Viginum's Chief Marc-Antoine Brillant Leaves to Launch a 'Counter-Interference' Agency With Havas
Marc-Antoine Brillant, head of France's foreign-interference watchdog Viginum, is leaving the public sector to co-found an information-security 'counter-interference' agency with Havas — about seven months before the French presidential election.
A High-Profile Public-to-Private Move
Brillant, who leads Viginum — the French state service tasked with detecting and countering foreign digital interference — is leaving to launch a new venture with Havas, described as a counter-interference agency. The move was reported on 3 September, roughly seven months out from the presidential election.
It's a striking crossover: one of the state's most senior figures on disinformation defence moving into the private communications world, and taking that expertise into an agency setting.
Why Havas Is Buying Into This
For a major agency group, standing up a counter-interference and information-security offer is a bet that brands, institutions and possibly political actors will pay to defend their reputations against coordinated disinformation and manipulation.
It sits at a sensitive but fast-growing intersection of communications, cyber and security. As trust becomes a board-level risk, 'protecting the information space around your brand' is an increasingly credible line of business for agencies to sell.
The Sensitivities Marketers Should Note
The timing — months before a national election — and the public-sector provenance will invite scrutiny about the line between state expertise and private interests. That is precisely the kind of perception risk a disinformation-defence business must itself manage flawlessly.
For brands, it's a reminder that reputation is now contested in an information environment shaped by coordinated actors, bots and AI-generated content. Brand safety has quietly expanded from 'don't appear next to bad content' to 'defend against active manipulation.'
Marketing Minute's Read
The rise of counter-interference offers signals where communications is heading: protecting the information space around a brand is becoming as important as the messages a brand puts into it. Defence, not just projection.
Businesses should at minimum know how they'd detect and respond to a coordinated disinformation attack on their brand. You don't need to buy an agency for it today, but you do need a plan before you need one.

Brand safety used to mean 'don't sit next to bad content' — now it means defending against active, coordinated manipulation. Every business should at least know how it would respond. — Daniel Nikolla, Founder of Merx Marketing
The takeaway: brand safety has expanded from avoiding bad adjacency to actively defending against coordinated disinformation — every business should have a plan to detect and respond before it needs one.
Should defending against disinformation be part of every brand's marketing plan now — or is it still a niche concern?
