Fortinet Firewalls in Pakistan: The G Series Guide for Q3 2026

Fortinet Firewalls in Pakistan: The G Series Guide for Q3 2026

If you are evaluating a Fortinet firewall in Pakistan right now, the G Series is what you should be looking at. Fortinet has been transitioning its lineup away from the F Series, and the G Series is the current generation across the board. Every Fortinet firewall in this range runs on FortiOS with the same feature set regardless of which model you pick, scales from a small branch office to a large campus or data centre edge, and uses Fortinet’s purpose-built FortiASIC processors to deliver security performance without the throughput penalty that software-based inspection creates. This guide covers all eight models you need to know about: 50G, 70G, 90G, 120G, 121G, 200G, 401G, and 700G, what each one is built for, what the specs actually mean in practice, and how to choose the right platform for your environment. One important note before the specs: every throughput figure quoted by Fortinet is a lab maximum under ideal conditions. Real-world numbers with full security profiles enabled, meaning IPS, antivirus, application control, and SSL inspection all running simultaneously, will be lower. The threat protection throughput figure is the honest one to plan around. The firewall throughput number is what you get when most security features are off. What Makes the G Series Different The G Series is built on Fortinet’s latest FortiASIC architecture. Rather than running all security functions on a general-purpose CPU, which creates throughput bottlenecks when inspection gets heavy, the G Series offloads different tasks to dedicated processors. The SoC5, used in the smaller desktop models, integrates multiple processing functions onto a single chip. The SP5 handles deep packet inspection, SSL/TLS decryption, and IPS at line rate. The NP7 accelerates packet forwarding and IPsec VPN encryption. The result is that turning on full inspection does not cut your throughput to a fraction of what the headline spec suggests, which is the experience many organisations have with software-based or older hardware firewalls. All G Series models include Secure SD-WAN, ZTNA enforcement, and FortiGuard threat intelligence support as standard features of FortiOS. None of these require a separate license for the core functionality. FortiGuard security services, covering IPS, antivirus, web filtering, and application control, require a subscription, but the platform itself is fully featured out of the box. The Models: Specs and Who Each One Is For

FortiGate 50G

Form factor: Desktop Firewall throughput: 4 Gbps Threat protection throughput: 500 Mbps SSL inspection throughput: 400 Mbps Concurrent sessions: 700,000 Recommended users: Up to 25 The 50G is the entry point for businesses that have outgrown consumer-grade routers but do not need rack-mounted hardware. It is a compact desktop unit with built-in Wi-Fi options and LTE failover support, making it a practical choice for a small branch office, a retail outlet, or a professional services firm with a single location. The 500 Mbps threat protection figure is what matters here. If your internet connection is 200 Mbps or less and you are running a small team, the 50G handles that load comfortably with all security features on. If you are on a faster link or running more than 25 users, move up.

FortiGate 70G

Form factor: Desktop Firewall throughput: 5 Gbps Threat protection throughput: 1.1 Gbps SSL inspection throughput: 1.3 Gbps Concurrent sessions: 1 million Recommended users: 25 to 50 The 70G is one of the most commonly deployed branch models in the G Series, and for good reason. It offers a meaningful step up from the 50G in threat protection throughput, handles more concurrent sessions, and includes PoE support on the hardware variants for powering access points and phones from the same device. For a Karachi SME with a single office running 30 to 50 people on a fibre connection, the 70G is usually the right answer. The 1.1 Gbps threat protection throughput handles a 500 Mbps to 1 Gbps internet link with all inspection features running. Businesses that try to save budget by sizing down to the 50G and then enabling full inspection often find themselves at the ceiling sooner than expected.

FortiGate 90G

Form factor: Desktop Firewall throughput: 10 Gbps Threat protection throughput: 1.3 Gbps SSL inspection throughput: 1.4 Gbps Concurrent sessions: 3 million Recommended users: 50 to 100 The 90G adds SFP ports for fibre connectivity, which matters for businesses connecting to fibre uplinks directly or running structured cabling rather than copper. The jump to 3 million concurrent sessions is significant for environments with a large number of simultaneous connections, such as offices running cloud applications across multiple browser tabs for every user. For larger branches, SD-Branch hub locations, or manufacturing facilities in Karachi’s industrial zones where multiple devices and OT systems are all terminating on the same firewall, the 90G provides the session capacity and throughput headroom to handle that load without degrading performance. FortiGate 120G Form factor: 1U rackmount Firewall throughput: 39 Gbps Threat protection throughput: 2.8 Gbps SSL inspection throughput: 3 Gbps Concurrent sessions: 3 million Recommended users: 100 to 250 The 120G is where the G Series moves from desktop to rack. It is a 1U appliance with 16 Gigabit RJ45 switch ports, eight Gigabit SFP slots, and four 10GE SFP+ FortiLink slots, making it significantly denser than the desktop models. Dual built-in power supplies come standard, adding resilience that desktop units do not offer. The 2.8 Gbps threat protection throughput makes this the right platform for a growing business that has a 1 Gbps or faster internet link, multiple VLANs, and enough complexity in the network that a desktop appliance would struggle to manage cleanly. Financial services firms, mid-sized manufacturers, and education institutions in Pakistan running active user bases of 100 to 250 are the natural fit here. FortiGate 121G Form factor: 1U rackmount Firewall throughput: 39 Gbps Threat protection throughput: 2.8 Gbps SSL inspection throughput: 3 Gbps Concurrent sessions: 3 million Recommended users: 100 to 250 The 121G is identical to the 120G in every meaningful specification. Same chassis, same ports, same throughput. The single difference is a 480 GB onboard SSD for local logging and reporting. If your organisation needs logs available on the device itself, whether for compliance, forensic purposes, or because you do not have a FortiAnalyzer or cloud logging setup, the 121G is the model to specify. If you are centralising logs off-box, the 120G saves you money with no functional difference. For Pakistani organisations operating under SBP, SECP, or PTA compliance requirements that specify on-premises log retention, the 121G resolves that requirement at the hardware level without additional infrastructure. FortiGate 200G Form factor: 1U rackmount Firewall throughput: 39 Gbps Threat protection throughput: 6 Gbps SSL inspection throughput: 7 Gbps Concurrent sessions: 11 million Recommended users: 250 to 500 The 200G is where the G Series starts serving large campus environments. The jump from 2.8 Gbps to 6 Gbps threat protection and from 3 million to 11 million concurrent sessions reflects a meaningfully different class of deployment. Multi-gigabit ports support modern high-speed switches and access points without the bandwidth becoming the limiting factor. For corporate headquarters in Karachi’s commercial districts, regional offices with dense user populations, or organisations doing significant internal traffic segmentation across VLANs, the 200G handles that complexity at scale. It is also the crossover point between mid-range and enterprise in the G Series, making it a natural anchor for networks that expect to grow. FortiGate 401G Form factor: 1U rackmount Firewall throughput: 198 Gbps Threat protection throughput: 22 Gbps SSL inspection throughput: 22 Gbps Concurrent sessions: 16 million Recommended users: 500 and above The 401G is the 400G with a 960 GB onboard SSD added. The 400G is a high-performance campus and data centre edge platform. At 22 Gbps threat protection throughput and 16 million concurrent sessions, it is handling traffic volumes that are well beyond what most businesses in Pakistan will ever generate internally. The port layout includes 4x 25G SFP28, 4x 10GE SFP+, 16x 1G SFP, and 8x 5G BASE-T RJ45, covering every connectivity requirement a large enterprise network is likely to present. The distinction between the 400G and 401G is the same as between the 120G and 121G: the 401G keeps its logs on-device. For large enterprises, telecoms, or financial institutions in Pakistan that need high availability, dense connectivity, and local log retention under a single appliance, the 401G is the platform to specify. FortiGate 700G Form factor: 2U rackmount Firewall throughput: 200 Gbps Threat protection throughput: 26 Gbps SSL inspection throughput: 26 Gbps Concurrent sessions: 16 million Recommended users: 500 and above, high-traffic environments The 700G sits above the 401G in the G Series and is built for high-performance environments where 25GE uplinks are required and traffic volumes are substantial. With 26 Gbps threat protection and native 25GE connectivity, it is the right platform for large enterprise data centre edges, high-traffic campus cores, and organisations running significant east-west traffic that all needs to be inspected. In the Pakistan context, the 700G is relevant for large telecoms, major financial institutions, and data centre operators. It is not the right conversation for most businesses, but for organisations that have outgrown the 400G class and need to scale without moving to a chassis-based system, the 700G provides the headroom.

Choosing the Right Model for Your Environment

The most common sizing mistake is buying on firewall throughput rather than threat protection throughput. A 90G advertises 10 Gbps firewall throughput. Enable IPS, antivirus, web filtering, and SSL inspection simultaneously and you are working with 1.3 Gbps. If your internet connection is 1 Gbps and your team is 80 people all running cloud applications, you need the 120G, not the 90G. SSL inspection deserves its own attention. Over 90% of internet traffic is HTTPS-encrypted. A firewall that cannot inspect encrypted traffic has no visibility into the majority of what is entering and leaving your network. The SSL inspection throughput figure tells you what the device can actually handle when it is doing the work that modern threat detection requires. For most Pakistani SMEs, the Fortinet firewall sizing guide is straightforward. Under 50 users on a connection up to 500 Mbps, the 70G. Fifty to 100 users or a faster link, the 90G. A growing business moving to a rack environment with 100 to 250 users, the 120G or 121G depending on logging requirements. Beyond that, the 200G and above serve larger enterprises and organisations with more complex requirements. If you are between two models, choose the larger one. Security headroom is not wasted.
