Why it matters
SecD-Day has rapidly become the largest defence and security exhibition ever held in Finland and a key Nordic meeting point, offering direct access to Finnish and international primes, authorities and foreign delegations following Finland's NATO accession. For SMEs and startups it provides a comparatively affordable route to reach national armaments buyers, strategic partners like Patria and Millog, and international primes in a growing Northern European defence market.
