Case Study: Dynamic Business Systems achieves complete DDoS protection and zero downtime with Corero’s First Line of Defense

High-Profile Wall Street Firm Banks on Corero's First Line of Defense to Stop Costly DDOS Attacks

Dynamic Business Systems (DBS), a network design and security firm, was supporting a high‑profile Wall Street client that was hit by relentless DDoS attacks. Thousands of attacking IPs overwhelmed the firewall (peaking at about 95% utilization), manual IP blocks and the firewall vendor’s built‑in DDoS feature proved ineffective, and the attacks caused site outages and lost business.

DBS deployed Corero’s First Line of Defense, which was installed in 45 minutes and immediately stopped both application‑layer and network‑layer attacks, restoring normal traffic flow and dropping firewall utilization to single digits. The solution eliminated downtime, protected the client’s IT infrastructure, and prompted purchase of a second unit for disaster recovery.
