Datadog's APM Security View helps businesses efficiently detect and mitigate attacks on their applications by providing security data within the Service Catalog, Service Page, and distributed tracing. It identifies services exposed to security risks, highlights vulnerabilities, shows which services have been attacked, and assists in mitigating active threats. By integrating with Application Security Management (ASM), APM Security View offers code-level insight for quick remediation of attacks and helps reduce exposure to future attacks by identifying risks from known vulnerabilities in third-party libraries.
