Agents are AI systems that can perform workflows on users' behalf with a high degree of independence. This guide, designed for product and engineering teams, explores how to build agents with frameworks for identifying promise use cases, clear patterns for designing agent logic and orchestration, and best practices to ensure agents run safely, predictably, and effectively. It provides the foundational knowledge needed to confidently start building agents. Building reliable agents means starting with strong foundations - start small, validate with real users, and grow capabilities over time.

As per the NIS2 Directive, ENISA is mandated to develop and maintain the European vulnerability database.
Access to reliable and timely information about vulnerabilities affecting Information and Communication Technology (ICT) products and services contributes to an enhanced cybersecurity risk management. Sources of publicly available information about vulnerabilities are an important tool for users of these services, competent authorities, and the broader cybersecurity community. ENISA has established a European Vulnerability Database (EUVD) where entities, regardless of whether they fall within the scope of the NIS2 Directive, and their suppliers of network and information systems, as well as competent authorities, most notably CSIRTs, can voluntarily disclose and register publicly known vulnerabilities to allow users to take appropriate mitigating measures.
