Actuarial science underpins modern insurance — but in cyber, it’s been playing catch-up.

Unlike car accidents or natural disasters, cyber threats evolve daily, data is inconsistent, and risk behaviours are harder to observe. For years, cyber underwriting relied on blunt proxies: industry, headcount, or checklist questionnaires.

But in 2025, cyber actuarial science is finally starting to grow up — with new data sources, modelling techniques, and sector-specific risk intelligence.

So, the question remains: is cyber actuarial science ready for prime time?


The State of Cyber Risk Modelling Today

Most cyber insurers still face key limitations:

📉 Sparse and noisy claims data – Especially in the SME market
🔍 Inconsistent definitions of incidents – What counts as a breach, and when is it reportable?
📆 Fast-changing threat landscape – A model based on last year’s ransomware may miss today’s supply chain attacks
🔄 Static inputs – Many policies still rely on once-a-year surveys, not continuous risk monitoring
🤝 Limited transparency – Underwriters often struggle to explain premium decisions to brokers or customers

This makes actuarial accuracy difficult — and underwriting consistency harder still.


What’s Changing in 2025

🔗 Better exposure data – Platforms like Cyber Tzar provide real-time scanning and sector benchmarking
📊 Segmented risk scoring – Underwriters are no longer treating law firms and logistics firms the same
🤖 Use of AI and machine learning – For pattern recognition across breach and remediation data
📁 Growing regulatory pressure – DORA, NIS2, and SEC rules are pushing insurers to improve risk visibility
📈 Increased claims volume – More incidents = more actuarial material, especially from mid-market firms

We’re entering a new era — but models still vary wildly between insurers.


What Actuarial Teams Need to Make It Work

  1. Granular, normalised risk inputs – Not just self-assessments, but actual vulnerability and compliance data

  2. Vendor and supply chain context – Claims often stem from indirect risk, not internal failure

  3. Temporal modelling – Exposure today may differ greatly from a month ago

  4. Sector-aware baselining – What’s ‘normal’ for a school is not for a crypto exchange

  5. Feedback loops – Integrating claims outcomes to update assumptions and pricing


Where Cyber Tzar Fits

Cyber Tzar supports cyber insurers, MGAs, and actuarial teams with:

✅ Real-time, external risk scans across insured portfolios
✅ Sector-specific benchmarks for schools, legal, defence, and more
✅ Exposure modelling down to asset and supplier level
✅ Risk scoring that maps to likelihood and impact
✅ Dashboards to support underwriters, brokers, and pricing committees

We help bridge the gap between raw cyber signals and actuarial intelligence — enabling smarter cover, clearer pricing, and better claims preparedness.
