Engines, providers, and integrations
This page is the short version. It is here so you can check what Sentinel supports without digging through the longer runtime and configuration pages.
If you want the mechanics behind any of this, the deeper explanation lives in Engines and runtime and Configuration. This page is just the compact reference view.
