The No Action option is assigned when an administrator wants to save the IOC for future use but does not want Falcon to take an enforcement or detection action at that time. In IOC Management, hash indicators can be assigned actions such as Block, Detect Only, Allow, or None/No Action. Block prevents the hash and can show it as a detection when the required prevention policy setting is enabled. Detect Only generates a detection but takes no prevention action. Allow adds the hash to the allowlist and suppresses detection for that indicator. No Action is different from all three: it retains the indicator in IOC Management without blocking it, allowing it, or generating a detection. This is useful when an indicator is being staged, tracked, reviewed, or retained for future activation after validation. It is not an allowlist or blocklist action.
