Enhanced Endpoint Security for a Complex 80,000-Servers Infrastructure with Minimal Disruption for a Leading Fintech Giant
Client: Leading Global Financial Institution (FinTech Gaint)
Challenge: Enhancing Endpoint Security Across a Complex 80,000-Server Infrastructure Without Performance Degradation
Over View
A leading global financial institution with a complex IT infrastructure of approximately 80,000 servers faced challenges in balancing endpoint security with system performance. Supporting multiple business lines, the institution required a solution that ensured security compliance while preventing disruptions to mission-critical applications.
Challenges
🔹 Endpoint Security Compliance – Ensuring timely security scans and updates across all servers.
🔹 Performance Degradation – Endpoint security agents caused application slowdowns.
🔹 Business Disruptions – Critical applications experienced lag during trading hours, settlement periods, and peak operations.
🔹 Tight Reporting Timelines – Cybersecurity team required security assessment results within 24 hours.
Solution & Approach
To mitigate these challenges, a strategic, business-aligned security deployment was implemented:
âś… Business Segmentation & Criticality-Based Grouping
- Equity Trading Systems: Trading windows (9:30 AM – 10:00 AM ET & 3:30 PM – 4:05 PM ET).
- Federal Settlement Applications: Peak processing at 7:00 PM ET.
- Algorithmic Trading Systems: Limited execution to off-peak hours.
- General Business Systems: Flexible scan schedules based on resource availability.
âś… Blackout Windows for Critical Business Periods
- Security scans disabled during high-impact trading and settlement times.
- Mission-critical applications remained unaffected.
âś… Resource Capping with Cgroups
- Implemented CPU & memory limits for Tanium agents using Cgroups.
- Prevented excessive resource consumption, ensuring application stability.
âś… Optimized Scan Scheduling & Reporting
- Staggered scan schedules aligned with business priority.
- Security results compiled and reported within 24 hours to the Cybersecurity team.
Outcome
🚀 Zero Downtime for Critical Systems – Trading, settlement, and business applications ran without slowdowns.
⚡ Efficient Security Compliance – Security assessments met the 24-hour reporting window.
📉 Reduced Resource Utilization – Cgroup policies minimized CPU and memory impact.
🛡️ Scalable Security Strategy – Endpoint protection strengthened without disrupting operations.
Conclusion
Through a business-aligned endpoint security strategy, the financial institution successfully maintained compliance without compromising system performance. By segmenting workloads, implementing blackout windows, and optimizing security processes, the organization achieved seamless security enforcement across 80,000 servers while ensuring business continuity.
