I'm happy to say that some new research by Jay Jacobs, Wade Baker, and myself is now available, thanks to the Global Cyber Alliance.
They asked us to look at the value of DNS security, such as when your DNS provider uses threat intel to block malicious sites. It's surprising how effective it is for a tool that's so easy to deploy. (Just point to a DNS server like 22.214.171.124).
The report is available from GCA's site: Learn About How DNS Security Can Mitigate One-Third of Cyber Incidents
