A fintech startup caught an attack its previous vendor missed
The problem
The fintech's legacy perimeter firewall passed a 'compliant' audit but had not been updated in 14 months. A lateral-movement probe went undetected for nine days.
What we did
We deployed a unified threat management appliance with IDS/IPS signatures updated daily, split the network into three VLANs (customer data, internal tools, public Wi-Fi), and added a managed SOC retainer.
"The UTM blocked an attack at 2am that our previous vendor would have found three days later. Flash Code answers at 2am like it's 2pm."
