The danger of ‘practically unsinkable’ thinking

The danger of ‘practically unsinkable’ thinking

In 1912, the RMS Titanic set sail as the most advanced ship ever built, described at the time as “practically unsinkable.” The engineering was exceptional. The confidence was genuine. But belief in robustness did not create control over unseen risk.

Ice warnings were received.

Speed was maintained.

Lifeboat capacity was reduced.

Optimism quietly substituted for visibility. 

 

From historic failure to modern risk

In technology environments today, the same pattern appears in more subtle forms.

We assume resilience because systems are modern, because suppliers are credible, because teams are capable, because incidents haven’t happened yet. Confidence builds gradually, reinforced by stability and performance. But without clear, shared visibility, confidence becomes assumption - but assumption is not control.

Most organisations do not lose control of their digital estates dramatically. They drift.

Cloud adoption accelerates. Business units procure SaaS to maintain pace. Acquisitions are integrated quickly because commercial logic demands it. Access is extended to avoid slowing delivery. Temporary fixes quietly become embedded architecture. Nothing feels reckless. In fact, much of it feels like progress.

And often, performance improves.

But while the business grows, complexity accumulates. Integrations layer upon integrations. Identity structures expand. Dependencies multiply. Documentation lags slightly behind reality. Ownership becomes implied rather than explicit. The estate continues to function, sometimes exceptionally well, and yet the gap between what is assumed and what is evidenced begins to widen.

This is where governance confidence can detach from operational truth.

 

The confidence gap

Ask a board whether the organisation understands its technology estate and the answer will almost always be yes. Reporting exists. Risk registers are maintained. External providers are engaged. Assurance frameworks are in place.

Yet if that confidence were tested, if real-time evidence were required of every internet-facing asset, every privileged identity, every revenue-critical integration and its downstream dependency - how quickly and coherently could it be assembled?

That question is no longer theoretical.

Regulatory direction, reinforced by developments such as the UK’s proposed Cyber Security and Resilience Bill, reflects a broader shift: digital resilience is moving firmly into the realm of board accountability. It is not enough to have policies. It is not enough to have tooling. Organisations are increasingly expected to demonstrate oversight, to show not just that controls exist, but that they are grounded in a current and accurate understanding of the estate.

You cannot demonstrate control over what you cannot clearly see.

It is tempting to categorise this purely as a cyber issue. After all, breaches and ransomware events dominate headlines. But cyber incidents are often the visible consequence of something more structural. Beneath them sit quieter weaknesses: undocumented integrations, inherited access that was never rationalised, partially integrated acquisitions, systems that function but are not fully understood in context.

Complexity is not inherently problematic. Modern organisations are necessarily complex. The risk lies in unmanaged or poorly documented complexity, in interdependencies that exist but are not articulated, in ownership that has blurred over time, in the quiet assumption that “someone must be looking after that.”

Left unexamined, that complexity becomes operational exposure. Operational exposure becomes cyber exposure. Sustained exposure invites regulatory scrutiny, insurance friction and reputational strain. In strategic moments - investment, acquisition, partnership - it introduces uncertainty. Not because failure has occurred, but because clarity cannot be demonstrated with confidence.

That is where valuation conversations subtly change tone.

The most uncomfortable moments for leadership rarely stem from obvious collapse. They arise when confidence is challenged and the supporting evidence is slower, patchier or more fragmented than expected. The architecture diagram still looks reassuring. The dashboards still report green. Yet under scrutiny, the narrative requires explanation.

The estate performs - until it is interrogated.

Organisations that are navigating this well tend to share a common discipline. They treat visibility as continuous rather than periodic. They reconcile assumption with evidence. They align operational and cyber resilience rather than allowing them to evolve in parallel. They simplify where complexity adds little strategic value and reassert clear ownership where it has drifted


Restoring clarity through control

Increasingly, the conversations we are having with leadership teams - particularly those operating in growth environments - are less about acquiring additional technology and more about restoring coherence. At FluidOne, that often begins with a simple but uncomfortable exercise: mapping what is believed to be true about the estate against what can be evidenced today.

That reconciliation is rarely dramatic. But it is powerful. It transforms confidence from inherited belief into defensible governance. It turns resilience from a declared attribute into a demonstrable one.

Digital estates rarely fail loudly at first. They erode quietly, behind performance metrics and familiar diagrams. Stability can mask fragility for longer than most expect.

The Titanic did not lack engineering excellence. It lacked full appreciation of the environment it was navigating.

Optimism is comfortable.

But optimism is not a control.

Clarity is.

 

The path forward?

Modern estates don’t fail because technology is weak; they fail because visibility drifts. At FluidOne, our Business and Enterprise IT divisions, together with CSA Cyber, help organisations restore that visibility by reconciling what’s believed with what’s real. The outcome is stronger governance, cleaner architecture and resilience that can be demonstrated, not just declared.
