Healthcare Data Security: Best Practices, ETL Risk & Reliability
A leading U.S. healthcare products and services company was running critical analytics on an aging ETL estate with weak controls and frequent issues. Teams faced:
User access gaps and no formal password policies.
No monitoring of SQL Servers and an inconsistent reporting process.
No defined backup/DR and no outage windows for patching/maintenance.
Ongoing performance problems tied to a legacy Informatica application.
The Goals
Establish security best practices across access, passwords, and change windows.
Introduce proactive monitoring and reliable reporting for operations and leadership.
Implement a resilient backup & disaster recovery posture.
Stabilize and speed up ETL performance without disrupting business.
Impact Delivered
Highly secured environment with no observed external threats after remediation.
Recurring incidents eliminated with permanent fixes and clear runbooks.
Efficient use of Memory/CPU/Disk I/O plus capacity planning for the next six months.
Zero data loss under the new DR & backup plans.
Smooth, faster ETL job runs with performance blockers removed—and on-time reporting for stakeholders.
