On the 12th of May 2022, SENTINEL organized a joint clustering webinar with projects funded under the H2020-SU-DS02 and H2020-SU-DS03 topics to explore possible collaborations between EU-funded projects relevant to Cybersecurity, Personal data protection and GDPR compliance topics. More than 25 participants from PALANTIR, TRAPEZE, PUZZLE, CyberKit4SME, ARCADIAN-IoT, IRIS, ERATOSTHENES, IDUNN, and SECANT projects joined the event. It was a really brainstorming webinar with fruitful and constructive discussions from all the participants.
