## Lessons Learned
- **Supply Chain Vulnerability:** Marketing and automation platforms often hold significant PII and represent a "soft target" compared to hardened financial databases.
- **Data Retention:** Storing data dating back to 2018 in an active marketing platform increases the "blast radius" of a breach.
- **Third-Party Risk:** Incident response is dependent on the transparency and security posture of third-party vendors.
## Recommendations
- **Vendor Risk Management:** Conduct regular security audits and penetration testing of third-party marketing partners that handle customer PII.
- **Data Segregation:** Ensure that sensitive data (passports/payment info) remains physically and logically separated from marketing platforms.
- **Encryption at Rest:** Ensure all PII, including geolocation and contact info, is encrypted within third-party environments.
- **Principle of Least Privilege:** Limit the volume of data shared with marketing platforms to only what is necessary for active campaigns.
