Analyst Q&A

What this signal answers

The questions every analyst asks before acting on this signal.

What it detects01

What does 'Not Listed in Open-Source Threat Feeds' mean?

It indicates that the domain does not appear in any public or open-source threat intelligence feeds, malware repositories, or IOC databases. This means no external OSINT provider has associated the domain with any known malicious campaigns or infrastructure.

Why it matters02

Does this confirm the domain is safe?

Not necessarily. It simply means the domain has not been reported as malicious by open-source intelligence sources. Newly registered domains or previously inactive domains might not yet be indexed in public feeds, so further contextual analysis is recommended.

How analysts use it03

How should analysts interpret this indicator?

It should be considered a neutral-to-positive signal. While the absence from OSINT feeds suggests the domain is not widely recognized as malicious, analysts should still validate this with internal telemetry, DNS behaviors, and proprietary threat intelligence data.
