The American Academy of Actuaries’ Cyber Risk Toolkit, developed by the Academy’s Cyber Risk Task Force, is comprised of a series of papers addressing issues pertinent to cyber risk insurance and cyber exposure. This toolkit is intended to be a resource for interested readers of the general public, public policymakers, the actuarial profession, the insurance sector, and other stakeholders. Cyber risk issues have been in the news regularly recently, and those using the toolkit can benefit from the perspectives offered in the papers.
