CA Top Secret for VSE does not have any built in API that interfaces with CA Top Secret Auditing and logging.
You can run a TSSUTIL EXTRACT job to extract the audit records from the CA Top Secret Audit Tracking File and put it in a dataset.
At that point they can use QRadar to extract the info or build a database from it.
TSSUTIL is batch. There is no realtime.
If you were a z/OS customer, TSS for z/OS has a Compliance Event Manager which is exactly what you would need. It basically dumps security records into a database so you can run queries on it.
There is no z/VSE version and none planned in the future.
