EASM vs CSPM
EASM observes assets from the public internet, while Cloud Security Posture Management evaluates cloud-account configuration using provider context and authenticated access.
What is easm vs cspm?
EASM observes assets from the public internet, while Cloud Security Posture Management evaluates cloud-account configuration using provider context and authenticated access.
How does it work?
EASM finds public names, addresses, certificates, and services across providers. CSPM reads cloud inventory and configuration to identify issues such as public storage, permissive networking, weak identity settings, or missing encryption controls.
What can go wrong?
EASM may see an endpoint without knowing its cloud owner, while CSPM may miss external assets outside connected accounts. Multi-cloud, SaaS, and acquisitions make both views necessary.
How can teams detect the problem?
Map public endpoints to cloud accounts and compare EASM candidates with CSPM inventory. Investigate unmatched assets in both directions.
How can teams improve the situation?
Standardize cloud tagging, connect registrar and cloud ownership, and route exposure findings to the account owner with configuration context.
What does a technical example look like?
Public hostname -> cloud load balancer -> cloud account and owner -> security-group review -> monitored endpointThe example uses reserved documentation domains and addresses. Apply the same reasoning to systems you own or are authorized to assess.

How does continuous monitoring help?
A point-in-time check explains the observed state now. Continuous monitoring establishes an expected baseline, repeats the relevant check, and records meaningful state changes so an owner can investigate before a small configuration drift becomes a prolonged security or availability problem. See External Attack Surface Management for the surrounding technical context.
Where does Sentryx Monitor fit?
Sentryx Monitor provides read-only outside-in discovery and monitoring for public hosts, DNS, HTTPS, TLS certificates, baseline security headers, email-security records, and selected network services. It supports evidence and operational follow-up, but it does not replace authorized penetration testing, authenticated vulnerability assessment, or owner validation.
