Top attack surface management (ASM) tools are platforms that continuously discover, map, and monitor all digital assets and potential entry points to identify vulnerabilities before attackers exploit them, improving proactive security posture; tools like Wiz, CyCognito, Mandiant ASM, CrowdStrike Falcon Surface, and Qualys CyberSecurity Asset Management differ in asset discovery, risk prioritization, AI-driven insights, and automation, as Wiz uses a unified security graph for full visibility while Mandiant leverages threat intelligence for risk context, so you should choose the top ASM tool based on environment complexity and need for real-time risk prioritization
