In the high-stakes arena of global cybersecurity, Fortinet has long held a formidable position as the king of “convergence.” By blending networking and security into a single, ASIC-powered ecosystem, the company has successfully defended its territory against both massive networking incumbents and agile cloud-native disruptors. As we navigate through 2026, Fortinet’s “Security Fabric” strategy—anchored by its flagship FortiGate firewalls—remains a dominant force, particularly known for offering high performance at a lower Total Cost of Ownership (TCO). However, the landscape is shifting beneath their feet. The market is no longer just about who has the fastest firewall; it is about who can best secure the hybrid workforce, the AI-driven data center, and the cloud edge.
The competitive moat that Fortinet built around its proprietary hardware (SPU/ASIC chips) is being tested by a new wave of threats and competitors. The rise of Secure Access Service Edge (SASE) has moved the battleground from the data center to the cloud, empowering “proxy-based” competitors who argue that hardware is a relic of the past. Simultaneously, the explosion of AI-native threats has emboldened platform players who use vast data lakes and generative AI to predict attacks before they happen—areas where software-first companies claim an inherent advantage over hardware-centric ones.
Today, Fortinet faces a multi-front war. On the high end, it battles premium enterprise guardians like Palo Alto Networks, who sell “trust” and deep visibility over raw throughput. In the mid-market and SMB sectors, it fights a trench war against MSP-friendly vendors like Sophos and SonicWall, who prioritize simplicity over granular control. And in the emerging SASE frontier, it faces pure-play cloud giants like Zscaler. This analysis explores over ten of Fortinet’s fiercest rivals, dissecting their 2025/2026 strategies and illustrating exactly how they are attempting to breach the walls of the Fortinet empire.
Top Competitors of Fortinet
1. Palo Alto Networks
Website – https://www.paloaltonetworks.com/
Palo Alto Networks is widely considered Fortinet’s most sophisticated rival in the enterprise space. While Fortinet competes on “price/performance,” Palo Alto competes on “best-of-breed” security efficacy and platformization. Their strategy revolves around three pillars: Strata (Network Security), Prisma (Cloud Security), and Cortex (Security Operations), aiming to offer a unified, AI-driven security posture for the Fortune 500.
How They Compete with Fortinet
Palo Alto competes through Premium “Platformization” and Layer 7 Visibility.
The “Zero Trust” Argument: Palo Alto Networks often dismisses Fortinet’s throughput-focused marketing. Instead, they emphasize “App-ID” and deep Layer 7 inspection, arguing that raw speed is useless if you can’t see the context of the traffic. They position themselves as the “safer” choice for compliance-heavy industries (finance, healthcare) where granularity matters more than cost.
Cloud-Native SASE: While Fortinet relies on physical firewalls to anchor its SASE offering (FortiSASE), Palo Alto’s Prisma Access is a cloud-native behemoth. They compete by telling CIOs that true SASE shouldn’t rely on backhauling traffic to a hardware appliance, directly attacking Fortinet’s hardware-centric legacy.
AI Leadership: With their “Precision AI” initiatives in 2025, Palo Alto is aggressively marketing their ability to fix security incidents autonomously, challenging Fortinet’s FortiAI capabilities by leveraging a larger data lake from their cloud footprint.
2. Cisco Systems
Website – https://www.cisco.com/
The networking giant remains Fortinet’s primary antagonist in the “networking + security” convergence debate. With its massive install base of switches, routers, and Wi-Fi access points, Cisco effectively owns the infrastructure of millions of businesses. Following its strategic acquisitions (like Splunk), Cisco is trying to reclaim the security crown by leveraging data observability.
How They Compete with Fortinet
Cisco competes through Infrastructure Lock-in and Observability.
The Ecosystem Bundle: Cisco’s primary weapon is the Enterprise Agreement (EA). They compete with Fortinet by bundling security (Cisco Secure Firewall, Umbrella, Duo) with massive networking deals. If a company is already refreshing its Catalyst switches, Cisco can make the security layer appear “practically free,” undercutting Fortinet’s value pricing.
Splunk-Powered Security: The integration of Splunk has given Cisco a massive advantage in SIEM and observability. They now compete against FortiSIEM and FortiAnalyzer by offering a data platform that spans the entire IT stack, not just security logs. They argue that Fortinet offers “siloed” security visibility, whereas Cisco + Splunk offers “whole business” visibility.
3. Check Point Software Technologies
Website – https://www.checkpoint.com/
Check Point is the “grandfather” of the modern firewall and remains a stalwart in the high-security enterprise market. Known for its “Infinity” architecture, Check Point focuses heavily on prevention rather than just detection.
How They Compete with Fortinet
Check Point competes on Security Efficacy and “Prevention-First” Methodology.
The “Quality over Speed” Pitch: Check Point attacks Fortinet’s reliance on ASIC chips. They argue that hardware acceleration often forces vendors to cut corners on inspection depth to maintain high speeds (e.g., using “flow-based” inspection vs. Check Point’s deeper inspection). They position themselves as the vendor for customers who cannot afford a single breach, regardless of the price premium.
Maestro Hyperscale: To counter Fortinet’s performance claims, Check Point utilizes its Maestro orchestration, which allows companies to stack multiple gateways to act as one massive system. This competes directly with Fortinet’s high-end chassis firewalls by offering scalability through software orchestration rather than just bigger hardware boxes.
4. CrowdStrike
Website – https://www.crowdstrike.com/
CrowdStrike started as an endpoint company but has morphed into a platform giant. Its Falcon platform is the gold standard for EDR (Endpoint Detection and Response) and XDR (Extended Detection and Response).
How They Compete with Fortinet
CrowdStrike competes via The “Endpoint-to-Cloud” Shift.
Rendering the Firewall Less Relevant: CrowdStrike’s philosophy is that the network perimeter is dissolving. By placing a lightweight agent on every laptop and server (Falcon Sensor), they argue they have better visibility than a FortiGate firewall sitting at the network edge. They compete for the CISO’s budget by arguing that identity and endpoint protection are the new perimeter, attempting to siphon budget away from network firewalls.
Falcon vs. FortiClient: In the XDR space, CrowdStrike is the heavyweight champion. They compete against Fortinet’s FortiClient/FortiEDR by offering a more mature, AI-native threat hunting service (OverWatch) that appeals to enterprises lacking a full SOC team.
5. Zscaler
Website – https://www.zscaler.com/
Zscaler is the pioneer of the “Zero Trust Exchange.” They do not sell boxes; they sell a cloud service that connects users to apps. They are the antithesis of Fortinet’s “firewall everywhere” strategy.
How They Compete with Fortinet
Zscaler competes on Architecture: Proxy vs. Firewall.
The “No Hardware” Crusade: Zscaler competes by attacking the very existence of the VPN and the firewall. They tell customers that Fortinet’s approach (using firewalls for SASE) creates “attack surfaces” because the devices listen on the public internet. Zscaler’s architecture makes the network invisible, offering a compelling security argument for cloud-first organizations.
SSE Dominance: In the Security Service Edge (SSE) market (the security half of SASE), Zscaler is often seen as the market leader. They compete with FortiSASE by offering a larger global point-of-presence (PoP) footprint, ensuring lower latency for remote users without relying on on-premise appliances.
6. HPE Aruba Networking (incorporating Juniper Networks)
Website – https://www.hpe.com/us/en/networking/hpe-aruba-networking.html
With Hewlett Packard Enterprise’s acquisition of Juniper Networks, a new networking super-power has emerged. The combination of Aruba’s dominance in the campus (Wi-Fi/LAN) and Juniper’s Mist AI creates a massive threat to Fortinet’s “Secure Networking” story.
How They Compete with Fortinet
They compete through AI-Native Networking and Campus Experience.
Mist AI vs. FortiAIOps: The combined entity leads the market in “AIOps.” They compete by offering a user experience (Mist) that uses AI to fix Wi-Fi and switching issues automatically. They argue that Fortinet’s “Security Fabric” is great for locking things down but clunky for managing user experience (e.g., “Why is the Wi-Fi slow?”).
SD-WAN Leadership: HPE Aruba’s EdgeConnect (formerly Silver Peak) is a top-tier SD-WAN platform. They compete with FortiGate SD-WAN by focusing on “WAN optimization” and superior quality of experience for voice/video, rather than just security-led routing.
7. Sophos
Website – https://www.sophos.com/en-gb
Sophos is a UK-based cybersecurity company that has found massive success in the Managed Service Provider (MSP) channel. Their “Synchronized Security” strategy links their endpoints and firewalls to talk to each other.
How They Compete with Fortinet
Sophos competes via Simplicity and MSP-First Strategy.
The “Heartbeat” Link: Sophos’s killer feature is the communication between its endpoint (Intercept X) and firewall (XGS). If a laptop gets infected, the firewall automatically isolates it. While Fortinet has similar capabilities, Sophos markets this as a “zero-touch” automated solution specifically for SMBs who don’t have a security team to write complex automation scripts.
MDR for the Masses: Sophos has aggressively pivoted to selling MDR (Managed Detection and Response) as a service. They compete with Fortinet by selling the service of security (humans watching screens) rather than just the tools. For mid-sized companies, hiring Sophos MDR is often cheaper/easier than buying Fortinet gear and hiring staff to run it.
8. SonicWall
Website – https://www.sonicwall.com/
SonicWall is a veteran in the firewall space, traditionally strong in the Small and Medium Business (SMB) market. After separating from Dell and refreshing its portfolio (Gen 7 Firewalls), it remains a “value” competitor.
How They Compete with Fortinet
SonicWall competes on Price-Performance for SMBs.
The “Good Enough” Value Play: In the trench warfare of small business IT (retail chains, small offices), SonicWall competes aggressively on price. They often position their “TotalSecure” bundles as a simpler, lower-cost alternative to Fortinet, specifically targeting customers who find Fortinet’s feature set overkill and its licensing complex.
MSSP Loyalty: SonicWall has a fiercely loyal base of smaller Managed Security Service Providers. They compete by offering flexible monthly billing models that align better with how small MSPs sell to their clients, an area where Fortinet’s enterprise-grade licensing can sometimes be rigid.
9. Microsoft (Azure & Defender)
Website – https://azure.microsoft.com/en-us/explore/security
Microsoft is the “sleeping giant” that has fully awakened. With its massive cloud footprint and the omnipresent Windows/Office ecosystem, Microsoft is increasingly becoming a “single vendor” security shop for many CIOs.
How They Compete with Fortinet
Microsoft competes via Consolidation and “Free” Inclusion.
Azure Firewall vs. FortiGate VM: For companies moving workloads to Azure, Microsoft pushes its native Azure Firewall. They compete by offering “one-click” deployment and native integration. They argue, “Why manage a third-party FortiGate virtual machine when Azure Firewall is built into the platform?”
Defender vs. FortiClient: Microsoft Defender for Endpoint is now included in many E5 licenses. This effectively kills the market for third-party endpoint agents like FortiClient in Windows-heavy environments, as IT directors struggle to justify paying for an extra agent that duplicates what Microsoft provides “for free.”
10. WatchGuard Technologies
Website – https://www.watchguard.com/
WatchGuard is a Seattle-based security vendor that focuses almost exclusively on the mid-market and distributed enterprises. They are known for their distinctive red boxes and strong focus on “Unified Security.”
How They Compete with Fortinet
WatchGuard competes on Ease of Management and “Unified Security Platform”.
Visualizing the Threat: WatchGuard’s “Dimension” visibility tool is a key selling point. They compete by making security data easy to understand for generalist IT managers, contrasting with the dense, technical interface of FortiOS.
MFA Integration: WatchGuard acquired AuthPoint (Multi-Factor Authentication) and integrates it deeply into their firewall. They compete with Fortinet by offering a simple, out-of-the-box MFA solution for VPNs and logins that doesn’t require the complexity of setting up FortiAuthenticator or FortiToken for smaller deployments.
11. Barracuda Networks
Website – https://www.barracuda.com/
Barracuda is a cloud-first security company known for its email protection, but its CloudGen Firewall is a robust competitor in specific verticals like industrial IoT and hybrid cloud.
How They Compete with Fortinet
Barracuda competes via Industrial IoT and Public Cloud Affinity.
Operational Technology (OT) Niche: While Fortinet is strong in OT, Barracuda competes heavily in distributed industrial environments (like wind farms or gas stations) with ruggedized appliances that are exceptionally easy to deploy via zero-touch provisioning.
Azure vWAN Integration: Barracuda was one of the first to tightly integrate with Azure’s Virtual WAN. They compete by being the “easy button” for Azure networking, often winning deals where the customer’s primary infrastructure is heavily invested in the Microsoft cloud.
12. Trend Micro
Website – https://www.trendmicro.com/
A global leader in hybrid cloud security, Trend Micro (via its Vision One platform) competes with Fortinet in securing data centers and cloud workloads.
How They Compete with Fortinet
Trend Micro competes on Virtual Patching and Hybrid Cloud Workload Security.
Shielding the Unpatchable: Trend Micro’s “Deep Security” is famous for virtual patching—protecting legacy servers that can’t be updated. They compete with Fortinet’s IPS by offering a host-based solution that travels with the workload, regardless of network boundaries.
XDR for the Data Center: Trend Micro is historically stronger in server security than Fortinet. They compete by offering a platform that understands the nuances of Linux and container environments better than a network-centric vendor, winning the hearts of DevOps teams over Network Admin teams.

Conclusion
In 2026, Fortinet remains a juggernaut, bolstered by its proprietary ASIC technology that allows it to offer unmatched price-to-performance ratios. However, the definition of “performance” is evolving. While Fortinet wins on Throughput (Gbps per dollar), competitors like Palo Alto Networks and Zscaler are winning on Transformation (shifting to the cloud). Meanwhile, CrowdStrike is winning on Telemetry (endpoint data), and Cisco and HPE are leveraging their massive Infrastructure gravity.
For Fortinet to maintain its dominance, it must successfully pivot its massive install base to its new “Unified SASE” and “SecOps” platforms. The competitors listed above are not just selling better firewalls; they are selling a future where the firewall may no longer be the center of the universe. The battle for the next decade will not be fought in the rack, but in the cloud, the endpoint, and the AI model.
