-## How about pre-built Actions?
-
-_Work-in-progress: we plan to release pre-built actions end of April 2024._
-
-Actions can be configured to do almost any tasks, but it's best to use pre-built ones if available.
-Pre-built actions have pre-configured inputs to perform tasks for commonly used products.
-
-Here are a few examples:
-
-- `URLScan` Perform a security scan on a given URL
-- `VirusTotal` Get detailed report for a malware sample
-- `Microsoft Defender` Trigger a scan on a specific file
-- `EmailRep` Retrieve reputation information for a given email address
-- `GeoIP Lookup` Get the geographical location information for a given IP address.
-- `Slack` Send a message to a specific channel on Slack
