Best for: Multinationals with operations in multiple jurisdictions and complex ESG data requirements.
Overview: Diligent (formerly Accuvio) is a well-established ESG reporting platform known for its governance, risk, and compliance (GRC) capabilities. It's popular with company secretaries and compliance teams in Hong Kong.
Key strengths: Strong framework mapping (GRI, SASB, TCFD, HKEX ESG guide), automated data validation, excellent audit trail. The board-level reporting features are a standout — you can generate board-ready ESG dashboards directly.
