What is a malicious website blocker?

A malicious website blocker is a security feature that automatically detects dangerous sites containing threats like phishing scams or malicious software and prevents users from accessing them. It compares the website you’re trying to visit against a database of malicious websites and analyzes it to spot suspicious activity and content.

What are malicious websites?

Malicious websites are dangerous web pages that cybercriminals set up to take advantage of unsuspecting internet users, ranging from phishing URLs designed to steal credentials to malware-infected sites that automatically download viruses. Common malicious website types include:

Phishing sites

They trick users into giving personal information.

Malware sites

They spread malicious software to users.

Scam sites

They deceive users to steal their money.

Adware sites

They install unwanted adware on devices.

Exploit sites

They use software vulnerabilities to access devices.

Drive-by download sites

They install malware on devices automatically.

Pharming sites

They redirect to fake websites that steal personal data.

Spoofing sites

They mimic real websites to trick users and steal their information.

Botnet sites

They infect devices and connect them to malicious networks.

Why block malicious websites?

Blocking malicious websites stops cyber threats before they ever touch your device. From stealing personal data to spreading malware, dangerous sites often disguise themselves as legitimate ones, making them easy to overlook even when you’re being careful. A malicious website blocker acts as your first line of defense, filtering out hidden threats automatically.

How does NordVPN’s malicious website blocker work?

Our malicious website blocker uses machine learning technology for real-time protection, blocking digital threats and making you safer online. It does so with the help of a transparent proxy, which filters out unwanted and harmful content.

When scam, phishing, and malware protection is on, your internet traffic goes to the transparent proxy first before accessing a site. The proxy acts as a digital guardian, checking if the website you’re about to visit is dangerous. If it is, we block the website and show you a warning message instead. You can still choose to visit this website, but we wouldn’t recommend doing so.

A browser warning marks a website as unsafe because it contains security threats.
