02x07-b2c_you_later.auth

In this episode: Koos recently had to help a customer getting their Entra ID External ID connected to the SOC and discovered that it wasn't as straightforward as you might think. Let's revisit what Entra ID External ID is in the first place, and how it differs from the former B2C it replaced. Chris talks about why it's never been more important to patch your stuff and digs into the relationship between patch management and vulnerability management.

02x06-silence_of_the_logs.kql

In this episode Chris takes a look at Exchange-attribute Source of Authority (SOA) transfer - could this finally be the answer to removing that last Exchange server we've all been waiting for? Koos has spent years deep in Microsoft Sentinel, and a big chunk of that has been log ingestion and keeping the ingestion bill under control: getting the right data in, keeping the noise out. He promised this wouldn't turn into the Sentinel show, but when Microsoft ships two genuinely new log-ingestion features, he has to talk about them. There are two Azure Monitor previews worth talking about. The first, 'multi-stage transformations', lets you filter and aggregate logs before they're ingested. The second brings platform logs into the Data Collection Rule model, the same way he already collects everything else. He'll cover what's genuinely new, and why he thinks Microsoft perhaps highlighted the wrong features in their blogs.

02x05-maester_of_puppets.ps1

Live and face-to-face again, this time recorded from Experts Live Netherlands. Chris previews his EL:NL session on practical SecOps for Microsoft 365: how to automate the boring-but-critical parts of M365 security operations, continuously assess tenant posture, detect configuration drift, and respond to common issues using native Microsoft tools you already own. Koos recently went on a hunt for a compact FIDO2 security key and discovered there are a lot more options out there than you'd think. He'll walk through what he found, what the trade-offs are between form factor, protocols, and price, and which keys ended up making the shortlist.

02x02_you_shall_not_pass.key

In this episode, Chris take a look at PowerShell modules and how managing M365 and Entra ID has changed over the years. And Koos likes to re-visit Passkeys. This is not new and we covered it earlier in our very first episode in December of 2024. But quite a few things have changed since then and he believes now is the time to start onboarding at scale.

02x04-terminal_velocity.tui

In this episode Chris covers some common Intune deployment mistakes he's come across while working with various customer environments. Koos has become a full-time Claude (Code) user over the past months and wants to share why he's blown away. A few real-world stories where an AI agent saved the day. Or actually MULTIPLE days worth of work. ;). There's been a lot of talk lately about different models and multiple AI services seem to have been offering multiple different models to pick from. And even then; the same model can feel completely different depending on which "harness" it runs inside. Koos will explain what that is and why the right harness for the work you do matters more than the model sitting underneath it.
