What is Attack Surface Management?
Attack Surface Management — Attack Surface Management (ASM) is the continuous discovery, inventory, classification, and monitoring of all internet-facing assets that belong to an organisation to reduce exposure to threats.
Attack Surface Management Explained in Detail
An organisation's attack surface encompasses every entry point that an attacker could potentially exploit — from domains, subdomains, and IP addresses to cloud buckets, APIs, and third-party integrations.
ASM platforms perform automated, outside-in reconnaissance to discover assets, classify their risk posture, and alert security teams when new exposures appear. This is critical because shadow IT, forgotten staging servers, and misconfigured cloud instances routinely become the initial access vector in breaches.
Why ASM Matters
- Organisations typically undercount their internet-facing assets by 30–40 %.
- Cloud adoption and SaaS sprawl continuously expand the attack surface.
- Regulatory frameworks (ISO 27001, SOC 2, DORA) increasingly require asset visibility.
