Securing the Workspace Attackers Already Live In with Rajan Kapoor

Your email gateway isn't enough anymore, attackers are already inside the workspace through OAuth apps, browser extensions, and account takeover.

In this episode, Ron sits down with Rajan Kapoor, VP of Security at Material Security, to break down the real risks hiding inside Google Workspace and Microsoft 365. They cover how phishing has evolved into full-blown business email compromise, why malicious OAuth apps are the new favorite attack vector, and what security teams, especially lean ones, can do right now to lock down their cloud workspace. Rajan also drops practical advice on passkeys, document sharing hygiene, and why data lifecycle management is a problem no one is solving well enough.
