The £18,000 Saving That Cost £200,000 in Revenue Ever cut a cost that seemed obviously wasteful, only to discover you'd destroyed something far more valuable? Welcome to the Doorman Fallacy —it's probably happening in your business right now. In this episode, Noel Bradford introduces a concept from marketing expert Rory Sutherland's book "Alchemy" that explains precisely why "sensible" security cost-cutting so often leads to catastrophic consequences. Through five devastating real-world case studies, we explore how businesses optimise themselves into oblivion by defining roles too narrowly and measuring only what's easy to count. Spoiler alert: The doorman does far more than open doors. And your security measures do far more than their obvious functions. What You'll Learn The Core Concept What the Doorman Fallacy is and why it matters for cybersecurity The difference between nominal functions (what something obviously does) and actual functions (what it really does) Why efficiency optimisation without a complete understanding is just expensive destruction The five-question framework for avoiding Doorman Fallacy mistakes Five Catastrophic Case Studies 1. The Security Training Fallacy (Chapter 2) How cutting £12,000 in training led to a £70,000 Business Email Compromise attack Why training isn't about delivering information—it's about building culture The invisible value: shared language, verification frameworks, psychological safety What to measure instead of cost-per-employee-hour 2. The Cyber Insurance Fallacy (Chapter 3) The software company that saved £18,000 and lost £200,000 in client contracts Why insurance isn't just financial protection—it's a market signal Hidden benefits: third-party validation, incident response capability, customer confidence How cancelling coverage destroyed vendor relationships and sales opportunities 3. The Dave Automation Fallacy (Chapter 4) Insurance broker spent £100,000+ replacing a £50,000 IT person The £15,000 server upgrade that Dave would have known was unnecessary Institutional knowledge you can't document: vendor relationships, crisis judgment, organisational politics Why ticketing systems can't replace anthropological understanding 4. The MFA Friction Fallacy (Chapter 5) Fifteen seconds of "friction" versus three weeks of crisis response The retail client who removed MFA and suffered £65,000 in direct incident costs Why attackers specifically target businesses without MFA The reputational damage you can't quantify until it's too late 5. The Vendor Relationship Fallacy (Chapter 6) Solicitors saved £4,800 annually, lost a £150,000 client Why "identical services" aren't actually identical The difference between contractual obligations and genuine partnerships What happens when you need flexibility and you've burned your bridges Key Statistics & Case Studies 42% of business applications are unauthorised Shadow IT (relevant context) £47,000 BEC loss vs £12,000 annual training savings £200,000 lost revenue vs £18,000 insurance savings £100,000+ replacement costs vs £50,000 salary £65,000 incident costs vs marginal productivity gains £150,000 lost client vs £4,800 vendor savings Common pattern: Small measurable savings, catastrophic unmeasurable consequences. The Five-Question Framework Before cutting any security costs, ask yourself: What's the nominal function versus the actual function? What does it obviously do vs what does it really do? What invisible benefits will disappear? Be specific: not "provides value" but "provides priority incident response during emergencies" How would we replace those invisible benefits? If you can't answer this, you're making a Doorman Fallacy mistake What's the actual cost-benefit analysis, including invisible factors? Not just "save £8,000" but "save £8,000, lose security culture, increase incident risk" What's the cost of being wrong? In cybersecurity, the cost of being wrong almost always exceeds the cost of maintaining protection Practical Takeaways What to Do Tomorrow Review your most recent efficiency or cost-cutting decision. Ask: Did we define this function too narrowly? What invisible value might we have destroyed? Are we experiencing consequences we haven't connected to that decision? Better Metrics for Security Investments Instead of measuring cost-per-hour or savings-per-quarter, measure: Incident reporting rates (should go UP with good training) Verification procedure usage frequency Time-to-report for security concerns Vendor response times during emergencies Employee confidence in raising concerns Making Trade-Offs Honestly Budget constraints are legitimate. The solution isn't "never cut anything." It's: Acknowledge what you're sacrificing when you cut Admit the risks you're accepting Have plans for replacing invisible functions Make consequences visible during decision-making Ensure decision-makers bear some responsibility for outcomes Quotable Moments "The doorman's job is opening doors. So we replaced him with an automatic door. Saved £35,000 a year. Lost £200,000 in revenue because the hotel stopped feeling luxurious. That's the Doorman Fallacy." — Noel "Security training's nominal function is delivering information. Its actual function is building culture. Cut the training, lose the culture, then wonder why nobody reports suspicious emails anymore." — Noel "We saved £8,000 on training. Spent £70,000 on the Business Email Compromise attack that training would have prevented. The CFO was very proud of the efficiency gains." — Noel "You can't prove a negative. Can't show the value of the disasters you prevented because they didn't happen. So the training gets cut, the insurance gets cancelled, and everyone acts surprised when the predictable occurs." — Mauven "The efficiency consultant's dream outcome: Measurable cost eliminated, unmeasurable value destroyed, everyone confused about why things feel worse despite the improvement." — Noel Chapter Timestamps 00:00 - Pre-Roll: The Most Expensive Cost-Saving Decision 02:15 - Intro: Why Marketing Books Matter for Cybersecurity 05:30 - Chapter 1: The Book, The Fallacy, The Revelation 12:00 - Chapter 2: The Security Training Fallacy 19:30 - Chapter 3: The Cyber Insurance Fallacy 27:00 - Chapter 4: The Dave Automation Fallacy 35:30 - Chapter 5: The MFA Friction Fallacy (+ Authentrend sponsor message) 42:00 - Chapter 6: The Vendor Relationship Fallacy 49:30 - Chapter 7: Hard-Hitting Wrap-Up & Framework 58:00 - Outro: Action Items & CTAs Total Runtime: Approximately 62 minutes Sponsored By Authentrend - Biometric FIDO2 Security Solutions This episode is brought to you by Authentrend, which provides passwordless authentication solutions that address the friction problem discussed in Chapter 5.
