Cisco Identity Services Engine SNS-3815 Appliance

The Cisco Identity Services Engine SNS-3815 (SNS-3815-K9) is a purpose-built, high-performance security policy appliance designed to deliver centralized identity and access control across large-scale enterprise networks. Built on the Cisco SNS 3800 Series hardware platform, the SNS-3815 runs Cisco ISE software and provides network access control (NAC), device profiling, guest lifecycle management, and Security Group Tagging (SGT) enforcement in a single integrated solution. The appliance is engineered to support enterprise-grade deployments requiring high availability, scalability, and consistent policy enforcement across wired, wireless, and VPN endpoints.

The SNS-3815 is positioned as a large-node appliance within the ISE deployment hierarchy, suitable for operation as a standalone node or as a dedicated Policy Service Node (PSN), Policy Administration Node (PAN), or Monitoring and Troubleshooting Node (MnT) in distributed ISE deployments. Its hardware specifications support large concurrent session counts and high RADIUS transaction throughput, making it appropriate for campus, data center, and hybrid cloud access control scenarios. Integration with Cisco TrustSec, Cisco DNA Center, Cisco Stealthwatch, and third-party ecosystem tools through pxGrid enables a coordinated security architecture aligned to zero-trust principles.

For organizations operating in the UAE, GCC, EMEA, and APAC regions, the SNS-3815 addresses regulatory and operational requirements for network segmentation, endpoint visibility, and auditable access control. The appliance supports certificate-based authentication, 802.1X enforcement, TACACS+ for device administration, and posture assessment workflows. Omnixon Global supplies this appliance to enterprise IT, government, and data center customers across these regions, supporting deployments that demand consistent policy governance at scale.

Ideal for

• Large enterprise 802.1X network access control for thousands of concurrent wired and wireless endpoints across campus and branch environments
• Zero-trust segmentation enforcement using Cisco TrustSec Security Group Tags (SGT) to restrict lateral movement across data center and enterprise networks
• Centralized TACACS+ device administration and privilege management for routers, switches, firewalls, and other network infrastructure
• Guest lifecycle management including self-registration portals, sponsor approval workflows, and time-limited network access for visitors and contractors
• Endpoint profiling and device visibility to automatically classify and apply appropriate access policies to IoT, OT, BYOD, and managed devices
• Distributed ISE Policy Service Node (PSN) deployment in high-availability architectures serving regional offices across multi-site enterprise networks
