With over two decades of experience in cybersecurity and public service, I am passionate about creating a safer and more secure digital world for everyone.
I run my own security consulting firm, Joe Sullivan Security LLC, where I help companies develop security best practices, advise security startups on product and market opportunities, and mentor executives.
Previously, I served as the Chief Security Officer at Cloudflare, Uber, and Facebook, where I oversaw the protection of billions of users and their data.
I also have a background as a former federal prosecutor and a commissioner for the bipartisan Obama Cyber Commission.
Additionally, I volunteer for nonprofit safety and security organizations, advise startups, and invest in promising ventures.
