At-Bay

At-Bay is a San Francisco-based cyber insurance provider that uses continuous, technology-driven risk assessment to underwrite and manage cyber liability policies. The company scans insured businesses' external attack surfaces throughout the policy period, monitoring for vulnerabilities like unpatched software, misconfigured services, and new threat indicators, and proactively contacts policyholders with specific remediation guidance before a breach occurs. At-Bay also offers tech E&O and executive lines coverage and serves businesses ranging from SMBs to mid-market enterprises. The company's data-driven underwriting model allows it to price risk more accurately and sustainably than traditional insurers relying on static application data. Founded in 2016 with offices in San Francisco and Tel Aviv, At-Bay raised over $300M from investors including Lightspeed Venture Partners, ION Crossover Partners, and Munich Re Ventures. It competes with Coalition, Cowbell Cyber, and incumbent cyber insurers.
