What is VPN service?

In this day and age, data access is important for improved productivity and to give timely responses to issues. There is a lot of scope for virtual work and troubleshooting, but a major concern is the integrity of information transmitted over the web. Using VPN is one of the ways to achieve a safe and sound connection. But, what is VPN and how safe is it to use the service?

VPN explained

To know what is VPN or virtual private network, it is important to get a feel of how it works. Installing a VPN technology involves using hardware or software. Basically, encrypted data is transmitted through remote servers making it accessible to authorised users only. Thus, a user name and password for each computer and individual is set up. With the VPN, the server is anonymous to others on the web and reduces the chances of intercepting information. VPN technology enables users to connect and share files securely directly from their browsers using a safe connection.

Types of VPN

There are 2 kinds of VPN such as:

  1. Intranet - dedicated server in an organisation and remote access is done through an authentication process.
  2. Extranet - connects external servers outside of an organisation or business for file and data exchange. Users are also verified with unique passwords.

Key benefits

  1. Remote access through a web browser - For businesses, corporate resources and files are accessed from a distance without commuting.
  2. Enhanced productivity – Since there‘s no need to commute or pay for costly flight tickets and allowances to travel to sites, a lot of things can be done from any corner of the world where there is an internet connection.
  3. Convenience and flexibility - Employees and private individuals can work anywhere saving precious time and money.

How to set up a VPN

Depending on the type of VPN, businesses and organisations usually secure hardware which normally integrates with existing systems such as a firewall for data encryption and security. Private individuals can also set-up their own VPN connection by installing VPN software. Requirements vary since there are programmes that run on specific OS such as Windows, XP, and Vista.

Examples of VPN software are TeamViewer and FreeVPN. Both are available as free downloads for non-commercial users. You can control another computer, download files, and even conduct meetings remotely. They are handy to use reducing phone and fuel costs when family and friends need help with computing problems.

Safety in the long run

Knowing what is VPN and what it can do for your security while on the web is vital in ensuring data and identity protection for private or business concerns. It is a safe and convenient means of connecting people and sharing data to improve productivity. The only question is, how long can VPN technology stay ahead of the game before malicious threats compromise its safety?
