Guillaume Ross is a cybersecurity leader with experience building and leading security programs across large enterprises, cybersecurity startups and regulated financial services. He previously led security at Finaptic, Fleet and JupiterOne, combining technical depth in security engineering and architecture with experience leading teams and advising executives.
At Finaptic, later acquired by National Bank, he built the security program from the ground up for a cloud-based banking-as-a-service platform operating within Canada’s regulatory framework. Through Caffeine Security, he now advises technology companies, founders and investors on security strategy, product development and due diligence.
Guillaume has little patience for security “best practices” followed simply because everyone else follows them, even when they accomplish little. He favours decisions grounded in actual threats, evidence and a clear understanding of what the business needs. An IANS faculty member, Pluralsight author and three-time DEF CON workshop speaker, he shares practical approaches to helping organizations reduce risk while continuing to build and grow.
