The Fortune Cyber 60 (2026-2027) identifies significant venture-backed cybersecurity startups that have not yet completed an IPO, acquisition, or other significant exit event. Companies are organized into three alphabetical groups of 20: early stage, early growth, and growth stage. Fortune’s Cyber 60 recognizes important venture-backed startups and growth-stage companies in the cybersecurity infrastructure space. Companies are evaluated using factors including annual recurring revenue (ARR), current- and prior-year growth, business operations, and their position in the cybersecurity market.
