Cyber Risks

Attack Surface Management

ASM makes the invisible visible — and is the foundation for proactive cyber risk management at your own organisation and suppliers.

Attack Surface Management (ASM) is the continuous process of inventorying, monitoring and reducing all externally vulnerable components of an organisation.

ASM vs. attack surface monitoring

Attack surface monitoring (passive) detects and watches the attack surface. Attack surface management (active) goes further: identifying the complete attack surface including shadow IT, assessing and prioritising risks, actively reducing the attack surface (closing unnecessary services, patching), continuously re-evaluating after changes, and integrating with vulnerability management and patch processes.

From detection to reduction

360TPRM handles the monitoring side of ASM for all suppliers — and delivers the data needed for active reduction measures.

ASM in a supplier context

In a TPRM context, ASM means: fully mapping each supplier's external attack surface, updating daily as it changes, tracking trends (is a supplier's attack surface growing or shrinking?), benchmarking against the industry average, and escalating on critical exposure.

Unknown assets are the biggest risk

Security teams often know only 70-80% of their own digital assets (Gartner). For suppliers, visibility is even lower — without ASM.

FAQ

What is shadow IT in an ASM context?+

Unauthorised IT resources operated without the knowledge of the IT department. ASM makes shadow IT visible too — at your own organisation and at suppliers.

How does ASM differ from penetration testing?+

Penetration testing is active, point-in-time and requires authorisation. ASM is passive, continuous and based on external data.
