SPA-IPSEC-2G Use Case
High-Throughput Branch-to-HQ VPN for Retail Enterprises
A national retail chain deploys the Cisco SPA-IPSEC-2G SPA in Catalyst 6500 and 7600 series platforms to create a dedicated 2 Gbps IPSec tunnel between 200+ branch stores and its headquarters. Leveraging DES/3DES/AES encryption, the solution secures POS transactions, inventory updates, and corporate VoIP traffic over the public Internet. Outcome: Retailers achieve FIPS-compliant data confidentiality, 99.99% uptime, and streamlined centralized management—driving operational efficiency and regulatory compliance.
Data Center Interconnect with AES-Secured Multi-Site Replication
A financial services firm uses the SPA-IPSEC-2G module on Cisco 7600 routers to link three geographically dispersed data centers via AES-256 IPSec tunnels aggregated to 2 Gbps. The deployment enables real-time database replication and disaster recovery synchronization across sites, while 3DES fallback ensures compatibility with legacy systems. Outcome: The firm reduces RPO to seconds, maintains PCI/DSS and GLBA compliance, and minimizes failover risk—all within a single, high-performance WAN link.
Secure Remote Access for Field Engineers Using DES/3DES/AES
An oil & gas operator outfits its Catalyst 6500 backbone with the SPA-IPSEC-2G module to provide field engineers with secure IPSec VPN access over 4G/5G and satellite links. Engineers authenticate via RADIUS and connect to central SCADA systems, leveraging AES encryption for high-value telemetry and control commands. Outcome: The operator achieves end-to-end data integrity, reduces configuration drift, and accelerates issue resolution—enhancing safety and reducing unplanned downtime by 30%.
