How Safe is a Virtual Private Network (VPN)?

Virtual private networks are always associated with online privacy and online security as they are one of the safest and legal ways to protect your identity online. However, the basic rule of network security is to never let your guard down. Even if you have the best system protecting you, it is only a matter of time before it is compromised. Leading network security companies have time and again stressed for the need of regular updates for this reason only. They also never claim that the systems they are protecting are completely secure, which is absolutely true.

So, how safe are your VPNs? Is the channel through which you are communicating completely secured? Is the data flowing to the destination site passing though several ghost servers, where it can be accessed? This article will clear out all these doubts.

The Basics of VPN

The logic behind a VPN is pretty straightforward and simple, but the implementation is a very complex process. Firstly, the VPN is, as the name suggests, is virtually your own private network. Since it uses the existing network hardwares, a private pathway is created between your system and the destination, which is the URL you have keyed in the address bar. Since all the data flowing to and  from your computer will be within the private channel, others will not have access to it. This is different from where you don’t use VPNs where the data will be flowing through a common channel and all you need is a tuned receiver to receive it.

To further protect your data, it is encrypted before it is transmitted. It can only be decrypted at the receiver end. Even in the case your private channel fails, the encrypted data will make the job of a hacker harder.

Is the Channel Safe?

One of the major concerns of people using VPN is  if the channel they are using is safe or not. If you are using one of the top VPN service providers, rest assured that your data is safe. They use state of the art algorithms to make sure that the channels are properly shielded and nobody can gain access to the channels. Even the encryption algorithms are designed in such a way that no one can crack the code and get to the real data hidden in the seemingly random flow.

Can The Service Providers Access the Data?

Another question that people constantly ask is if their data is safe from the VPN service providers themselves. The answer to this query is that it absolutely is safe. The algorithms which are used to create the channels and encrypt the data make use of random number generators which will generate the code for encryption. Since the service providers do not have any measure of control over the random number generator algorithm, they have no way of decrypting the data or the channel through which your data will pass.

How Can VPN Hide Your Identity Online?

When you are using VPN, the IP address which you will be associated with will be generated by the VPN server. This will ensure that your IP address will not be visible to the destination site and hence, your location will not be revealed. The IP address will be randomly generated in such a way that you will appear to be originating from a different country altogether. The advantages of this fake IP usage are many, the most noteworthy being that you can shop without being tracked and hide your real identity online.

The VPN servers are also fortified with other online shielding techniques which will block the hackers from accessing the location of the VPN server. So, even if you are using a local VPN service provider, your location will remain discreet.
