N3K-SEC-5Y Use Case
PCI-DSS Microsegmentation in a Global Financial Data Center
A multinational bank deploys N3K-SEC-5Y-NX-OS Security on its XF Nexus 3K fabric to enforce PCI-DSS microsegmentation between payment processing and analytics servers. Leveraging NX-OS Security’s granular ACLs and VXLAN controls, the bank isolates cardholder data traffic, blocks unauthorized lateral movement, and automates policy consistency across 10+ global sites. Benefit: Achieves real-time compliance validation, reduces breach surface by 85%, and accelerates audit readiness—all without performance degradation.
Zero-Trust Edge Security for Retail Store Networks
A national retail chain integrates N3K-SEC-5Y-NX-OS Security on XF Nexus 3K switches at store and warehouse edges to enforce zero-trust policies for IoT devices, POS terminals, and guest Wi-Fi. Using dynamic Secure Group Tags (SGTs) and TrustSec segmentation, the IT team automatically classifies and isolates devices, blocks unauthorized access, and maintains a single policy framework from HQ to 200+ locations. Benefit: Delivers 60% fewer security incidents, simplifies policy updates by 70%, and ensures consistent visitor privacy and PCI compliance.
Real-Time Threat Detection and Automated Response for Healthcare Networks
A large hospital network applies N3K-SEC-5Y-NX-OS Security on XF Nexus 3K switches to integrate with its SIEM and endpoint detection systems. By enabling IDS/IPS modules and NetFlow telemetry, the network team detects anomalous lateral movements to medical devices, triggers automated quarantine of compromised VLAN segments, and streams flow data to their SOC dashboard. Benefit: Improves mean time to detection by 50%, prevents ransomware propagation across clinical zones, and strengthens HIPAA compliance with continuous, policy-driven enforcement.

Yes. N3K-SEC-5Y enables Cisco TrustSec for scalable network segmentation and identity-based policy enforcement.
Is software support and maintenance included with the N3K-SEC-5Y license?
