Chema Alonso biography
With his trademark striped beanie and a gift for making the most complex threats feel urgent and understandable, Chema Alonso (José María Alonso Cebrián) has become the most recognizable face of cybersecurity in the Spanish-speaking world. A hacker, computer-security researcher, and technology executive, he has spent his career on the front lines of the digital world, breaking systems to make them safer, and translating the fast-moving realities of hacking, data, and AI for audiences from corporate boardrooms to prime-time television.
Cybersecurity speaker Chema Alonso holds a PhD in computer security and first made his name as an ethical hacker and researcher, creating widely used tools such as the FOCA metadata analyzer and the Latch security app. In 1999 he founded the consultancy Informática 64, which was later acquired by Telefónica and became ElevenPaths, the telecom giant’s cybersecurity unit, which he led. For over a decade he sat on Telefónica’s executive committee as Chief Data and Chief Digital Officer, steering major initiatives in artificial intelligence, Big Data, and security.
From ElevenPaths to Cloudflare
In 2025, Alonso took on a new global challenge, joining Cloudflare as Vice President and Head of International Development, where he drives the company’s worldwide expansion with a particular focus on Europe and Latin America. One of the most influential technologists in Spain, he was named to Forbes’ list of the world’s most influential CMOs and received Spain’s Civil Guard Cross of Merit. Through his hugely popular blog El Lado del Mal and his constant public presence, he has done more than almost anyone to raise cybersecurity awareness among the general public.
As a speaker, Chema Alonso is magnetic, funny, and genuinely eye-opening, often live-demonstrating how attacks really work and why they matter. He speaks on cybersecurity and the evolving threat landscape, ethical hacking, artificial intelligence and its risks, data and privacy, and digital transformation. Whether he is addressing technical experts or a general business audience, he leaves people newly aware of the digital dangers around them, and better equipped to face a future defined by AI and constant connectivity.

Chema Alonso Keynote Topics
Drawing on decades on the front lines, from ethical hacking to leading cybersecurity at one of the world's largest telecoms, Chema Alonso gives audiences a clear, gripping picture of the threats facing organizations today. He shows, often with live demonstrations, how attackers actually operate, why traditional defenses fall short, and what leaders and organizations must do to protect their people, their data, and their future in an increasingly hostile digital world.
The best way to defend a system is to understand how it breaks. In this eye-opening keynote, Alonso pulls back the curtain on the mindset and methods of hackers, revealing how vulnerabilities are found and exploited and how the same skills can be used to protect rather than attack. Entertaining and unsettling in equal measure, it leaves audiences with a genuine, practical understanding of security they can apply immediately.
AI is transforming every industry, but it also introduces powerful new risks, from AI-enabled attacks to the security flaws built into AI systems themselves. Alonso, who has led AI and Big Data initiatives at scale, cuts through the hype to explain what AI really means for security, how criminals are already weaponizing it, and how organizations can harness its power while protecting themselves against a new generation of threats.
Everyone is a target, and most people have no idea how exposed they are. In this accessible, engaging talk aimed at general and business audiences, Alonso reveals how cybercriminals steal identities, money, and data, often without ever needing a password, and shares practical, memorable steps that individuals and organizations can take to protect themselves. A wake-up call that turns fear into genuine, actionable awareness.
