In this white paper, we review what attack surface management is, why it's needed, and how organizations can use its principles to improve the security of their internet-facing assets. We break attack surface management down into seven key steps you can use to ensure your organization's external attack surface is protected.
Attack surface management is a continuous discipline, not a one-time scan. We walk through how to inventory every internet-facing asset across cloud providers, subsidiaries, and shadow IT; how to enrich that inventory with the context security teams need to act; and how to prioritize remediation based on real-world risk rather than raw vulnerability counts.
The framework draws on our work helping organizations across financial services, healthcare, software, and the public sector reduce external risk. Whether you are formalizing an ASM program for the first time or maturing an existing one, the seven steps inside provide a repeatable approach you can adapt to your environment.
