Case Study: One of Eastern Europe's Largest Financial Institutions achieves 100% DDoS mitigation, zero downtime, and no financial losses with NETSCOUT Sightline and TMS

NETSCOUT Assists Eastern European Institution in Protecting Client Financial Accounts from DDoS Disruptions and Theft

One of the largest financial institutions in Eastern Europe, undergoing a major rebranding and reconnecting with millions of clients, suffered a massive DDoS that knocked out more than 90% of its customer‑facing services, depleted network resources and put its Cybersecurity Risks Prevention team’s KPIs—zero revenue loss, zero service downtime and 100% DDoS mitigation—at risk.

NETSCOUT deployed Sightline with the on‑premise Threat Mitigation System (TMS), outperforming competitors in proof‑of‑concept testing and blocking the largest simulated attacks. In production the solution mitigated 100% of 90+ recorded DDoS incidents (handling attacks up to 160 Gbps), delivered no downtime or client financial losses, restored IT reliability and met the organization’s critical security metrics.
