## Lessons Learned
- **M&A Due Diligence:** Acquired technology stacks often harbor legacy vulnerabilities that act as weak points for the parent company.
- **Data Minimization:** Retaining customer service notes and customer PII in marketing tools increases the blast radius of a breach.
- **Third-Party Risk:** Marketing tools often sit outside the primary hardened production environment, making them attractive targets.
## Recommendations
- **Asset Inventory:** Conduct a comprehensive security audit of all "shadow IT" and tools inherited through acquisitions.
- **Access Control:** Implement strict Principle of Least Privilege (PoLP) for marketing tools to ensure they do not contain customer service notes or physical addresses unless necessary for function.
- **Encryption:** Ensure PII at rest within third-party tools is encrypted or obfuscated.
