Cyber Insurance & Risk Transfer
Moves residual risk onto someone else’s balance sheet.
Overview
Insurance is the treatment option most security programmes handle worst: bought by finance, priced on a security posture the security team never sees, and claimed against under terms nobody read until an incident. The modern cyber market is technical — Coalition, At-Bay and Resilience underwrite from continuous external scanning and bundle active risk management, so your controls change your premium and sometimes your coverage. The governance job is to make residual risk, limits, retentions and exclusions a single evidenced decision rather than three disconnected ones.
Right after the core controls are real — insurers price on posture, so buying too early costs more for less.
Advantages
- The only control that transfers financial consequence rather than reducing likelihood
- Underwriting scans give you a free, adversarial outside view of your own attack surface
- Incident response retainers and breach counsel bundled into policies have real operational value
- Insurer control requirements have done more to drive MFA and EDR adoption than most frameworks
- Quantified residual risk makes limit and retention selection an evidenced decision
Trade-offs
- Exclusions — war, infrastructure, unpatched known vulnerabilities — are where claims actually fail
- Application misstatements can void cover; the security team must review what finance submits
- Premiums and requirements move sharply with the loss environment, so budgeting is unstable
- Bundled security tooling is rarely best-of-breed and can create dependency on the carrier
- Insurance is not a control — it pays after the loss and does nothing for the loss you cannot buy back
Open-source option
Risk transfer is a regulated financial product; there is no open-source equivalent and cannot be. The adjacent open capability is quantification — pyfair and the FAIR standard let you model residual risk yourself so you can challenge a broker’s limit recommendation with your own numbers rather than accepting theirs.
