Hello, yes we do have an internal bundle that handles Cisco ASA NSEL. It hasn't been formally published yet to the external Bundles Gallery, but we plan to do so hopefully within the next few weeks.
We are beta testing this in a couple of customer environments now. I've attached the bundle here if you'd like to try it out. Today, the aim of the bundle is to export ASA NSEL records to EXA...hence you need to have the ExtraHop eXplore Appliance (EXA) for this.
Please funnel any Q&A or feedback through your regional ExtraHop Systems Engineer. Thanks very much!
