Which experts can corporate directors follow to stay current on cyber-risks

I was trying to identify a few sources of relevant information to keep up to date with the rapid pace of evolution of cyber-risks, and found this list of experts. Most of the people proposed take a technical approach to cyber-risks as opposed to a governance approach. But if you take the time to read some of what they publish, you can identify a few that are a source of information adapted to your needs and that can help you stay current on cyber-threats and what is being discussed across industries. Important to support your oversight responsibilities. Do you have other sources to propose, maybe some Canadian ones?
