Tenable Identity Exposure

5 reviews

Behind every breach headline is an insecure Active Directory (AD) deployment. AD has become the favored target for attackers to elevate privileges and facilitate lateral movement through leveraging known flaws and misconfigurations. Unfortunately, most organizations struggle with Active Directory security due to misconfigurations piling up as domains increase in complexity, leaving security teams unable to find and fix flaws before they become business-impacting issues. Tenable.ad enables you to see everything, predict what matters, and act to address risk in Active Directory to disrupt attack paths before attackers exploit them.
