About this screen
Cybersecurity companies protect networks, devices, cloud workloads, user identities and data from attacks. Security budgets have proven more resilient than many other IT budgets, because breaches are costly and regulations require stronger controls. The group mixes broad platform vendors with specialists in a single area such as email, identity or vulnerability management, and many sell through subscriptions.
The list uses a hand-reviewed theme tag for companies whose business descriptions center on security; it may not capture every vendor. The Growth tab compares revenue growth across the group. Gross margin in Profitability and EV/Sales in Valuation show how the market prices that growth. Platform vendors often grow by adding products, while specialists face pressure as customers consolidate suppliers.
