An Insider's View About VPNs -- Dangerous or Private?
Introduction
VPNs are an essential tool for privacy, but they're also a minefield. You may have run into issues with some VPNs or have questions about which is best for your needs. In this article, I'll answer common questions and explain how people can protect themselves from bad VPNs.
Most people think of a VPN as a way to protect their online activities, which it is.
The most common reason for using a VPN is to protect your privacy. This has become more important in recent years as governments and corporations have begun to collect massive amounts of data about us, much of which we don't want them to have.
VPNs also help keep hackers out of your computer or phone by encrypting all traffic passing through the network so that it can only be read by people with access credentials (you). This means that even if someone could hack into your device, they wouldn't be able to see what was happening inside it because everything would appear gibberish!
Another important VPN use is protecting yourself from government surveillance programs like PRISM and Tempora (in the UK). These programs allow government agencies like the NSA or GCHQ access to servers run by Google/Facebook/Twitter, allowing them to see whom you talk with online without having any legal authority!
The most secure VPN is one that you own and control.

You can't trust other people to protect your data, and even if they do, they may be unable to keep it safe forever. For example, a hacker group could take over the server hosting your VPN provider's website and then change all of its settings--and there would be nothing you could do about it!
Also, consider how much information about yourself (and potentially others) is being sent back to companies when using public or paid VPNs: this includes everything from payment details to location data that advertisers or law enforcement agencies could use. Free or inexpensive VPNs likely make you and your personal information the product; if so, why bother with a free or cheap service?
But many people are unaware that they must protect themselves from the VPN.
But many people are unaware that they must protect themselves from the VPN. A VPN is a service that allows you to connect to an encrypted network through which all of your traffic travels. This can be used for good (for example, if you're trying to access content blocked in your country) or bad (if a government wants to spy on its citizens).
Users need to know what sort of risks they face when using a VPN because there are ways in which these services can be hacked or used against them. For example, hackers could intercept data sent over the network and use it against users; similarly, governments may try to monitor their citizens' activities by using their versions of these networks called "man-in-the-middle attacks."
Building and using your VPN server is not complex.
If you're looking to build your VPN server, there's no need to be intimidated by the process. It's pretty straightforward--you need to know how to set up a VPN server.

Suppose you're using Linux as your operating system of choice (and why wouldn't you?). In that case, there are plenty of ways to do this: whether it's through installing OpenVPN on Ubuntu or CentOS, creating an OpenVPN bridge in Debian/Ubuntu/CentOS/Fedora/ArchLinux with NetworkManager, or setting up an L2TP/IPsec server with NetworkManager for Fedora 22+. Alternatively, if none of those options sound appealing because they require manual configuration steps each time they're used (or because they only support one protocol), then consider using DigitalOcean Cloud Servers instead; these come pre-installed with everything needed for setting up both PPTP and L2TP connections automatically--no fuss required!
In any case, however...
This is why it's essential to read reviews and ensure you're using a trusted VPN service.
It would help to use a VPN that doesn't log your data.

The most important thing about a VPN is its encryption.
The most important thing about a VPN is its encryption. The more secure the encryption, the faster your data will be. A trusted VPN will use AES 256-bit encryption or something similar--the same type of encryption used by banks and other large organizations to protect their sensitive information from hackers.
What does this mean for you? First, it means that when using a good VPN, no one should be able to see what websites you visit or what files are being transferred (unless they have physical access to your computer).
A trusted VPN will use OpenVPN with AES 256-bit encryption or something similar.
A good VPN will use OpenVPN with AES 256-bit encryption or something similar. This is the best encryption method available today, and most reputable VPN providers use it.
OpenVPN is an open-source software package that allows you to create a secure connection between your computer and another computer on the internet (or vice versa). It creates an encrypted tunnel between two points on either side of the bond--your computer, for example, and one at your VPN provider's server farm in Iceland or wherever they might be located.
Conclusion
The most important thing about a VPN is its encryption. You can learn more about the different types of encryption by reading our guide on the topic but in short. If you use a VPN, make sure it uses OpenVPN with AES 256-bit encryption or something similar.
