What you need to look for is your data being encrypted with the AES algorithm of at least bits. Your VPN can be super secure, but it all comes down to the connection protocol the encryption mechanism used to handle your information.

All good VPN companies will do everything they can to protect your data, your privacy, and your overall security on the web. Depending on the local law of the country where the VPN was established, the company may be forced by court order to share whatever records they have regarding your activity — and there can be international agreements between countries to share information in these cases.

But the extent to which it does is still impressive. Without a VPN, your connection is fully open, and your ISP, the cafe WiFi router, any server along the way, or a person with the right tools can look at your data.

Running a good VPN service costs serious money — robust servers, data transfer, infrastructure, employees, and so on. If the service is offered for free, consider what compromises may have been made.

Piracy, on the other hand, is completely illegal regardless of the tools that you use to do it.

The way Netflix and Hulu block some of their content in parts of the globe is based on location filters. VPNs make this easy to fix.

At this stage, you have the VPN connection and the Tor web browser running at the same time.

Tor on its own slows down your experience noticeably, and when combined with a VPN, the results can be even more dramatic. On the plus side, it gives you super privacy , which is a huge plus. A kill switch is a feature that automatically kills your internet access if the encrypted, safe connection should ever drop. IP leaks are a known vulnerability with some setups people use to access the web. For example, you want to access a geo-restricted show on Netflix, so you change the server to an approved country and reload the page. Then you realize that the content is still blocked.

This means that your real IP might have just been leaked. The vast majority of people these days are using VPN for torrenting or bypassing geographic restrictions to watch content in a different country. All your network traffic is sent over a secure connection to the VPN. When you browse the web while connected to a VPN, your computer contacts the website through the encrypted VPN connection.
