Can SMBs Afford Modern Cybersecurity?

Ransomware doesn't check your headcount. Here's what 24/7 protection really costs a business of 50 to 500 people, and how to pay for it predictably.

If you are responsible for cybersecurity at a firm of 50 to 500 people, 24/7 cyber monitoring can feel like a big-company overhead. Before budget even comes into it, two questions often come up when considering the risk. What do we actually need? And will an attack really happen to us?

The government's data answers the second question bluntly. In the Cyber Security Breaches Survey 2025/26, 65% of medium businesses and 69% of large businesses reported a breach or attack in the previous 12 months. For a business your size, an incident this year is more likely than not. The real question is what it costs you when it happens.

Most of those incidents are phishing attempts caught early. The ones that get through are a different matter. When ransomware lands, the costs stack up fast:

• Downtime. Systems go dark, orders stop and staff sit idle while overheads keep running.
• Recovery. Forensics, legal advice, data restoration and, often, a ransom demand.
• Regulatory and customer fallout. Breach notifications, potential ICO action and key contracts put at risk.
• Insurance. Higher premiums at renewal, or a claim challenged if minimum controls were missing.

Northamptonshire haulier KNP Logistics shows the worst case. In 2023, attackers guessed a single employee password, encrypted its systems and reportedly demanded around £5 million. Despite holding cyber insurance, the 158-year-old firm could not recover. It went into administration and around 700 people lost their jobs.

The Boardroom Dilemma: Why 24/7 Security Is No Longer Optional

The financial calculus has shifted. Three pressures are now converging on the mid-market at once.

• The insurance squeeze. Cyber premiums keep climbing, and insurers increasingly expect 24/7 monitoring through MDR or a SOC. Your policy is also only as good as your evidence. After a breach, the insurer's forensic team checks whether the controls you declared, such as MFA, patching and backups, were really in place. These closely mirror Cyber Essentials. If they weren't, the payout can be cut or the policy voided.
• Regulatory exposure. UK GDPR fines can reach £17.5 million or 4% of global turnover. For firms trading into the EU, NIS2 adds tight incident-reporting deadlines and direct management accountability.
• The resource reality. Your IT team works 9 to 5. Ransomware operators prefer nights, weekends and bank holidays.

Asking a stretched IT department to catch a 3am encryption event is not a strategy. It is a gamble.

The £500k+ Fallacy: The True Cost of an In-House SOC

Building your own Security Operations Center looks like control. In practice, it traps capital in depreciating assets and traps HR in a talent war you cannot win.

Here is what a genuine 24/7 in-house capability costs:

• Headcount. Round-the-clock cover needs at least five or six Tier 1 and Tier 2 analysts. At £50,000–£70,000 each plus on-costs, you pass £300,000 a year before buying a single tool.
• Technology. A SIEM, threat intelligence feeds and orchestration tooling. Each carries licence fees, and SIEM data-ingestion charges are notoriously hard to forecast.
• The churn tax. Skilled analysts often leave for enterprise roles within 12–18 months. You end up funding recruitment and training on a loop, not security.

Add it up and the £500,000 mark arrives quickly. The return on that spend is rarely what the board was promised.

Legacy MSSPs: Trading CAPEX for Hidden Sunk Costs

Faced with that maths, many heads of finance turn to a traditional Managed Security Service Provider. The invoice looks smaller. The total cost often isn't.

Watch for three hidden costs:

• Bring your own licence. You pay the provider to monitor, then pay again for the SIEM and EDR licences they monitor with.
• Hardware and onboarding. On-premise appliances and complex deployments mean heavy upfront fees and months before you see any value.
• Alert forwarding. Thousands of unverified alerts land back with your IT team. They become an unpaid triage desk, and their real work stalls.

The Financial Pivot: From CAPEX to Predictable OPEX

The financially sound move is to stop buying infrastructure altogether. Cloud-native platforms collapse the security stack and turn a volatile capital outlay into a predictable operating expense.

• Consolidate. Replace disconnected point solutions with one platform. Fewer vendors, fewer overlapping renewals, fewer integration projects.
• Remove the hardware. No appliances to buy, maintain or depreciate.
• Forecast with confidence. A subscription that scales with employee headcount, not data volume, ends the surprise ingestion bill.

Security becomes a line item you can plan around, not a shock you absorb mid-quarter.
