AWS inspector: Amazon Inspector usage/cost notes for machine image scanning

Service: inspector · 2026-10-29 · Documentation low

File: inspector/latest/user/usage.md

Summary

Adds billing/metering details explaining that machine image scanning cost is the sum of initial scans plus rescans in the last 30 days, that failed on-demand scans are not metered, and that the free trial does not apply to on-demand machine image scans.

Security assessment

The change is purely about pricing/metering behavior of Amazon Inspector machine image scans and free-trial eligibility; it contains no security controls, permissions, or vulnerability information.

Evidence

+    * Machine image scanning: cost reflects the sum of the number of initial machine image scans + machine image rescans in the last 30 days. This includes on-demand machine image scans that completed successfully. Amazon Inspector doesn't meter an on-demand scan that fails. For more information, see [Running on-demand machine image scans with Amazon Inspector](./machine-image-on-demand.html).
