9 focused modules take you from foundational principles to secure design, defensive coding, security testing, DevSecOps pipelines, vulnerability management, and modern software delivery.
Rigorous, practitioner-level grounding in risk language, security objectives, and trust boundaries, applied to ambiguous real-world engineering decisions.
Turn security requirements into resilient systems before the first line of code is written, at the depth expected of a senior architect.
Repair realistic, multi-layered vulnerabilities with production-grade patterns for validation, authentication, and data handling.
Integrate SAST, dependency scanning, and hands-on security testing into your delivery pipeline.
A complete application-security course for Node.js, browser JavaScript, and Java based on modules.md.
Use coding assistants and autonomous agents without surrendering security judgment, secrets, or production control.
Secure the path from source change to production. Practice CI/CD threat modeling, least-privilege workload identity, safe handling of untrusted contributions, dependency controls, provenance verification, runner isolation, governed gates, and release evidence.
Run an application-security vulnerability program from discovery through verified closure. Use a realistic Harborline service inventory to practice asset ownership, SBOM and dependency analysis, KEV, EPSS, CVSS, remediation SLAs, exceptions, and release decisions.
Architect, build, deploy, and operate a secure cloud-native application. Use realistic telemetry, risk, identity, network, data, Kubernetes, serverless, supply-chain, and resilience evidence to make enterprise release decisions.
Learn with AI-guided, language-aware content inside realistic development scenarios—not endless slide decks. Every lesson gives you a pattern you can use in your next pull request.
