Frequently Asked Questions

What is SPIFFE?

SPIFFE (Secure Production Identity Framework For Everyone) is a CNCF standard that defines how workloads identify themselves to each other using cryptographic certificates, independent of network location.

What is SPIRE?

SPIRE (SPIFFE Runtime Environment) is the production implementation of SPIFFE. It automatically issues, rotates, and manages cryptographic identities for every workload in your infrastructure.

Is this course really free?

Yes, 100% free. 13 modules, 30+ hands-on labs, all course content, and the companion GitHub repository are completely free with no paywalls or upsells.

Who is this course for?

Platform engineers, DevOps engineers, security engineers, SREs, Kubernetes engineers, and backend developers who want to learn production-grade workload identity and Zero Trust security.

Do I need prior SPIFFE experience?

No. The course starts from Zero Trust fundamentals and builds up to production SPIRE deployments, federation, and AI infrastructure security.

What is workload identity?

Workload identity gives every service, container, or process a unique cryptographic identity — like a passport for machines. It replaces shared secrets, API keys, and IP-based trust with automatic, short-lived certificates.

How does SPIFFE compare to HashiCorp Vault?

SPIFFE provides workload identity (who is this service?). Vault provides secret management (what secrets can it access?). They are complementary — workloads can authenticate to Vault using their SPIFFE SVID instead of static Vault tokens.

What is Zero Trust?

Zero Trust is a security architecture that requires cryptographic verification of every request, regardless of network location. It replaces the traditional perimeter model where everything inside the network is trusted.
