About Us

Coalition is the leading provider of cyber insurance and security, combining comprehensive insurance and proactive cybersecurity tools to help businesses manage and mitigate cyber risk. Coalition’s unique product offerings combine best-in-class insurance and proactive cybersecurity tools to help keep businesses safe. Cyber losses cost the global economy upwards of $1.5 trillion each year, and yet the majority of businesses are under-insured and under-prepared to manage and mitigate the risks of an increasingly digital world. Coalition is addressing this gap by providing no-cost cybersecurity tools to prevent losses, security and incident response services to contain them, and comprehensive cyber insurance to help organizations recover. We have over 25,000 customers, ranging from small and mid-sized businesses to Fortune 500 companies. 

Founded in 2017, Coalition has raised $125M from a number of top tier global investment firms including Ribbit Capital, Greenoaks Capital, Valor Equity Partners, Felicis Ventures, and Vy Capital.  Headquartered in San Francisco, Coalition’s team is distributed across more than 15 locations globally, including Austin, Washington DC, Denver, Canada and Portugal.
