VPNs offer the best protection available when it comes to your online security. Therefore, you should leave your VPN turned on at all times to protect yourself from data leaks and cyber attacks. VPNs encrypt all the data that travels across your network, making it virtually impossible for hackers, ISPs and governments to see your personal information. Most of the time, yes, you should use your VPN, but not always.
It depends on the reasons you're using a VPN in the first place. If you're only using a VPN while streaming your favorite TV shows, it makes sense to turn it on or off for those purposes (for example, turning it off when you want a faster Internet connection). With good quality VPNs, the loss in speed is minimal, to the point where you won't even notice it. For example, Hotspot Shield offers a speed loss of only 0.41%.
Our research has shown that VPNs increase data usage by between 4% and 20%, depending on the VPN protocol you use. Similarly, some governments have started to ban known IP addresses that are associated with VPN providers. However, if your VPN's bandwidth is limited, you can try to continue watching it after turning it off. Because of this, VPNs have gained popularity in recent years, particularly in countries like China, where online censorship is rampant and sometimes dangerous.
However, while secure VPN companies make money on their subscription payments, a lot of free VPNs aren't. For example, while VPNs can cause slower connections, your connection speed may increase after you connect to a VPN provider. In the event that your connection to the VPN server is interrupted, you will suddenly be left without the protection and anonymity offered by your VPN. These clean addresses aren't associated with VPNs, giving you a better chance of avoiding attempts to block your access.
While many people use VPNs to stream online content, many (if not most) of the streaming services are very good at blocking the use of VPNs. In addition, many free VPN apps are not secure, since they have spyware or malware hidden in the download file. Understanding the disadvantages of using a VPN and appreciating what you can and can't do is a crucial part of staying safe online. Below, you can read about the disadvantages of a VPN, as well as the surprising difference between free and paid VPNs.
As such, a VPN connection is anything but a license to engage in derogatory, illegal, or reckless conduct on the Internet. For many of these companies, the sole purpose of operating a VPN service is to collect data to sell for profit.
