We recently gathered with over 100 government, industry, and non-profit professionals to brainstorm and debate information sharing and safeguarding standards and frameworks at the Workshop for Information Sharing and Safeguarding Standards (WIS3). Below is a brief summary of some of the challenges and solutions that government and industry leaders discussed at WIS3. This is by no means comprehensive, though, and we plan to release more robust outlines of the challenges that our community faces and our plans for solutions soon.
