Why Sternwake
Why Sternwake

Cyber coverage starts with better evidence.

Sternwake packages exposure, controls and market context so carriers can underwrite the risk you actually present.


That gap is a controls-and-evidence gap, not a technology failure, exactly what Sternwake verifies, maps and packages into every submission, so coverage is priced on what is actually true and claims are far less likely to fail on a controls technicality.

Exposure review

We profile your external attack surface before submission, so underwriters price real risk.
