VPNプロトコルの比較 – PPTTとオープンVPNとPPTPとL2TP / IPSec、SSTPとIKEV2
#L2TP / IPSEC
ただし、IPSec暗号化は、IPSec暗号化を使用するユーザーにセキュリティとプライバシーを提供します。ほとんどのVPNおよびオペレーティングシステムには、L2TP / IPSecが組み込まれています。このプロトコルの賛否両論は次のとおりです。
これは市場で新しいプロトコルの1つです：OpenVPN。これはSSLv3 / TLSv1プロトコルと共にOpenSSLライブラリを利用します。 OpenVPNプロトコルは、比較的安全と考えられる128ビットのBlowfish暗号を利用しています。しかしながら、既知の問題が存在する。ブローフィッシュの作成者でさえ、人々が代替手段を使用することを示唆しています。
The various VPN protocols out there have been created to cover different needs and requirements. So it is best to first realize what your priorities are and then go ahead with selecting the perfect option for you.
You need to ask yourself:
- what it is you value while using a VPN connection online?
- Do you want total privacy?
- Are you wanting the fastest speed out there?
These are all answers that will affect which protocol fits your needs. So, what is the best VPN protocol for you and your special needs?
First Of All Realize What Your Priorities Are And What Features Matter To You Most
I makes sense to make a list with the features that matter to you the most. You cannot expect to get thorough encryption with top notch speed, after all. What a VPN protocol lacks, another one boasts – and vice versa of course!
So in the VPN protocols comparison following right below, you will be able to check these features and decide accordingly. Let’s have a look at the VPN protocols that meet each criterion and even exceeded one’s expectations regarding encryption, reliability and speed.
VPN Protocol Comparison – PPTT vs OPEN VPN & PPTP vs L2TP/IPSec, SSTP and IKEV2
#PPTP: Point to Point Tunneling Protocol
This is one of the oldest protocols on the market. However, that does not mean that this is the best just due to its age. This is the standard protocol that you would see with just about any VPN that you utilize.
A few pros of this protocol:
- Super easy to set up manually. Do note that when using a VPN connection, this is automatic and not something you need to worry about.
- Requires a low computation overhead, meaning it is quick
While these are great benefits, you do need to realize that there is one huge drawback that comes to mind when talking about PPTP, and this is the fact that it is not considered that secure. And it has been shown to be compromised by the NSA. Meaning that as long as the person can decrypt, more than likely they can access your information with ease.
#L2TP / IPSEC
This is an interesting protocol set up. Why is this? VPN protocol L2TP on its own is not secure at all. In fact, it does not provide encryption at all.
However, when IPSec encryption works along it, they provide security and privacy for those who use it. Most VPN’s and operating systems are going to come with L2TP/IPSec built into them. The pros of this protocol include:
- Considered decently secure
- Is easy to set up manually (if you use a VPN connection you don’t need manual set up)
- Faster than OpenVPN
However, keep in mind that this protocol may have been compromised by the NSA, though this has not been proven. In either situation, many believe that if the NSA has not compromised this completely, it has been weakened. In addition, when using this protocol it could struggle with trying to get passed those firewalls that may be in place.
This is one of the newer protocols on the market: OpenVPN. This utilizes the OpenSSL library along with SSLv3/TLSv1 protocols. The OpenVPN protocol does utilize a 128-bit Blowfish cipher, which is considered relatively secure. However, there have been known issues. Even the creator of Blowfish suggests people use an alternative.
Most VPN providers now use OpenVPN with AES-256 instead of Blowfish. AES-256 is the encryption system used even by the US government and when working along OpenVPN the security level is very high.
The speed of OpenVPN varies from user to user. Why is this? The speed is going to greatly depend upon the level of encryption that is being used. Some pros of this protocol:
- It is one protocol that can be configured to almost anything
- Very secure, can easily bypass firewalls
- Uses a wide variety of encryption algorithms giving you more control
However, keep in mind that this is harder to set up than other protocols on the market, and it has to use a third-party software in order to be used, which can open up your device to a wide range of issues.
With this third party software it opens up your device to new issues and threats. There is nothing that states this third-party software is going to be completely safe to use. It is not uncommon for this software to attach malware or viruses into the devices that download this.
However, if you use OpenVPN through some of the best VPN connection on the market you don’t have to worry about both setting it up and possible threats for your device. The VPN will set OpenVPN completely and their software are 100% secure.
#SSTP: Secure Socket Tunneling Protocol
With the majority of this protocol owned by Microsoft, this protocol does not inspire many people to feel confident in being secure online. After all, Microsoft has been known to easily work with the NSA on providing data. Therefore, those who want to remain private may find it impossible to do with this protocol.
Aside from this however, it does offer some benefits:
- Easily integrates into devices
- Bypasses most firewalls
- Comes with Microsoft support
Those who do use this protocol find that due to its stability, it is often easier to use than the other protocol choices on the market.
#IKEv2: Internet Key Exchange (version 2)
This is one of the many protocols that is based on the IPSec technology. This was developed by Microsoft and Cisco together. What makes this protocol stand out against the others on the market, is its ability to reestablish a VPN connection when internet has been lost. Most people who utilize this protocol are going to be using this on mobile devices, especially via Blackberry devices.
A few of the pros about this protocol:
- Faster than the other protocols out there, however, it is really only for use with mobile devices
- Secure as it utilizes AES 128, AES 192, AES 256 and 3DES ciphers
- Super simple to set up
Fastest VPN Protocols – Which Protocol Offers The Best Speed?
One of the major characteristics that attract attention when it comes to VPN protocols is their speed. It makes sense why people are interested in finding a fast VPN protocol to connect to.
When connecting to a VPN, the connection speed should be rather fast. No one wants to deal with a connection that is comparable to dial up internet speeds.
The Internet has made substantial progress and now people connect and enjoy superb conveniences. It is only fair that they connect at a decent speed! Especially when Internet users focus on gaming or live streaming, speed is essential.
As far as speed is concerned, one of the fastest VPN protocols is none other than PPTP. With 128-bit encryption, it requires less time to complete. Of course it is basic encryption and some people are appalled by the fact that there are gaps in the security level.
In fact, PPTP is relatively easy for the government to hack into and watch those who use this. Thus, it may be great on speed, but it falls behind when it comes to security. A 128-bit encryption cannot be broken by your average hacker. However, with the speed of computers that the NSA has, along with the knowledge that the NSA has, breaking a 128-bit encryption speed is getting closer than ever before. Plus, keep in mind that most government agencies are utilizing a 256-bit encryption key to keep their data safe.
But PPTP is still the default – native VPN protocol in many cases, working fine with most OS and devices. It is fast, as well as easily supported. Instead, OpenVPN might delay a bit due to the advanced encryption that it offers.
For those who use a Blackberry, they will find that IKEv2 is a fast protocol. But, it is only to be used with Blackberry or Windows phones, thus it is a bit restrictive.
L2TP/IPsec is also relatively slower as a protocol, encrypting data twice and thus requiring more CPU. However, it offers a level of security that many people are eager to have when they are online.
Finally, there are cases when VPNs lead to ISP throttling. ISP throttling is when your ISP(Internet Service Provider) for some reason slow down your connection. This means that you cannot expect to get great speed when connecting to a VPN, no matter what VPN protocol you use. Well, in these cases you can restore your speed by using Chameleon VPN.
It should be noted that the Chameleon VPN protocol is not a protocol in the traditional sense of the word. It is classified as a proprietary protocol.
Chameleon VPN does utilize 256-bit encryption, which is considered a rather protective encryption rate. So how does this work?
The Chameleon VPN Protocol scrambles the data of the connection. In this way, Internet sites cannot tell that a connection is VPN protected. This was introduced by VyprVPN as a way to help those located in nations like China to still use a VPN to access a free Internet.
A restriction of Chameleon VPN Protocol is that it does not work with any iOS devices. And it is also only available with the Pro and Premier versions of VyprVPN.
Most Secure VPN Protocols – Which Is The Best?
Security is a precious commodity nowadays in the digital era. Therefore, Internet users are alert and try to come up with the safest VPN protocol in the market. Of course, the very core of VPN is relevant to security boost. Encryption offers significant improvement security-wise.
After all the information that we have learned after Edward Snowden released his findings online, being secure online is a necessity. Snowden found information that shows how the government hacks into consumer’s computers bypassing the numerous security gates that may be in place. Plus, when you factor in the number of hackers and identity thieves that lurk online for someone who has their defenses down, staying secure online is a necessity!
Security Is A Precious Commodity In The Digital Era
But not all VPN protocols claim to be the safest – and if they do, not all of them live up to their standards. Therefore, it is important to look at how they are encrypting signals, and how strong of an encryption level the protocol is utilizing.
Perhaps the most secure VPN protocol out there to this date is OpenVPN. Reaching 256-bit encryption, it authenticates data with digital certificates and provides an integrated solution for those who value anonymity.
It is reliable and stable, preventing any data leaks and other security hazards. It is supported on most OS and devices now. Even when it is not offered automatically, you can download it and start using it without any hesitation.
Another VPN protocol that boasts thorough encryption is L2TP/IPsec. Although it may run a bit slowly (when compared to the less secure PPTP and the equally safe OpenVPN), this is a truly secure option among VPNs that comes at 256-bit. It checks data integrity and offers encryption twice. It is native in most cases and it is truly reliable.
Last but not least, Chameleon VPN is secure and lacks nothing in terms of efficiency and stability.
Simplest VPN Protocol – Which Is Easiest To Use?
Apart from the fastest VPN protocols and the most secure VPN protocols, there is another factor to consider. Simplicity is sometimes of the essence and it should not be underestimated. After all, you can have all the security and speed in the world, but if the protocol is too hard to understand how to use, it will offer you little benefit.
When an Internet user seeks simple setup, PPTP is definitely the answer.
It might not be the safest option to use at all times, but when strong encryption is not necessary PPTP manages to excel.
OpenVPN can be really baffling and particularly when it is not native to the OS or device you use. So for newbies and non-tech literates, PPTP is a great start.
A nice middle option between PPTP and OpenVPN is L2TP/IPsec, which offers decent security and speed, and a set up that is not complicated by any means.
In any case, when you use a VPN protocol set through a VPN provider, to switch from one to the other is just a matter of a click. The software will automatically take care of all the technical issues.
