5 x CISO | Founder & CEO | Startup Security Advisor
Bil Harmer has been breaking, building, and leading in security for over 25 years. He’s led security programs for startups, governments, and global financial institutions—and knows firsthand how to balance speed with protection when the stakes are high. In 2007, he pioneered a hybrid SAS70/ISO methodology that laid the groundwork for modern SaaS security audits, years before SOC2 became table stakes.
A sought-after speaker and advisor, Bil has presented across North America and Europe at events like RSA, ISSA, GrrCon, and CSA. His work has appeared in Dark Reading, Data Informed, Security Intelligence, and more. He’s advised companies like Adallom, Trust Science, ShieldX, and Integris, and held senior security leadership roles at SAP/SuccessFactors, Zscaler, SecureAuth and Craft Ventures. Today, he runs Killswitch Advisory—a security firm for companies that need sharp, decisive infosec leadership without the corporate theater.
