Hello @_mukesh, I would recommend getting in touch with your local GCP Representative to pursue a trial.

does google still use siemplify or is it outdated to learn about siemplify SOAR because there is a course available SOAR analyst but there is no demo or community version available.

You can get in touch with a representative to inquire about a demo here:

I would say the training is still relevant even though some of the UI elements may look changed in Google SecOps.

You may have already found this but there is a public facing demo instance of Google SecOps (lacking SOAR functionality) here:
