When you want to add external information to Active Lists in ArcSight as a solution, you have to build a custom flex connector, parse the data, and create a pre-persistent rule that will add the information to the Active List.
The CyberSIEM team has developed a tool that makes taking care of these exclusions as simple as creating an Active List.
Any conversation with the bot has a unique Chat ID, the bot will need this ID to know where to send the message. Of course, you can use the same bot for a few conversations, and send different alerts to each group.
We, CyberSIEM, developed a tool that will delete the cases with the ArcSight API the right way, without hurting the job.
