7 Reasons Security Gets Deprioritised While a Business Is Scaling, and What It Costs Later

When a business moves from roughly £3m to £30m in revenue, almost everything changes at once. Headcount doubles. New markets open. The sales pipeline fills faster than delivery can keep up with it. In that environment, security is rarely cut on purpose. It gets deprioritised through a hundred small, reasonable-sounding decisions. Here are seven of the most common, and what they tend to cost once the business has grown into the risk it was ignoring.

1. Growth has a calendar. Security doesn't.
Board reporting cycles are built around revenue, pipeline and hiring. Security has no equivalent forcing function. Without a fixed review point, it waits for a trigger, usually an incident or a lost deal, instead of being managed on a schedule.

2. Nobody owns it full-time.
Below a certain size, security is a part-time responsibility bolted onto an IT manager, a CTO, or an outsourced help desk. Part-time ownership produces part-time attention, and the gaps sit exactly where nobody is looking.

3. Founders trust the team they already have.
Early hires proved themselves shipping product, not managing risk. Bringing in outside scrutiny can feel like a vote of no confidence in people who got the business this far, so the conversation gets avoided.

4. The cost is invisible until it isn't.
Security spend has no revenue line to point to. Every pound spent competes directly against a pound that could fund the next hire or the next feature, and the case for prevention is always weaker than the case for growth, right up until it isn't.

5. Compliance feels like a future problem.
Frameworks and customer security questionnaires seem like things that happen "once we're bigger", until a key enterprise deal stalls on a due diligence questionnaire nobody in the business can answer with confidence.

6. Tooling outpaces process.
Scaling businesses adopt new SaaS tools quickly to keep up with growth, but access control, offboarding and data governance rarely get revisited at the same pace. The gap between what's adopted and what's managed widens every quarter.

7. Leadership assumes IT and security are the same thing.
They're related but distinct disciplines. A team focused on keeping systems running is not the same as a function focused on reducing risk, and conflating the two leaves genuine gaps unowned by anyone.

What it costs later

None of this feels dangerous in the moment. The cost only becomes visible once the business has scaled into a bigger target with more to lose. IBM's 2025 Cost of a Data Breach Report puts the global average cost of a breach at $4.44 million, a figure that covers detection, containment, lost business and recovery. It does not capture the enterprise deal that stalls on a security questionnaire, the insurance renewal that comes back with a loaded premium, or the founder credibility spent explaining to the board why nobody saw it coming.

The businesses that avoid this outcome don't necessarily spend more on security. They simply start owning it earlier, at a size where the fix is a policy change and a few hours a week, not a full incident response and a rebuild of customer trust.

That's usually the point at which a fractional CISO earns their keep: senior security oversight, sized to the business, in place before the risk profile outgrows the informal arrangement that's been covering it so far. If any of these seven reasons sound familiar, it's worth a conversation before the trigger event does the deciding for you.
