This was an interesting find https://s1.nordcdn.com/nord/misc/0.13.0/vpn/brand/NordVPN-cyber-risk-index-2020.pdf via https://nordvpn.com/cri/ but it’s a Statista thing so … unsure.
More indices are here: https://www.trendmicro.com/en_us/security-intelligence/breaking-news/cyber-risk-index.html
Chubb cyberindex https://chubbcyberindex.com/#/incident-growth is nice in how it lays out the changes over time. They have a nice cyber risk incident cost calculator too: https://chubbcyberindex.com/#/cyber-risk-calculators
ITU has a series of cybersecurity indices covered for the past few years: https://www.itu.int/en/ITU-D/Cybersecurity/Pages/global-cybersecurity-index.aspx and the new one should be coming out this year.
