An instruction hidden in a PDF reaches the agent. A tool-call guardrail stops it before it touches your cloud. This is the kind of attack we teach you to break and fix.

Why AI security, why now

Every company is shipping AI. Few teams know how to secure it. The people who learn this now become the ones who lead it.

Zero to Hero in AI Security

Five stages, each ending with something real you can show. You climb one step at a time, and nothing is used before it’s explained.

  1. Stage 1 M0–M2

    Foundations

    How LLMs work, threat modelling

    You’ll be able to explain how an AI app really works and threat-model it against OWASP and MITRE ATLAS.

    You leave with a threat model of the course’s vulnerable AI app

  2. Stage 2 M3–M6

    Break and fix any AI app

    Prompt injection, data leaks, output handling, RAG

    You’ll be able to run prompt injection and data-leak attacks, then ship fixes and prove them with tests.

    You leave with a break-and-fix write-up with passing tests

  3. Stage 3 M7–M9

    Agents and MCP

    Agent tools, MCP servers, AI supply chain

    You’ll be able to limit what agents and MCP servers can do, and vet models and packages before you use them.

    You leave with a hardened agent and MCP setup with a permissions review

  4. Stage 4 M10–M16

    Secure AI on AWS

    Bedrock, Guardrails, AgentCore, SageMaker AI, detection and response

    You’ll be able to secure an AI workload on AWS end to end and detect attacks against it.

    You leave with hardened Terraform and detection rules for an AWS AI workload

  5. Stage 5 M17–M32

    Prove it and go advanced

    Red teaming, governance, capstone, advanced track

    You’ll be able to red-team an AI app, gate releases on security evals, and map controls to governance frameworks.

    You leave with a red-team report, a graded capstone and a certificate of completion

From zero: no AI or maths background needed. See the full curriculum

The course

AI Security Engineer

Secure what you build with AI — from your laptop to AWS. Defender-first, starts from zero, and built around one deliberately vulnerable AI app you attack and secure from the first module to the capstone.

  1. Part 1 Foundations How LLMs work and how to threat-model them 3 modules
  2. Part 2 Attack and defend any AI app Prompt injection, RAG, agents, MCP, supply chain 7 modules
  3. Part 3 AI security on AWS Bedrock, Guardrails, AgentCore, SageMaker AI, detection 7 modules
  4. Part 4 Prove it Red teaming, evals in CI, governance, capstone 3 modules
  5. Part 5 Advanced track Agent identity, authorization, secure-by-design agents 13 modules
  6. Part 6 Future watch A short “what changed” update every quarter Quarterly

6 parts and 33 modules, from “what is a token” to securing agents on AWS. See every lesson in the curriculum.

What you get

  • Video lessons. Each lesson opens with a real incident, then breaks it and fixes it on screen.
  • PDF slide decks. A downloadable deck for every module.
  • Hands-on labs. A $0 local version and an optional AWS version, each with a walkthrough video and a written guide.
  • Community. Lab help on GitHub Discussions, and a Discord server with student channels (coming soon).
  • Certificate of completion. Earned by passing the graded capstone, with a public verify link.
  • Progress you can see. Badges, ranks and an attack-surface map that lights up as you secure each part.

Who we help

Everyone who works near AI and was never taught to secure it. Start from the job you already do.

It’s OK not to know this yet.

ChatGPT went public in November 2022 and OWASP's first Top 10 for LLM apps followed in 2023. Nobody has ten years of this. The people doing it today came from SOC, cloud, AppSec, development and GRC, the same places you’re coming from.

For teams

Cloud and AI security advisory

For teams putting AI into production on AWS or elsewhere. Every engagement is scoped by email first: tell us what you’re building, which cloud you’re on and your timeline.

Email [email protected]
  • AI app and agent security review

    Your chatbot, RAG app or agent, reviewed end to end: prompts, tools, data paths and permissions, with fixes in priority order.

  • AWS AI platform security

    Amazon Bedrock, Guardrails, Knowledge Bases and AgentCore: identity, network, logging and guardrail configuration checked against your design.

  • Threat modelling

    A working session that maps the trust boundaries of your AI system and ties each threat to OWASP and MITRE ATLAS.

  • AI security readiness

    Where AI is used across your organisation, what it can touch, and a short plan your engineers and auditors can both act on.

Questions

What is The Sec Guy?

An independent cloud and AI security brand. We publish free videos, notes and checklists, run a hands-on course called AI Security Engineer, and advise teams that are shipping AI.

What is free, and what is paid?

Videos, notes, checklists, the daily reels and the free course lessons cost nothing. The full course is a one-time payment. Advisory work for teams is scoped by email.

Do I need an AI, machine-learning or maths background?

No. The course starts at “what is a token”, and every term gets a one-line plain meaning before it’s used. If you can follow a cloud console or a terminal, you can follow this.

Will the labs cost me money?

Every lab runs free on your laptop first. The AWS versions are optional; each prints its estimated cost before it deploys, uses budget alarms, and tears itself down.

How do you keep the content accurate?

Claims link to their primary source, content is independently fact-checked before it’s published, and the course gets a Future watch update every quarter.

Do you track visitors?

No. This site has no analytics and no advertising cookies. The privacy policy lists exactly what is stored, and why.

Can you help my team?

Yes. Email [email protected] with what you’re building, which cloud you’re on and your timeline. Team purchases of the course and invoices in your company’s name are handled the same way.

Are you affiliated with AWS?

No. The Sec Guy is independent and not affiliated with or endorsed by AWS or any other vendor named on this site.
