Protect distributed sites with a firewall platform sized for real enterprise traffic. Cisco Secure Firewall 3105 brings 1U efficiency to branch and campus edge deployments where space is limited but policy enforcement cannot be compromised. It is designed to inspect traffic, segment users and applications, and support security controls that help reduce exposure across the network perimeter. For teams standardizing on Cisco security architecture, this appliance fits naturally into managed firewall environments where consistency matters as much as throughput. The 3105 is a practical choice for organizations that need a dedicated hardware platform rather than a general-purpose server, especially when predictable behavior, appliance-based management, and long-term operational stability are part of the buying criteria. Its compact footprint makes it easier to place at remote sites, while the Cisco Secure Firewall platform supports the control model infrastructure teams expect for policy-driven enforcement. That combination makes the 3105 well suited for organizations replacing aging perimeter devices, extending security to more locations, or building a standardized firewall tier across multiple offices.
