Cybersecurity speaker Keren Elazari is a globally recognized authority on hacking, artificial intelligence, and digital resilience who makes 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 clear strategies for organizations navigating digital transformation, AI adoption, and an 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 certification, and serves as a senior researcher at Tel Aviv University’s Blavatnik Interdisciplinary Cyber Research Center. Beyond the stage, she founded BSidesTLV, Israel’s largest hacker community conference, and the global Leading Cyber Ladies network for women in cybersecurity. She co-authored the Amazon bestseller Women in Tech and supports the HackeRiot initiative, which opens cybersecurity career paths to women of all backgrounds. Her ongoing analysis appears at her personal site.
As a speaker, Keren Elazari brings a rare combination of deep technical expertise and mainstream storytelling. C-suite executives value her insights on AI-powered threats, digital warfare, organizational resilience, and innovation through the hacker mindset, frameworks that reach far beyond cybersecurity into competitive strategy, risk management, and leadership in an era of persistent digital disruption.
What do ethical hackers, elite founders, and the most innovative organizations share? They think like hackers, staying curious, challenging assumptions, and finding creative solutions to seemingly impossible problems. Drawing on 25 years in the hacker world, Keren reveals a framework for innovation, resilience, and competitive advantage that reaches far beyond cybersecurity. Leaders learn how hackers approach complex systems, surface hidden weaknesses, experiment without fear of failure, and turn constraints into opportunities, with practical tools for building cultures of curiosity and teams that thrive on hard problems.
Artificial intelligence is reshaping every industry while creating unprecedented security risks and new openings for malicious innovation. With a hacker's perspective, Keren examines AI's dual role as both shield and weapon in the disinformation age. She shows how attackers already weaponize AI, what organizations need to capture its upside while staying ahead of threats, and why traditional defenses fail against AI-powered adversaries. Audiences leave with practical guidance on protecting AI systems, detecting deepfakes and synthetic content, and building governance for an era where automation amplifies both innovation and risk.
Step into the sophisticated world of cybercriminal innovation, where threat actors evolve tactics and technologies that rival legitimate businesses. Keren exposes how criminal markets operate, from ransomware-as-a-service to the economic drivers fueling the cybercrime economy. By understanding adversaries' supply chains, business models, and innovation cycles, defenders can anticipate tomorrow's threats instead of merely reacting to today's. Leaders learn what makes cybercriminals effective, where their weaknesses lie, how to think like an attacker to strengthen defense, and which emerging threats demand attention across finance, healthcare, and critical infrastructure.
AI-powered threats, deepfake deception, and nation-state cyber operations are reshaping the security landscape, and cyber activity is now inseparable from geopolitics. Keren explores how nations deploy digital weapons, from Stuxnet to recent conflicts, what this means for businesses and citizens caught in the crossfire, and how organizations build resilience amid 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 strategic targets.
As AI reshapes every industry, trust has become the most valuable and most fragile currency in business. Drawing on her work advising Fortune 500 companies and governments, Keren explores what digital trust really means, how deepfakes and algorithmic bias erode it, and what leaders in finance, insurance, healthcare, and technology must do to earn and keep it. She addresses transparency in AI systems, accountability when algorithms fail, privacy in data-driven models, and security as the foundation of trust, equipping boards and C-suite audiences with practical frameworks for an age when technology mediates every customer interaction.
