Cisco Secure Firewall 1200 Model Comparison

The Cisco Secure Firewall 1200 Series is built for distributed enterprises, branch offices, retail sites, and smaller internet edges. It covers six hardware variants: the compact 1210CE, 1210CP, and 1220CX, followed by the 1U rack-mount 1230, 1240, and 1250. The family begins at 6 Gbps of published threat-defense throughput and scales to 18 Gbps, but throughput alone is not enough to select the correct appliance.

A realistic firewall comparison must include inspected traffic, TLS decryption, VPN demand, concurrent sessions, new connections per second, physical interfaces, software image, management, high availability, and subscription term. This guide uses Cisco's Threat Defense figures for like-for-like hardware sizing and separates them from the higher stateful-firewall numbers published for ASA software.

Quick Answer: Which Secure Firewall 1200 Model Fits?

Choose the 1210CE for a compact branch with 1G copper connectivity and up to 6 Gbps of published threat-defense performance. Choose the 1210CP when the same performance tier also needs four powered Ethernet ports and a total PoE budget of 120W.

Choose the 1220CX when a compact appliance needs 10G fiber connectivity, more sessions, or a higher inspected-throughput ceiling. Its two SFP+ interfaces are the key physical difference from the 1210 tier.

Choose the 1230 or 1240 for a rack-mounted branch edge requiring four SFP+ interfaces, a field-replaceable 960GB SSD, and more capacity. The 1240 provides more headroom than the 1230 for threat defense, TLS decryption, connections, sessions, and VPN peers.

Choose the 1250 when the branch requires the highest scale in the family, 2.5G copper interfaces, or up to 18 Gbps of published FW + AVC + IPS throughput. It is the strongest 1200 Series option, but larger campus, data-center, or internet-edge designs may require comparison with Cisco's higher firewall families.

The figures above are Cisco's published Threat Defense results using the test conditions identified in its data sheet. Production performance varies with packet size, application mix, enabled services, policy complexity, logging, software release, and traffic direction. Treat the table as a normalized comparison, not as a promise that every deployment will deliver the laboratory maximum.

Cisco Secure Firewall 1210: Compact Branch Entry

The 1210 tier is offered as the 1210CE and 1210CP. Both provide eight 1G copper data interfaces in a compact desktop form factor and share the same published security performance. The 1210CE is the conventional compact model. The 1210CP adds PoE on four ports with a total delivery budget of up to 120W, which can simplify a small site with phones, cameras, or access points.

The 1210 is not merely selected by user count. A small branch with encrypted cloud applications can put more load on TLS inspection than a larger site with mostly trusted private traffic. Cisco publishes 1 Gbps for TLS decryption on this tier, 35,000 maximum new connections per second with AVC, 200,000 concurrent sessions with AVC, and 200 maximum VPN peers under Threat Defense. Compare those limits with measured or forecast demand before accepting the headline 6 Gbps figure.

Use the 1210 when compact installation, 1G connectivity, and moderate scale fit the design. If the WAN or LAN handoff is already 10G, the 1220's SFP+ interfaces may make it the practical minimum even when the current traffic rate is below 6 Gbps.

Cisco Secure Firewall 1220: Compact with 10G Uplinks

The 1220CX keeps the compact form factor but adds two 1/10G SFP+ interfaces alongside eight 1G copper ports. Cisco publishes 9 Gbps for FW + AVC + IPS, 10 Gbps for IPsec VPN with fastpath, 1.5 Gbps for TLS decryption, 300,000 concurrent sessions with AVC, and 300 VPN peers.

This makes the 1220 a strong fit when the site has 10G fiber handoffs, when a pair of high-speed interfaces is required for inside/outside or redundant connectivity, or when the 1210's connection and inspection limits leave too little headroom. It can also be easier to place in locations without a full rack than a 1U appliance.

Do not choose the 1220 solely because its VPN figure is higher than its published firewall figure. The test methods differ, and a real deployment normally mixes internet access, inspection, encrypted sessions, management traffic, and logging. Size against the combined policy path that production traffic will use.

Cisco Secure Firewall 1230 and 1240: Rack-Mount Branch Appliances

The 1230 and 1240 move into a 1U rack-mount format. Both provide eight 1G copper interfaces and four 1/10G SFP+ slots, a dedicated 1G management interface, and a field-replaceable 960GB SSD. This physical layout is better suited to a structured network rack and offers more fiber connectivity than the compact models.

The 1230 publishes 13 Gbps for FW + AVC, 9 Gbps with IPS added, 2.5 Gbps for TLS decryption, 13 Gbps for IPsec VPN, 400,000 concurrent sessions with AVC, and 500 VPN peers. It is often the first 1U model to evaluate when rack installation and four SFP+ interfaces are requirements.

The 1240 increases FW + AVC to 18 Gbps, FW + AVC + IPS to 12 Gbps, TLS decryption to 3.2 Gbps, concurrent sessions to 600,000, maximum new connections with AVC to 70,000 per second, and VPN peers to 1,000. That additional headroom can matter for a regional branch aggregating smaller sites or a location with more internet breakout and remote-access demand.

Both models use a single integrated power supply according to Cisco's hardware specification. An active/standby firewall pair provides appliance-level high availability, but it does not create dual internal power supplies within each chassis. Power feeds, upstream/downstream switching, and cabling should be designed as part of the complete failure path.

Cisco Secure Firewall 1250: Highest Capacity in the Series

The 1250 is the largest 1200 Series model. It upgrades the eight copper data interfaces from 1G to 2.5GBASE-T while retaining four 1/10G SFP+ slots. Cisco publishes 24 Gbps for FW + AVC, 18 Gbps for FW + AVC + IPS, 22 Gbps for IPsec VPN, and 4.1 Gbps for TLS decryption.

Scale also rises to one million concurrent sessions with AVC, 100,000 maximum new connections per second with AVC, 1,500 VPN peers, and 15 virtual router instances under the published Threat Defense specifications. These limits make the 1250 suitable for larger branches and distributed-enterprise hubs where the 1230 or 1240 would operate too close to its ceiling.

The 2.5G copper ports are useful only when the connected switching and cabling can negotiate that speed. If every production handoff is SFP+, their presence should not outweigh inspection or scale requirements. Conversely, a multi-gigabit LAN design may make the 1250 necessary even when average internet traffic looks modest.

How to Size a Secure Firewall 1200

Start with inspected throughput. Estimate busy-hour traffic in both directions, then identify which flows receive application visibility, intrusion prevention, URL filtering, malware inspection, or other services. Use FW + AVC + IPS as the closer planning column when IPS is part of the production policy. Add growth and failure headroom rather than selecting a model whose test maximum exactly equals today's traffic.

Measure TLS inspection separately. Encrypted web and application traffic can make TLS decryption the limiting figure. Compare the proportion of eligible encrypted traffic with the model's TLS result, account for exclusions, certificate handling, and privacy policy, and test representative applications. A firewall that forwards 12 Gbps with IPS does not necessarily decrypt 12 Gbps of TLS.

Check connection behavior. Retail, guest Wi-Fi, DNS-heavy services, APIs, and short-lived cloud connections can create high connection rates even when bandwidth is moderate. Review peak concurrent sessions and new connections per second rather than relying on average user count.

Plan VPN by traffic and peers. Count site-to-site tunnels, remote-access users, and the bandwidth that remains during a failover. Maximum peer count and IPsec throughput answer different questions. Authentication, posture, and management dependencies should also be included in the remote-access design.

Validate the interfaces. Map every WAN, LAN, DMZ, HA, management, and migration connection to a physical port. Include optics, copper transceivers where supported, fiber type, and any switching required to avoid single points of failure.

ASA Software vs Secure Firewall Threat Defense

The 1200 Series can be ordered with ASA or Secure Firewall Threat Defense software. ASA mode can be appropriate for organizations preserving an established ASA operating model and feature set. Threat Defense is the next-generation firewall path for application visibility and control, intrusion prevention, and integrated security services.

Do not compare the ASA stateful-firewall throughput column with the Threat Defense FW + AVC + IPS column as if they represented the same workload. ASA figures are higher on several models because the enabled functions and test profiles differ. First choose the software and inspection policy that meets the security requirement; then size within the corresponding table.

If the migration begins from older ASA or Firepower hardware, inventory NAT, VPN, routing, high availability, identity, inspection, logging, and management dependencies. Hardware capacity is only one part of the project. The Cisco ASA vs Firepower guide explains the broader platform and software distinction.

High Availability, Management, and Licensing

Cisco lists active/standby high availability for the 1200 Series with Threat Defense and states that multi-instance is not supported. An HA design normally requires two compatible appliances, consistent software and entitlement planning, and redundant network paths. Confirm whether subscriptions, support, and management capacity are sized for both members.

The hardware PID identifies the appliance and initial software image, but a complete order can also include security subscriptions, management entitlements or appliances, support, SSD or mounting accessories, optics, and power items. Subscription packaging changes over time, so match required services to Cisco's current ordering guide rather than copying an old bill of materials.

Management architecture affects both cost and operations. Decide whether the site will use local management, centralized Firewall Management Center, or Cisco's current cloud-management option, and verify feature support for the chosen software release. Include log retention, event volume, backup, role-based access, and upgrade process in the design.

Which Model Should You Buy?

Small branch, all-copper: The 1210CE is the starting point. Use the 1210CP when four PoE ports and the 120W budget remove the need for a separate small PoE switch and the topology remains supportable.

Compact branch with fiber or 10G: The 1220CX is the natural step up. Its SFP+ interfaces and higher performance provide more flexibility without requiring a 1U appliance.

Standard rack-mounted branch: Choose between 1230 and 1240 based on inspected throughput, TLS load, connections, sessions, and VPN scale. The 1240 is the safer choice when forecasts place the 1230 near its limit or when the site aggregates other branches.

Large branch or regional hub: Evaluate the 1250 for its 2.5G copper ports, 18 Gbps threat-defense result, and higher session and VPN scale. If the 1250 still lacks power redundancy, interfaces, performance, or organizational scale, compare a higher Cisco Secure Firewall family instead of operating at the edge of the platform.

Buying Checklist

• Choose ASA or Threat Defense before comparing performance figures.
• Use inspected-throughput and TLS-decryption requirements, not raw firewall throughput alone.
• Record peak concurrent sessions and new connections per second.
• Count site-to-site and remote-access VPN peers and their combined traffic.
• Map WAN, LAN, DMZ, HA, management, and migration links to actual interfaces.
• Confirm compact, wall, desktop, cabinet, or rack mounting requirements.
• Include the second appliance and redundant paths if active/standby HA is required.
• Add subscriptions, management, support, optics, mounts, power, and spares to total cost.
• Validate the final configuration against the current Cisco ordering guide.

Checking Current MSRP

Secure Firewall part numbers differ by model and initial software image, and a hardware-only price does not represent the full protected-site cost. Search the Cisco security catalog on GlobalPriceList.com for current appliance MSRP, then compare reseller proposals using the same subscriptions, term, support, management, optics, and HA quantity.
