| Why it matters | As part of the combined IDET/PYROS/ISET security fairs, ISET gives suppliers direct access to Czech and Central European public-sector, security-force and armed-force buyers alongside a major defence procurement audience. For SMEs and startups it is an export-oriented platform where cybersecurity and critical-infrastructure solutions can be demonstrated to decision-makers and international delegations in one place. | The fastest way for engineers and early founders to plug into the European defence-tech builder scene, meet operators and get noticed by funds active in the space. |
