A VPN (Virtual Private Network) enables a secure Internet connection. It is privacy-oriented cybersecurity software that masks users IP addresses and encrypts online traffic, and no one who intercepts the encrypted data can read it.
If your data is transmitted unencrypted, it can be viewed by anyone who has access to the network, for example, from your internet provider. A VPN creates a private “tunnel” between your device and the Internet, protecting your data using encryption.
The VPN server is an intermediary between your device and the target site. The target page answers the VPN server’s request and returns the data to the VPN server. There is no direct exchange of data between you and the target page.
Going online is like boarding an airliner. Security personnel, baggage handling, flight attendants and the flight counter require your data. Something similar happens on the Internet. Your data goes through different servers. If you’re surfing the web to pass the time, you might not have a problem with letting anyone see your unencrypted data. However, things are very different when it comes to business email, online banking, or other sensitive data. Without using a VPN, all of your online activity is traceable back to your physical location. With VPN access, you hide your IP address and create an additional level of security by encrypting your Internet connection.
Businesses often use VPNs to access the company network while on the move securely.
When you use public WiFi, your browsing activities on non-HTTPS websites are visible. If you want to hide your browsing activity, you should connect to a VPN, and the network then only sees a secure VPN connection.
With a VPN, you can access geo-restricted services. For example, to access your Netflix account while travelling abroad.
Many people use VPN access to bypass internet censorship.
To access your home network when you’re out and about, you can set up your VPN (Virtual Private Network). This allows you to access a remote Windows desktop, share local files, and play games over the Internet. As if you were at home on the LAN.
After installing the VPN software, you usually only have to enter your user name and password. Then select a server, and off you go. Most VPN providers also offer detailed instructions.
Depending on the provider, a VPN can slow down the internet speed. However, with most reputable VPN services, a braking effect is usually not noticeable.
The farther away the VPN server you are connected to is, the more significant the drop in speed.
