On 9 October 2025, the European Investment Bank (EIB) joined the Secure Information Exchange Network Application (SIENA) operated by Europol. With 3500 connections, SIENA is the EU’s main channel for swiftly and securely exchanging sensitive and restricted information between European law enforcement authorities, European agencies and bodies (such as Eurojust, the EPPO, and OLAF), and trusted partners outside the EU. By joining the network, the EIB will be able to use the platform to safely and promptly exchange information with the relevant authorities. This accession adds to the working arrangement signed between Europol and the EIB in 2001.
