What is a VPN?
Different Types of VPN
Types of VPN Protocols
Activating a VPN (Virtual Private Network) is the only way to keep yourself safe in the digital world.
If you don’t take the necessity of a VPN seriously enough, you may have to pay for it. We already discussed that in our previous blog “Top 7 Uses Of Android VPN App“.
Now tell us, wanna take the risk?
Of course not!
It’s mandatory on every phone to shut down the interests of those who want to run their eyes over your personal information.
We introduce you to SPL VPN, one of the best and most reliable VPN providers to satisfy your digital life.
This is the best option with servers spread around the world to surf quickly, seamlessly, and safely without being exposed to hackers’ eyes.
Recounting it again for our friends who don’t know what VPN is…
What Is A VPN?
A VPN (Virtual Private Network) promises to extend your private network across a public network.
You’ll be able to send/receive data over the shared or public network as if your device was connected directly to the private network.
Millions of people around the world use a VPN to establish a connection to unblock websites restricted by their countries.
They use different types of VPNs to access streaming platforms like hotstar. Apart from enjoying the benefits of streaming, VPN is used for playing games like Pubg.
It creates an encrypted connection known as a VPN tunnel.
All of the internet traffic and communication will be passed through it.
What’s the result?
So, your data will be secure and private!
Many people around you have enabled the VPN on their phones.
Still, there’s a problem!
A list of providers is ahead that do not keep the promises.
“But the label of loyalty from SPL VPN has been exposed to people just by ensuring servers around the world and keeping your privacy extremely important”.
SPL here’s to more hearts!
Different Types of VPN
There are two types of VPNs you must know about!
- Remote Access VPN
- Site-to-site VPN
Let’s have a look at the clear picture on it!
✅ Remote Access VPN
With this type of VPN, a user can connect to a private network and access all its services and resources remotely.
The user’s connection to the private network is established over the Internet.
Do you know!
SPL VPN promises that it’s secure and private.
A Remote Access VPN is 100% beneficial to both home and business users.
Lemme give you all an example!
If an employee in your company is out of the station, they can easily connect to your company’s private network using a VPN.
They are able to remotely access files and resources at a faster speed.
Private and home users of VPN purely outweigh regional barriers on the Internet just by having the best services like SPL VPN.
Simple access to the blocked websites!
VPN services are mostly used by those who are concerned about their online privacy and security.
So, you too?
Let’s see what the second among the different types of VPN is!
✅ Site-to-site VPN
We can also call the Site-to-site VPN as Router-to-Router VPN.
It is mostly used in large companies.
Companies or organizations with branch offices at different locations connect from the network at one office location to the network at another office location using Site-to-site VPN.
Let’s divide this VPN service into two again!
👉🏻 Intranet-based VPN
Here several offices of a company are connected by site-to-site VPN.
👉🏻 Extranet based VPN
Here the companies connect to another company’s office with a site-to-site VPN.
The Site-to-Site type of VPN creates an imaginary bridge between geographically distant offices. That’s how many expanding businesses there are!
They are spread in many parts of the world.
So, VPN is a profession-saving thing for the globe.
Maintains 100% private and secure network communication.
Because Site-to-Site VPN is based on router-to-router communication, one router functions as a VPN Client and the other acts as a VPN Server.
Only after the authentication between the two routers has been verified does communication begin.
Types of VPN Protocols
Not all VPNs are created the same way.
According to the VPN protocol, there will be differences in speed, ability, and security/privacy matters for each.
We list the most important types of VPN protocols here.
You can choose the best!
It’s a VPN protocol that has a great reputation and guarantees a high degree of safety.
So, it is used by many VPN providers. It drives on either the UDP or TCP internet protocol.
The former ensures that your data is delivered in its entirety and in the proper order, whereas the latter prioritizes faster speeds.
The top qualities of OpenVPN are open source, security, versatility, and the ability to bypass most firewalls.
Open source means transparent behaviour!
Anyone can examine the code for hidden backdoors or weaknesses that could jeopardize the security of your VPN.
With the label of security, it drives almost all encryption protocols.
OpenVPN is used with an array of encryption and traffic protocols, configured for several uses, and maintains security as you need!
Let’s forget the compatibility of firewalls.
With this VPN protocol, you can bypass the firewall.
By establishing an authenticated and encrypted network connection, this protocol builds the foundation for the best and most secure VPN connection.
The developers of IPSec/IKEv2 are Microsoft and Cisco to make your experience faster and more secure.
Do you know what the highlight of this protocol is?
To provide comprehensive VPN coverage, IKEv2 uses other IPSec tools as part of the IPSec internet security toolbox.
The Mobility and Multi-homing Protocol is an IPSec tool.
IKEv2 usually uses this, which confirms the best VPN connection as you move between the network connections.
IKEv2 will be the best, most stable, and most dependable protocol for your phone.
IKEv2 works with top encryption algorithms as part of the IPSec suite and is labeled as the most secure one!
It only takes a little bandwidth once active!
Besides that, it helps you connect and communicate ghastly with its NAT traversal.
It will also aid you get through the firewalls.
WireGuard is a popular and widely used communication protocol that will be available for free and offer open-source software.
It implements encrypted VPNs and is designed with the purpose of being easy to use low attack surface, and blazing fast performance.
State-of-the-art cryptography is used by this protocol, which is a real boon for them to outshine the masters like IPSec/IKEv2 and OpenVPN.
SPL VPN is using this VPN protocol to let you experience the difference in the digital universe.
So, we gift you a free and open-source as you can see the code.
It will definitely help you deploy, audit, and debug!
“SPL VPN, with its WireGuard protocol, is trying to bring the most modern changes to your experience at the fastest speed possible”.
In all of the protocols, WireGuard has only 4000 lines of code.
Yeah! The leanest!
Do you want to compare the quality?
OpenVPN code has 100 times more lines than that of WireGuard.
Secure Socket Tunneling Protocol is created by Microsoft.
It is a secure and capable VPN protocol.
Still, think about the final decision over it, just because it is experimental in industry.
And another con is that, since Microsoft owns it, the code will not be available for security researchers to test.
You must evaluate whether this protocol is useful for your needs.
This is a primary product of Microsoft, but it is also available on other systems.
With such a large market share, as owned by Microsoft, you can think that the Windows OS will either support SSTP or have it built-in.
The AES-256 encryption protocol is supported by SSTP to pin your security, and it can also get through many firewalls without making any complaints about your communication.
Layer 2 tunnelling protocol (L2TP) does not provide any encryption or authentication but creates a connection between you and your VPN server as a VPN tunnelling protocol.
Encrypting your traffic depends on tools like IPSec and keeping it secure.
Do you know?
It’s widely available!
Most modern consumer systems provide L2TP.
Therefore, the admin can find instant support and run comfortably without any difficulty.
These will certainly be safe because they accept different encryption protocols.
Point to Point Tunneling Protocol began to come into use in 1999.
Firstly, it was designed to tunnel dialup traffic.
It has a number of security flaws and uses some of the weakest encryption protocols of any VPN protocol on this list.
So, it’s not much recommended!
It is fast but outdated, with minimal security.
That’s why it’s so popular among those who want to set up a VPN at home to get access to geo-locked content.
Since it was made many years ago, it has become a bare-minimum standard for tunneling and the process of encryption.
PPTP will be easily blocked by firewalls and cracked by the NSA.
Which protocol do you think is best for you?
