What the act provides
If the minister concerned considers it necessary to manage risks to the security of network and information systems that affect national security, or to prevent incidents that affect national security, he imposes on an essential or important entity the obligation to use, in the designated parts of its network and information systems, only products or services from parties other than the party he names [1]. He does so in agreement with the Minister of Justice and Security [1] [6].
Which suppliers are concerned
The named party is a state, entity or person known or suspected to want to compromise the security of your systems or to cause incidents at your organisation. It can also be a party with close ties to or under the influence of such a state, entity or person, or a party where there are grounds to suspect such ties or such influence [1].
Other measures first
In assessing whether the obligation is necessary, the minister in any case assesses whether control measures are possible and feasible that offer sufficient protection against the risks to national security [2].
What you already use
If the obligation concerns products or services you already use, the minister sets a period for replacing or terminating them, in the interest of the continuity of your service provision [3]. This article does not apply to providers of public electronic communications networks or services [4].
Fine
The same fine maximum applies to an infringement as for the duty of care and the reporting duty: for an essential entity at most 10 million euros or 2% of the undertaking's worldwide annual turnover, whichever is higher [5], for an important entity at most 7 million euros or 1.4% [7].
What you do now
Your supply chain policy already records which supplier products and services your systems depend on [8]. With that overview you can quickly see which parts such an obligation would affect.
