Begeer
Always at the forefront of emerging crises; from studying Middle Eastern studies to working in cybersecurity and misinformation, and now on the front line of generative AI risks. I help organisations understand what's coming before it arrives.
Work
Building safety infrastructure for the AI era
I'm a Trust & Safety leader with close to a decade of experience at the intersection of AI, policy, and cyber intelligence. Currently Head of Emerging Trends (interim) at Alice (formerly ActiveFence), I provide intelligence and partner with some of the world's most consequential AI and technology companies to provide them with intelligence on emerging threats, stress-test their systems and policies for safety and enforcement gaps.
My background spans cybersecurity, LLM safeguards, and building high-performance intelligence teams across multiple continents and time zones.
I hold an MSc in Crisis & Security Management from Leiden University, where my thesis on media-induced terrorism received a top grade, alongside a BA in International Studies (Distinction) and certifications in CompTIA Security+, Beginners Python, and Agile Management.
Expertise
What I bring
LLM Safeguards
Multimodal adversarial testing across text, image, and video to surface vulnerabilities in next-generation LLMs and AI systems before they reach the public.
Intelligence Leadership
Building and managing globally distributed teams across misinformation, hate speech, CSAM, Counter-Terrorism, and emerging GenAI threats; coordinating specialist expertise into unified, actionable intelligence.
Operational Efficiency
AI-assisted automation and workflow redesign that reduced headcount by 31% while maintaining delivery volume and quality standards.
Emerging Threats
A career-long track record of identifying and responding to new crisis vectors; from cyber and misinformation to generative AI risks.
Beyond Work
Outside the office
Tag Rugby
I play every week; it's one of the few things that completely empties my head. There's something irreplaceable about the focus and camaraderie of team sport.
Travel
I travel regularly, whether back to family in the Netherlands or somewhere entirely new. Exploring different cultures, languages, and cuisines is a constant source of curiosity.
Cycling
Currently training for a Rotterdam to Paris ride in April; combining two of my favourite things: endurance exercise and arriving somewhere interesting at the end of it.
Cooking
A few uninterrupted hours in the kitchen is my version of therapy. Experimenting with new cuisines, mostly inspired by wherever I've recently been.
Reading & Book Club
I go to a book club once a month, it's reliably made me read books I'd never have chosen myself, which is exactly the point.
London
I've lived here since 2017 and it still surprises me. There's always a neighbourhood I haven't properly explored yet.
