Cyber insurance is not a substitute for cybersecurity. For a French SME, it is a partial risk transfer contract that must align with internal controls, backups, continuity planning, customer obligations and accounting evidence of losses.
Executive Summary#
Insurance premiums covering business activity are generally treated as operating expenses, subject to the specific situation. The key issue is file quality: insurer questionnaire, exclusions, deductible, coverage cap, security evidence, incident trail and ability to quantify business interruption and remediation costs.
Decision Matrix#
| Leadership situation | Working option | Control point |
|---|---|---|
| SME without cyber risk mapping | Diagnostic before policy | Critical assets, backups, access and vendors |
| E-commerce or SaaS dependent on systems | Interruption and data coverage | Business interruption and customer obligations |
| Complex insurer questionnaire | Documented answers | Do not claim controls that do not exist |
| Incident already occurred | Evidence file | Timeline, costs, invoices and communication |
Control Points to Document#
- Policy: scope, deductible, cap, exclusions and waiting period.
- Accounting: premiums, indemnities, interruption losses and replaced assets.
- Tax: match expenses and income to the correct period.
- Evidence: backups, MFA, logs, continuity plan and restoration tests.
- Governance: who reports, signs and communicates during an incident.
Operational Example#
Illustration: an SME pays a EUR 6,000 annual premium with a EUR 10,000 deductible. After ransomware, it incurs EUR 18,000 of IT costs and loses three days of sales. Without incident log, quotes, invoices, accounting export and backup evidence, indemnification may be delayed or disputed.
Our Chartered Accountant's View#
We connect insurance, accounting and management reporting. A cyber policy should define how losses will be measured: lost margin, internal costs, vendors, hardware replacement, communication and legal fees. Without method, the claim becomes vague negotiation.
The Underestimated Risk#
The underestimated risk is an unintentional false statement in the questionnaire. Claiming MFA, offline backup or continuity planning when not effectively deployed can weaken coverage.
What Leadership Must Decide#
- Name an owner for the cyber insurance file.
- Run a cyber diagnostic before renewal.
- Document controls declared to the insurer.
- Prepare accounting evidence procedures for incidents.
- Connect cyber, continuity, GDPR, customer contracts and IT budget.
2026 Watchpoints#
- French public SME cybersecurity resources were updated in 2026.
- NIS2 may influence customer requirements even for SMEs not directly in scope.
- Cyber insurance does not always cover wire fraud, ransom, fines or backup failures.
- Exclusions should be reviewed with CFO, cyber provider and broker.

Frequently asked questions
Is a French cyber insurance premium deductible?+
When it covers business risk, the premium is generally an operating expense, subject to ordinary deductibility conditions and contract review.
Does cyber insurance cover ransom payments?+
Not always. Guarantees, exclusions, legal rules and reporting requirements must be checked in the policy.
What should the CFO prepare?+
A loss measurement method, list of evidence, emergency spending approval workflow and accounting tracking for insurance proceeds.
Is the insurer questionnaire binding?+
Yes. Answers should match controls actually in place. Approximate answers can weaken the guarantee.
Are cyber insurance and NIS2 linked?+
Indirectly. NIS2 can raise governance expectations and influence questionnaires, customers and procurement requirements.
