Cisco Secure 3105 Next-Generation Security Appliance Firewall

The Cisco FPR3105-NGFW-K9 is a next generation firewall appliance that gives midsize and growing enterprises a strong line of defense without adding complexity. It belongs to the Cisco Secure Firewall 3100 series, and it is built to keep critical applications, users, and data protected even when advanced inspection features are active.

Inside the chassis is a CPU architecture that was designed specifically for security workloads. This hardware drives high throughput for firewall, encryption, and deep threat inspection tasks, so you can enable the protections you need without sacrificing performance. The appliance supports both ASA and Firewall Threat Defense software. That dual-software approach lets a team deploy it as a traditional firewall, switch it to a dedicated intrusion prevention sensor, or run a mix of both functions as requirements change.

For networks that rely on complex segmentation, the unit offers Q-in-Q capabilities on inline and passive interfaces. By carrying up to two 802.1Q headers in every packet, it helps service providers, multitenant environments, and large campuses preserve VLAN separation while inspecting traffic end to end.

The Cisco Secure Firewall 3105 fits naturally in branch offices, regional data centers, and hybrid work environments where zero trust principles are becoming standard. Whether you need to protect a remote workforce, segment departmental traffic, or ensure encrypted connections between sites, this platform provides the flexibility and resilience that security teams expect from Cisco.

Highlights:

• Next generation security appliance that defends against modern threats
• Runs either ASA or Firewall Threat Defense software for flexible deployment
• Q-in-Q support enables stacked VLAN inspection with up to two 802.1Q headers per packet
• Purpose-built CPU architecture optimizes firewall, encryption, and inspection performance
• Operates in firewall mode or as a dedicated intrusion prevention system
