Attack Surface Monitoring vs DAST: Why security teams need both

Attack Surface Monitoring (ASM) and Dynamic Application Security Testing (DAST) are increasingly essential components of modern cybersecurity, necessitating a combined approach to effectively mitigate risks posed by expanding digital infrastructures. As organizations grow their cloud environments, applications, and external services, their attack surfaces widen, making it crucial to identify and secure internet-facing assets that may otherwise go unnoticed or unmanaged. ASM focuses on discovering these assets, such as APIs, cloud resources, and shadow IT, from an external perspective, while DAST simulates real-world attacks to find vulnerabilities within active applications. Traditionally treated as separate functions, the integration of ASM and DAST addresses blind spots by ensuring that newly discovered assets are immediately tested for vulnerabilities, enhancing security posture through automated scan targeting and context-driven prioritization. This unified strategy, exemplified by platforms like Detectify, combines continuous asset discovery with dynamic testing, supported by real-time threat intelligence, to provide comprehensive protection against potential exploits, ultimately enabling organizations to better manage their attack surfaces and prioritize remediation efforts based on real-world risks.
