What is the default threshold of alerts needed to trigger an alarm in Tenable.SC?

The default threshold for triggering an alarm in Tenable Security Center is set to 1 alert. This means that as soon as an individual alert is generated, it can initiate an alarm based on the defined policies and configurations within the platform. This functionality is essential for ensuring that security teams can respond to potential threats as promptly as possible, allowing for immediate action when issues are detected, even if they are singular events.

Setting the threshold to 1 alert provides a proactive security posture, enabling organizations to begin investigations and mitigations without delay. Other thresholds would imply a requirement for multiple alerts, which could lead to delays in response and potential exposure to vulnerabilities.
