How do NordVPN's free network security tools work?

NordVPN has developed each network security tool with simplicity in mind. Some, such as My IP, use basic internet protocols to display your current IP address, while others offer more advanced functionality. For example, a seemingly simple file checker lets you quickly scan a file for signs of malicious activity. But under the hood, such tools use powerful and extensive threat intelligence to identify threats with speed and accuracy.

Sometimes, connecting a new device to your network, you may need to enter your IP address. If you don’t know it, an IP tool can tell you what it is. IP tools are also the easiest way to check if your VPN works properly — your IP address should change after you connect to a VPN server.

Everyday situations that call for network security tools

If you ever find yourself in one of these situations, here’s how you can solve them with free network security tools.

What’s my IP address before I connect to a VPN?

How do I know if my VPN is hiding my real IP address?

If you know your real IP address, you can turn on your VPN and check if the IP address has changed. You can also run a DNS leak test to see if your VPN is working.

How do I know if a website is secure before entering my information?

If you’re visiting a website for the first time and aren’t quite sure if it’s legit, use this free link checker. It will scan its databases of malicious websites and tell you if the website is secure.

What tools help protect against phishing attacks?
