Top 10 US Cyber Insurance Providers 2026

Travelers writes cyber cover for small and mid-sized commercial clients through its CyberRisk policies, usually sold alongside the property and liability lines those buyers already hold with it. Its 2024 acquisition of Corvus Insurance added a cyber underwriting platform built on outside-in scanning of an applicant's internet-exposed infrastructure, which is what lets it price accounts too small to justify a manual security review.

Beazley commands the US cyber market with $800 million in dedicated premiums, establishing itself as a Lloyd’s specialist with the first dedicated cyber syndicate launched in 1999. Its Breach Response team manages over 3,000 incidents annually. This data-led approach cements Beazley as a market leader in US healthcare and financial services cyber coverage, using 25 years of underwriting expertise to mitigate complex risks.

CNA Financial is a Chicago-based commercial insurer whose cyber line, CNA NetProtect, is written mainly for mid-market and professional-services businesses. The company was itself hit by the Phoenix CryptoLocker ransomware in March 2021 and was reported to have paid a $40 million ransom, one of the largest payments publicly attributed to a US company.

Munich Re is one of the largest cyber reinsurers and publishes an annual survey of the global cyber insurance market that other underwriters cite for sizing. Because it writes cyber both directly through its specialty units and as a reinsurer standing behind other carriers, it sees loss data from both ends of the chain.

Corvus was a cyber-insurance managing general agent that priced and monitored policies using continuous external scanning of a client's internet-facing systems, warning policyholders about exposures before they turned into claims. Travelers acquired the company in January 2024, so its underwriting now sits inside Travelers rather than operating as an independent provider.

Coalition is a cyber insurance managing general agent, founded in San Francisco in 2017, that underwrites on other carriers' capacity rather than its own balance sheet. Its distinguishing feature is Coalition Control, which continuously scans a policyholder's internet-facing systems and warns them about exposed services before they are exploited — insurance sold alongside monitoring rather than after the fact.

At-Bay is a US cyber insurance specialist, founded in 2016, that underwrites policies alongside continuous scanning of a client's internet-facing attack surface, alerting insureds to exposed services before they are exploited. It markets this bundling of security monitoring with the policy as “Active Insurance” and focuses on small and mid-market commercial buyers.
