Introduction

Virtual Private Network (VPN)

A virtual private network (VPN) extends a private network across a public network and enables users to send and receive data across shared or public networks as if their computing devices were directly connected to the private network.

VPN Types:

1.Site – to – site VPN.
2. Remote access VPN.

Site – to – Site VPN

In contrast, a site – to – site VPN uses a gateway device to connect an entire network in one location to a network in another location. End – node devices in the remote location do not need VPN clients because the gateway handles the connection.

Most site – to – site VPNs connecting over the internet use IPsec. It is also common for them to use carrier MPLS clouds rather than the public internet as the transport for a site to site VPNs. Here, too, it is possible to have either Layer 3 connectivity (MPLS IP VPN) or Layer 2 (virtual private LAN service running across the base transport).

Remote Access VPN

Remote access VPN clients connect to a VPN gateway server on the organization’s network. The gateway requires the device to authenticate its identity before granting access to internal network resources such as file servers, printers, and intranets. This type of VPN usually relies on either IP Security (IPsec) or Secure Sockets Layer (SSL) to secure the connection, although SSL VPNs are often focused on supplying secure access to a single application rather than to the entire internal network.

Some VPNs provide Layer 2 access to the target network, these require a tunneling protocol like the Point – to – Point Tunnelling Protocol or the Layer 2 Tunnelling Protocol running across the base IPsec connection In addition to IPsec and SSL, other protocols used to secure VPN connectivity and encrypt data are Transport Layer Security (TLS) and OpenVPN.

Top-Rated VPN Tools:

2. NordVPN.
3. Hotspot Shield.
4. Surfshark.

VPN Benefits

  1. Enhanced security. When you connect to the network through a VPN, the data is kept secure and encrypted. In this way, the information is away from the hackers’ eyes.

  2. Remote control. In the case of a company, the great advantage of having a VPN is that the information can be accessed remotely even from home or from any other place. That’s why a VPN can increase productivity within a company.

  3. Share files. A VPN service can be used if you have a group that needs to share data for an extended period.

  4. Online anonymity. Through a VPN you can browse the web in complete anonymity. Compared to hide IP software or web proxies, the advantage of a VPN service is that it allows you to access both web applications and websites in complete anonymity.

  5. Unblock websites & bypass filters. VPNs are great for accessing blocked websites or for bypassing Internet filters. This is why there is an increased number of VPN services used in countries where Internet censorship is applied.

  6. Change the IP address. If you need an IP address from another country, then a VPN can provide you this.

  7. Better performance. Bandwidth and efficiency of the network can generally be increased once a VPN solution is implemented.

  8. Reduce costs. Once a VPN network is created, the maintenance cost is very low. More than that, if you opt for a service provider, the network setup and surveillance is no more a concern.

Other things you need to know:

As a future VPN user, keep something in mind: the process of choosing and buying a VPN service should work the same as the process of doing a regular purchase.

Public networks are a real threat. The private networks are not very safe either because your internet service provider can throw an eye on anything you do. You can never be sure if you’re about to connect to a secured network unless you keep your internet activity safe.

So, no matter if you are looking for a VPN to encrypt your traffic while browsing the internet, to bypass geo-restrictions or you’re just the kind of person who likes to save some bucks while buying plane tickets, here’s what you future VPN should provide:

  • Free VPN Trial. Yes, maybe you’ve done some research on your own and saw those Five Best VPN articles all around the web. These articles are useful because are providing you information about VPN services at affordable prices, their performance, and features. When you can test these services by yourself, the experience is even better. That’s why it is important to choose a VPN that provides you a free trial VPN.

  • Speed. Do you have the patience to wait tons of seconds for your page to load while using a VPN? No, who has? Always look for the VPN that improves your internet connectivity, not slows it down!

  • Connectivity and reliability. Before buying a VPN service, you have to make sure that it assures you a safe/without drops connection.

  • The number of servers. The number of servers is an important thing for you to look into a VPN service. Before subscribing to a VPN provider, make sure it provides you a large number of servers around the globe.

  • Apps compatible with various operating systems. I’m sure about one thing – you have more than one device you use to surf the web. There’s a significant probability for your devices do have different operating systems. An important thing that you should keep in mind is that your VPN provider should be able to meet your needs by providing you with apps compatible with as many operating systems as possible.

  • The number of simultaneous connections. We are (almost) always online from more than one device, that’s why the number of concurrent connections is important.

  • Customer support. Not all of us are tech-savvy and, from time to time, even the experienced ones need help and guidance. Choosing a VPN provider with outstanding customer support is mandatory. Look for a VPN that allows you to contact the support via e-mail, support ticket systems, and live chat. You will thank us later for this tip! 🙂

  • Privacy policy. One of the primary purposes of a VPN is to keep your online activities away from the curious eyes of any third party. If you don’t allow your ISP to spy on you, why would you let your VPN service provider do it? Choose a VPN service that has a transparent way of saying and doing things and make sure it won’t keep any connection logs. So, always check their Privacy Policy first, before subscribing!

  • Check their reviews page. We were mentioning above some things about the VPN review websites. Those websites are doing their reviews based on some tests. Wouldn’t it be awesome to be able to find out what the actual customers of a VPN provider have to say about the service and its performance? Here’s a tip: if your future VPN service provider has its own reviews page, throw an eye on it.
