Series Overview
Cisco Firewall 4100 is built for organizations that need more performance and deployment flexibility than mid-range firewall appliances. Within a broader Cisco Security architecture, the platform is commonly deployed at enterprise internet edges, data center perimeters, regional security hubs, private cloud boundaries, VPN aggregation points, and inspection zones where high traffic volume and strong security controls must work together.
In a typical deployment, a Cisco Firewall 4100 appliance protects users, applications, servers, partner connections, remote sites, cloud access, VPN tunnels, and internet-facing services. Depending on the selected software image, the appliance may run Cisco Secure Firewall Threat Defense for next-generation firewall services or Cisco Secure Firewall ASA software for ASA-style firewall and VPN operations.
The main value of Cisco Firewall 4100 is its balance of performance, modularity, and security-service flexibility. Buyers can size the platform around firewall throughput, IPS inspection, malware defense, URL filtering, VPN scale, network module requirements, high availability, clustering, and management preferences. Because some 4100 environments include earlier-generation models and software limits, the final part number should be selected after reviewing the exact appliance model, software version, support status, and planned security roadmap.
Licensing and Part Number Guidance
Choosing the correct part number for Cisco Firewall 4100 depends on the appliance model, software image, FXOS version, throughput requirement, interface module, VPN design, security subscription bundle, management platform, support term, and activation method.
Threat Defense deployments commonly involve Smart Licensing, a base firewall entitlement, and optional subscriptions such as IPS, Malware Defense, URL Filtering, and related threat services. ASA deployments may involve ASA licensing, strong encryption, security context requirements, Cisco Secure Client needs, VPN scale, and support coverage.
Buyers should confirm whether the request is for a newer FPR-4112, FPR-4115, FPR-4125, or FPR-4145 model, or for an earlier FPR-4110, FPR-4120, FPR-4140, or FPR-4150 environment. They should also identify whether the order is for a single appliance, HA pair, cluster design, subscription renewal, ASA-to-FTD migration, network module expansion, dedicated IPS deployment, replacement firewall, or support renewal. The quote should clearly separate hardware SKUs, software image, security subscriptions, VPN requirements, network modules, transceivers, management needs, accessories, and support contracts.

What to Check Before Requesting a Quote
Before requesting a quote for Cisco Firewall 4100, confirm the appliance model, software image, FXOS version, required throughput, interface count, network module need, VPN requirement, security subscriptions, management platform, support term, and Smart Account status.
You should also define whether the request is for a new internet-edge firewall, data center edge firewall, HA pair, cluster, dedicated IPS deployment, subscription renewal, ASA-to-FTD migration, Cisco Secure Client requirement, network module expansion, support renewal, spare appliance, or replacement project. Each case can change the final SKU and licensing scope.
For existing environments, prepare the current inventory first. This should include serial number, appliance model, software image, FXOS version, current license status, enabled subscriptions, management platform, interface usage, VPN usage, installed network modules, support coverage, and renewal date.
Activation and Delivery Notes
After the correct Cisco Firewall 4100 part number is selected, activation depends on the software image, Smart Account, license type, FXOS version, management platform, and subscription bundle. Many Cisco Secure Firewall Threat Defense deployments use Smart Licensing or Smart Licensing Using Policy for entitlement visibility and reporting. Subscriptions such as IPS, Malware Defense, and URL Filtering should match the number of appliances and the selected subscription term.
For hardware delivery, compatibility should be checked before shipment. Appliance model, software image, FXOS version, network modules, transceivers, management platform, interface needs, encryption requirement, and support coverage should match the planned firewall design. For renewals, replacements, or migrations, review the current license and support status first. This helps prevent ordering delays and keeps the selected SKU aligned with the real security requirement.
Cisco Firewall pricing depends on your license type, deployment model and support requirements.
