We are excited to announce that Securing AI Applications launches on Thursday, April 16th on the TCM Security Academy. The course was created by Andrew Bellini, the instructor behind all of our AI security curriculum, including AI 100: Fundamentals, AI Hacking 101, and the PAPA certification. If you have taken any of those, you already know the quality of instruction to expect here.
Unlike other training that teaches you how to attack AI systems, this course goes deep on how to defend them.
Why We Built This Course
If you have gone through AI Hacking 101, you already know how to think like an attacker targeting AI-powered applications. You have seen how prompt injection works, how retrieval-augmented generation (RAG) pipelines can be abused, and how AI outputs can be manipulated into revealing sensitive information or taking unintended actions.
Securing AI Applications takes the alternate approach. For every offensive technique you learned in AI Hacking 101, you’ll learn the corresponding defensive countermeasure.
Before taking this course, you should take the FREE AI 100: Fundamentals course, which will teach you how AI and LLM models actually work, which is essential for understanding how to exploit and defend them. It’s also recommended you complete AI Hacking 101 before Securing AI Applications.
What You Will Learn
The course is structured around the full lifecycle of securing an AI application, from initial model configuration all the way through to agentic guardrails. Here is a quick breakdown of the curriculum:
- AI Threat Landscape: Understand where AI applications fail in the real world
- Secure Model Configuration: Properly set temperature, token limits, and stop sequences to reduce misuse
- System Prompt Hardening: Write and structure system prompts that are difficult to bypass
- Input Validation: Filter and sanitize user inputs to prevent prompt injection attacks
- Rate Limiting: Protect AI endpoints from abuse and resource exhaustion
- Output Moderation and PII Handling: Ensure AI responses do not leak sensitive or inappropriate content
- Securing RAG: Implement proper access controls around retrieval-augmented generation pipelines
- Agentic Guardrails: Keep AI agents operating within their intended boundaries when they take automated actions
All of this is taught through a custom lab environment featuring a vulnerable chatbot that integrates with a simulated company knowledge base, website, and ticketing system. The labs are hands-on and practical. You are not just reading about defenses; you are implementing them against real attack scenarios.
Who Should Take This Course
This course is designed for three audiences in particular:
Developers building AI-powered applications: If you are shipping products that use LLMs or AI models, you need to understand how those systems can be abused and how to harden them from the start.
AppSec and DevSecOps practitioners: If your job involves reviewing or securing AI-integrated applications, this course gives you a practical, structured framework for doing that work.
Penetration testers who test AI applications: Understanding the defender’s perspective makes you a sharper attacker. Knowing how defenses are built helps you find the gaps that were missed.
The Bigger Picture: TCM’s AI Security Path
This course is the third piece of a cohesive AI security curriculum we have been building. Here is how the pieces fit together:
- AI 100: Fundamentals – Concepts, vocabulary, and how AI systems work
- AI Hacking 101 – Offensive techniques for testing and attacking AI applications
- Securing AI Applications – Defensive implementation and hardening
Ready to Get Started?
Securing AI Applications is available now on the Academy. If you are already a TCM Academy subscriber, it is included in your membership.
AI security is a young and rapidly evolving field. The organizations building AI-powered products often outpace the security practices protecting them. That gap is where skilled defenders matter most, and this course is built to help you close it.
We will see you in the course.
