5 Best VPNs for Strong Encryption

With all the news of governments getting around tough encryption and the (justified) ever-increasing paranoia that pervades the internet, it is understandable that many people want high-grade encryption as part of their VPN package.  As a result, it is becoming more and more common for providers to offer higher and higher levels of security. 

Whether the most robust security implementations are absolutely necessary is a matter of some discussion - if 128-bit AES is unbreakable, and should remain so for the rest of our lifetimes - why go for 256-bit and incur a loss of speed? Regardless, if high-end encryption is what you want, there are companies that can provide it for you.

That being said, there are other important things to take into consideration regarding encryption, such as key lengths, known weaknesses in protocols etc. Which we will look at later in the article. The upside is that a lot of the VPN companies that employ the highest standards of encryption also offer other privacy protection such as zero logs, shared IPs, Bitcoin payment etc. So, let's dive in and take a look at which VPNs offer the best encryption...

Editor's Choice

NordVPN is a secure VPN with a strong privacy policy.  Encryption is handled with an AES 256 cipher for data and control, RSA 2048 handshake, and SHA-256 authentication. Perfect Forward Secrecy is delivered via a DHE-4096 key exchange. Their servers are also protected by firewalls and SSH connections are used. Should you run into any issues, Nord's FAQ section is extensive and clear, and any details you can't find there will be quickly provided by the staff on their 24/7 live chat system - When Dimitri reviewed the service he waited no longer than a few minutes for his query to be resolved. NordVPN also offers a free "Emergency VPN" service for those living under authoritarian rule to protect themselves from religious/ thought/ press police.

4. PrivateInternetAccess

BestVPN.com Score 9.5 out of 10
Visit Site  

Private Internet Access always scores well when it comes to VPN security. This is because it provides some of the strongest encryption options available on the market. For those that require the strongest levels of all OpenVPN can be toggled to have an AES 256 cipher, SHA256 for authorization, and a handshake of RSA 4096. Perfect Forward Secrecy is implemented with a choice of DHE or ECDH; both are secure. With a strong privacy policy, a good privacy blog, and a solid reputation this VPN can be trusted to be reliable. However, complaints about slow customer support may put VPN newbies off. Despite this slight drawback, there can be no doubt that for many people this VPN provides robust security at an affordable price.

Great encryption and fantastic customer support makes PrivateVPN a great option. PrivateVPN uses military grade OpenVPN encryption so you can be sure that your data is kept safe from ISPs, they also keep no logs which a major benefit. However, it is slightly weaker than some of the VPNs above (but for the price is incredible and cannot be hacked). PrivateVPN has servers in 56 countries including the UK, USA and Hong Kong, so you wont struggle to unblock content from around world. As well as strong encryption PrivateVPN is really fast, so you can stream in HD. Although PrivateVPN offers a range of great features it's surprisingly cheap, and they also offer a 30 day money back guarantee!

Considerations for VPN encryption

All the above providers offer AES-256 bit encryption, which is unbreakable by brute force attacks using today's technology (as is AES-128) and is likely to remain so for a very long time.

In other words, levels of encryption higher than 128-bit are technically unnecessary at this moment in time. What's more, stronger encryption than is absolutely necessary can, in theory, slow down VPN connection speeds (because its servers have to dedicate more processing power to implement the longer cipher. 

However, as real-world tests prove, the impact can be minimal if the VPN is setup properly - and because all the VPNs in this guide manage to provide excellent speeds and stronger encryption - you really can't complain!

It is important to remember that because of the inordinate amount of time required to brute force AES-256, it is very unlikely that anyone will even try.  Organisations (like the NSA) are far more likely to serve VPN firms with a warrant and gag order that forces them to hand over logs. Luckily, however, all of the VPNs in this guide keep zero logs and have a proven track record of providing privacy to their subscribers.

Users should also be aware that something as avoidable as a DNS leak will destroy a VPN's security. That is why it is essential to subscribe only to a world-class VPN that has been thoroughly tested. Rest assured that none of the VPNs in this guide suffer from DNS leaks, IPv4 leaks, or the WebRTC bug. Check our guide for a more detailed look at encryption .

Whilst all of the VPNs listed above use secure encryption, there are protocol options used by some providers that are still insecure. PPTP, for example, has definitely been broken. At BestVPN.com, we only recommend using OpenVPN with AES encryption (Blowfish is known to have weaknesses); so stay away from other encryption options unless you know why you are using them.

All of the options in this list are solid VPNs that provide extremely strong encryption and plenty of top-notch privacy features. If you have any questions, be sure to leave a comment below, we are always happy to help!

      Hi lol, According to its privacy policy: "No we do not keep logs of user activity including user access, DNS requests, timestamps, bandwidth usage or user’s IP addresses. We do monitor general overall traffic of the server and number of connections in which the server is pushing through but not on an individual level." It goes on to say : "However as per our policy, if we do notice any unusual activity on our servers via our general monitoring (high bandwidth loading, high number of connections or cpu usage) or receive a specific complaint (hacking/spam) we may turn on logs temporarily to identify abuse of our services (such as DoS or spamming through our servers)." But this is true of any VPN service.

    I think Windscribe should be on the list. It has very strong encryption, a user friendly client with a reliable kill switch. Privacy is good too, and P2P is allowed. Why not expand your lists to 10 best vpns in each category?
