๐Ÿ”” Your essential security briefing is here! This week, Matt Warner, Nick Dixon, and Jake Ouellette join Zoe Lindsey to break down critical developments in cybersecurity with practical context for busy IT and security teams. ๐Ÿ””

What We Cover This Week: 

๐Ÿ” Trend Micro patches 6 critical vulnerabilities (CVSS 9.8) in Apex Central and PolicyServer products - and how the deserialization method leveraged to exploit them works

๐Ÿ” Over 80,000 Microsoft Entra ID accounts targeted using TeamFiltration - how this pen testing tool is being weaponized by attackers 

๐Ÿ“˜ NIST's new Zero Trust Implementation Guide - less conceptual introductions, with better focus on practical implementation

๐Ÿ“ŠLatest World Economic Forum report shows smaller organizations feel they are approaching cybersecurity breaking point - the panel talks how to get strategic when resources and time are tight

๐Ÿ’ก Quick tip of the week: Perform a gap assessment to identify high-impact, low-effort security improvements to prioritize first โ€” evolution, not reinvention is the name of the game!


Plus, Expert Insights On:
