Based on the input observables, the enricher searches the source Cisco Umbrella DNS database for matches.

Retrieved matches are stored in the platform as enrichment observables related to the corresponding input IP addresses.
They are not automatically assigned a maliciousness confidence level because they may not necessarily be malicious.

The default Source reliability value for this enricher is C – Fairly reliable.
You can change it to a different reliability value, as needed.


Users need an API key. Log in to Cisco Umbrella, and then go to the Investigate API Access area to create a new API token.
