Cyber insurance startup At-Bay raises $185M Series D led by Icon Ventures and Lightspeed Venture Partners at a $1.35B valuation, amid the global ransomware boom

Context & Ripple Effects
This round is the third raise inside 18 months for At-Bay, which had pulled a $34M Series B in early 2020 and another $34M Series C led by Qumra Capital just ten months later — a cadence that tracks the ransomware boom and GDPR-driven demand the coverage cites. The step-up from two consecutive $34M rounds to $185M signals investors treating continuous tech-stack monitoring as the differentiator in cyber underwriting.
The arc has an epilogue the corpus makes explicit: five years later Munich Re agrees to buy At-Bay for $575M, less than half the $1.35B valuation set in this round, against $276M total raised.
First-order effects
- At-Bay's war chest nearly doubles its cumulative funding in one round, letting it scale underwriting capacity while rival cyber insurer Resilience — which bundles ransomware-defense services with policies ($80M Series C) — races to match the model months later.
- Icon Ventures and Lightspeed Venture Partners take lead positions at a $1.35B mark, pricing At-Bay as a category leader rather than a startup.
Second-order effects
- Traditional insurers now compete against carriers whose underwriting is fed by continuous vulnerability monitoring of policyholders' own systems, pushing the whole market toward security-services-plus-policy bundles.
- The ransomware boom that inflated this valuation also funds prevention startups like Zero Networks ($55M), splitting attacker-side demand across both insurance and defense vendors.
Third-order effects
- Munich Re's later $575M purchase shows where the structure settles: standalone cyber insurers exit to balance-sheet-heavy insurance groups once growth-stage capital reprices, leaving 2021-era marks like $1.35B unrecovered.
- If the pattern holds, cyber risk migrates from niche insurtech balance sheets onto global reinsurers, with monitoring technology retained as the underwriting moat rather than the company itself.
The trend: Cyber insurance is cycling through boom-stage mega-rounds toward consolidation under global insurance groups, as Munich Re's discounted acquisition of At-Bay demonstrates.
