What Trend Micro is
Trend Micro's Site Safety Center rates URLs Safe, Dangerous, Suspicious or Untested for its consumer and business products. Re-classification is requested through the same portal.
What a Trend Micro flag looks like
A Trend Micro 'Website blocked' page or a red rating in the Trend Micro Toolbar.
Why clean sites end up flagged here
- A past compromise — an injected redirect, spam pages, a phishing directory — that the engine recorded and has not re-scanned since the cleanup.
- A file hosted on the site (an installer, an archive) that matched a signature, which flags the URL that served it.
- A verdict copied from another engine's feed, so the flag appears here days after the original source.
- A genuinely clean page that the engine's heuristics read as suspicious: obfuscated JavaScript, a login form, a redirect chain.
How a removal request reaches Trend Micro
This vendor takes website reports only through its own web form, usually with a CAPTCHA and sometimes an account, so a person has to submit it. The form is the only path into its review queue.
The exact portal, the fields it asks for, a template and the reasons requests get rejected are in the Trend Micro false-positive guide.
What unflagdomain does for this vendor
When a scan shows this vendor flagging your domain, your dashboard gets a prepared card for it: the vendor's form, the exact URL, and the text to paste. You submit it; the vendor replies to you.
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.
Trend Micro is an antivirus URL-reputation system: its verdict on a domain reaches everyone who runs that product, and it surfaces through multi-engine scanners such as VirusTotal, where other products and firewalls read it. A past compromise — an injected redirect, spam pages, a phishing directory — that the engine recorded and has not re-scanned since the cleanup. A file hosted on the site (an installer, an archive) that matched a signature, which flags the URL that served it.
Clean the site first and verify it from outside. Then this vendor takes website reports only through its own web form, usually with a CAPTCHA and sometimes an account, so a person has to submit it.

No stated turnaround. Trend Micro's knowledge base says to wait for a response from its Web Reputation Services team after validating the request. Not measured per vendor yet. In our most recent measured dispatch, all 12 flagging vendors had cleared within 15 days.
