Updated Lookup

 

SecOpsDomesticCountries

The DomesticCountries lookup adds more whitelisting functionality to your Devo Detections by allowing them to reference this lookup of expected countries within your domestic space, often used for impossible traveler-like use cases. Using this lookup will lower your false positive rate when properly configured and can help make your alerts more actionable!
