Bundles active security-control monitoring and alerting directly into the cyber-insurance policy itself -- a genuinely different model than traditional risk-transfer-only insurers, pioneered alongside a small number of peers like At-Bay.

Operating since 2017 with a very large policyholder base implied by its scale of funding and valuation; long track record of underwriting and claims handling at meaningful volume.

Raised a $205M Series E at a $3.5B valuation in 2021, bringing total funding to $860M -- among the largest funding hauls of any company in this batch, though the most recent large round dates to 2021.

Materially changed the cyber-insurance business model by combining active risk monitoring with underwriting, helping define the 'active insurance' category that others have since followed.

Efficacy (e.g. claims-reduction rates for monitored policyholders) is primarily company-reported; independent actuarial validation was not identified in sources reviewed.

Cyber insurance combined with proactive risk monitoring addresses a durable and growing need as breach frequency, severity and regulatory exposure continue rising.
