AWS Multi-Account Security: What Netflix Learned

🚀 How do you secure thousands of AWS accounts without slowing down developers? Netflix’s cloud security experts Patrick Sanders & Joseph Kjar join us to break down their identity-first security model and share lessons from scaling security across a massive AWS multi-account environment.

In this episode, we cover:

Why identity, not network, is the best security boundary
The challenges of least privilege and right-sized access
How Netflix migrates IAM roles while minimizing disruptions
The impact of multi-account AWS security strategies
