Peplink vs Cradlepoint vs Fortinet: choosing a cellular SD-WAN platform

The SD-WAN cellular vendor landscape

Three vendors dominate the cellular-capable SD-WAN market for enterprise, public safety, and mobile use cases: Peplink, Cradlepoint (now part of HP), and Fortinet (with cellular-equipped FortiGate variants). Several other players (Sierra Wireless/Semtech, Digi, Inseego, MikroTik) operate in adjacent niches but the three big choices for serious cellular SD-WAN deployments come down to those three.

The vendors target meaningfully different customer profiles. Peplink originated in multi-WAN bonding for broadcast, maritime, and remote enterprise. Cradlepoint originated in US-centric mobile and branch cellular WAN with deep MNO partnerships. Fortinet originated in network security (FortiGate firewalls) and extended into SD-WAN with cellular as a WAN option on existing security hardware. The historical origin still shapes each vendor's strengths today.

Quick-reference comparison

Where Peplink wins

Multi-WAN bonding depth

SpeedFusion is Peplink's proprietary multi-WAN bonding technology. Unlike session-level bonding (where one session goes down one path), SpeedFusion operates at the packet level: the same packet is sent down multiple paths simultaneously, the receiving end accepts whichever copy arrives first, and discards duplicates. The result is that brief outages on any single link become invisible to the application layer. For workloads where sub-second packet loss is destructive (live broadcast contribution, VoIP, video calls, vessel telemetry), SpeedFusion delivers reliability that session-level bonding simply can't match.

Cradlepoint and Fortinet both offer cellular SD-WAN with multi-modem failover. Neither matches the depth of SpeedFusion's packet-level bonding modes (Hot Failover, WAN Smoothing, Bandwidth Bonding, all selectable per traffic class). For most enterprise SD-WAN, session-level failover is sufficient. For broadcast and maritime, it isn't.

Modular hardware (FlexModule)

Peplink's Balance SDX takes 2 FlexModule Plus expansion modules. The EPX-M8 takes 8. Modules cover cellular (2x 5G, 2x LTEA Cat-20, 4x LTEA Cat-12), fibre (4x SFP+), Ethernet (8x GE PoE), and centralised SIM management. A single SDX or EPX chassis can be configured as cellular-heavy, fibre-heavy, or any mix; modules are hot-swappable. Smaller routers like the Balance 580X HW2 take FlexModule Mini for tiered cellular expansion.

Cradlepoint and Fortinet hardware is mostly fixed-configuration. You buy the model with the cellular and Ethernet count you need, and that's the chassis. For deployments where the WAN edge architecture changes over the hardware lifecycle (e.g. SDX deployed with cellular today, fibre added in year 3), Peplink's modularity is meaningful. For fixed deployments that won't change, the modularity is a non-feature.

Maritime, broadcast, and specialty mobile

Peplink's hardware portfolio includes IP67-rated marine antennas (Antenna MAX, Antenna MAX Duo), maritime mast adapters (ACW-651, ACW-653A), through-deck cable gland kits (ACW-420), and outdoor-rated dual-cellular dome routers (Dome Pro Duo 5G). For broadcast contribution, the HD2 MBX 5G and Transit Duo Pro are purpose-built for OB vehicles and live event production.

Cradlepoint and Fortinet are primarily branch and mobile vehicle plays. They don't compete in maritime hardware to the same depth. If your deployment is vessel, OB van, ENG kit, or outdoor-mast cellular, Peplink is the natural choice; the alternatives don't have equivalent hardware.

Where Cradlepoint wins

US carrier integration and FirstNet

Cradlepoint has historically deep partnerships with US mobile network operators, particularly AT&T (which operates FirstNet, the US public safety LTE network). Cradlepoint hardware is broadly certified for FirstNet Band 14 and is the default cellular SD-WAN choice for US public safety procurement. NetCloud Manager has carrier-side optimisation features for AT&T, T-Mobile, and Verizon that aren't replicated outside the US.

Peplink is also FirstNet-certified on several models, but Cradlepoint's depth in US public safety is significantly greater. For US patrol fleets specifically, Cradlepoint is a credible default. For UK and European public safety (ESN, post-Airwave operations), the carrier-integration advantage doesn't apply equally; Peplink is more widely deployed.

Simplified mobile fleet deployment

Cradlepoint's mobile product line is narrower than Peplink's, which makes spec selection simpler. Where Peplink has BR1 Mini, BR1 Pro 5G, BR1 IP67, BR2 LTE, BR2 Pro 5G, Transit Pro E, Transit Duo Pro, HD2, HD2 MBX, HD4 MBX (and that's just mobile), Cradlepoint's mobile portfolio is more focused. For procurement teams that value SKU simplicity over feature depth, Cradlepoint is easier to standardise across a fleet.

Enterprise mobility cloud bundling

NetCloud Manager bundles cloud management, security services, and carrier connectivity in subscription tiers that some buyers prefer to Peplink's separated PrimeCare hardware service plus carrier SIM model. For organisations that want one vendor invoice covering everything, Cradlepoint's bundling is operationally simpler.

Where Fortinet wins

Existing FortiGate estate extension

If your organisation already runs FortiGate firewalls across hundreds of branches, extending the same operational model to cellular WAN via cellular-capable FortiGate hardware is straightforward. Single management plane (FortiManager), single security policy (FortiOS), single threat intelligence subscription (FortiGuard). The integration is Fortinet's structural advantage over standalone cellular SD-WAN vendors.

Integrated edge security (UTM)

Fortinet's strength is the full Unified Threat Management stack: stateful firewall, IPS, web filtering, anti-malware, application control, SSL inspection, all native to the platform. Peplink hardware has a credible integrated firewall but doesn't ship the full UTM stack natively. For security-led deployments where the edge router's primary job is threat prevention and SD-WAN is secondary, Fortinet's depth is meaningful.

SASE positioning

Fortinet has invested heavily in Secure Access Service Edge (SASE) architecture: cloud-based security services delivered to remote and mobile users. For organisations adopting SASE as their security architecture, Fortinet's integrated platform fits naturally. Peplink and Cradlepoint participate in SASE adjacent ways but aren't SASE-native.

Decision framework

Pick based on the dominant use case. The decision isn't usually "which vendor is best" but "which vendor matches what we're actually doing".

Pick Peplink if

• Your deployment is maritime, broadcast contribution, OB vehicle, or specialty mobile where multi-cellular bonding and rugged outdoor hardware are the requirements.
• You need packet-level bonding (SpeedFusion) for loss-sensitive workloads (live video, VoIP, telemetry).
• You want hardware modularity (FlexModule) for SD-WAN deployments where the WAN edge architecture will evolve over the hardware lifecycle.
• You're outside the US and the FirstNet integration advantage doesn't apply to your operations.
• You value separated hardware-service plus carrier-SIM commercial structure over bundled subscription pricing.

Pick Cradlepoint if

• Your deployment is US public safety and FirstNet integration matters operationally.
• You're standardising a US mobile fleet and want a narrower SKU range that's easier to procure and stock.
• You prefer a bundled subscription model (hardware plus NetCloud plus carrier services) over component pricing.
• Your existing operations team already runs NetCloud Manager and adding more devices to the same management plane is simpler than learning Peplink's InControl 2.

Pick Fortinet if

• You already run FortiGate firewalls across your estate and extending to cellular WAN via FortiGate cellular variants gives you a single management plane.
• Edge security (UTM) is the primary architectural driver; SD-WAN is secondary.
• You're adopting SASE architecture and want vendor-aligned components.
• Your security team owns the WAN procurement decision.

Where the comparison gets murky

For mid-tier branch SD-WAN that doesn't have specific use case characteristics (not maritime, not broadcast, not US-public-safety, not security-led), all three vendors are credible. The decision often comes down to existing operations team familiarity, vendor relationship preferences, and procurement framework alignment. Don't over-engineer the decision in this scenario.

For mixed estates running multiple use cases (e.g. branch SD-WAN plus mobile fleet plus broadcast contribution), the right answer is usually multiple vendors matched to use case rather than forcing a single vendor across all use cases. We've supported customers running Peplink for broadcast and Cradlepoint for US patrol fleet in the same overall security perimeter; both vendors interoperate with standard tunneling and management practices.

The Tech Factory perspective

We're a Peplink Gold Partner. We deploy Peplink because Peplink's depth on multi-cellular bonding, modular hardware, and maritime/broadcast use cases matches our customer base. If you're specifying a vessel network, an OB vehicle, a UK fleet rollout, or an enterprise SD-WAN deployment that needs FlexModule expansion, we're the right partner.

If your use case is genuinely better served by Cradlepoint (US FirstNet patrol fleet) or Fortinet (existing FortiGate estate extension to cellular), we'll tell you. We'd rather lose a procurement decision and keep our credibility than push Peplink into a use case it doesn't fit.

For most of our customer base, those scenarios don't apply. We sell Peplink because it's the right answer for their deployment, not because it's the only thing we know.
