runZero Reviews, Ratings & Features 2026 | Gartner Peer Insights

Cyber asset attack surface management (CAASM) is focused on enabling security teams to overcome asset visibility and exposure challenges. It enables organizations to see all assets (internal and external), primarily through API integrations with existing tools, query consolidated data, identify the scope of vulnerabilities and gaps in security controls. These tools then continuously monitor and analyze detected vulnerabilities to drill down the most critical threats to the business and prioritize necessary remediation and mitigation actions for improved cyber security.
