Can VPNs Keep You Safe Online?
Whenever you read online articles about online security, you almost always see VPNs mentioned there. Are they really that good?
Well, VPNs are excellent security tools, but they have their limits. everything you need to know., so you should be safe using them. Still, if you want to learn how exactly a VPN can keep you safe on the web (and when it can’t), we’ve got your back – this guide will explain
How a VPN Keeps You Safe Online
Let’s take a quick but in-depth look at the different ways VPNs protect your data when you’re on the Internet:
It Hides Your IP Address
One of the main ways VPNs protect your data is by hiding. That means the VPN stops anyone (sites, government surveillance agencies, torrent users, hackers, etc.) from seeing your real IP address.
What do they see instead?
The VPN’s IP. Think of the VPN as a secret agent that takes a bullet for you. Except that bullet is hackers and websites trying to snoop on and collect your IP.
VPNs hide your IP by sending your traffic through one of their servers. Due to that, any site you connect to will think the VPN is sending requests, not your device. Your connection will pretty much look like this:
Your Device VPN Server Websites
Without seeing your IP, websites, advertisers, and hackers won’t know what country you’re from. They won’t be able toyour access to content, and they won’t be able to track your online movements and associate your preferences with your IP.
It Encrypts Your Traffic
When a VPN routes your traffic through one of its servers, it encrypts it. That means it transforms your data from a readable format to an unreadable format. Translated, that means that nobody will be able to see your traffic – not even your ISP!
Sure, they can try to spy on it, but they won’t see anything relevant. Instead of seeing where your connection requests are heading, they’ll only see gibberish.
By encrypting your traffic, VPNs also offer protection against tip you off that something’s not right.(when hackers try to redirect your connections to fake sites). Cybercriminals can still target you with them, but they up in since they can’t see your traffic. You’ll become very suspicious when you end up on a fake version of your bank’s site when you were supposed to end up on Facebook. That’s enough to
It (Maybe) Blocks Ads & Malicious Sites
We say “maybe” because not all VPNs have ad-blocking features. The ones that have them keep you safe from annoying ads. They stop them so you won’t see them on social media and media outlets. Unfortunately, you’ll still see them on YouTube (to get rid of them, please use ).
On top of blocking ads, VPN ad blockers can also block traffic to and from malware-infected sites. VPN providers use blocklists to blocklist IPs and domains affiliated with scammers, malware, phishing, and more. When you accidentally connect to such a site, the VPN will act as a firewall and not let your connection go through.
So bottom line – VPN ad blockers can keep you safe from MITM attacks and phishing attacks.
When VPNs Can’t Keep You Safe Online
There are also situations when a VPN can’t protect your online data. It doesn’t happen often, but there are still a few scenarios you need to be aware of:
When It Suffers Leaks
VPNs that are not configured right can suffer data leaks. That mostly means they fail to encrypt all your data (like your IP address). Here’s what kinds of leaks VPNs can suffer:
- IPv6 leaks – If the VPN doesn’t support or block IPv6 traffic, your IPv6 address will be revealed when you use the VPN to surf websites that use IPv6 traffic.
- DNS leaks – If a VPN doesn’t run its own encrypted DNS servers, it can suffer DNS leaks. That means your DNS traffic leaks outside the VPN tunnel because you use your ISP’s DNS servers (they can see what sites you browse).
- WebRTC leaks – WebRTC leaks can expose your IP address to various sites. If VPNs don’t have built-in WebRTC leak protection, you’ll need to use uBlock Origin.
- Traffic leaks occur when your VPN connection drops (your data is exposed until the VPN reconnects). VPNs prevent traffic leaks by offering kill switches ( until the VPN reconnects).
Most VPNs don’t have WebRTC leak protection, but top VPNs will protect you against all other leaks. If they don’t offer any leak protection, they won’t be able to keep you safe online, though.
When It Keeps Logs
If a VPN keeps logs, it monitors your data while you’re connected to its servers. It could log your IP address, the sites you visit, and the files you download.
When You’re Dealing with Malware Infections
If you download and run a malware-infected file to your device, a VPN can’t prevent it from getting infected.
VPNs just aren’t designed to work that way. The best they can do is block connections to malware-infected sites. But there’s no way for them to protect your hardware from viruses.
That’s why you should always use an antivirus program and a VPN.
