The Hidden Cyber Risks in Your Firm: It’s Not the Tech, It’s the Habits

In accountancy firms, the greatest cybersecurity threats often don’t come from hackers’ sophisticated tools, they come from everyday human habits. A password shared in a hurry. A file downloaded on an unsecured Wi-Fi connection. A phishing email opened between client calls.

These small actions go unnoticed until they trigger a breach, by which time the damage is done.

Why Traditional Training Fails

Most firms rely on annual, tick-box training modules. They satisfy compliance requirements but fall short for three reasons:

  1. Generic and forgettable
    One-size-fits-all training ignores individual behaviours and is quickly forgotten once the box is ticked.

  2. No link to daily workflow
    Staff aren’t shown how risks connect to their real-world tasks, client emails, reconciliations, and document sharing.

  3. No behavioural change
    Cybersecurity isn’t a knowledge problem; it’s a habit problem. Without reinforcement and accountability, bad habits persist.

The New Approach: Behaviour-Centric Security

To build resilience, leaders need to focus on changing daily behaviours, not just delivering information. That means:

1.  Personalised Risk Awareness

Not all employees present the same risk. A payroll assistant handling sensitive PII has a very different risk profile to a partner working on M&A transactions. Leaders must:

  • Use risk assessments and monitoring to identify where human vulnerabilities are concentrated.

  • Tailor training and interventions to individual roles and behaviours, rather than issuing generic content.

2.  Continuous Micro-Learning

Instead of “one and done” annual training, firms should adopt year-round reinforcement:

  • Bite-sized learning modules linked to real scenarios employees face (e.g., spotting a fake invoice).

  • Just-in-time nudges delivered at the moment of risk, for example, a reminder when accessing data remotely.

  • Ongoing phishing simulations and gamified testing to keep awareness fresh.

3. Embed Security in Culture

Security should become part of the firm’s identity, not a compliance chore:

  • Make cyber hygiene as routine as balancing a ledger.

  • Celebrate and reward good security behaviours just like you would great client service.

  • Encourage staff to speak up without fear if they make a mistake, faster reporting reduces damage.

4. Leadership by Example

Culture flows from the top. Partners and managers must:

  • Consistently model strong practices (e.g., never emailing sensitive files unencrypted).

  • Share openly how they manage risks in their own work.

  • Demonstrate that no one is exempt from following protocols, not even senior leaders.

The Leadership Call to Action

As a leader, it’s time to reframe cybersecurity. It’s not just about firewalls and software, it’s about people and behaviours. Here’s your starting point:

  • Audit human risks: Map out where risky habits live in your firm. Look beyond IT systems to daily workflows.

  • Rebuild your training strategy: Scrap generic annual modules. Shift to tailored, continuous, and habit-focused learning.

  • Invest in culture change: Position cybersecurity as a shared responsibility tied directly to client trust, not just IT’s job.

  • Measure what matters: Don’t just count training completions. Track reductions in phishing click rates, password hygiene improvements, and speed of incident reporting.

  • Communicate confidence: Make cybersecurity part of your client value proposition. A firm that can prove its resilience has a competitive edge.

The firms that thrive in the next decade won’t just have the best compliance frameworks, they’ll have the safest habits. Your role as a leader is to make cybersecurity a living, breathing part of firm culture.

Now is the time to ask:

Are our people prepared to be our strongest defence? Or will hidden habits remain our biggest risk?
