When 100GE links need inspection, not just forwarding

A 100GE firewall project in Dubai usually starts with a simple question: can the box pass traffic fast enough? That’s only half the story. The real test comes when IPS, application control, antivirus, SSL inspection, web filtering, segmentation, logging, and HA failover all sit in the same design.

The FortiGate 4400F is built for that kind of job. Carrier edge. Large enterprise core. MSSP multi-tenant firewall service. Data centre north-south inspection. It’s not a branch firewall scaled up with bigger ports. It’s a 4 RU FortiGate with 100GE interfaces, high session scale, six NP7 processors, redundant power, and the control paths needed for serious HA work.

For Dubai networks running Etisalat Business or du Enterprise circuits into colocation racks, the buying decision has to look at two numbers side by side: firewall throughput and threat protection throughput. The FortiGate 4400F delivers 1.15 Tbps firewall throughput and 75 Gbps threat protection throughput. That second number is the one security teams should watch when inspection is enabled.

Vector Digital Systems supplies the FortiGate 4400F in Dubai for enterprise, carrier, government, MSSP, and data centre projects. For wider Fortinet sizing, compare this model with the main FortiGate firewall Dubai range before locking the bill of materials.

FortiGate 4400F product overview

The FortiGate 4400F sits in the high-end F-Series range for carrier, ISP, government, and large enterprise environments. It is often specified where 25GE and 100GE links meet heavy segmentation, encrypted traffic, and strict uptime targets. Think of a Dubai data centre edge carrying tenant traffic, internet breakout, inter-site VPN, server farm access, and management zones through the same pair of firewalls.

The appliance gives network architects a large amount of interface choice. There are 12 × 100GE QSFP28 / 40GE QSFP+ slots for core and aggregation links, 16 × 25GE SFP28 / 10GE SFP+ / GE SFP slots for downstream or service connections, 2 dedicated HA slots, 2 AUX slots, and 2 GE RJ45 management ports. Two SFP+ SR 10GE transceivers are included, which helps with first-rack connectivity during staging.

The 4400F and 4401F use the same core platform, but the storage difference matters. The FG-4400F has no onboard SSD. The FG-4401F includes 2 × 1.92 TB SSD storage. For designs where logs are sent to FortiAnalyzer, the FG-4400F may fit. For projects needing local storage on the appliance, the FG-4401F should be checked during the bill of materials stage.

This model is usually bought as an HA pair, not a single standalone firewall. For smaller enterprise sites that don’t need this level of 100GE density, compare down the range with FortiGate 3000F Dubai or FortiGate 2600F Dubai. For carrier and national infrastructure, the 4400F sits in the right conversation.

FortiGuard licensing for FortiGate 4400F

The hardware is the platform. The licence is the protection. Without FortiGuard, the FortiGate 4400F can still work as a stateful firewall, but the security value is reduced. IPS signatures, web filtering categories, antivirus definitions, FortiSandbox Cloud checks, and threat intelligence feeds need an active FortiGuard subscription.

For most Dubai buyers, the decision is between UTP Bundle and Enterprise Bundle. UTP is common where the firewall protects internet breakout, server access, VPN, and general enterprise traffic. Enterprise is better suited to larger teams, OT/industrial networks, MSSPs, and environments where IoT detection, FortiCASB, and FortiConverter services are part of the security plan.

A common mistake is to compare only the FG-4400F hardware price and ignore the licence term. That creates a false saving. For a firewall protecting Etisalat and du WAN links, internet edge traffic, remote access, and east-west server zones, the FortiGuard term is part of the security design, not an optional line at the bottom of the quote.

Vector Digital Systems can quote FortiGate 4400F hardware with UTP or Enterprise licensing in 1-year and 3-year terms. For HA pairs, both appliances need the correct matching subscription term.

FortiGate 4400F specifications

HA and redundancy planning

A FortiGate 4400F project should be designed as an HA pair unless there is a specific lab or non-production reason to use one unit. The platform supports Active-Active, Active-Passive, and clustering, giving architects room to match the firewall design to the routing, switching, and maintenance policy in the data centre.

The 4400F has dedicated HA ports and separate AUX ports, which helps keep failover and sync traffic away from normal production interfaces. That’s important in busy racks where 100GE links carry server, internet, partner, and tenant traffic at the same time. Clean HA cabling saves pain later. Simple point, but it shows up during change windows.

Power and airflow also need early planning. The FortiGate 4400F is a 4 RU appliance with redundant hot-swappable power inputs and front-to-back cooling. In Dubai facilities, where rack density and cooling cost are always part of the design discussion, the firewall should be placed with the same care as core switching and high-density compute gear.

For central logging and reporting, pair the 4400F with FortiAnalyzer sizing that matches traffic volume, retention policy, and compliance needs. Many UAE buyers running this class of firewall also review FortiAnalyzer during the same procurement cycle.

4 RU rackmount firewall for carrier and data centre rooms

The FortiGate 4400F is a 4 RU rackmount firewall, so rack space, airflow, power feeds, transceiver stock, and cable routing should be planned before delivery. This is not a small edge appliance that gets placed wherever there is free space. It belongs in a planned data centre row, carrier room, or enterprise core rack with front-to-back cooling and clear service access.

In Dubai, that usually means colocation racks, telecom rooms, government network cores, or large private data centres where 25GE and 100GE links are already in use. The 4400F fits projects with 10,000+ users, multi-tenant firewalling, MSSP services, high-volume internet edge, large VPN designs, and east-west inspection between server zones.

The front panel gives network teams enough interface density to avoid early add-on complexity: 12 × 100GE QSFP28 / 40GE QSFP+ slots, 16 × 25GE SFP28 / 10GE SFP+ / GE SFP slots, 2 dedicated HA slots, 2 AUX slots, and 2 GE RJ45 management ports. For phased migration, the 100GE ports can support breakout designs where the upstream and downstream fabric still mixes 100GE, 25GE, 10GE, and 1GE links.

For buyers still comparing firewall tiers, review the wider FortiGate firewall Dubai range before choosing between the FortiGate 3000F, 4400F, 4800F, and chassis-class platforms.

Upgrading from FortiGate 3960E or 3980E? Here’s what changes

Many FortiGate 4400F discussions start with an older high-end E-Series firewall reaching refresh stage. The FortiGate 3960E and 3980E were serious appliances in their time, but traffic patterns have changed. More SSL inspection. More east-west segmentation. More cloud backhaul. More 25GE and 100GE switching in the same rack.

The 4400F brings a newer high-end F-Series architecture with six NP7 processors, higher inspected throughput, stronger interface density, and a cleaner path for 100GE aggregation. The headline pair is 1.15 Tbps firewall throughput and 75 Gbps threat protection throughput. That lets the security team talk about inspected traffic honestly, not just raw packet forwarding.

The other change is session scale. Standard concurrent sessions are 210 million, and this can rise to 700 million with the Hyperscale Firewall License. New sessions per second are 1 million standard, rising to 10 million with the same hyperscale licensing. For carrier NAT, high-volume public services, or MSSP tenant traffic, that difference can decide whether the refresh is sized correctly.

When the next refresh cycle arrives, high-end G-Series models may also enter the conversation for sites that want newer SP5 economics. For now, the FortiGate 4400F remains a strong F-Series choice where the project needs field-proven 100GE FortiGate capacity and FortiGuard inspection at high volume.

What’s in the box, and what is not included

A FortiGate 4400F order should be checked by SKU before purchase. The base hardware includes the appliance, redundant power capability, management interfaces, console access, and 2 × SFP+ SR 10GE transceivers. The AC model and DC model are separate variants. The FG-4401F storage variant is also separate.

Transceivers beyond the included 10GE SR pair, 100GE optics, 25GE optics, breakout cables, DAC cables, rack power planning, FortiGuard subscriptions, support terms, and FortiAnalyzer storage are separate items. For 100GE jobs, optics can become a meaningful part of the budget. Better to check them early than delay rack installation later.

For HA pair pricing, both appliances should carry matching FortiGuard UTP or Enterprise subscriptions. Mixing terms across an HA pair creates avoidable renewal and support issues.

Related FortiGate models

Not every data centre needs a 4 RU 100GE firewall. Some projects need to scale down for enterprise edge. Others need to scale up for chassis-based service provider designs. These FortiGate models are worth checking during sizing:

UAE deployment context

In the UAE, the FortiGate 4400F makes sense where downtime has board-level visibility. Carrier links. Payment systems. Government portals. Hotel group networks. Large healthcare platforms. Financial workloads in DIFC. Multi-tenant DMCC environments. This is the class of firewall where HA testing, routing design, and change-window planning matter as much as the hardware quote.

Etisalat and du WAN links can be presented into the 4400F as redundant internet, MPLS, DIA, or private cloud circuits depending on the upstream design. For a busy data centre rack, the firewall pair may sit between internet routers, core switches, server aggregation, VPN services, and security monitoring tools.

Dubai heat and cooling cost also affect the design. The 4400F uses front-to-back airflow and redundant hot-swappable power, so rack location, blanking panels, power feeds, and service clearance should be handled before staging. Sounds basic. It isn’t, once the rack is full.
