The Secure Information Exchange Network Application (SIENA) enables the swift and secure exchange of operational and strategic crime-related information and intelligence between EU Member States, Europol and cooperating third parties.
The Large File Exchange (LFE) solution enables the secure exchange of files that exceed the size limit (50MB) of the Europol Secure Information Exchange Network Application (SIENA) when the need arises (for example sending an image of a hard drive or copy of a server).
In 2015, Europol continued to roll-out SIENA to specialised and regional units, including counter terrorism units in the Member States and partners having operational agreements with Europol. The number of counter terrorism units with access to SIENA has more than doubled since the beginning of 2015. More than 30 counter terrorism units now have access to SIENA. A number of changes have been made to adapt SIENA to the requirements of counter terrorism units to exchange information bilaterally.
The efforts to develop SIENA as the default secure communi- cation tool for counter terrorism units will continue in 2016, with an upgrade to allow the handling of EU confidential information (for sensitive information exchange, such as CT, anti-corruption etc.) and with the roll-out of SIENA for additional counter terrorism units from Member States and partners having operational agreements with Europol.
