ABOUT SEALED
SEALED is a Belgian consultancy founded in 2005 by Sylvie Lacroix and Olivier Delos, two senior information security consultants specialised in digital identity, trust services and cryptography. We act as architects of your trust and identity services: from analysis and design to the organisation and follow-up of their implementation, including the drafting of RFPs and the selection of the most appropriate solution providers.
Our work today covers the eIDAS Regulation and its implementing acts, including EU Digital Identity Wallets and qualified trust services, the once-only technical system (OOTS) of the Single Digital Gateway, identity proofing, PKI and IT security risk management. We advise governments in Europe, Africa and the Middle East, EU institutions and agencies such as the European Commission and ENISA, and large enterprises, and we contribute actively to standardisation.
