SISO TEAM: sovereignty score and 8 European alternatives

SISO TEAM is an online platform for project collaboration and information management in construction projects, part of the SISO Project Governance solutions. It replaces many cross-posted e-mails with information recorded directly against each event or action, organises documents and data of different kinds in one structure and mirrors the project organisation. Simple workflows, such as quality controls, support business processes like the quality manual, drawing management and the print service. Only the people concerned get online access. According to the vendor, SISO TEAM also underlies SISO TUNNEL, a module for tunnelling projects.

SISO TEAM is developed by SISO SA, headquartered in Bellinzona, Switzerland. Switzerland is not an EU member state, but it is an EFTA country with an adequacy decision from the European Commission. According to the vendor, SISO SA is wholly owned by a holding company; the country of that holding is not stated. The vendor does not state where data is hosted or how the product is delivered, so ask about hosting and a data processing agreement before you decide.

Why digital sovereignty matters with SISO TEAM

SISO TEAM 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.

SISO TEAM 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.

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