Cisco Firepower 4115 NGFW Appliance, 1U | Enterprise, Rack Mount — CON-L1NBD-N9KC931B

Keep critical traffic under control with a firewall platform designed for enterprise security teams that need more than basic packet filtering. The Cisco Firepower 4115 NGFW appliance combines a 1U rack-mount footprint with two NetMod bays, giving architects a compact chassis that can be shaped around site requirements instead of forcing a fixed interface layout. This model is a strong fit for organizations that want a security appliance positioned for serious perimeter enforcement, segmentation, and policy-driven inspection. The modular bay design supports deployment flexibility, which matters when network topology, uplink strategy, or interface mix changes over time. For infrastructure leaders, the value is in the balance: a dense appliance that preserves rack space while still supporting enterprise deployment patterns. For procurement, it represents a firewall class that justifies its place in the stack through chassis quality, modularity, and Cisco’s security portfolio. Choose the Firepower 4115 when the network edge needs a platform that can anchor a security architecture, not just sit in front of it. It is built for teams that plan for growth, change, and long service life.
