Continuous Monitoring

Attack Surface Monitoring

Attack surface monitoring continuously tracks all externally visible attack surfaces of your suppliers — domains, IPs, subdomains, open ports and exposed services.

Attack Surface Monitoring (ASM) is the continuous inventory and monitoring of all externally visible and potentially vulnerable components of a supplier — their digital attack surface.

What belongs to a supplier's attack surface?

A supplier's external attack surface includes: all registered domains and subdomains, IP addresses and hosting infrastructure, open ports and exposed services, SSL/TLS certificates and their expiry dates, web applications and APIs, cloud services and S3 buckets, email security configuration (SPF, DKIM, DMARC) and software versions and known vulnerabilities (CVEs).

Complete ASM without the effort

360TPRM automatically maps the complete attack surface of every supplier — updated daily, without requiring suppliers to actively participate.

ASM as the foundation for TPRM risk assessments

Attack surface monitoring provides the objective, externally verifiable data basis for TPRM risk assessments. While questionnaires rely on self-reporting, ASM shows the actual security posture. NIS2 and DORA require risk-based assessments — ASM is the technical foundation.

Unknown attack surfaces are the biggest risk

80% of all cyberattacks exploit external, often unknown attack surfaces. ASM makes the invisible visible — including at suppliers.

FAQ

Does ASM differ from penetration testing?+

Yes — penetration testing is a one-off, active test. ASM is continuous and passive: it maps and monitors the attack surface permanently without active intervention.

Do suppliers need to consent to ASM?+

No — 360TPRM relies exclusively on external, publicly available information. Supplier consent isn't required.
