How to choose the best VPN service?

The acronym VPN stands for Virtual Private Network, or VPN. It is formed by a group of computers that connect using a public network: the internet. Some companies use VPNs to connect distant data centers or even to have their employees working at home or even from anywhere they are in the globe. VPNs are extremely handy in today’s generation, after all it can also work as an extra protection for those who would not like to have their data stolen from third parties.

If you are a worker.

If you are a worker you definitely need to have flexibility with protection. Having your antivirus and some software will not be enough. You could save money and time by having the best VPN service (hopefully provided by your company). Staff can connect to VPNs to access the local network of the company without being physically there. Is also an excellent way to protect and encrypt your internet communications in untrusted public networks such as WiFi networks of airports. This is also 100% necessary for businessmen.

If you want to be safe or simply low profile.

That is, basically, a VPN enables remote access to resources on a local area network, even if you’re not physically connected on that network. Also serves to ensure protection during the exchange of information across the internet in public networks.

When you connect to a VPN, generally performs a client on your computer or click on a special link on a Web site, log in with your credentials and each machine at each end verifies the authenticity of another. This is a different process to using a CGI proxy, and usually involves a piece of software being executed on your local machine. When the VPN is on you will be protected since your information will not be stolen from you. This is also a good thing for those who would like to use torrent downloading services, that way they will not have to face charged in the future for being caught up doing something they technically should not.

The bottom line.

When occurs the confirmation, your internet communication is encrypted and protected from interception. This is the main detail of a VPN: the security that it provides for your internet browsing, avoiding that your data be visible to unauthorized persons. Therefore VPN service is an excellent technique/ technology today because it can protect us from so many cybercrimes that most of the times are not even punished by the local authorities (some countries do not even have laws regarding cyber safety).

Can a VPN Allow You to Circumvent Regional Restrictions?

Are you having trouble accessing a website based in another state or country? Many organizations use regional restrictions, such IP-based geolocation, to prevent internet users from other states and countries from accessing all or certain parts of their website. Your own organization may have implemented such as restriction, making it impossible for you to access your own website when you are away in a foreign country. If this is the case, then VPN may be the answer you are looking for.

But first, let’s find out what IP-based geolocation means. Every device connected to a computer network, including the internet, is automatically assigned a unique address consisting of a string of numbers punctuated by full stops. This is called an IP address. IP stands for internet protocol, if you didn’t already know. Your computer’s IP address doesn’t just uniquely identify your computer on the internet, it also gives away your geographical location.

When you try to log into a website, it immediately knows where you are from by analysing your IP address. If it has implemented regional restriction, it will block you. There are several ways to circumvent the restrictions, including the use of anonymous proxies and VPN. Proxies are not very reliable and, in any case, when will you have the time to find a proxy service provider when you are visiting a foreign country?  But if your company has implemented a VPN, you will have no trouble accessing any website.

A VPN, which is short for Virtual Private Network, is a method for adding an impenetrable layer of security and privacy when connecting your office network or home network to the internet or a public network. It makes the connection between your private network and the internet so seamless that you will not experience any difference in the way you access information and resources from the way you access the information and resources on your network.

When connecting to the internet or public network, the VPN establishes a point-to-point connection using a VPN networking protocol such as PPTP, L2TP and SSL protocol. These protocols allow your network to communicate with the internet. Using these protocols, you can connect your private network with any other networks via the internet. For example, you can connect your office network with your home network.

Now to go back to the point, when you use a VPN, it reroutes all your internet traffic through itself.  This means that your IP address will become invisible to the destination server, which will treat you just like any other visitor from the area where the server is located. Thus, VPN makes it possible for you circumvent regional restrictions, such as IP-based geolocation.

What Are The Most Popular VPN Protocols?

A virtual private network (VPN) is a method that allows you to connect your private network, such as your office LAN or home LAN, securely to the internet and to each other via the internet. It creates a virtual network that shields your physical network from hackers, malware and other security hazards emanating from the internet. A VPN connects your private network to the internet by establishing a virtual point-to-point connection using a networking protocol.

 

There are several networking protocols you can choose from for your VPN. Some of the most popular are:

 

  • Point-to-Point Tunneling Protocol (PPTP)

 

A Point-to-Point Protocol (PPTP) is a set of communication rules that allow an organization to implement a virtual private network (VPN). It is supported by almost every operating system, including Windows and Mac OS. However, lack adequate encryption and authentication features make it the least secure networking protocol.

 

  • Layer 2 Tunneling Protocol (L2TP)

 

A Layer 2 Tunneling Protocol (L2TP) is a set of communication rules that is used to support a VPN. It’s called a tunneling protocol because it encapsulates a another protocol, the Internet Protocol Security (IPSec), to carry a payload over an incompatible network. The L2TP relies on IPSec to provide encryption and confidentiality as it does not provide its own.

  • Internet Protocol Security (IPSec)

Internet Protocol Security (IPSec) is a set of protocols (called a protocol suite) that used cryptographic security services to provide security to IP communications during communication sessions by authenticating and encrypting the IP packets. It is used for protecting data during host-to-host and network-to-network communication. It is a highly secure network protocol.

 

  • Transport Layer Security (TLS)

Transport Layer Security (TLS) and its predecessor, Secure Socket Layer (SSL) protocol, are the most widely used security protocols on the internet and internal networks today. Because of their exceptionally high security level, they are used when a web browser wants to send sensitive data, such as a credit card number, to a web server.  The use of TLS and SSL on a VPN makes it virtually impregnable.

 

  • OpenVPN

OpenVPN is a freely available open-source VPN protocol that is based on the SSL code. It is great for creating point-to-point and site-to-site connections. It is secure and doesn’t have any connection issues. It is also capable of traversing firewalls and network address translator (NATs). However, it requires a client to be installed as it is not natively supported by Windows, Mac OS X and mobile devices.
