For more than 30 years, David Jacoby has been thinking like an attacker and working like a defender. He began in the underground hacking era, long before cybersecurity reached the boardroom. What started as curiosity: exploring systems, understanding weaknesses, pushing boundaries. It evolved into a lifelong mission: find the flaws before someone else does.
Over the decades, David has uncovered critical vulnerabilities, pioneered IoT hacking research, exposed large-scale scam operations, written security tools, and helped organizations understand how real attackers operate. He has advised multiple Fortune 500 companies, guiding executives and boards through the complex threat landscape. If there's a way in, he understands it. If it can be abused, he knows how, and how to stop it.
He has held senior leadership roles at multiple international security companies, founded Unbreached and the Threat Prevention Center, and today serves as Chief Strategy Officer at Syndis, driving strategy across offensive security, advanced SOC capabilities, and executive-level advisory.
An internationally award winning and recognized keynote speaker and author, David bridges hacker culture with executive clarity. He created and hosted his own TV show, HACKAD_, bringing ethical hacking to a broader audience, and served as trusted technical advisor to the Millennium series, ensuring even fictional hacks reflected reality.
Beyond business, he works closely with the World Childhood Foundation and is the global ambassador for HackShield, working to protect children online and inspire the next generation of ethical hackers.
From underground hacker to global security strategist. Curiosity with conscience, expertise with purpose, and offense in service of defense.
