I'm not an expert in cyber, but in most cases the response is led by individual allies. When a country has been subject to an attack, generally they lead the response and they can turn to allies for assistance. We have put in place the capacity to provide support to allies who request it. Some allies that don't have a cyber-defence capacity as robust as that of others can ask for assistance and receive it. That is now operational.
In many instances, the response has been nationally led, and that's entirely okay.
