Actoreon is a Brussels-based strategic advisory firm specialising in intelligence, economic security and influential communication — helping organisations understand their environment, protect their interests and shape their future.
Four imperatives. One integrated advisory practice.
Actoreon's advisory offer is built around three interconnected disciplines. Together, they provide clients with a complete picture — from intelligence and protection to positioning and influence.
We map the terrain before you move. Our intelligence practice transforms open-source data, human insight and analytical rigour into structured, decision-grade intelligence — giving you the strategic clarity to act with confidence.
We protect what you have built. From threat assessment and operational security consulting to economic intelligence and fraud prevention, we provide the structured safeguards that keep organisations resilient and their assets secure.
We help you be heard in the right rooms. Strategic narrative, public affairs and stakeholder engagement — crafted to shape perceptions, mobilise allies and deliver outcomes that extend well beyond a single conversation.
What distinguishes Actoreon is not a methodology or a framework. It is the quality of judgment — grounded in real operational experience, sustained by a trusted network, and delivered with absolute discretion.
Where law, finance, intelligence and security converge, Actoreon operates. Our leadership brings 25+ years of integrated expertise across the full spectrum of risk and strategy — from courtroom to boardroom, from compliance to operations.
We do not advise from a distance. Our experience spans NATO Headquarters, the European Commission, global security corporations and financial institutions — giving our advice a grounding in real-world complexity that consulting rarely achieves.
Based in Brussels — at the heart of European institutional life — Actoreon connects clients to a curated network of senior specialists across key geographies. We understand the European decision-making architecture from the inside.
In our field, trust is the foundation. We operate with complete confidentiality, professional integrity and a long-term view of every engagement. Our clients return not because we market ourselves — but because we deliver, and keep our word.
Actoreon was founded on a simple conviction: in today's complex environment, organisations need more than data. They need judgment.
The intelligence landscape is saturated with information. What is scarce — and what Actoreon provides — is the ability to synthesise that information into strategic insight, and to act on it with precision. We bring together senior professionals from intelligence, law, finance, security and communications to deliver integrated advisory services that are both analytically sound and operationally grounded.
We serve corporations navigating competitive or geopolitical risk, institutions protecting sensitive assets, and organisations seeking to shape their environment through strategic communication. Our engagements are bespoke, our methods are rigorous, and our commitment to our clients is unconditional.
Actoreon is deliberately structured as a boutique practice. This is not a limitation — it is a choice. It allows us to maintain the quality, focus and personal accountability that larger firms cannot offer.
Yannick De Smet brings over 25 years of multidisciplinary experience across law, finance, intelligence and security management. His career spans senior roles at NATO Headquarters, G4S Europe, Deloitte, the European Commission and the Belgian Ministry of Justice — combining strategic vision with deep operational expertise across complex international environments. Fluent in English, French and Dutch, he is a sought-after voice on security, intelligence and strategic risk.
Actoreon operates through a carefully curated network of senior specialists — former intelligence officers, legal and compliance experts, security professionals, financial analysts, and public affairs strategists. This model allows us to assemble the right team for each engagement, without the overhead or dilution that comes with large advisory structures.
Our collaborators share Actoreon’s commitment to discretion, intellectual rigour and operational excellence. They are not contractors — they are trusted partners, selected on the basis of track record and personal integrity.
This network gives Actoreon the versatility of a large firm with the responsiveness and accountability of a boutique.
Every engagement begins with a conversation. Whether you are navigating a specific challenge or exploring how strategic advisory can strengthen your organisation, we welcome the discussion — in confidence and without obligation.
