While browsing the internet, you suddenly see a red page with a large warning triangle and the title "Security Warning". The page tells you that the website you were trying to visit has been flagged as potentially dangerous. This is the UnveilPass Phishing & Malware Protection in action. Here is what it means and what you should do.
This website has been flagged as potentially dangerous.
The UnveilPass browser extension checks every website you visit against multiple blocklists of known phishing sites, malware distribution points and scam domains. When a match is found, the extension blocks the page before it loads and shows you the Security Warning screen instead.
A website can be flagged for several reasons:
Phishing and malware sites are designed to look convincing. They often mimic the exact design of legitimate websites — the same logo, the same colors, the same layout. The only difference is the URL. Do not trust appearances.
If you believe you were trying to visit a legitimate website, take a moment to examine the domain name shown in the warning. Phishing sites use domain names that look similar to real ones but with subtle differences:
paypa1.com instead of paypal.com (number 1 instead of letter l)amaz0n-login.com instead of amazon.com (zero instead of o, extra words)secure-banking.mybank.fake-domain.com — the real domain is fake-domain.com, not mybankmicrosoft.com.login-verify.net — the real domain is login-verify.net, not microsoft.com/ in the URL. In https://login.secure.paypal.com/auth, the real domain is paypal.com. In https://paypal.com.evil-site.net/auth, the real domain is evil-site.net.Think about what led you to this website. This is often the most revealing clue:
If you need to access the service that the blocked site was impersonating, always type the official URL directly in your browser's address bar. Do not use the link that brought you to the blocked page.
www.mybank.com)www.amazon.com)www.facebook.com)If you have the legitimate site saved in your UnveilPass vault, use the extension to navigate there — it will take you to the correct URL every time.
The Security Warning page includes a second button: "I understand the risk". This button allows you to bypass the warning and proceed to the website anyway. It exists for rare cases where you are absolutely certain the website is safe (for example, a newly registered domain for your own project that has not been removed from blocklists yet).
If you bypass the warning:
If you believe a legitimate website was incorrectly blocked, you can report it to us. False positives can happen when a newly registered domain appears on a blocklist by mistake, or when a previously compromised domain has been cleaned up but not yet removed from all blocklists.
Contact us at support@unveiltech.com with the domain name and we will review it. We update our blocklists regularly and can add exceptions for confirmed legitimate domains.
Every blocked and bypassed domain is recorded in your UnveilPass console. Go to the Statistics page and scroll down to the Phishing & Malware Protection section. You will see a table of all domains that were blocked, how many times each was detected, and when they were last seen.
Phishing & Malware Protection is enabled by default for Pro users. You can toggle it in the extension popup under the Settings tab. We strongly recommend keeping it enabled at all times — it adds an essential layer of security with zero impact on browsing speed.
Phishing and malware protection is included in UnveilPass Pro. Block dangerous websites automatically while you browse.
Get Started FreeWhen you see a Security Warning, the right reflex is simple: go back to safety. Check the URL, think about how you got there, and navigate to the real website directly. Never enter your credentials on a site that triggered a warning. The few seconds it takes to verify a URL can save you from losing access to your accounts, your money, or your personal data.
