Threat Intelligence

Block Lists

Browsers and Antivirus software maintain massive databases of dangerous websites. If you end up on one, visitors will see a scary red warning screen instead of your content.

Check Block Status

Scan Google Safe Browsing & PhishTank

01 The Internet's "Most Wanted"

Unlike spam lists that just block email, Block Lists are used by Chrome, Safari, and Firefox to physically prevent users from loading your website. They are designed to stop users from accidentally downloading viruses or giving passwords to fake sites.

02 The "Quarantine" Analogy

Being on a Block List is like having your store wrapped in "DO NOT ENTER" tape by the health department:

The Warning
Customers try to open the door, but a guard (the Browser) stops them saying "It's unsafe inside."

The Cause
Usually caused by a hidden infestation (malware) that you might not even know exists.

03 The Big Keepers

We check against the most influential safety databases:

Google

Safe Browsing

Used by Chrome, Safari, and Firefox. The single most important list on the web. Blocks billions of URLs per day.

PhishTank

Community Driven

A collaborative database of phishing sites (fake login pages), often used by enterprise security filters.

Antivirus

Vendors

Lists maintained by companies like McAfee, Norton, and ESET to protect their desktop users.

04 The Consequence

If you get flagged, traffic drops to near zero instantly.

Trust Destroyer: Even if you fix the issue later, users who saw the "This site is dangerous" warning may never trust your brand again.

05 Getting Clean

1. Scan & Clean

You MUST find the malware or phishing page first. Check your /wp-content/uploads folder and obscure PHP files.

2. Verify Identity

Add your site to Google Search Console to see the official security report.

3. Request Review

Once you are 100% sure it's clean, use the "Request Review" button in Search Console. Google will re-scan your site.

Prevention is better: Regular scans with our homepage tool can alert you to a block listing before it impacts all your users.

06 Frequently Asked Questions

What is the 'Deceptive Site Ahead' warning?

This is a full-screen red warning from Google Chrome (powered by Safe Browsing API) that blocks users from entering your site because it detected phishing or malware.

How did I get blocked?

Common reasons include: a hacked CMS (WordPress plugin), hosting a phishing login page (even unknowingly), or having downloads that antivirus software flags as dangerous.

Is this different from an Email Blacklist?

Yes. Email blacklists stop your *emails*. Block lists stop *visitors* from viewing your website in their browser.

How long does review take?

Google Safe Browsing reviews usually take up to 72 hours. PhishTank and others depends on community verification.

Stay Off the List

Ensure your site is welcomed by every browser.
