ZeroFox flagged my website — how removal works
CATALOG ENTRY VERIFIED 2026-09-21
ZeroFox 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. It accepts website false-positive reports by email request. unflagdomain sends that request for you as part of a €39 dispatch; ZeroFox reviews the site itself and decides on its own schedule.

What ZeroFox is
ZeroFox provides digital-risk and phishing intelligence; its URL verdicts appear on VirusTotal and in products that consume its feeds.
What a ZeroFox flag looks like
Visitors on a network or device that consumes this feed cannot reach the site, or see a block page naming the product that consumed it. On VirusTotal and free checkers, a line under this vendor's name.
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 ZeroFox
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 general procedure — clean, verify from outside, one specific request, wait for the re-check — is in the complete removal guide, with the checklist of what every request must contain.
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.
