What is VPN?

VPN stands for “Virtual Private Network” and describes the chance to determine a protected network connection when using public networks. VPNs encrypt your internet traffic and disguise your online identity. This makes it harder for third parties to track your activities online and steal data. The encryption takes place in real-time.

Types of Virtual Private Network (VPN)

Virtual Private Network (VPN) is essential of two types:

1.Remote Access VPN

Remote Access VPN permits a user to attach to a personal network and remotely access all its services and resources. The connection between the user and, therefore, the private network occurs through the web, and the connection is secure and personal. Remote Access VPN is beneficial for both home users and business users both.

An employee of a corporation, while they are out of the station, uses a VPN to attach to their company’s private network and remotely access files and resources on the private network. Private users or home users of VPN primarily use VPN services to bypass regional restrictions on the web and access blocked websites. Users conscious of Internet security also use VPN services to reinforce their Internet security and privacy.

2.Site to Site VPN

A Site-to-Site VPN is additionally called a Router-to-Router VPN and is usually utilized in massive companies. Companies or organizations with branch offices in several locations use Site-to-site VPN to attach the network of 1 office location to the network at another office location.

  • Intranet-based VPN: When several offices of an equivalent company are connected using a Site-to-Site VPN type, it’s called Intranet-based VPN.
  • Extranet based VPN: When companies use a Site-to-site VPN type to attach to the office of another company, it’s called an Extranet based VPN.

Site-to-site VPN creates an imaginary bridge between the networks at geographically distant offices, connecting them through the web and sustaining secure and personal communication between the networks. In Site-to-site VPN, one router acts as a VPN Client and another router as a VPN Server because it is predicated on Router-to-Router communication. When the authentication is validated between the 2 routers, only then the communication starts.

Types of Virtual Private Network (VPN) Protocols:


What is it?

An open-source VPN protocol that’s highly configurable for a spread of ports and encryption types. OpenVPN is one of the newer protocols with an initial release in 2001.

What’s it used for?

Third-party VPN clients often utilize the OpenVPN protocol, as OpenVPN isn’t built into computers and mobile devices. It’s become increasingly mainstream for general-purpose VPN use and is now the default protocol most paid VPN providers employ.

Is it fast?

Not as fast as PPTP, about an equivalent speed as L2TP counting on the device and configuration.

Is it secure?

Yes. OpenVPN uses a custom security protocol that relies heavily on OpenSSL, almost like the encryption used on HTTPS websites. Because it is often configured to use any port, it can easily be disguised as normal internet traffic and is therefore very difficult to the dam. It supports several encryption algorithms, the foremost common being AES and Blowfish.

Is it easy to set up?

Suppose you propose setting it up manually, no. However, many native VPN clients from consumer VPN providers make it much easier to put in and run. In those cases, OpenVPN usually requires no manual configuration because the provider’s app takes care of that for you.


What is it?

Layer 2 Tunnel Protocol is the VPN protocol, and it’s usually paired with IPSec for security. Cisco and Microsoft developed L2TP within the 90s.

What’s it used for?

Accessing the web through a VPN when security and privacy are concerns.

Is it fast?

Sort of. There’s some debate out there about whether it’s faster than OpenVPN or not. The typical user probably won’t notice a difference in speed between the 2 . L2TP/IPSec is slower than PPTP.

Is it secure?

Yes, L2TP/IPSec has no known major vulnerabilities. Some experts have voiced concerns that the protocol may need to be weakened or compromised by the NSA, though. The NSA helped develop IPSec.

Is it easy to set up?

That depends. Like PPTP, L2TP/IPSec support is built-in to the latest computers and mobile devices today. The setup process is analogous, but firewalls block the port that L2TP uses. If you want to urge around these firewalls, you’ll get to forward the port, which needs a more complicated configuration.


What is it?

The oldest widely-used VPN protocol, originally developed by Microsoft for dial-up networks. PPTP stands for point-to-point tunnelling.

What’s it used for?

PPTP is employed to connect to the internet and intranet (i.e. accessing a company office building’s internal network).

Is it fast?

Yes. Thanks to the lower encryption standard, PPTP is one of the fastest VPN protocols.

Is it secure?

No. PPTP hasn’t aged well, and lots of security vulnerabilities have arisen over the years. The NSA actively decrypts and monitors PPTP traffic. Albeit it normally uses 128-bit encryption, it effectively offers no security benefits.

Is it easy to set up?

Yes. PPTP is the common protocol built into many computers and mobile devices today, making it one of the simplest–if not the simplest–to find out manually.


What is it?

Secure Socket Tunneling Protocol was developed by Microsoft and first built into Windows Vista. The proprietary (read: not open-source) protocol works on Linux but is primarily a Windows-only technology.

What’s it used for?

Not much. A couple of hardcore Windows fans could employ SSTP because it comes built-in, but it’s no real advantages over OpenVPN. It’s better than L2TP for getting around firewalls without a sophisticated configuration.

Is it fast?

About an equivalent as OpenVPN.

Is it secure?

Yes, assuming you trust Microsoft (questionable). It’s usually configured using strong AES encryption.

Is it easy to set up?

Manual setup is fairly easy on Windows machines. Macs won’t run it and doubtless never will. Linux and a couple of other systems will have a harder time.


What is it?

Internet Key Exchange version 2 isn’t exactly a VPN protocol but are often treated intrinsically. Microsoft and Cisco had jointly developed it.

What’s it used for?

It’s especially useful for mobile devices on 3G or 4G LTE because it’s good at reconnecting whenever the connection drops out. This will happen when the user drives through a tunnel and temporarily loses service or switches from the mobile wifi connection. Support for IKEv2 is made into Blackberry devices.

Is it fast?

IKEv2 throughput is like OpenVPN, but one advantage is that it establishes a connection much quicker.

Is it secure?

Yes, again, if you trust Microsoft. IKEv2 supports several levels of AES encryption and, like L2TP, uses the IPSec encryption suite. Some open-source versions also are available for those that like better to avoid Microsoft’s proprietary version.

Is it easy to set up?

IKEv2 isn’t widely supported, except for compatible devices; it’s quite easy to line up.


What is it?

Internet protocol security, or IPSec, maybe a protocol used for several purposes: VPNs. It operates at the network level against the appliance level (used by SSL).

What’s it used for?

IPSec is usually paired with other VPN protocols like L2TP to supply encryption, but it also can be employed by itself. It’s frequently used for site-to-site VPNs, and lots of iOS VPN apps also utilize IPSec in lieu of OpenVPN or another protocol.

Is it fast?

IPSec is usually considered faster than SSL, but your results may vary, counting on configuration and intended use.

Is it secure?

Yes, IPSec is secure, although, in 2013, the Snowden leaks revealed that the NSA was actively working to insert vulnerabilities.

Is it easy to set up?

Depending on what you propose to use it for, configuring an IPSec VPN are often complex. It shouldn’t be a drag for the typical user with an iPhone just trying to attach to their VPN provider’s servers.


What is it?

Transport Security Layer (TLS) and its predecessor secure socket layer (SSL) are the foremost common cryptographic protocols in use today. Any time you hook up with an HTTPS website, your connection to the server is protected with SSL. It’s utilized in some VPN protocols but isn’t in itself a VPN protocol.

What is it used for?

When it involves VPNs, OpenVPN’s encryption is made on the OpenSSL library, and OpenVPN is taken into account an SSL VPN.

SSL is additionally wont to create HTTPS proxies, which are happened as VPNs by some companies. These are often advertised as browser-based VPNs that run as Chrome or Firefox extensions and don’t provide the complete security benefits of a real VPN.

Is it fast?

This depends more on the VPN protocol and, therefore, the level of encryption used.

Is it safe?

To maximize security, TLS is newer and better protects against attacks than SSL.

Is it easy to set up?

SSL VPNs are generally considered easier to configure than IPSec VPNs for remote client connections.


What is it?

Wireguard may be a secure VPN tunnel protocol that aims to enhance the opposite protocols during this list in terms of speed, simple deployment, and overhead. It’s the most recent protocol on this list.

What’s it used for?

Wireguard remains in development, but it’s available for several platforms. It’s lightweight enough to run on embedded interfaces and appropriate for containers like Docker all the high to high-performance devices and networks.

Wireguard is finding its way into more and more VPN apps lately, largely because of speed improvements over OpenVPN and IKEv2.

Is it fast?

Yes. Wireguard does away with tons of the bloat found in other protocols and runs from the Linux kernel to enhance speed.

Our speed tests have shown massive improvements across almost every provider that has adopted Wireguard, with download bandwidth doubling and, in some cases, tripling what was previously achieved by other protocols.

Is it secure?

Yes, though we remind readers that Wireguard remains in development. Wireguard uses state-of-the-art cryptography, can easily be audited and uses an idea called “cryptokey routing” to handle network management and access control in lieu of complicated firewall rules.

However, Wireguard assigns IP addresses statically and not dynamically, which suggests some user data must be stored on the server.

Is it easy to set up?

Yes, though it’s not widely implemented yet. The creators liken Wireguard to configuring SSH, a really simple secure protocol. It allows roaming between IP addresses. Wireguard’s website states, “There is not any got to manage connections, worry about state, manage daemons, or worry about what’s under the hood.”

Why does a fast VPN protocol matter?

Even though speed shouldn’t be the deciding factor, a slow VPN will discourage users and can, therefore, quickly be abandoned. You don’t pay top dollar for a quick internet connection, only for the VPN to slow it down. Or, once you have a slow connection, you don’t want your VPN to form even worse. But speed is usually a trade-off with other characteristics, just like encryption strength and security. And therefore, the speed also depends on factors outside of the protocol, just like the distance to the VPN server and the essential speed of your internet connection. Employing a VPN will never make it faster.

Security and privacy

This will be the deciding factor for several users once they are close to choosing a VPN. It must be said that the seller is a minimum of as important here because of the protocol. After all, what good may be a secure protocol if it seems the seller is willing to hand over your data at the primary request? So, if you hear people ask what’s better than OpenVPN, for instance, the solution is that it depends on what you’re trying to find exactly. Many protocols are capable of comparable speeds and levels of secure encryption.

Ease of use

We’ve made a point often within the past that security and privacy software that’s hard to line up or difficult to manage often misses the target. Misconfigured software doesn’t do what it potentially can do for the user, so it’s a waste of your time and money. We’ve seen cases where the user would are safer employing a free VPN or none in the least.

User Questions:

  1. Why is VPN paid?

Paid VPNs offer you unlimited access to their entire server networks, which are often gigantic and span the whole world. Therefore, you’ll have access to more geo-restricted services and websites. As a general rule, the more servers, the higher for unblocking sites and for connection speed.

  1. Is it better to buy a VPN?

The short answer to the present question is yes, investing during a VPN is worthwhile, especially if you value online privacy and encryption while surfing the web . … VPNs conceal an IP address to form actions on the web almost untraceable.

  1. Is changing your VPN illegal?

Are VPNs legal everywhere? No. VPNs are perfectly legal to use within us, and in most western democracies like Europe. that does not mean that you are liberal to conduct illegal activities with a VPN enabled – you are still committing an illegal act.
