FES Scores 9
Pillar Criterion Score Evidence
Easy Day-one UX Can non-technical staff use it without a project? 3 SQL standard (ISO/IEC 9075) is widely adopted and documented, enabling day-one deployment for basic operations. Source
Easy Operate Admin burden, updates, backups and language coverage. 2 Rule baseline (rubric_v1): self-host usually means patching, backups and upgrades for the NGO. Source
Easy Integrate SSO, mail/CalDAV, APIs and common NGO connectors. 5 SQL is a universal standard for database integration, supported by nearly all relational database systems. Source
Fair Lock-in / exit Can you leave with your data in open formats, at known cost? 4 Rule baseline (rubric_v1): self-host helps exit; proprietary product may still constrain formats. Source
Fair Sovereignty EU legal entity, EU hosting, and exposure to extra-EU lawful access? 4 Rule baseline (rubric_v1): non-EU vendor; self-host still lets you pick EU infra — verify update/support exposure. Source
Fair Openness Open source or open standards? Are independent implementations possible? 2 Rule baseline (rubric_v1): proprietary / non-OSI license — openness capped unless open standards dominate. Source
Secure IT security Authentication, encryption, patch cadence and independent audit. 3 SQL standard includes security features like access control and data integrity but requires implementation by vendors. Source
Secure User security 2FA, roles, phishing resistance and safe defaults. 2 SQL standard itself does not enforce user-level security; this depends on the specific database implementation. Source
Secure Personal data GDPR fit: DPA, residency, sub-processors and Schrems II posture. 4 SQL standard supports structured storage and querying of personal data, enabling compliance with data protection frameworks. Source
