In progress

Every Appfend lab runs in an ephemeral environment. Your engineers click once, get a real environment in the browser in seconds, and start working on real stack.

[ Real Environments ]

The exact tools your engineers use every day.

A full VS Code instance for coding labs. Gitea for code-review labs. AWS for cloud security work. Real terminals for infrastructure. Every lab spins up its own container, with no local setup, no shared sandbox, and no proprietary environment that breaks the moment your developer pushes on it.

[ AI Tutor ]

An AI that guides, not solves.

An AI tutor is embedded in every lab. Developers can ask about the vulnerability, the framework, or the lab itself, and get hints that move them forward without giving away the fix. It builds understanding through guided, Socratic questioning.

[ Coverage ]

Coverage that matches how teams actually ship.

Secure coding across the languages and frameworks your team uses: Node.js, Java, Python, Go, .NET, and more. Plus AWS security, DevSecOps, LLM and AI-assisted code security, and security awareness.

[ Custom Labs ]

Bring your stack. Build your own labs.

Your engineers ship code on proprietary frameworks and internal tools. Appfend lets you build custom labs against your actual stack, running in the same browser-based environment, with the same AI tutor and reporting as our pre-built content.

Your own code, frameworks, and scenarios, not a generic example
Same VS Code labs, AI tutor, and reporting as the pre-built content
Build once, train your team for as long as you need

XSS in React form handler Pre-built

SSRF in AWS Lambda Pre-built

Acme Auth API: bypass scenario Custom

Spring Boot: IDOR in admin controller Pre-built

Billing service: privilege escalation Custom

Workflow engine: template injection Custom

Engagement that lasts beyond the first lab.

Per-stack forums where your team asks questions between labs. XP, badges, and leaderboards for the people who care about them. Certifications for the ones who don't.

Compliance mapping

Every lab maps to the frameworks your auditors care about. Training evidence flows into your compliance reporting automatically, instead of being a separate exercise.

Frameworks covered

PCI-DSS HIPAA NIS2 DORA

LMS integration

SCORM, xAPI, and LTI supported. With LTI, your developers launch live labs directly from your existing LMS, which SCORM can't do for server-based environments.

Standards supported
