Harvest O2S: sovereignty score and 8 European alternatives

O2S is the CRM for wealth advisers from Harvest France. Advisers manage their clients in one tool, from onboarding to management acts. O2S aggregates clients' account positions, supports compliance across the regulatory journey (DDA, MiFID II, anti-money-laundering rules and the obligations of the CIF status), analyses portfolios on performance, diversification and style, and sends automatic alerts. Electronic signature and document management are built in; the O2S Success offer adds APIs, extra storage space and single sign-on.

Harvest France SAS has its registered office in Paris and belongs to the Harvest group. According to the group page, Harvest aims to deliver its whole range as cloud/SaaS and through APIs. The data protection charter says the personal data it processes is not transferred outside the European Union. The product page names no parent company, hosting party or delivery model for O2S. Ask for these details and document them in the data processing agreement.

Why digital sovereignty matters with Harvest O2S

Harvest O2S is headquartered in France and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data.

Data is hosted exclusively in the EU, so Harvest O2S scores best on data residency.

Harvest O2S 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 Harvest O2S together with your other vendors and gives a total score, a heatmap and the main risk drivers.
