The SASE platform was technically flawless. The network was secure. Access was smooth. Performance was stable. So why did the board cut the digital transformation budget the following year?

In the world of modern enterprise IT, few acronyms have captured the imagination quite like SASE — Secure Access Service Edge. The promise is compelling: simplified architecture, improved performance, unified security. But like many powerful solutions, SASE is not immune to strategic misalignment.

It started, as so many stories do, with good intentions and bad habits.

The breach wasn’t the result of advanced persistent threats or zero-day exploits. It wasn’t some masterstroke of technical wizardry. It began with a spreadsheet, a routine process, and a series of very human mistakes—each small on its own, but together enough to unlock the front door of an organisation.

This is the story of how a fictional—but very plausible because it’s based somewhat on a real-world example—security incident unfolded inside a mid-sized professional services firm, and how the right architecture—specifically a Secure Access Service Edge (SASE) approach—could have disrupted the sequence of events before any real damage was done.

The real challenge of Secure Access Service Edge (SASE) isn’t choosing a technology — it’s scaling change across a complex, dynamic organisation.

That’s why a well-executed pilot is only the beginning. To realise value at scale, you need a phased rollout strategy — one that breaks down ambition into actionable steps, balances stability with agility, and ensures that security, performance, and user experience improve together.

Too often, technology leaders face pressure to deliver everything at once. But SASE isn’t just a set of capabilities to turn on — it’s a convergence of security, networking, identity, and operations. A “big bang” approach increases risk, slows learning, and overwhelms teams.
