Prioritising Microsoft Patch Tuesday August 2026

Microsoft Patch Tuesday August 2026 is one of those releases where the order matters more than the headline count. I would patch the exploited flaw first, then the network-facing RCEs, and only then worry about the tidier backlog.

Human-led AI-assisted pentesting and review limits

AI-assisted pentesting is useful in the boring middle, where it can sort noise, group candidates, and keep a large target set moving. The trouble starts when it sounds certain about nonsense, so I...
