Attack Surface Management: The Foundation of Effective External Threat Defense

In today’s rapidly evolving digital ecosystem, organizations are more exposed than ever. From cloud misconfigurations and unsecured APIs to forgotten subdomains and third-party integrations—the modern attack surface is vast, dynamic, and often underestimated.

Yet, most breaches don’t start with a sophisticated exploit—they begin with exposed assets no one was monitoring.

That’s where Attack Surface Management (ASM) becomes indispensable.

ASM provides continuous, real-time visibility into your entire external-facing environment. It helps security teams identify unmanaged assets, shadow IT, vulnerable services, and other weak links before attackers find them.

When integrated into a broader External Threat Management strategy, ASM enables proactive risk reduction, smarter threat prioritization, and faster incident response.

In the age of external threats, you can’t defend what you don’t know exists. Managing your digital perimeter isn’t just a best practice—it’s a necessity for resilience.
