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.
Speaker engagements
Selected highlights
Keynote presentation at the Trust & Safety Professionals Association EMEA Summit, examining how AI-generated imagery is being operationalised in modern misinformation campaigns.
Invited to brief government staff on identifying and responding to disinformation and misinformation, supporting the UK's national security intelligence community.

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.
