Albert Yu is a security-focused technology leader and Co-Founder & CTO with over two decades of experience building secure systems and teams across Google, Atlassian, and Yahoo. He blends hands-on engineering—contributions to large-scale tools like Gryffin and cloud infrastructure code for Google Cloud—with deep security expertise spanning cryptography, incident response, protocol and code review, and risk governance. A part-time cryptographer with a PhD, he has a track record of turning research into production-ready defenses (e.g., tainted-PhantomJS XSS detection and an HTML context parser used for contextual templating). At Atlassian he led the design and delivery of a unified permission service on AWS; at Google he helped make GCP usage secure by default and worked on root CA responsibilities at GTS. Known for pragmatic, scalable controls and an ability to “see how systems break,” he combines startup grit with enterprise-grade security rigor. Based in California, he actively contributes to open source and prefers conversations that demonstrate practical security failures and controls learned from them.
Gryffin is a large scale web security scanning platform.
