VPN (virtual private network) is no longer a connectivity measure use by big companies and educational institutions to allow it’s users to access their in-house data and resource. VPN is now use to secure our connection to the internet on a daily base. Here is what VPN is and why you should start using it.
What Is a VPN?
VPN allows you to connect to the internet via a server run by a VPN provider. All data traveling between your computer, phone or tablet, and the “VPN server” is securely encrypted. As a result of this setup, VPNs: vpns_for_beginners
- Provide privacy by hiding your internet activity from your ISP (and government).
- Allow you to evade censorship (by school, work, your ISP, or government).
- Allow you to “geo-spoof” your location in order to access services unfairly denied to you based on your geographical location (or when you are on holiday).
- Protect you against hackers when using a public WiFi hotspot.
Allow you to P2P download in safety.
How Does it Work?
Normally, when you connect to the internet, you first connect to your internet service provider, which then connects you to any websites (or other internet resources) that you wish to visit. All your internet traffic passes through your ISP’s servers, and can be viewed by your ISP.
When using a VPN you connect to a server run by your VPN provider (a “VPN server”) via an encrypted connection (sometimes referred to as a “VPN tunnel”). This means that all data traveling between your computer / tablet / phone and the VPN server is encrypted so that only you and the VPN server can “see” it.
Your ISP cannot know what you do on the internet.
- It cannot see your data because it is encrypted
- It cannot know which websites (and so forth) you visit because all internet activity is routed through the VPN server.
- Your ISP can only see that you are connected to the VPN server.
You appear to access the internet from the IP address of the VPN server.
- If the VPN server is located in a different country to you, then as far as the internet is concerned you are located in that country too (most VPN services run servers located in many different countries).
- Anyone monitoring your internet activity will only be able to trace it back to the VPN server, so unless the VPN provider hands over your details your real IP address is hidden.
- This means that websites and so forth cannot see your true IP address (just that of the server).
Use VPN to access restricted streaming content not available in your geographic location from providers such as Netflix, YouTube etc…
It is safe to use public WiFi hotspots
The number one reason for using a VPN connection in my opinion is when we use those free WiFi connections being offered at those coffee shops, hotels, malls etc…
Because the internet connection between your device and the VPN server is encrypted. Even if a hacker somehow manages to intercept your data, for example by tricking you into connecting to an “evil twin” hotspot or packet-sniffing your WiFi data, the data is safe because it is encrypted.
Your VPN provider can know what you have been up to on the internet.
You are therefore shifting trust away from your ISP (which has no interest in, or commitment to, protecting your privacy) to your VPN provider, who usually promises to protect your privacy. Look for one that do not log any of your activities.
