Scaling AppSec at Netflix with Cosmos Microservices

Netflix launches new microservices daily. Not weekly. Daily.

When your architecture is thousands of services deep and growing at that pace, you can’t secure it with manual reviews and quarterly audits. You just can’t. The only viable strategy is automation plus queryable data, and Netflix’s engineering team has written openly about how they’ve built exactly that.

Their Scaling AppSec blog post lays out an approach that I think any engineering leader running a microservices architecture should study — not to copy Netflix’s specific tooling, but to understand the organizational model behind it.
