Take to the Boardroom

What your board actually needs to hear about cyber

Three talking points, one metric, one question. Screenshot this for your next board prep.

01

We are not “protecting against hackers” — we are managing concentrated operational risk in systems the business cannot run without. Frame every conversation in business outage hours, not threat actor names.

02

The biggest gap in most programmes is not tooling. It is identity hygiene. Compromised credentials still account for the majority of material breaches I see, regardless of stack.

03

Resilience now matters more than prevention. Boards should track time-to-recovery, not just time-to-detect. If you cannot quote a tested RTO for your top three systems, that is the headline.

The Metric That MattersMean time to recovery (MTTR) for tier-one systems, measured against a tested target — not a paper RTO.
Ask Your TeamWhen did we last run a full restore from offline backups against a real production-equivalent workload — and how long did it take?

Cybersecurity FAQ — Honest Answers to the Questions Leaders Actually Ask

What does “good cybersecurity” actually look like in 2026, beyond the buzzwords?

Good cybersecurity in 2026 isn’t a tool stack or a certification — it’s whether your organization can detect, contain, and recover from a breach faster than the attacker can do real damage. That outcome rests on five fundamentals most programs still get wrong: identity governance with phishing-resistant MFA on every privileged account, asset visibility that includes cloud and SaaS (not just on-prem), patch management with measured time-to-deploy SLAs, working detection and response that’s been tested with real incident drills, and a privileged access management program that eliminates standing admin rights. If your organization has those five working, you’re ahead of 80% of mid-market enterprises. If you’re spending money on advanced tooling — AI-driven this, behavioral that — without those fundamentals locked down, you’re buying decoration on a weak foundation. Attackers don’t fail because of your sophisticated SOC; they fail because they can’t get past your identity controls or move laterally. Spend accordingly.

Which cybersecurity framework should my organization adopt — NIST CSF, ISO 27001, CIS Controls, or something else?

Stop treating frameworks as a competition — most mature programs use multiple frameworks for different purposes, and that’s correct. NIST Cybersecurity Framework (CSF 2.0) is the best risk-management and board-communication framework — it gives you the six-function model (Govern, Identify, Protect, Detect, Respond, Recover) that translates well to executives. ISO/IEC 27001 is the right choice if you need international certification, are doing business with European or Asian enterprises, or need a formal Information Security Management System for compliance. CIS Critical Security Controls v8 is the best tactical implementation guide — 18 controls with concrete actions, ideal for security teams who need a “what to do Monday morning” roadmap. The honest answer for most US mid-market organizations: use NIST CSF as the strategic framework, CIS Controls as the operational checklist, and add ISO 27001 only if you have a regulatory or commercial reason. SOC 2 is a separate beast — it’s not a framework but an audit attestation, usually required by enterprise customers. Don’t pick one framework and ignore the others; they complement each other.

How is AI changing the cybersecurity threat landscape, and how worried should I really be?

AI has fundamentally changed three things, and overhyped a fourth. First, social engineering scales: phishing emails are now grammatically perfect, contextually relevant, and personalized at industrial volume. Voice cloning and deepfake video have moved from research to commodity tooling — CFO impersonation attacks are now a real category. Second, vulnerability discovery accelerates: attackers can chain LLMs with code analysis to find exploitable bugs faster than defenders can patch them. Third, malware authoring is faster and cheaper, lowering the bar for less-skilled threat actors. The overhyped fourth thing is “AI-powered cyberattacks” as a category — most reports of these are still humans using AI as a tool, not autonomous attack agents. The defensive side has equivalent leverage: AI-driven detection is genuinely better at spotting anomalies in volume, and code review tools are catching more vulnerabilities pre-production. The actual risk profile for most enterprises hasn’t shifted dramatically yet; what’s shifted is the speed and quality of attacks at the low end. The boring fundamentals — MFA, patching, segmentation — still stop the vast majority of AI-augmented attacks because they target the same human and architectural weaknesses they always have.

What’s the difference between a CISO, a CSO, and a Director of Security — and which does my organization need?

A CISO (Chief Information Security Officer) is responsible for cyber, information, and increasingly AI-related risk — typically reporting to the CEO, CIO, or board, with budget authority and a seat at strategic discussions. A CSO (Chief Security Officer) is broader: physical security, executive protection, fraud, sometimes business continuity, in addition to cyber. In larger enterprises with complex physical and personnel security needs (banking, energy, defense contractors), the CSO role exists alongside or above the CISO. A Director of Security is the operational leader — runs the team, manages tooling, owns day-to-day execution but typically doesn’t have board-level authority or strategic budget control. Most organizations under 1,000 employees genuinely need a Director of Security, not a CISO — what they actually need is someone competent running operations, supported by a fractional or virtual CISO for strategy, board reporting, and regulatory work. Hiring a full-time CISO before you have the operational layer means you’ve hired a strategist with no team to execute. The right sequence is usually: build the security operations function first, then add the CISO when business complexity or regulatory exposure demands board-level cybersecurity leadership.

How much should we be spending on cybersecurity, and how do I know if we’re spending it well?

The headline number — security spend as a percentage of IT budget — is a misleading metric people love because it’s easy. Industry benchmarks put cybersecurity at 6-14% of IT budget for most sectors, higher in financial services and healthcare. But that ratio tells you nothing about whether the spend is effective. The better questions: What percentage of your spend is going to people versus tools? (Healthy programs are roughly 50/50 — too tool-heavy means you’ve bought capabilities you can’t operate.) What’s your mean time to detect and contain incidents? (If those numbers haven’t improved year-over-year, your spend isn’t translating to outcomes.) Are your top three security risks actually getting smaller? (If you can’t answer this, you don’t have a risk register that drives investment.) The honest signal that money is being spent well: leadership can articulate the top five enterprise risks, the controls mitigating them, and how to measure whether those controls are working. If your CISO can’t draw that diagram on a whiteboard, the budget is being spent reactively. Increase spend in proportion to documented risk reduction, not industry benchmarks.

What are the biggest cybersecurity mistakes I see organizations make repeatedly?

Five recurring failures, which I see across organizations of every size and sector. First, treating cybersecurity as an IT problem instead of a business risk discipline — the program lives in IT, doesn’t get board attention, and gets cut first when budgets tighten. Second, buying tools to compensate for weak fundamentals — paying for advanced detection while privileged accounts still use shared passwords. Third, security and engineering operating as adversaries instead of partners — leading to shadow IT, bypassed controls, and resentment that makes the next initiative harder. Fourth, mistaking compliance for security — passing an audit and then assuming you’re secure, when most attackers don’t care what frameworks you’ve certified against. Fifth, underinvesting in incident response until you need it — most organizations discover their IR plan is a 60-page document no one has practiced when the actual incident hits. The thread connecting all five: confusing activity with progress. The metric that matters is whether your organization can survive a real breach with limited damage. Plan against that outcome, not against vendor checklists.
