ASA5550-BUN-K9 Use Case
High-Availability Perimeter Firewall for Enterprise Data Center
In a global financial services data center, two ASA5550-BUN-K9 appliances are deployed in an active/standby HA cluster to protect the DMZ and back-office VLANs. Eight 1 GbE ports enforce strict network segmentation for trading, management and guest networks, while the dedicated FE port handles OOB management. Integrated 3DES/AES encryption and Cisco ASA Firewall Edition deliver stateful inspection, intrusion prevention and advanced threat defense. Benefit: Sub-second failover with zero service interruption, 5 Gbps sustained throughput and consistent policy enforcement ensure 24/7 availability for critical online banking applications.
Secure Site-to-Site VPN Connectivity for Distributed Branch Offices
A multinational retail chain secures connectivity between its central data center and 120 branch locations using ASA5550-BUN-K9 appliances at each site. The 8 x 1 GbE interfaces aggregate POS, VoIP and inventory systems while 3DES/AES VPN tunnels encrypt customer and transaction data. Cisco ASA Firewall Edition enforces access control and NAT policies across all VPN peers. Benefit: Scalable support for up to 500 concurrent IPsec tunnels, end-to-end data confidentiality, centralized policy management and compliance with global data-privacy regulations.
PCI DSS-Compliant E-Commerce Application Segmentation and Threat Prevention
A large online retailer uses ASA5550-BUN-K9 appliances in front-end and application DMZ tiers to segment web servers, payment processing and database clusters. Multi-context firewalling isolates each environment, while Cisco ASA Firewall Edition provides deep packet inspection, IPS and botnet filtering. 3DES/AES encryption safeguards administrator sessions and inter-tier traffic. Benefit: Streamlined PCI DSS certification through network segmentation, automated intrusion prevention, continuous monitoring and 99.99% uptime for high-volume sales events.
