Indicator Verdict
Indicator verdict affects how the indicator is processed
and handled in Cortex XSOAR. Assigned by reputation returned by
the source with highest reliability.
An indicator’s verdict is assigned according
to the verdict returned by the source with the highest reliability.
In cases where multiple sources with the same reliability score
return a different verdict for the indicator, the worst verdict
is taken.
Indicator verdicts
Indicators are assigned a verdict on a scale of 0 to 3.
Score | Verdict | Color |
|---|---|---|
0 | Unknown | Gray |
1 | Benign | Green |
2 | Suspicious | Orange |
3 | Malicious | Red |
You can change the benign verdict by editing the indicator.
If you have manually changed the indicator’s verdict and want to
recalculate it according to enrichment integrations, click

when
editing the indicator.Source reliability
The reliability of an intelligence-data source influences the
verdict of an indicator and the values for indicator fields when
merging indicators.
Indicator fields are merged according to the source reliability
hierarchy. This means that when there are two different values for
a single indicator field, the field will be populated with the value
provided by the source with the highest reliability score.
In rare cases, two sources with the same reliability score might
return different values for the same indicator field. In these cases,
the field is populated with the most recently provided source, unless
the field is verdict. If two sources have the same reliability score
and return different values for the verdict field, the worse verdict
is used.
For the field types Tags and Multi-select, all values are appended,
nothing is overridden.
Source | Reliability Score | Notes |
|---|---|---|
Manual | A+++ | A user manually updates the verdict of an indicator. |
Reputation script | A++ | A script with the reputation tag, which
calculates the verdict of an indicator. For example, the DataDomainReputation script
evaluates the verdict of a URL or domain. |
3rd-party enrichment | A+ | An integration or service that evaluates the
verdict of an indicator. For example, the urlscan.io integration
evaluates the verdict of a URL. |
Feed | A: Completely reliable | The feed reliability is applied at
the integration instance level. |
B: Usually reliable | ||
C: Fairly reliable | ||
D: Not usually reliable | ||
E: Unreliable | ||
F: Reliability cannot be judged |
Example 1
In this example, two 3rd-party integrations, VirusTotal and AlienVault,
return a different verdict for the same indicator. The indicator’s
verdict will be Malicious because VirusTotal’s reliability score
is higher than AlienVault.
Integration | Reliability | Verdict | Final Verdict |
|---|---|---|---|
VirusTotal | C - Fairly reliable | Malicious | Malicious |
AlienVault | D- Not usually reliable | Benign |
Example 2
In this example, two sources with the same verdict score return
a different verdict for the same indicator. The indicator’s verdict
will be Malicious because when two sources have the same reliability,
the worse verdict applies.
Integration | Reliability | Verdict | Final Verdict |
|---|---|---|---|
TAXII Feed | B - Usually reliable | Malicious | Malicious |
CSV Feed | B - Usually reliable | Benign |
