Undetected threats are malicious communications and activities that the organization’s Security Information and Event Management (SIEM) fails to identify and alert the security operation’s team about in the network. That failure is also called a false negative because the SIEM doesn’t catch the threat and deems it benign. Undetected threats can lead to long-dwell breaches in a network and cause damage to the organization. Undetected threats can lead to major data exfiltration and force the company to pay high fines in the wake of reputational damage.
