AI is changing the way we protect our computers from hackers, so security teams need to use AI-based defenses. Leslie Nielsen, Mimecast's CISO, talks about a crawl-walk-run method. When people and AI work together, shadow AI is a big threat.

A lot of companies don't keep an eye on AI tools that aren't allowed in their environments. He stresses that "the unknown risk is the greatest risk." He says that "visible first, visibility later" is the key to AI-powered defense. Nielsen says that Mimecast's Mihra investigation agent is very important for making this visibility-first approach work.

You can buy the MihRA investigation agent for $1,000 on the company's website. You can use it to look into things in the US, Europe, and Asia.
