Darktrace

Darktrace, founded in Cambridge UK in 2013 and publicly traded in New York since 2024 (NASDAQ: DARK), pioneered self-learning AI security — its Enterprise Immune System models normal network behavior and autonomously responds to anomalies without relying on signature databases or threat intelligence feeds. This unsupervised AI approach makes it uniquely effective against novel zero-day attacks that signature-based tools miss entirely. Serving 9,300+ customers across 110 countries with $620M in annual recurring revenue, Darktrace's Cyber AI Analyst autonomously investigates 100% of security incidents — something human analysts could never match at scale. Its operational technology (OT) product protects 1,000+ critical infrastructure sites including nuclear plants and water utilities.
