Yes, SIB is a legitimate broker regulated by CySEC, making it a reliable choice for traders and investors in Cyprus and the broader EU market. The firm offers various investment services, including order execution, investment advice, and underwriting. However, as a Market Maker, SIB could face potential conflicts of interest, which might affect traders looking for a non-conflicted environment. I feel that, while regulated, it is important to understand the specific model the broker operates under before committing. The sib review suggests that the broker offers solid services, especially for those focused on Cypriot and European markets.
