Authorized monitoring
Ownership checks keep scans on assets you control and help keep abuse out.
Scheduled scans
Regular checks catch exposure drift while it is still a cleanup task, not an incident.
Retest after fixes
Confirm from the outside that the change actually reduced exposure.
Understand the finding. Know what to fix first.
Basic and Premium include guided analysis so your team can read findings, set fix order, and validate remediation without waiting on a consultant.

Compound risk analysis
