Course Description

Red Teaming & Penetration Testing for LLMs is a carefully structured course is designed for security professionals, AI developers, and ethical hackers aiming to secure generative AI applications. From foundational concepts in LLM security to advanced red teaming techniques, this course equips you with both the knowledge and actionable skills to protect LLM systems.

Throughout the course, you'll engage with practical case studies and attack simulations, including demonstrations on prompt injection, sensitive data disclosure, hallucination handling, model denial of service, and insecure plugin behavior. You'll also learn to use tools, processes, and frameworks like MITRE ATT&CK to assess AI application risks in a structured manner.

By the end of this course, you will be able to identify and exploit vulnerabilities in LLMs, and design mitigation and reporting strategies that align with industry standards.

Key Benefits for You:

  • LLM Security Insights:
    Understand the vulnerabilities of generative AI models and learn proactive testing techniques to identify them.

  • Penetration Testing Essentials:
    Master red teaming strategies, the phases of exploitation, and post-exploitation handling tailored for LLM-based applications.

  • Hands-On Demos:
    Gain practical experience through real-world attack simulations, including biased output, overreliance, and information leaks.

  • Framework Mastery:
    Learn to apply MITRE ATT&CK concepts with hands-on exercises that address LLM-specific threats.

  • Secure AI Development:
    Enhance your skills in building resilient generative AI applications by implementing defense mechanisms like secure output handling and plugin protections.

So far, the content is what I would expect as introduction material and level setting on key terms.

By Joseph Wilder on 6/23/2026

A great primer for understanding what penetration testing is in general, with a focus on LLM pentesting.

By Josh Williams on 12/25/2025

It makes me sad that in the previous video your guy had to basically apologize for his accent. You guys have great english that I can understand clearly as a native speaker. Do not apologize for your accents, you are doing a fine job. I am excited to work through your course!

Way too many video, with very poor structure. There is very few videos related to the topic under discussion, but overall a huge disappointment.

By Anjali P on 7/22/2025

good explanation of each module
