Hello All,

HI @IceIronDragon ,
I trust you are doing great.

Here's how you can achieve it:

1. Access the ServiceNow instance as a user with administrative privileges.
2. Navigate to the "Configuration Management" module in ServiceNow.
3. Go to the "Identification and Reconciliation" section.
4. Create a new IRE rule by following these steps: a. Click on "New Rule" to start creating a rule. b. Give the rule a meaningful name and description. c. Specify the appropriate conditions to identify duplicate CIs based on the data received from the Qualys integration with VR. You can use attributes like name, IP address, or any other unique identifier to determine duplication. d. Define the reconciliation strategy, which can involve merging duplicate CIs or updating existing CIs with the most recent data. e. Save the rule.

Once the IRE rule is created, ServiceNow will automatically run it on incoming CI data from the Qualys integration. The identified duplicates will be reconciled based on the defined strategy.
