Keren Elazari is a globally recognized technology speaker and cybersecurity authority who bridges the worlds of hacking, artificial intelligence, and business leadership—making the hacker mindset accessible to boardrooms, governments, and global audiences. Featured on CNN and Netflix, profiled on the cover of Forbes Israel, and a contributing writer for WIRED UK and the Financial Times, she translates complex cyber threats into actionable strategies for organizations navigating digital transformation, AI adoption, and the evolving threat landscape.
In 2014, Keren became the first Israeli woman to speak on the main stage of the TED Conference. Her talk “Hackers: The Internet’s Immune System” has been viewed by millions, translated into 30 languages, and selected for TED’s Most Powerful Ideas—remaining one of the most-watched presentations on security and hacking. Named one of Forbes Israel’s 50 most influential women, she has since delivered hundreds of keynotes across six continents for organizations including Google, Deutsche Telekom, AXA, Mastercard, Allianz, SAP, and Cisco.
A veteran of Israeli Defense Forces intelligence—where she served for a decade including as a cybersecurity officer—Keren holds an MA in Security Studies, the CISSP international certification, and serves as senior researcher at Tel Aviv University’s Blavatnik Interdisciplinary Cyber Research Center. Her keynotes blend cutting-edge threat intelligence with insights on AI, digital trust, and the hacker mindset, turning technical complexity into frameworks that leaders across every industry can apply immediately.
Beyond the stage, Keren founded BSidesTLV, Israel’s largest hacker community conference, and the global Leading Cyber Ladies network for women in cybersecurity. She co-authored the Amazon bestselling book Women in Tech (Penguin Random House) and proudly supports the HackeRiot initiative to make cybersecurity career paths accessible to women of all backgrounds.
As a speaker, Keren Elazari brings rare combination of deep technical expertise and mainstream storytelling ability. C-suite executives value her insights on AI-powered threats, digital warfare, building organizational resilience, and fostering innovation through the hacker mindset—frameworks that apply far beyond cybersecurity to competitive strategy, risk management, and leadership in an era of persistent digital disruption.
What do ethical hackers, elite entrepreneurs, and the world's most innovative organizations have in common? They think like hackers—embracing curiosity, challenging assumptions, and finding creative solutions to impossible problems. Drawing on 25 years in the hacker world, Keren reveals a powerful framework for innovation, resilience, and competitive advantage that applies far beyond cybersecurity. Leaders learn how hackers approach complex systems, identify hidden vulnerabilities, experiment without fear of failure, and turn constraints into opportunities. This keynote equips executives with practical tools for fostering cultures of curiosity, rewarding unconventional thinking, and building teams that thrive on solving hard problems.
Artificial intelligence is transforming every industry—but also creating unprecedented security risks and opportunities for malicious innovation. With a hacker's lens, Keren explores AI's dual role as both defense and weapon in the disinformation age. She showcases how hackers are already leveraging AI for attacks, reveals the strategies organizations need to truly benefit from AI's potential while staying ahead of threats, and demonstrates why traditional security approaches fail against AI-powered adversaries. Audiences gain actionable insights on protecting AI systems, detecting deepfakes and synthetic content, building AI governance frameworks, and preparing for an era where automation amplifies both innovation and risk.
Step into the sophisticated world of cybercriminal innovation, where threat actors constantly evolve tactics and technologies that rival legitimate businesses. Keren exposes the inner workings of criminal markets, emerging attack techniques including ransomware-as-a-service, and economic drivers fueling the cybercrime economy. By understanding how adversaries operate—their supply chains, business models, and innovation cycles—defenders can anticipate tomorrow's threats rather than merely responding to today's. Leaders learn what makes cybercriminals successful, where their vulnerabilities lie, how to think like an attacker to improve defense, and which emerging threats demand immediate attention across finance, healthcare, and critical infrastructure.
AI-powered threats, deepfake deception, and nation-state cyber warfare are reshaping the security landscape. From Middle East battlefields to Eastern Europe's digital frontlines and Pacific tensions, cyber operations are now inseparable from geopolitics. Keren explores how nations leverage digital weapons—from Stuxnet to Ukraine to Taiwan Strait operations—what this means for businesses and citizens caught in the crossfire, and how organizations can build resilience in an era of persistent digital conflict. Executives gain frameworks for understanding geopolitical cyber risk, protecting critical infrastructure, navigating supply chain vulnerabilities, and preparing for scenarios where commercial systems become military targets.
As AI reshapes every industry, trust has become the most valuable—and most fragile—currency in business. Drawing on her experience advising Fortune 500 companies and governments, Keren explores what digital trust really means, how it's being undermined by deepfakes and algorithmic bias, and what leaders across finance, insurance, healthcare, and technology must do to earn and maintain it. She addresses transparency in AI systems, accountability when algorithms fail, privacy in data-driven business models, and security as foundation of trust. This keynote equips board-level audiences and C-suite executives with frameworks for trust-building in an age where technology mediates every customer interaction and breach of trust spreads instantly.
