Fortinet Alternatives for Business Networking & NaaS

Fortinet Alternatives for Business Networking and NaaS

If you are evaluating Fortinet alternatives, you are likely weighing whether a security-first, self-run platform still fits, or whether you want networking-first simplicity, a fully-managed service, or a different security architecture. This page routes IT and procurement teams to the providers worth a closer look, summarizes where each fits, and links to full reviews so you can compare fairly before you request quotes.

Fortinet alternatives, side by side

Here is how the main Fortinet alternatives compare on model, strengths, and the honest trade-offs that matter when you move away from a Security Fabric approach.

Option	Best fit	Strengths	Watchouts	When to consider it
Nile	Security-led, regulated, US-primary	Zero-trust segmentation built into the fabric; fully managed; performance SLAs on the Advanced tier	US-primary coverage; less hands-on engineer control; no hardware buyback	You want a strong security posture but delivered as a managed service instead of a platform you run
Meter	Lean IT, CapEx-averse, multi-site	Fully managed NaaS; provider owns the hardware so no CapEx; ISP often bundled; hardware buyback	Advanced security such as NGFW and ZTNA comes via adjacent tools; less engineer-level control; newer vendor	You want to stop operating the network and firewall stack yourself and move to a per-square-foot managed model
Cisco Meraki	Self-managed, global, easy hiring	Cloud-managed dashboard; deep global ecosystem; dashboard skills easy to hire; broad security add-ons	Hardware CapEx plus per-device licensing; your team or a partner operates it; features tied to active licenses	You want to keep operating the network but trade the Security Fabric for a simpler, more familiar dashboard
HPE Aruba	Large enterprise campus	Strong campus Wi-Fi; Aruba Central AIOps; Aruba ESP zero trust; NaaS path via HPE GreenLake consumption	Enterprise scale and complexity; run by your engineers or a partner; consumption model needs sizing	You are a large campus or existing HPE estate wanting a NaaS consumption option with built-in zero trust
Juniper Mist	Complex enterprise with engineers	AI-driven operations via Marvis AIOps; cloud-managed; suited to large, complex environments	Hardware plus per-device cloud subscriptions; run by your engineers or a partner; not a fully-managed service	You want to keep in-house control and add AIOps rather than move to a managed or security-first platform
Ubiquiti UniFi	Cost-sensitive, in-house skills, simpler sites	Lower-cost hardware; free self-hosted controller; no recurring license fees	Not a managed service; no SLA or managed support; you design, deploy, secure, and support it yourself	You want to cut recurring license spend and have the in-house skills to run networking and security yourself

Why buyers compare alternatives

Renewal cost

Fortinet cost tracks your FortiCare support and FortiGuard security license tiers on top of the hardware you purchased. At renewal, review whether those recurring tiers still match how you use the platform, and compare that total against subscription or consumption models where hardware and licensing are bundled into one fee.

Support model

With Fortinet you or an MSSP operate the Security Fabric day to day. If your team is spending its time tuning policy and managing SKUs rather than on the business, a fully-managed alternative can shift that operational load to the provider. If you value hands-on control, keeping a self-run model may still be the right call.

Hardware refresh timing

Fortinet hardware is purchased as CapEx, so a refresh cycle is a natural moment to reconsider the model. Some alternatives include the hardware in the subscription and handle refresh for you, which changes both the accounting and the timing of your next capital request.

Multi-site complexity

Fortinet's secure SD-WAN is a genuine strength across distributed sites, but it also multiplies the licenses and policy you manage. Weigh whether a fabric that unifies security across every location is worth the operational overhead, or whether a per-site managed model would be simpler to scale.

Security requirements

Fortinet leads with security, so any alternative has to be judged on how it handles firewalling, segmentation, and zero trust. Some providers build zero-trust segmentation into the network fabric itself, while others deliver advanced security through adjacent tools you add on. Match the architecture to your compliance and threat model.

Internal IT bandwidth

Running Fortinet well requires skilled engineers or an MSSP. Be honest about the bandwidth and expertise you have in-house. If staffing is thin, a fully-managed NaaS offloads design, deployment, and support; if you have strong engineers, an AIOps or cloud-managed platform may keep them productive.

Vendor lock-in

The Security Fabric's value comes from keeping firewall, switching, Wi-Fi, and SD-WAN under one vendor, which also deepens lock-in. Consider how hard it would be to unwind that stack, and whether a more modular or managed alternative gives you a cleaner exit and clearer contract terms at your next renewal.

Best alternatives by buyer type

If you are a...	Worth a close look	Why
Multi-site business	Meter	A fully-managed, per-square-foot model scales cleanly across growing locations without adding CapEx or per-site license management. It suits distributed teams that want consistent delivery without operating Fortinet's SD-WAN and license stack themselves.
Lean IT team	Meter	Fortinet asks your team to run the Security Fabric and juggle FortiCare and FortiGuard tiers. A fully-managed NaaS that owns the hardware and handles operations frees a small IT team from the day-to-day platform work.
Security-led organization	Nile	For teams that chose Fortinet for security posture, Nile builds zero-trust segmentation directly into the fabric and delivers it as a managed service, keeping a strong security architecture without you operating the stack. The trade-off is US-primary coverage and less hands-on control.
Enterprise campus	HPE Aruba	Large campuses get strong Wi-Fi, Aruba Central AIOps, and ESP zero trust, with a NaaS consumption path through HPE GreenLake. It fits enterprises and existing HPE estates weighing a Fortinet alternative at scale, though your engineers or a partner still operate it.
Budget-conscious business	Ubiquiti UniFi	If cutting recurring spend is the priority and you have in-house skills for simpler sites, UniFi's lower-cost hardware and free self-hosted controller avoid license fees entirely. The trade-off is that it is not a managed service, so there is no SLA and you own design, security, and support yourself.
Regulated industry	Nile	Regulated buyers that need built-in segmentation and documented service levels get zero trust in the fabric plus performance SLAs on the Advanced tier, delivered as a managed service rather than a platform your team must secure and prove. Confirm its US-primary coverage matches your sites.

These are starting points, not verdicts. The right fit depends on your footprint, team, and security needs. An independent evaluation framework walks through it.

Pricing and contract considerations

Fortinet cost combines hardware purchased as CapEx with FortiCare and FortiGuard license tiers, so totals depend on the appliances, services, and tiers you select. Alternatives price differently: fully-managed NaaS is often billed per square foot or per user, cloud-managed platforms add per-device licensing on top of hardware, and consumption models bill on usage.

Because pricing depends on your number of locations, square footage, users, access points, service level, security requirements, implementation scope, and contract term, published list prices rarely reflect what you will pay. Compare quotes on the same scope and term to make the numbers meaningful.

The fastest way to a realistic range is to run your own numbers, then compare it against real quotes. Try the NaaS pricing calculator, and see the full NaaS pricing guide for how the models and cost drivers work.

Migration and evaluation checklist

Run every provider on your shortlist, including Fortinet, through the same questions and write the answers down. Vague answers are data too.

What is our true all-in Fortinet cost today, including hardware amortization plus every FortiCare and FortiGuard license tier we renew?

Which security functions are we actually using (firewall, SD-WAN, ZTNA, threat filtering), and which does each alternative match natively versus through add-on tools?

Do we want to keep operating the platform ourselves, or shift design, deployment, and support to a managed provider?

If we move to a managed or subscription model, is the hardware owned by the provider, and is there a buyback or refresh included?

How will multi-site policy and segmentation be handled without the Security Fabric unifying every location under one stack?

What are the coverage limits of each alternative, and do they match every region and site we operate in?

What compliance and audit evidence do we need, and can the alternative document zero trust and service levels the way we require?

What contract term, renewal terms, and exit terms apply, and how do they compare to our current Fortinet commitment?

How disruptive is the cutover, and can it be phased site by site to limit risk to production traffic and security posture?

Do we have the in-house engineering bandwidth to run the alternative, or are we explicitly buying our way out of that with a managed model?

How does each option handle firewalling and perimeter security, since that is the capability Fortinet is built around and the one we cannot regress on?

What does an apples-to-apples quote look like across two or three alternatives on identical scope and term?

Fortinet alternatives, answered

The right Fortinet alternative depends on why you are leaving. For a security-led managed service, look at Nile with its built-in zero-trust fabric. For a fully-managed, no-CapEx model, look at Meter. To keep self-managing with a simpler dashboard, consider Cisco Meraki. For enterprise campus scale with a NaaS path, HPE Aruba fits; for AIOps under your own engineers, Juniper Mist; and for the lowest recurring cost with in-house skills, Ubiquiti UniFi.

Nile is a strong fit if you chose Fortinet for security but want it delivered as a service. Nile builds zero-trust segmentation into the network fabric and offers performance SLAs on its Advanced tier, all fully managed. The main trade-offs are US-primary coverage, less hands-on engineer control, and no hardware buyback.

Meter fits teams that want to stop operating the network and firewall stack themselves. It is a fully-managed NaaS where the provider owns the hardware, so there is no CapEx, and ISP is often bundled. The trade-off is that advanced security such as NGFW and ZTNA comes through adjacent tools rather than a single security fabric, and Meter is a newer vendor.

Start with your true all-in cost (hardware plus every FortiCare and FortiGuard tier), then map which security functions you actually use so you can match them in an alternative. Decide whether you want to keep self-managing or move to a managed model, plan multi-site segmentation without the Security Fabric, and confirm coverage, compliance evidence, and contract exit terms before committing.

Meter and Nile are delivered as fully-managed services, so the provider handles design, deployment, and ongoing operations rather than your team or an MSSP. Cisco Meraki, HPE Aruba, and Juniper Mist are cloud-managed or AIOps platforms that you or a partner still operate, though HPE Aruba offers a NaaS consumption path through HPE GreenLake. Ubiquiti UniFi is self-managed with no managed support.

Yes. Meter owns the hardware as part of its managed subscription, so there is no CapEx, and it offers a hardware buyback. HPE Aruba can bundle hardware into a GreenLake consumption model. By contrast Cisco Meraki and Juniper Mist keep hardware as a purchase with separate per-device licensing, similar in structure to Fortinet.

Often yes. A common architecture keeps a FortiGate firewall at the perimeter for security, SD-WAN policy, and threat filtering while a managed provider handles switching and Wi-Fi. That lets you retain Fortinet's security strength while offloading the network layer, and an advisor can help design and quote the combination.
