Frequently Asked Questions

What does this website do?

Total Security Check scans your network, browser, and any website you enter to find security weaknesses and privacy risks. All scans run instantly in your browser and show you exactly what information is exposed online.

Why should I check my home network?

Your router and network can expose open ports, reveal your real IP address, or leak DNS requests without you knowing. Hackers use this information to target devices on your network. A quick scan shows what's visible from the outside.

What is a WebRTC leak?

WebRTC is a browser feature used for video calls and file sharing. Unfortunately, it can reveal your real IP address even when you're using a VPN. Our browser scan detects if your browser is leaking your IP through WebRTC.

What is browser fingerprinting?

Websites can identify you by combining details like your screen size, installed fonts, timezone, and browser plugins. This unique combination creates a "fingerprint" that tracks you without cookies. Our scan shows how unique and trackable your browser is.

What does the website security scan check?

We analyze SSL certificates, security headers, DNS configuration, and server settings. This reveals if a website properly encrypts data, protects against common attacks, and follows security best practices.

Is it legal to scan a website?

Yes — our scans are completely passive. We only check publicly available information that any browser would receive when visiting the site. No intrusive testing or vulnerability exploitation is performed.

What is a DNS leak?

When your DNS requests go through your ISP instead of your VPN, websites and your internet provider can see which sites you visit. Our scan detects which DNS servers handle your requests and whether they're exposing your browsing activity.

Do I need technical knowledge to use this?

No. Each scan explains results in plain language with clear recommendations. You'll understand what's safe, what's risky, and what you can do to improve your security — no IT background required.

Does this site store my scan data?

No. All scans run locally in your browser or are processed temporarily on our servers. We don't save IP addresses, scan results, or any personal information. Your privacy is the whole point.

How often should I run these scans?

Run a scan whenever you change your network setup, install a new browser or extension, update your VPN, or just want to verify everything is secure. Monthly checks are a good habit for staying protected.
