As enterprises shift to modern, cloud-native application development, they need an effective way to enable developers and development teams on the technology. The enablement has to scale across the enterprise, across multiple lines of business where developers work, as well as across geographic boundaries where they reside. It also has to support exploration, given that developers are often motivated by curiosity.

Security technical implementation guides (STIGs) provide a standardized set of security protocols for practically any system. From networks to servers and computers, STIGs are designed to enhance overall security and reduce vulnerabilities. But what happens when the guidelines vary across an enterprise?
