Explore Advisory & Governance MethodologyFour non-negotiable governance rules.
Progress requires independent review
Unreviewed submissions count as zero. Completion metrics only advance once independent second-line review is accepted.
Enforced Segregation of Duties
Control owners cannot approve their own assessments—enforced automatically at the platform data layer.
Mandatory remediation on failure
An inadequate control rating cannot be submitted without recording a formal finding, named owner, and remediation plan.
Immutable audit trail & advisory AI
AI extraction remains strictly advisory until human sign-off, with every decision recorded in an append-only audit log.
