Product Overview
ISR4431-SEC/K9 Overview
Cisco ISR4431-SEC/K9 is the Cisco ISR4431/k9 router with Security Bundle. Its other specifications are the same as ISR4431/k9. The published specification for ISR4431-SEC/K9 lists 4 Total onboard WAN or LAN 10/100/1000 ports and 250 W with optional redundancy available to powered devices. It is supplied new factory sealed, with the serial list issued before shipment and 12 months replacement warranty as standard.
Key Benefits
What Owning ISR4431-SEC/K9 Changes
Rated Performance Written Into the Quotation
500Mbps to 1Gbps published for ISR4431-SEC/K9 as its aggregate throughput, confirmed against the current datasheet revision when the line is quoted.
Uplink Capability Settled at Order Not at Install
4 SFP-based ports on ISR4431-SEC/K9, so the uplink question is answered on the quotation rather than discovered when the unit is already racked.
Powered Access Without a Separate Injector Build
4 Total onboard WAN or LAN 10/100/1000 ports with 250 W with optional redundancy available to powered devices, so access points cameras and phones are fed from the same switch instead of from a parallel power estate.
Support Registered Under the End User Name
A vendor support contract for ISR4431-SEC/K9 is written under the end customer name, so the entitlement sits with the organisation that owns the outage.
Serials Issued Before It Ships
The serial list for your ISR4431-SEC/K9 consignment is released before despatch, so it can be checked on the manufacturer portal while the goods are still with us.
Problems It Solves
Pain Points ISR4431-SEC/K9 Removes
- Performance taken from a family datasheet rather than from this part number, where the published aggregate throughput is 500Mbps to 1Gbps
- Uplink capability fixed at purchase and found insufficient once the access layer behind it was refreshed
- End of sale announcements that leave a proven design with no supply route for ISR4431-SEC/K9
- End of sale announcements that leave a proven branch design with no supply route
- Throughput ceilings reached once encryption and inspection are switched on
Who It Is For
Who Benefits Most From ISR4431-SEC/K9

Branch Network Teams
Rolling out one site design across many locations on a fixed bill of materials
Service Providers
Deploying managed hardware at customer premises with consistent revision and firmware
Education IT
Delivering inside vacation windows against a budget year that rarely aligns with the install date

Use Guide
Deployment Guide for ISR4431-SEC/K9
Confirm the Full Part Number
Check ISR4431-SEC/K9 character for character including any suffix. On this class of hardware a single trailing character commonly changes the software tier, the power option, or whether a bundle is included.
Check Site Prerequisites
Confirm rack space, power feed, cabling and any uplink or accessory dependency before the order rather than on the day of installation.
Calculate the Power Budget
Compare the devices this unit will feed against the 250 W with optional redundancy available, using realistic device draw with headroom rather than class maximums.
Settle the Uplink and Optics
Match the uplink module and transceiver to the platform, the measured span and the fibre already installed, and order them on the same line.
Record It on Arrival
Photograph the sealed carton, reconcile the serial against the list supplied before shipment, then open and confirm the unit matches the label.
Bench Power Before Racking
Power the unit, capture the software version and the port or drive inventory, and record it while the unit is still accessible.

Where It Goes
Industries That Deploy It
Manufacturing and Logistics
Connectivity for plant floors, warehouses and distribution sites built for continuous operation rather than office hours.
Service Provider
Repeatable CPE and aggregation hardware supplied at the volume and consistency a managed service contract depends on.
Solutions
Programmes It Is Supplied Under
Procurement for System Integrators
An integrator carries the risk between quoting a client and receiving the hardware. Firm pricing and a written lead time per line is what makes that risk manageable.
Network Refresh Programme
Most refresh projects fail on supply rather than on design. A phased programme only works if every phase arrives complete on the date the change window was booked.
Support Contracts and SmartNet
A support contract registered under a reseller name is of limited use to the organisation that owns the outage. Entitlement is written under the end user name.
Reference
Project Cases and Guides
Regional Bank Branch Refresh Across 140 Sites
The branch edge had reached end of software support and the estate had drifted into four different router models bought across eight years
Manufacturer Multi Site Network Standard
Each site had bought its own network hardware locally, so no two plants ran the same equipment and no spares could be shared
Network Refresh Planning Checklist
Refresh programmes fail on supply far more often than on design. This is the sequence that keeps a phased rollout on its dates.
Verifying Hardware Authenticity
Checks that cost minutes on arrival and save a great deal later. Most of them can be done before the carton is opened.
New Versus Refurbished Network Hardware
The choice is rarely about quality. It is about entitlement, traceability and what happens eighteen months after the invoice is paid.
FAQ
ISR4431-SEC/K9 Frequently Asked Questions
Is ISR4431-SEC/K9 New or Refurbished
Standard supply is new factory sealed in the original vendor carton. If a quotation offers another condition that is stated explicitly in writing before you commit.
Can I Get the Serial Numbers for ISR4431-SEC/K9 Before Payment Clears
Yes. Serials are issued before shipment so you can check them on the manufacturer portal while the goods are still with us.
What Is the Lead Time for ISR4431-SEC/K9
Availability is confirmed in writing per line at quotation rather than as a project average, because one late line is what moves an installation date.
What Warranty Does ISR4431-SEC/K9 Carry
12 months replacement as standard. A vendor support contract is available separately and is registered under the end user name.
How Much PoE Power Does ISR4431-SEC/K9 Provide
The manufacturer lists maximum endpoint poe power available from poe power supply of 250 W with optional redundancy for this model. A PoE budget should be calculated from realistic device draw with headroom rather than from class maximums.
What Performance Is ISR4431-SEC/K9 Rated For
The published aggregate throughput is 500Mbps to 1Gbps. Full port and performance specifications are issued with the quotation against the current datasheet revision.
Are Uplink Modules and Optics Included With ISR4431-SEC/K9
They are quoted as separate lines and reviewed against the chassis before the quotation is issued, so they reach site in the same consignment as the unit they belong to.
Can You Ship ISR4431-SEC/K9 to My Country
Yes. Consignments go worldwide by courier or freight from Hong Kong, with the routing chosen against the destination clearance regime and your deadline.
Can You Drop Ship ISR4431-SEC/K9 to My Customer
Yes. Consignments can be released directly to an end customer address under your own documentation.
