Recital 34

(34)

Financial entities should be encouraged to exchange among themselves cyber threat information and intelligence, and to collectively leverage their individual knowledge and practical experience at strategic, tactical and operational levels with a view to enhancing their capabilities to adequately assess, monitor, defend against, and respond to cyber threats, by participating in information sharing arrangements. It is therefore necessary to enable the emergence at Union level of mechanisms for voluntary information-sharing arrangements which, when conducted in trusted environments, would help the community of the financial industry to prevent and collectively respond to cyber threats by quickly limiting the spread of ICT risk and impeding potential contagion throughout the financial channels. Those mechanisms should comply with the applicable competition law rules of the Union set out in the Communication from the Commission of 14 January 2011 entitled ‘Guidelines on the applicability of Article 101 of the Treaty on the Functioning of the European Union to horizontal cooperation agreements’, as well as with Union data protection rules, in particular Regulation (EU) 2016/679 of the European Parliament and of the Council (13). They should operate based on the use of one or more of the legal bases that are laid down in Article 6 of that Regulation, such as in the context of the processing of personal data that is necessary for the purposes of the legitimate interest pursued by the controller or by a third party, as referred to in Article 6(1), point (f), of that Regulation, as well as in the context of the processing of personal data necessary for compliance with a legal obligation to which the controller is subject, necessary for the performance of a task carried out in the public interest or in the exercise of official authority vested in the controller, as referred to in Article 6(1), points (c) and (e), respectively, of that Regulation.
