## Lessons Learned
- Relying on third-party vendors for handling customer data introduces significant supply chain risk.
- The scope of the compromise must be clearly defined (i.e., confirming corporate systems were untouched).
- Even partial PII exposure (missing last names) necessitates proactive communication due to phishing risk.
## Recommendations
- Conduct immediate and thorough security audits of all downstream third-party vendors handling sensitive customer data.
- Review and enhance contractual agreements with marketing vendors regarding security standards and breach notification timelines.
- Implement robust multi-factor authentication and strict access controls for all vendor platforms interfacing with core customer databases.
