How do you enforce tagging and governance across many AWS accounts?

Answer
For tagging and governance, I combine tag policies, SCPs, IAM conditions, Config rules, CI/CD checks, cost allocation tags, and remediation workflows. Required tags should be small, consistent, and tied to ownership and billing.
Technical explanation
Governance fails when tags are optional and unused; link them to billing, ownership, access, and automation.
Multi-account governance should combine preventive controls such as SCPs with detective controls such as Config, GuardDuty, Inspector, Security Hub, CloudTrail, and Access Analyzer.
Central security, logging, and networking accounts reduce blast radius and protect evidence from workload account compromise.
Every control needs an owner, exception process, alert route, and remediation workflow or it becomes shelfware.
Hands-on example
1. Create a multi-account sandbox or use separate dev/security/logging accounts to test the control pattern.
2. Enable the relevant organization-level service or guardrail, then generate a controlled finding or denied action.
3. Route findings to Security Hub, EventBridge, ticketing, SIEM, or an incident channel with ownership metadata.
4. Document the exception process, remediation automation, and evidence required for audit.
