Cyence

Cyence is a cyber risk analytics and modeling solution — originally an independent InsurTech startup (backed by IVP and others) and acquired by Guidewire in 2017 — that helps insurers, reinsurers, brokers, and managing general agents quantify, underwrite, and manage cyber insurance risk in financial terms. It combines internet-scale data collection, data science, and economic loss modeling to produce exposure signals, breach-probability estimates, and portfolio accumulation and catastrophe scenarios. Cyence data and scores are delivered to carriers through Guidewire Cloud and are available via a REST API for pricing, risk selection, and underwriting workflow automation. API access is partner-gated through a Guidewire account rather than a public self-serve developer portal.

Cyence publishes 1 API on the APIs.io network. Tagged areas include Company, Cybersecurity, Cyber Risk, Insurance, and Insurtech.

Cyence’s developer surface includes documentation, API reference, engineering blog, and 6 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Insurance regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/cyence: open an issue to ask a question, or submit a pull request to add artifacts.
