Summary
👤
Senior🎓
Top SchoolJoe Rozner is a Staff Security Engineer and founder with 15 years of experience building offensive security, security engineering, application security, and identity systems across consumer-scale companies. He has led and scaled Red Team and offensive programs at Yahoo—delivering enterprise-wide passkey and hardware-backed SSH deployments, spearheading detections that protected hundreds of millions of users, and influencing multi-hundred-million dollar M&A decisions. As CEO of Based Security he’s commercializing zero trust solutions rooted in immovable, attestable, hardware-backed identities, and he joins Snap bringing deep hands-on exploit development, source-audit, and remediation experience. Joe’s background as a software engineer and inventor (contributions to patented products and tooling like ASHIRT) gives him rare fluency across product, engineering, and security operations. He’s known for driving measurable outcomes—100% device compliance, large cost savings from program optimization, and sustained team capability growth—while mentoring others to rapid promotion. Based in Los Angeles, he combines startup-builder pragmatism with enterprise-scale leadership and a strong bias toward hardware-backed, provable security controls.
