Below are the six reasons why I think a VPN is worth getting:
1. Protecting Your Online Privacy
First and foremost, VPNs are internet privacy tools. Even if you use HTTPS websites, your ISP can still see which websites you visit.
By encrypting your traffic and and tunneling it through a remote server, a VPN hides your online activity from snoopers like your ISP, which can no longer see what you’re doing on the internet.
A VPN also hides your IP address from every website you visit, which makes it much harder for advertisers to track, profile, and target based on your location. It won’t stop every kind of tracking though – more on that below.

2. Accessing Geo-Restricted Web Content
Another popular use of VPNs is to access region-locked entertainment around the world.
By changing your IP address, a VPN can make it appear as if you’re located in a different region or country, unblocking streaming content that you wouldn’t normally be able to access.
For instance, if you’re subscribed to Netflix, a good VPN will allow you to change your Netflix region and access titles only available in other countries’ content libraries.

NordVPN unblocked US Netflix every time I tested it, along with several other regions.
I’ve used VPNs to access 120 streaming services around the world, but not all VPNs are good at this.
Streaming services like Netflix and BBC iPlayer actively try to block VPN traffic, and in my testing, only the best VPNs for streaming can get past these restrictions with consistently.
3. Unblocking Websites in Highly Censored Countries
VPNs are essential if you live in a country with high levels of online censorship, since they will allow you to bypass the country’s strict firewalls, and access blocked websites and apps.
If you’re traveling or moving to countries like Turkey, Russia, or China, I strongly recommend you use a VPN with obfuscation technology to keep access to your usual internet services. Without it, I’ve watched otherwise excellent VPNs fail to connect at all.

4. Getting Cheaper Deals and Subscriptions
VPNs make it look like you’re in another region, so you can sometimes pay for services at local prices.
For example, you can use a VPN to get a Ukrainian or Brazilian IP address and get a cheap Netflix account.
I’ve also used VPNs to stream live sports for substantially less.
5. Securing Public WiFi Networks
Using public WiFi is a lot safer than it used to be, now that almost every site is encrypted with HTTPS. However, there are still risks from hackers and malicious actors on the same network, and that the WiFi owner can see your internet activity.
A VPN for public WiFi allows you to connect securely to free WiFi networks , hiding your activity from the network owner and stopping third parties from injecting malicious content into your traffic.
Although the risks today have shrunk, it’s still worth using a VPN for peace of mind when using public WiFi, especially if you’re doing something sensitive like online banking.

I always use a VPN to connect to public WiFi.
6. Hiding Your Torrenting Activity
If you torrent without a VPN, your IP address is visible to other peers in the swarm, and the files you download are visible to your ISP.
Accidentally downloading copyrighted material would put you at risk of legal penalties pursued by copyright trolls, licensing companies, or your ISP itself.
By using a secure VPN that doesn’t log what you do online, you can stop your internet activities from being traced back to you. And if there was a legal request for information about you, there wouldn’t be any records to hand over.
