===============================

The continuous discovery, inventory, classification, and monitoring of an organization's internet-facing assets and their security posture.

Attack Surface Management (ASM) is the continuous process of discovering, cataloging, and monitoring all of an organization's internet-facing assets — domains, subdomains, IP addresses, APIs, cloud resources, and third-party services. Unlike traditional asset management, ASM takes an outside-in approach, seeing the organization as an attacker would and identifying assets that teams may not even know exist.

Modern organizations have rapidly expanding attack surfaces due to cloud adoption, SaaS proliferation, mergers and acquisitions, and shadow IT. ASM platforms continuously pentest for new assets, monitor for changes and misconfigurations, detect exposed credentials and sensitive data, and prioritize risks based on exploitability. The discipline has become essential as organizations cannot protect what they don't know they have.

How APVISO helps with this: APVISO's recon agent performs attack surface discovery as the first phase of every penetration test. It enumerates subdomains, maps exposed services, identifies technology stacks, and discovers hidden endpoints — giving you visibility into your attack surface while simultaneously testing it for vulnerabilities.
