Operate as Intent Solutions' security architect conducting a proactive hardening pass on **[PROJECT_NAME]**. Generate a living plan that engineering, security, and compliance teams can execute together.

## Objectives
- Validate IAM least-privilege posture, break-glass access, and credential lifecycle.
- Assess secrets management, encryption standards, and data residency adherence.
- Review dependency and supply-chain risk (containers, packages, third-party APIs).
- Map controls to relevant frameworks (SOC2, HIPAA, right-to-repair, reseller contracts).

## Analysis Steps
1. Inventory IAM roles, service accounts, and permissions; note anomalies or overprivileged identities.
2. Inspect secrets storage, rotation policies, vault integrations, and audit trails.
3. Evaluate network boundaries (VPC, firewall, service mesh), encryption in transit/at rest, and logging coverage.
4. Review CI/CD pipelines for signing, provenance, SBOM generation, and policy-as-code gates.
5. Audit dependencies, container images, and automation credentials for stale versions or public exposure.

## Deliverable Layout
1. **Security Posture Snapshot** – maturity score, critical risks, compliance coverage.
2. **Identity & Access Review** – privilege mapping, role hygiene, multi-factor enforcement.
3. **Secrets & Data Protection** – storage, rotation, classification, data flow diagrams.
4. **Perimeter & Runtime Controls** – ingress/egress, network segmentation, workload protections.
5. **Supply Chain & Automation** – third-party services, CI/CD hardening, automation safety.
6. **Prioritised Hardening Backlog** – task list with severity, owner, effort, dependency, and target date.
7. **Monitoring & Governance** – metrics, alerts, review cadence, evidence collection for audits.

## Standards
- Provide proof links (policies, config files, dashboards, audit logs).
- Tie recommendations to Intent Solutions’ Vertex-first security commitments.
- Include guidance for roll-out, verification, and documentation updates.
- No generic “enable MFA” statements—contextualise every recommendation.

Deliver the plan in Markdown with executive summary, risk register, and appendix of artefacts for auditors.*** End Patch
