BEST Core Banking System: sovereignty score and 8 European alternatives

BEST (Banking Efficiency Software Tool) is a core banking system from Best Vision Group for private, commercial and universal banks and asset managers. According to the vendor it covers back, middle and front office, including a data warehouse, and works multi-company and multi-currency, in real time and with straight-through processing. Parameterisation lets institutions adapt processes without changing source code. Modules such as the central information file (CIF), anti-money laundering (AML), internet banking and mobile banking can be combined. The group also offers outsourcing of IT and back-office processes, including through ASP or SaaS.

Best Vision Group is headquartered in Lugano, Switzerland. Switzerland is not an EU member but is an EFTA country with an EU adequacy decision for data protection. Where data is hosted for an outsourcing service is not stated on the website, so ask the vendor. No owner outside Switzerland has been identified. As a bank, fix in advance where processing takes place and which group entity is the contracting party.

Why digital sovereignty matters with BEST Core Banking System

BEST Core Banking System is headquartered in Switzerland and falls under Swiss law, including the revised Swiss data protection act. Switzerland is not an EU member, but the European Commission recognises its level of data protection as adequate. Its Swiss headquarters does not by itself bring it under US legislation such as the CLOUD Act.

BEST Core Banking System hosts data in Switzerland only. Switzerland is not part of the EU or the EEA, so the GDPR does not apply there directly; the European Commission does recognise Swiss data protection as adequate, so personal data can go there without extra safeguards. Our model therefore scores it between EU hosting and hosting outside Europe. If you require strictly EU hosting, take this into account.

BEST Core Banking System is closed source and hosted by the vendor. The encryption keys and the runtime sit with the vendor and switching requires data migration. Ask about bring-your-own-key, export options and open standards.

What this means for your organisation depends on your whole stack and context. The free assessment weighs BEST Core Banking System together with your other vendors and gives a total score, a heatmap and the main risk drivers.
