At Microsoft, we analyze 300 billion user authentications and check 200 billion emails for spam and malware monthly. We also have unprecedented visibility into cloud infrastructure choices, platforms and the activity therein. Microsoft can take advantage of its vast global threat intelligence and security expertise to develop highly tuned models using a wealth of analyzed examples. Machine Learning helps us automatically determine the right X a given resource should tolerate, without developing custom analysis for each individual resource. We use Machine Learning to enable customers to benefit from the wisdom of other organizations when making security decisions.”]
