Did DDOG just repackage ESTC security?
No, DataDog’s security product is of their own making. They use ES in their infrastructure as the datastore to index and search the data ingested from the DataDog Proprietary Agents installed. They use other open source tools as well like Kafka. And the product they sell is the DataDog dashboards for visualization, alerting, ML, and other features. But to be clear, they are not reselling Elasticsearch in any way. Certainly not any more than Uber or Lyft or GrubHub do in their final product. They just use it in the stack that delivers a Proprietary Software Product. Even if it is a core to the infrastructure.
You can see a visualization of what the DataDog stack looks like (at least at the time) here:

The security for the Elastic Stack is layered into various subscriptions levels. But none of them are in a license which could be repackaged and sold as a solution.
But it is further evidence of the convergence of these use cases, which ESTC has been talking about for some time.
