Sucuri flagged my website — how removal works

CATALOG ENTRY VERIFIED 2026-09-21

// ANSWER

When Sucuri SiteCheck says a site is blacklisted, read which list it names. SiteCheck also shows Google Safe Browsing, McAfee, ESET, PhishTank, Yandex and Opera, and each of those needs its own request. Only a Sucuri Labs listing is Sucuri's own. Report that one by email to Sucuri's Research / Labs address, which is listed on Sucuri's contact page, with the URL and evidence the site is clean.

What Sucuri is

Sucuri's SiteCheck scanner shows other vendors' blocklists alongside Sucuri Labs' own list, which appears on VirusTotal. A SiteCheck 'blacklisted' result must be read vendor by vendor before anything is reported to Sucuri.

What a Sucuri flag looks like

A 'Site is Blacklisted' banner on sitecheck.sucuri.net, and 'Sucuri SiteCheck' as an engine line on VirusTotal.

Why clean sites end up flagged here

  • A URL on the domain was seen distributing malware or hosting a phishing page, and the feed keeps the entry until its next crawl finds it gone.
  • A single automated sighting — one crawler, one sample — with no human review.
  • Shared infrastructure: the same IP, certificate or hosting neighbourhood as something that was flagged.
  • A new or parked domain with no history to rate.

How a removal request reaches Sucuri

This vendor accepts a website false-positive report by email at an address it publishes in its own documentation. The message must be plain text, come from an address at the affected domain or a contact the vendor can verify, and state the URL, what was found, what was removed and when.

The exact portal, the fields it asks for, a template and the reasons requests get rejected are in the Sucuri false-positive guide.

What unflagdomain does for this vendor

When a scan shows this vendor flagging your domain, a separately written plain-text request goes out to it in the dispatch, with your address as Reply-To, so the vendor's answer lands in your inbox. If the address bounces, another working contact is looked for and the request re-sent.

This is one of 133 vendors in the catalog. A scan shows which of them flag a domain right now; the €39 dispatch covers every one that does.

// SUCURI FAQ
  • Sucuri is a reputation or threat-intelligence feed consumed by firewalls, CDNs, DNS filters, mail gateways and security plugins. It rarely shows a browser warning itself; the block appears downstream, often on a company network. A URL on the domain was seen distributing malware or hosting a phishing page, and the feed keeps the entry until its next crawl finds it gone. A single automated sighting — one crawler, one sample — with no human review.

  • Clean the site first and verify it from outside. Then this vendor accepts a website false-positive report by email at an address it publishes in its own documentation. The message must be plain text, come from an address at the affected domain or a contact the vendor can verify, and state the URL, what was found, what was removed and when. The Sucuri guide on this site has the portal, the fields and a template.

  • No stated turnaround for Sucuri Labs blacklist reviews. Not measured per vendor yet. In our most recent measured dispatch, all 12 flagging vendors had cleared within 15 days.

  • When a scan shows this vendor flagging your domain, a separately written plain-text request goes out to it in the dispatch, with your address as Reply-To, so the vendor's answer lands in your inbox. If the address bounces, another working contact is looked for and the request re-sent. We guarantee the request is sent or prepared; Sucuri decides the outcome.
