The 14 May 2025 Supervision Newsletter article 'Benefits from advanced technology infrastructure in supervision' catalogues the ECB's suptech stack: Heimdall (machine reading for fit-and-proper files, cutting processing from 109 days in 2023 to 97 in 2024), Athena (NLP, translation and generative-AI text review across supervisory documents), Agora (unified prudential data lake), Delphi (news-based market monitoring), Navi (network analytics) and more than 100 robotic process automations running up to 15 times faster than manual work. Project Olympus aims to integrate these into a single supervisory cockpit with AI-enhanced search.

## Key points

- Heimdall: machine reading of fit-and-proper questionnaires; average processing fell from 109 days (2023) to 97 days (2024)
- Athena: natural-language processing, translation and generative-AI-assisted review of supervisory documents with visible sources
- Agora: consolidated prudential data infrastructure across the ECB and national competent authorities
- Delphi: news-based market-behaviour monitoring, with social-media alerts planned; Navi: graph analytics for ownership structures and NBFI exposures
- Over 100 RPAs deployed, completing tasks up to 15 times faster than manual processing
- IMAS Portal (2020), CASPER (2022) and STAR (2017) handle bank submissions, ad hoc data collections and stress-test data
- Project Olympus: single supervisory cockpit and AI-enhanced search across European banking supervision

## What changed for banks

Banks now know that their filings — fit-and-proper questionnaires, ad hoc data, narrative reports — are machine-read and cross-checked by AI before a supervisor sees them, which raises the bar for consistency across submissions and across languages.
