### 🎓 Columbia’s $99 AI security course, for $0 — anyone can enroll

 ![Columbia Engineering · AI Cybersecurity & Governance — $99 struck to $0, promo code CYBER26, one code three courses](https://onehack.st/uploads/default/original/3X/8/3/839c71927aeed608153c03848dea4545be266f55.jpeg)

**AI Cybersecurity & Governance** is a real course from **Columbia Engineering** , listed on [Columbia+](https://plus.columbia.edu/) at **$99**. For a limited time [its course page](https://plus.columbia.edu/content/ai-cybersecurity-governance) states it plainly: _“use promo code CYBER26 at checkout to enroll in this course for free.”_

**Anyone can enroll — a personal email is enough.** That is Columbia’s own wording, on [their FAQ page](https://plus.columbia.edu/frequently-asked-questions): _“Anyone is welcome to enroll in Columbia+, including those outside of the Columbia University community.”_ Registering with a UNI is optional.

**Four steps**

1. Make a free [Columbia+ account](https://plus.columbia.edu/user/login) — a personal email address, no UNI.
2. Open [AI Cybersecurity & Governance](https://plus.columbia.edu/content/ai-cybersecurity-governance) and tap **Enroll**.
3. At checkout type **CYBER26** — the **$99** turns into **$0**.
4. Add basic contact details, and the course is yours. Nothing left to pay.

`self-paced · 7 modules · 2 hours a week · no prerequisites`

**What you study:**  **deepfake fraud** , **prompt injection** , **model extraction** , **Shadow AI** , and the governance frameworks behind them — **ISO 42001** , **SAIF** , **AIUC-1**. The breach cases are **Target** , **JPMorgan Chase** and the **OPM**. Lessons come from Columbia faculty and industry practitioners.

**One code, three courses** — Columbia prints **Free with code CYBER26** on two more pages:

1. **[AI Cybersecurity & Governance](https://plus.columbia.edu/content/ai-cybersecurity-governance)** — **7** modules, 2 hours a week.
2. **[Foundations of Blockchain](https://plus.columbia.edu/content/foundations-blockchain)** — **3** modules, 1–2 hours a week.
3. **[Decentralized Finance: Markets, Protocols, and Design](https://plus.columbia.edu/content/decentralized-finance-markets-protocols-and-design)** — trading, lending, stablecoins and governance.

There is **no limit** on how many you take at once, and [the catalogue](https://plus.columbia.edu/course-catalog) lists the rest.

**The fine print, all of it**

- **1-year access** from the day you enroll.
- The certificate is **optional at $20** , after you finish the coursework.
- Self-paced and **not instructor-supported** — no assigned instructor for questions.
- The **$20** certificate is the only money anywhere in this.
