A short, pronounceable .si domain for defence, dual-use technology and brands that sit at the intersection of SI = Slovenia and SI = Super Intelligence.
DEF = defence / defense.
SI = Slovenia and Super Intelligence.
It reads as a company, fund, product or defence-tech brand — not a sentence you have to explain.
.si is Slovenia’s country domain and is also being used as a Super Intelligence suffix. A clean 5-letter name on .si is scarce and useful for European buyers.
Suppliers, dual-use manufacturers, drones, C-UAS, electronics and defence IT. A short EU-facing B2B name.
Startups and funds linking AI, sensors and security. SI as Super Intelligence, not only a country code.
A landing for tenders, news, an association or a Slovenian / European defence-tech network.
