Cisco Firepower 2100 Series is used for midrange branch, enterprise edge, VPN, and next-generation firewall deployments. In 2026, buyers usually evaluate it as installed-base hardware, certified remanufactured stock, or a migration source rather than a new long-life platform.
Cisco announced end-of-sale and end-of-life dates for Firepower 2100 Series Security Appliances, with the last day to order affected products listed as May 27, 2025. Buyers should verify current availability, support coverage, and migration path before purchase.
Cisco lists Cisco Secure Firewall 3100 Series as the migration solution for Firepower 2100 Series. Migration planning should include model mapping, interface mapping, software mode, licenses, policy migration, VPN design, and operational testing.
Compare the models by current installed role, inspection throughput, VPN scale, interface requirements, network module needs, HA design, and remaining support window. Larger models historically served higher traffic, more sessions, or heavier inspection workloads.
Firepower 2100 platforms can run Cisco ASA software or Cisco Firewall Threat Defense when supported by the release. The software mode affects feature set, management platform, migration process, license needs, and replacement planning.
Evaluate Firepower 2100 as an installed-base or migration-source platform first: confirm support window, software mode, interface mapping, licenses, VPN design, and HA pair behavior. For new firewall capacity, the comparison should usually move to Secure Firewall 3100 rather than expanding older 2100 hardware.
License requirements depend on ASA or Threat Defense mode and enabled services such as IPS, URL filtering, malware protection, support, and management. Confirm subscription status, renewal limits, and transfer or migration rules before quoting.
Firepower 2100 can support resilient firewall designs when the model, software mode, licenses, and interface layout are planned correctly. For lifecycle planning, also confirm whether the HA pair should migrate together to Secure Firewall 3100.
Map copper, SFP, SFP+, network module, inside, outside, DMZ, failover, management, and VPN interfaces before replacement. Interface mapping is critical because migration often needs equivalent ports, optics, cabling, and firewall zones on the new platform.
Verify exact model, lifecycle status, support eligibility, software mode, inspection throughput, VPN scale, interface needs, network modules, HA design, license subscriptions, migration plan, condition, warranty, and lead time before purchasing.
The Cisco Firepower 2100 Series is a family of four 1RU firewall appliances — the 2110, 2120, 2130, and 2140 — built for use cases from the internet edge to the data center. ASA stateful firewall throughput scales from 3 Gbps on the 2110 to 20 Gbps on the 2140, and every model ships in two variants: an ASA appliance or an NGFW (Threat Defense) appliance. Availability is subject to current stock, so check each model’s page for current price and lead time.
The four models share the same 1RU chassis and base port layout but differ in throughput, uplink speed, expansion, and power redundancy. The 2110 and 2120 use 1G SFP uplinks and a single fixed power supply; the 2130 and 2140 move to 10G SFP+ uplinks, add a network module slot, and support 1+1 redundant power.
| Model | Stateful firewall throughput (ASA) | Threat Defense throughput (FW+AVC+IPS, 1024B) | Data interfaces | Network module slot | Power redundancy | Buy |
|---|---|---|---|---|---|---|
| Firepower 2110 | 3 Gbps | 2.6 Gbps | 12× 1G RJ45 + 4× 1G SFP | — | None (single 250W AC) | ASA / NGFW |
| Firepower 2120 | 6 Gbps | 3.4 Gbps | 12× 1G RJ45 + 4× 1G SFP | — | None (single 250W AC) | ASA / NGFW |
| Firepower 2130 | 10 Gbps | 5.4 Gbps | 12× 1G RJ45 + 4× 10G SFP+ | Yes (1 bay) | 1+1 (dual 400W AC) | ASA / NGFW |
| Firepower 2140 | 20 Gbps | 10.4 Gbps | 12× 1G RJ45 + 4× 10G SFP+ | Yes (1 bay) | 1+1 (dual 400W AC) | ASA / NGFW |
All four models provide twelve 10M/100M/1GBASE-T RJ45 interfaces. The 2110 and 2120 add four 1 Gigabit SFP ports; the 2130 and 2140 add four 10 Gigabit SFP+ ports plus a network module slot, taking the 2130 and 2140 to as many as 24 Ethernet ports. The 2130 is also the NEBS-compliant model in the family.
Match the model to your throughput, uplink, and redundancy needs rather than to port count, since all four share the same twelve RJ45 ports.
Avoid the 2110 and 2120 if your design depends on redundant power or 10G uplinks, since neither is available on those two models.
Each model is sold as two distinct part numbers built on the same hardware. The difference is the software image and how you manage the firewall.
Because the hardware is identical, the model decision (2110 to 2140) and the image decision (ASA or NGFW) are separate. Confirm which image your management platform expects before you order the part number.
Layer23-Switch supplies brand-new original Cisco hardware, backed by a 3-year warranty and RMA service, with global shipping. Layer23-Switch is a Cisco certified partner. Pricing and stock are shown on each model’s product page; because availability is subject to current stock, confirm the current lead time on the exact part number you need before placing a project order.
