CSPM usually reads control-plane data through cloud-provider APIs, builds an inventory, and identifies conditions such as publicly reachable storage, disabled logging, overly broad network access, weak encryption settings, or drift from an approved baseline.
The word “posture” matters: CSPM primarily evaluates how cloud infrastructure and managed services are configured and interrelated. A mature process adds ownership, risk context, exceptions, and verified remediation instead of treating every failed check as equally urgent. Tools may also graph possible attack paths or include entitlement analysis, but those additions are not consistent enough to redefine the category.
Key points
Discover and normalizeInventory accounts, subscriptions, projects, regions, services, resources, tags, and important relationships across the supported environment.
Evaluate continuouslyCompare observed settings with organizational policy, provider guidance, and selected control frameworks; detect new resources and configuration drift.
Prioritize and assignAdd exposure, data sensitivity, exploitability, identity reach, and business ownership so teams can act on the findings that matter most.
Remediate safelyProvide instructions or controlled automation, record exceptions, test changes, and confirm that a correction persists.
Important limitationCSPM visibility is bounded by API permissions, supported services, scan timing, and policy quality. A passing configuration check does not establish that application code or activity inside a workload is secure.
