Why UK Enterprises Choose Fortinet SD-WAN
It’s 10 a.m. at a regional firm in Manchester. The IT lead leans back in their chair, watching traffic dashboards flicker to life. A new site in Dublin goes online. Instantly, policies deploy, encryption kicks in and alerts disappear. It takes seconds.
That moment captures why UK enterprises are paying attention to Fortinet SD‑WAN.
Instead of stacking routers with extra security appliances, Fortinet built its SD‑WAN from the ground up around FortiGate. The platform treats networking and security as one system. The result has made life simpler for teams juggling multiple offices, cloud services and compliance demands.
A Different Path to SD‑WAN
Back in 2016 Fortinet launched Security Fabric. It began as an attempt to unify firewalls, intrusion detection and traffic inspection. Over time SD‑WAN logic was folded into the same control plane. Unlike vendors who bolted SD‑WAN onto routers, Fortinet baked it into a security-first architecture.
That design choice resonates with UK IT. They no longer juggle separate consoles for routing and inspection. They configure once and apply everywhere. No surprises. Audits pass. Config mismatches drop. Troubleshooting gets faster.
Why BT and Skyports Made the Switch
BT’s managed SD‑WAN service uses Fortinet at its core. Their teams can activate policies and deploy sites across the UK and Europe in hours. That speed helps them meet tight SLAs and audit cycles.
Skyports, based in London, needed secure connectivity between sites from Europe to Asia. They use broadband, LTE and MPLS networks. Fortinet’s system gives them real‑time path choice while making sure every packet is inspected. The outcome is faster traffic and tighter security with no local setup.
In both cases it’s not about features. It’s about speed and consistency. That’s what makes operations smoother.
Integration Brings Gains and Limits
Fortinet SD‑WAN cuts vendors, systems and admin effort. Training and support focus on one stack. Analytics, logging and compliance reporting flow from a single source.
But integration comes with trade offs. You can’t easily swap out the firewall or routing layer. You can use your own analytics tools but need API development and integration work.
That fit works well for organisations ready to work within one ecosystem. It is less suited to those with customised, multi‑tool environments already in place.
What the Platform Includes
Stories From the Field
A financial firm replaces manual branch deployment with Fortinet. New offices go live on day one with policies enforced. No delays. No backhaul. Everything is encrypted and monitored from start.
A regional health provider gains fast local access for staff and ensures patient data remains secure. Everything flows through inspection engines before reaching cloud services.
A local government office rolls out Fortinet between departments. IT gains visibility and control without needing local staff. Security posture is assessed centrally.
Final Thoughts
Fortinet SD‑WAN merges networking and security into a single operational model. UK teams that value consistency, compliance and faster deployment find this model appealing.
The core question is what matters more: consolidation or flexibility. If using one vendor simplifies your stack and your teams are aligned with that, Fortinet delivers. But if you need modularity or use bespoke tools, that choice may involve compromise.
This is not a question of capability. It is about architecture. Does your organisation need one system that works end to end? Or do you favour systems that fit together your way?
Summary Table for UK Decision Makers
Decision Factor | How Fortinet SD-WAN Responds |
---|
Speed of Deployment | Zero-touch provisioning and pre-configured templates enable site rollouts in hours. |
