The Internet Runs on Invisible ID Cards. Keyfactor Wants to Manage Every One.
Certificates quietly decide which machines, workloads, devices, code, and AI agents can be trusted. Keyfactor has spent 25 years turning that hidden machinery into infrastructure security teams can actually see and control.
QuSecure
QuSecure is a San Mateo, California cybersecurity company that helps organizations defend against the threat that quantum computers pose to today's encryption. Its flagship platform, QuProtect, is a crypto-agility layer that discovers an organization's cryptographic assets and lets them migrate to NIST-standardized post-quantum cryptography without ripping out existing infrastructure or rewriting code. Founded in 2019 and led by CEO Rebecca Krauthamer, QuSecure has demonstrated quantum-resilient communications over live satellite links, won U.S. Army and Air Force contracts, and was named a 2026 World Economic Forum Technology Pioneer.
Rebecca Krauthamer
Rebecca Krauthamer is the co-founder and CEO of QuSecure, a San Mateo company building software that lets governments and banks swap out their encryption before quantum computers learn to break it. A Stanford Symbolic Systems graduate who jumped from AI to quantum in 2017, she turned a U.S. Air Force grant into a Series A-funded leader in post-quantum cryptography, counting the U.S. Army, Air Force, and Banco Sabadell among its users. A Forbes 30 Under 30 honoree and World Economic Forum council member, she argues cybersecurity is a mission for humanity, not just a product category.
