Voice of an SME! One small company’s experience of ETSI

       Francois Ambrosini, of IBIT Ambrosini UG, talks about his Work in ETSI TC RRS and TC CYBER

        “I think it is appropriate to say that ETSI is among the most – if not the most – SME-friendly
        standardization organizations globally”
