I welcome back two of my favorite MSP leaders: Dawn Sizer and Brian Weiss. We start with a bang—ThreatLocker is officially sponsoring the livestream! Dawn, a long-time advocate, shares how ThreatLocker’s zero trust approach has changed the game for her clients, while Brian gives us a behind-the-scenes look at managing security policies and the benefits of the Cyber Hero program.

We dive into the realities of supporting clients during office moves, including my own adventure involving a missing internet line and a malfunctioning elevator. Dawn opens up about a frustrating VoIP outage and the challenges of vendor support, while Brian explains how his team handles after-hours emergencies and maintenance windows. We also touch on Microsoft’s ever-changing partner programs, Action1’s powerful upgrade features, and the importance of documentation and process for solo MSPs.
