We select U.S.-listed companies whose core offerings are cybersecurity products or services, including network and endpoint protection, identity management, exposure management, and data resilience. This is a focused research comparison, not every software company with a security product and not an ETF portfolio. Only members present in the site’s current ranking appear. Market cap values the whole company. Price and market-cap history before the documented public listing of the current business is excluded.
Business and membership references:
Identity, endpoints, networks, and recovery solve different problems. Business-role groups help explain membership; they do not make the products interchangeable.
Subscriptions and support can create recurring revenue. Renewals, customer budgets, and platform consolidation still affect growth and margins.
Product reliability, competition, and security incidents can affect customer trust. Market-cap size does not measure how effective a security product is.
