I’d say they are trying to further leverage the word Security.Rebranding an existing cert is risky at best. IT Project+ was rebranded Project+ to make it more inclusive of non-IT projects. CSA+ was rebranded CySA+, although I'm not sure why. I honestly don't see the value of rebranding CASP+ as SecurityX. And how will CloudNetX be that much different from Cloud+? How will DataX be significantly different from the existing Data+, DataSys+, and DataSci+?
In other news, I will be pursuing SecurityX next year
