Open-source cybersecurity tools and applications can contribute to a higher degree of openness and can have a positive impact on the efficiency of industrial innovation. Open standards facilitate interoperability between security tools, benefitting the security of industrial stakeholders. Open-source cybersecurity tools and applications can leverage the wider developer community, enabling diversification of suppliers. Open source can lead to a more transparent verification process of cybersecurity related tools and a community-driven process of discovering vulnerabilities. Member States should therefore be able to promote the use of open-source software and open standards by pursuing policies relating to the use of open data and open-source as part of security through transparency. Policies promoting the introduction and sustainable use of open-source cybersecurity tools are of particular importance for small and medium-sized enterprises facing significant costs for implementation, which could be minimised by reducing the need for specific applications or tools.
