How do our free online security tools work?

What is my IP?

Your public IP address tells any server you connect to where you’re coming from. Unfortunately, your virtual location can be used to track you, attack you, restrict access to censored websites, or even lock you out of your content (for example, your favorite streaming services may be unavailable while you’re traveling abroad.)

Many people shield their real IP address with VPNs or proxies for protection. Our “What is my IP?” tool lets you check whether your chosen cybersecurity measures are working and what others can tell from your current IP address.

IP address lookup

An IP address tells you a lot about a server or person. In addition to their internet service provider (ISP) and hostname, it also reveals their presumed location in the real world, down to the street that they’re in. This information can be very useful in the right circumstances — for example, messages from IP addresses in faraway places can expose disguised scammers.

NordVPN’s IP address lookup tool lets you easily check all publicly available information about a known IP address. Use it as the first step in verifying whether the person or website really are what they claim to be.

DNS leak test

Every time your device needs to connect to a website or service online, it must query a Domain Name System (DNS) server for its IP address. These queries reveal your every step to the DNS server operator (typically your ISP), so many people protect their privacy by using a reliable VPN with its own DNS servers.

Unfortunately, some VPNs suffer from DNS leaks — security flaws that result in some DNS queries going to your ISP’s servers. With our free online DNS leak test, you can check if your online activities are shielded from prying eyes.

Strong Password Generator_Alt

Password generator

Your password is your first and often only line of defense against cyberattacks. The difference between weak and strong passwords is like night and day — it only takes seconds for hackers to break into accounts protected by common words or phrases, whereas a good password can keep out even supercomputers for decades.

Using a sophisticated algorithm, the NordPass free online password generator will create impenetrable passwords for your accounts. Simply choose your desired password parameters and copy the result — that’s it! For even more convenience in your digital life, get NordPass to remember and auto-fill passwords for you.

Link Checker

Every time you click on a link, you’re taking a risk — at least a little bit. You never know what’s hiding behind a URL. It could be a legitimate link your coworker sent you or a phishing attack meant to steal your login credentials.

What should you do? Second-guessing your every move online is not a good way to live your life. So use our free tool instead — Link Checker will analyze the URL you’re unsure about and tell you if it contains malware or is known for scams, phishing, or other attacks. It uses a real-time list of websites that are known to be dangerous and NordVPN’s proprietary machine learning model to recognize zero-day phishing attacks.

File Checker

Malware can hide anywhere, even in legit-sounding files downloaded off of official-looking websites. You can’t just open the file to check — once you run it, the latent malicious code will immediately get to work infecting your device. Worse yet, in most cases, you won’t even know about the malware until after the damage has been done.

Don’t live in perpetual fear of the unknown. NordVPN’s File Checker lets you easily see what the file is hiding — by comparing the hash of your file against our robust live database of known malware signatures, our free tool can root out common viruses, trojans, and ransomware strains. Simply upload the file, scan it, and get on with your digital life.
