Microsoft is bringing Python support to Excel. What security steps are you taking and how are you sleeping at night?

Getting a most commonly used and easly to learn language like python support into most widely used tool MS Excel is a welcome step as I see it. It will be a union of two most adopted technologies and should provide new integrations not seen before. As far as security is concerned, its the same as using any other Low-Code and No-Code platforms and should be ensured by terms and conditions by Microsoft. 

None, it is safer than VBA

In general this is good news as it will allow Python to be used directly within in Excel worksheets. Microsoft is assuring users that data will remain secure in the cloud, but the risk should be viewed in the same lens as other new and emerging software changes.
