What your team learns

Build security into the whole application.

Code, components, infrastructure, and processes. Learn how to secure them together so a vulnerability in one part doesn't compromise everything.

Prevent vulnerabilities

Choose technologies and development practices that remove the root causes of vulnerabilities. Back them up with layers of protection.

Contain a compromise

Limit what accounts and components can reach and do. Build trust boundaries that protect the rest of the application when one part is compromised.

Detect and respond

Make attacks visible. Use monitoring and automatic defenses to stop repeated abuse, and retain the evidence your team needs to respond.

Cloud and Git

Fix the cloud and Git setup too.

Practice in simulations of the cloud and Git consoles your team uses.
