With all the news of governments getting around tough encryption, and the (justified) ever increasing paranoia that pervades on the internet, it’s 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, and with it, higher numbers in their encryption stats. Whether higher numbers actually make much difference is a matter of some discussion – if 128-bit AES is unbreakable, and should remain so for the rest of our lifetimes, then why go for 256-bit and incur a loss of speed? Regardless, if high-end encryption is what you want, there are companies that will provide it for you.

That being said, there are some 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 standard of encryption also offer other privacy protection such as zero logs, shared IPs, Bitcoin payment etc. So let’s take a look at which VPNs offer the best encryption.

That aside, VyprVPN is a Switzerland based VPN provider that offers better than average speeds, proprietary technology, exclusive features, and no usage logs. VyprVPN offers a free 3-day trial for users looking to sample before they commit.

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 128), and is likely to remain so for a very long time.

In other words, levels of encryption higher than 128-bit are unnecessary, and can, in theory, slow down a VPN’s service as its servers have to dedicate more processing power to performing the extra (2128 times the length) math necessary to encrypt and decrypt the keys to 256-bit. However, as real-world tests such as this one demonstrate, the impact can be pretty minimal, and it is unfair to criticise VPNs for trying to match the demands of their customers.

It is important to remember that, because of the inordinate amount of time required to brute force AES-256, it’s very unlikely anyone would even try.  Organisations seeking encrypted information are far more likely to be looking for weaknesses in the algorithm itself by subpoenaing companies to decrypt what they want, keylogging, threatening individuals, the list goes on.

Users should be aware that something as avoidable as a DNS leak will remove the P from VPN.

Check our guide for a more detailed look at encryption .

Whilst all of the VPNs listed above use very secure encryption, there are protocols used by some providers that are simply insecure. PPTP, for example, has definitely been broken. We only recommend using OpenVPN with AES encryption (Blowfish is known to have weaknesses).

All of the options in this list are solid VPNs that offer extremely strong encryption and plenty of other privacy features. If you have any comments or questions, be sure to leave a comment.

      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.

  1. Mona :

    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?
