Hello and welcome to Custom Sensitive Information Types in Microsoft 365. My name is Lee Mucciarone, and I'm a Microsoft 365 content creator for Cloud Academy. I have four years of IT experience working for Microsoft, with two years of specialized experience as a customer training specialist, training users on Microsoft tools. Within Microsoft Purview, we have the data classification solution, which enables organizations with sensitive information types to protect sensitive data held by the organization. 

Microsoft provides built-in sensitive information types organizations can use to protect this data. Information like, home addresses, credit card numbers, personal client information, and more can all be maintained and managed using these information types. But what about information specific to your organization that might not have an existing built-in sensitive information type? Within Microsoft Purview, organizations are empowered to create their own custom sensitive information types with tools like Exact Data Match Classification, keyword dictionaries, and document fingerprinting. And that's going to be the focus of today's course. 

It's important to note that this course does require a basic understanding of sensitive information types, and the key components as this course focuses on creating custom sensitive information types. If you are unfamiliar with the basics of sensitive information types, I have linked another course that goes over their core components and navigation of the data classification solution, where sensitive information types can be found down below. If you're familiar, then you should be all set, and we're ready to go. This course will be going over; how to create and manage custom sensitive information types, how to use the Exact Data Match classifier, how to implement document fingerprinting, and how to create and utilize a keyword dictionary. Now that we know what we'll be covering, let's jump right into it with creating our own custom sensitive information type.
