## Resource

Episode 44 of Cloud Computing with Fexingo unpacks a subtle but costly shift in how AWS, Azure, and GCP handle firewall rules. Lucas and Luna explore why default security group configurations now allow more outbound traffic by default, how a mid-size SaaS company saw its monthly data transfer costs jump 23% after a routine security update, and what teams should check before the next quarterly review. They break down the specific policy changes each provider has made in the past six months—AWS's new VPC reachability analyzer defaults, Azure's expanded service tag coverage, and GCP's firewall rule logging changes—and explain why ignoring these defaults can lead to surprise egress charges. The episode also covers practical next steps: auditing existing rules weekly, tightening default deny policies, and using third-party tools like Fugue or Wiz to continuously validate firewall posture. A must-listen for any engineering or finance team managing cloud costs. #CloudSecurity #FirewallPolicy #AWS #Azure #GCP #DataEgress #CloudCosts #NetworkSecurity #VPC #SecurityGroups #CloudGovernance #TechPodcast #FexingoBusiness #BusinessPodcast #SaaS #FinOps #CloudInfrastructure #Episode44 Keep every episode free: buymeacoffee.com/fexingo
