The NOTIONES project’s objective has been to build a network of practitioners from security and intelligence services of EU Member States and associated countries. The network supports the needs of security and intelligence services and equips them to participate in research and/or innovation actions. The project has brought together practitioners from military, civil, financial, judiciary, local, national and international police authorities. As the project approaches its completion, the fifth and final NOTIONES conference draws together innovative research, case studies, and technical demonstrations. The event shares best practices in making security and intelligence practitioners work together with academia and industry. Rapid technological change and advances in the applying technologies to the everyday work of security practitioners are broken down into shareable knowledge for the benefit of maintaining secure, adaptive, and resilient societies. The conference offers research and practitioner knowledge from the NOTIONES network, other EU projects in the field, and invites participants to share recent findings and new insights. For the conference, presentations are invited on ongoing and recently concluded research, practitioner cases, novel use of relevant technologies and analyses of changing law and governance in the field.
