Can free VPN services attain my credit card information passwords and emails while being used?

VPNis the acronym of Virtual Private Network. Thanks to the VPN, you can connect remotely to a network where you are not physically present. Professionals use this technology to connect to their company's local network as if they were there. On the other hand, ordinary citizens often use VPN to enter banned sites.

How does VPN work?

VPN uses many different protocols and technologies. However, it basically opens an encrypted tunnel from the physical location of your computer to the opposite network. The information transmitted through this tunnel cannot be viewed outside because it is encrypted. Security experts can see encrypted data flow, but they can't understand what their content is (unless a very weak security is used). VPN programs install a network drive specific to your computer or mobile device. VPN systems sometimes come embedded in mobile devices. At this point, it acts as a virtual network adapter, giving you an IP number from the opposite network. This allows you to access allowed applications or local addresses.

The Price of VPN 

Many foreign-based companies on the market offer general or customized VPN solutions. Prices of these services are changing around $ 10-20  per month. For non-paid services, there is usually a limit on the amount of data, and after a point, it either stops completely or slows down so you don't want to use it. Companies that provide the VPN services free of charge have a purpose. In fact, in any case, you pay a price. 

Is VPN secure?

A research on 283 different VPN applications conducted by Data61 / CSIRO, UC Berkeley, UNSW Sydney, and UCSI, revealed that most of the VPN applications were found to contain adware, trojans, malvertising or spyware. The most notable details of the findings include:

18 percent of VPN services don't encrypt traffic, 84 percent of the user data is leaking, 38 percent make you expose to bugs or malicious ads, and 80 percent want access to user accounts or text messages.

Research shows that especially free VPN services offer much more risk than they seem to be. These risks include stealing your personal information, critical information such as your credit card and merchant account. In fact, if you see 'free' you should be concerned when it comes to VPN apps and services. Unknown application developers can use users as the endpoint to support other customers or for extra bandwidth. In fact, providing VPN service is quite expensive. If someone gives you this service free, someone else is likely to use your connection. 

The most serious risk for free VPN applications is that you lose control of your data. A VPN service must encrypt your data flowing from your device to servers. At this point, your data goes into the open Internet. However, poor quality or poorly configured services can cause your traffic to be intentionally or accidentally compromised. Thus, your critical information such as credit card information, passwords, and e-mails can be attained.
