82+ Funded Cybersecurity Startups — $2.8B Raised, 62 Companies

Cybersecurity remains one of the most consistently funded sectors in the 2025-2026 window. Our dataset tracks 62 cybersecurity companies that raised a combined $2.8B at a $19M median round. The US accounts for 43 companies, while Israel (9) punches well above its weight — reflecting Tel Aviv's outsized cybersecurity ecosystem. The rise of AI-powered attacks has created urgent demand for AI-powered defense solutions, driving a new generation of startups focused on autonomous security operations. Application security for AI-generated code, cloud-native security posture management, and identity security are the hottest sub-categories. At Series A, 15 cybersecurity companies raised $528M at a $28M median — above the overall Series A median of $21M — as investors recognize the category's strong unit economics and enterprise willingness to pay. Notable trends include the convergence of security and compliance (GRC), the shift from detection to autonomous response, and the growing importance of supply chain security. For GTM teams, cybersecurity startups are premium prospects with above-average technology budgets. CISOs are the primary buyers for security tools, while CTO/VP Engineering buy developer security products.
