I used to work for a now defunct Swiss company that had “Swiss quality, security and privacy” plastered all over the website and marketing materials. The number of actual Swiss people on the team could be counted on one hand, the rest of developers being from every European country out there, with the most represented ones being Ukraine and Romania. And from talking with my coworkers, the situation is the same across other Swiss IT companies.
I would not pay any attention to the “Swiss X” marketing.
