Summary
👤
Senior🎓
Top SchoolFrank Siebenlist is a seasoned security architect and CISO with 15+ years of experience designing and operationalizing enterprise-grade security, privacy, and compliance programs across startups and large organizations in the San Francisco Bay Area. He has led infrastructure and cryptographic initiatives at Salesforce and 23andMe—implementing PKI, HSMs, secrets management, and HITRUST/HIPAA/PCI/GDPR compliance—while currently advising FinTech and DeFi startups as an independent consultant. Frank’s background combines deep hands-on engineering (Python, Java, crypto libraries, hybrid cloud migrations) with program-level leadership in incident response, penetration testing, and security operations. He traces his roots to research and large-scale scientific projects at Argonne and the University of Chicago, where he helped architect the Globus Toolkit and contributed to influential security standards. Comfortable translating regulatory requirements into executable technical plans, he is equally at home prototyping crypto services as he is briefing executives and investors. An unusual strength is his longevity across academia, start-ups, and Fortune-level firms, giving him a rare perspective on both cutting-edge research and production-ready security controls.
