The NATO Communications and Information Agency (NCIA) is seeking information from industry partners regarding capabilities to support the issuance of publicly trusted certificates for document signing, email signing, and Transport Layer Security (TLS). This Request for Information (RFI), designated RFI-424314-NPKI-TPT, aims to gather insights on potential solutions for qualified electronic signatures under EU eIDAS regulations, as well as public-facing TLS certificates and client authentication certificates for enterprise use. The information collected will assist NCIA in understanding the marketplace and developing future acquisition strategies, with responses due by 12:00 hours CET on January 5, 2026. Interested vendors from NATO member countries should submit their responses directly to the designated RFI Point of Contact, as submissions to the Department of Commerce will not be accepted.
