Measuring ROI of SD-WAN Deployments

Measuring ROI on Fortinet SD-WAN Projects: A Practical Guide

It’s barely past my third coffee—and truth be told, this stuff has me buzzing more than the hardware hacking village at DefCon I’ve just returned from. For sure, measuring ROI on Fortinet SD-WAN projects is not only crunching numbers and displaying pretty graphs. No, it’s about actual financial and operational victories, straight from the trenches of PJ Network’s war room.

From the day it all began for me as a network admin all the way back in ’93 (yes, there was a time I grappled with legacy muxes like they were pieces of some kind of ancient puzzle), I came to realize the devil’s in the details—and SD-WAN is no different.

ROI Metrics The Starting Line

Here’s the problem — too many companies leap into SD-WAN deployments in pursuit of buzzwords like agility or AI-driven security (and let’s face it… AI-driven is typically code for snake oil). Before you can even concern yourself with ROI, it’s a necessity that you have your baseline metrics defined.

For our clients, particularly for the three banks we recently assisted in updating their zero-trust architecture, that involved collecting baseline data concerning:

Without it, any ROI conversation is smoke and mirrors.

Data Collection Small Data Not Big Data

Collecting the right data is a bit like making a perfect biriyani — if you overdo the spices or throw in the wrong ones, you’ll ruin the dish. If you have too few facts, your model for ROI won’t matter.

We use automated tooling tied in with Fortinet’s SD-WAN console to pull:

Plus, PJ Networks always adds in some old school by-hand checks, because tech can lie or screw up sometimes, too. Remember the Slammer worm in 2003? That taught me never to put too much trust in systems.

Cost-Benefit The Realism of the Money Truth-Teller

Trying to figure out the ROI without doing an actual cost-benefit analysis is like driving a hot sports car without a speedometer—you know you’re going to your destination quick but who knows how fast or if it’s worth it.

And this is how we parse it for Fortinet SD-WAN projects:

But — work with me here people — that doesn’t necessarily mean the payoff is always enough of the financial variety. Other times, what you get in return is resilience or flexibility that does not always square tidily on a ledger.

Dashboard Creation Visualize to Realize

If you don’t see it, you can’t become it. And that’s a little bit how ROI dashboards came into effect here at PJ Networks.

We build personalized dashboards for every client that visualize:

This dashboard is not just for the IT crew, it’s for execs that need to understand. Take one look and you should be able to tell Is this investment worth it? without requiring a PhD in networking.

PJ Networks ROI Model The Secret Sauce Behind It All

I’ll be honest—our model has come a long way since I first struggled to figure out what complex network solutions were worth. What works for us today is:

  1. BaseType everything – You need to know where you are starting if you’re going to make a decision.
  2. Monthly reporting – We won’t set and forget. It helps to catch problems early on.
  3. Optimization recommendations – Useless the data except for action. We recommend configuration tweaks, and sometimes even policy changes, each month.
  4. Client involvement – Your feedback shapes the model. No black box guessing here.

Customers say they love the model because it reflects the way they think about their business, not mere geeky metrics.

Keep on Improving It is an Ongoing Learning Experience

Deploying Fortinet SD-WAN isn’t a one-and-done project. Markets change. Threats evolve. Your network needs to adapt. Our ROI measurement also serves as a process of perpetual improvement. Here is what that looks like in practice:

Here’s the kicker If you think you can just roll out SD-WAN and then coast, guess again. It’s monitoring and tuning that make or destroy your long-term ROI. I can’t stress this enough.


Quick Take


Rolling back to when I was young and working on the floor, f**king with PSTN muxes, and staring at the fallout of the Slammer worm taught me that resilience and solid metrics often save the day.

We have the resources available to deliver both via Fortinet’s SD-WAN—but only if you measure smart.

Me? I guess I’m just happy that after all these years behind the helm of PJ Networks, I still get to play with my toys in terms of network performance and help clients protect their assets. It’s a tricky balance — sort of like making your mom’s favorite family recipe but adapting it to modern diets.

For those that find themselves wrestling with deciding whether to make a bet on Fortinet’s SD-WAN solution, what I can tell you from my gut is this don’t invest because this is the latest and greatest thing. Searching for concrete returns — in dollars but also in greater security. Because who doesn’t love saving money on their phone bill? That’s the real win. And yes, your CFO will like it, as well.
