3 main benefits of using CyberSec

CyberSec feature protects from phishing websites

Block dangerous websites

The main task of the CyberSec feature is to protect you from phishing scams and other cyber threats. That's why it compares the address of every website you're about to visit against a vast database of blacklists. If you try to enter a site that is known for hosting malware, spyware, or other malicious software, CyberSec reacts immediately and blocks your access.

CyberSec protection against DDoS attacks

Avoid botnet control

With CyberSec protection on, your device will be safe from participating in DDoS (distributed denial-of-service) attacks. That applies even if malware has already infected it. CyberSec will detect and cut any communication between the device and the ‘Command and Control’ server of the botnet. This way, it will prevent your computer or any other gadget from joining a botnet zombie army.

Ads and unwanted pop-ups blocking VPN through CyberSec feature

Skip annoying ads

CyberSec hides unwanted pop-ups, autoplay video ads, and other advertising material the moment you enter a website. Not only does that allow you to enjoy the content you are there for, but it also improves the load speed of the site and saves you some precious mobile data. So finally, you can experience the internet ad-free, the way you have always wanted it to be.

How does CyberSec work?

Let’s start with the basics. When you wish to access a specific website (for example, NordVPN), you type its name into your browser ( Press “Enter” and that’s it – you’re in.

And that’s how your journey looks behind the scenes: The moment you enter the website’s name into your browser, your device contacts a remote DNS server to request the IP address of that particular site. Only when the Domain Name System (DNS) responds, you are actually directed to the website.

CyberSec feature explanatory scheme

1. User request to website
2. DNS server
3. Access allowed
4. Warning about detected threats

Now here is where the NordVPN CyberSec feature comes into play. It checks a real-time block list of websites that are known for hosting malware, spyware, trackers, or other harmful software. So when our DNS server receives your request to enter a specific site, CyberSec quickly checks its address against the list of possible threats and decides whether to allow the access.

If CyberSec blocks the website, you will see a warning message and will not be able to enter the site or see any of its contents. However, if for any reason you wish to proceed, you can do it at your own risk. To do that, disable CyberSec in Settings of the NordVPN app.
