Virtual Private Network, or commonly abbreviated as VPN, is a technology that is increasingly being used widely.
With VPN, users can get an internet connection that is relatively more secure and protected from snooping.
Various service providers are available now. Call it NordVPN, Surfshark, or Hotspot Shield. There are also some VPN services that can be used free of charge.

Free versus paid VPN
Free service is certainly more convenient in the pocket, but usually, the performance is also unreliable.
The cybersecurity observer explains that free VPNs do not provide adequate security guarantees.
They can retrieve data that is transmitted while the device is connected. Such as username, password, financial data, and others.
That means, there is a significant risk of data leakage. The device is also potentially infiltrated by spyware, malware, and adware.

That is why, experts advise users not to carry out transaction activities using free VPN, especially internet banking.
We never know if there is data or information that is taken and misused. For example, as happened in the case of Facebook Research.
This unrest is a question mark for prospective VPN users. Actually, how does a VPN work so that it can provide privacy and security?
Then what are the things to consider when choosing a service provider?

Understand how VPN works
VPN works by changing the user’s connection path through the server of the service provider while hiding the data exchange that occurs.
It’s easy, using a VPN is like accessing the internet with a special secret passageway.
To perform this function, network protocol support is needed. Some commonly used protocols are:
• L2TP / IPSec
• OpenVPN
• IKEv2 / IPSec
Various specific details such as speed, security, to the effectiveness of a VPN connection are determined by the type of protocol as well as the configuration used.
The most common protocol used is PPTP (point-to-point tunneling). This protocol does not require complicated installation and supports almost all operating systems, both desktop, and mobile devices.
