN for encrypted surfing that you can have for free.

Best Encrypted VPNs for Android

There are quite a few VPN providers available for Android devices. If you own an Android device, you should consider certain factors before opting for the best VPN for encrypted browsing. First, the VPN provider should have good compatibility with Android OS. Second, it should use the most recent and advanced encryption protocols.

The VPN providers that we reviewed in the list above all have the best encryption features. However, all things considered, NordVPN is the best-encrypted VPN for Android that you can have. Not only does it provide great compatibility with Android, but it also uses additional security features like double VPN for maximum protection.

Thus, for Android users, NordVPN is the best VPN for strong encryption. You can also read our blog on the best VPN to learn more about the leading VPN providers in the market.
