Now forging · AI red-teaming

Prove you can break an AI. Earn the mark that proves it.

Guild Cyber turns hands-on offensive AI security into proof of skill you can share and verify, not another certificate to collect. Break a live model in your browser, earn a Guild Mark, and climb a public leaderboard that hiring managers can actually check.

Free to start. Early members keep founding-cohort standing on the leaderboard.

Why we built it this way

In AI security, a stack of certs is a red flag. Proof is the green one.

Hiring managers in this field are skeptical of certificate mills. What they trust is demonstrated work: capture-the-flag wins, public leaderboards, and results they can verify for themselves. Guild Cyber is built to produce exactly that.

The old way: collect certificates

  • A multiple-choice exam you can cram for and forget.
  • A line on a CV that says nothing about what you can actually do.
  • No way for an employer to check the work behind it.

The Guild way: show the work

  • You break a real model, so the skill is the exam.
  • Every Guild Mark links to a public, verifiable record of the solve.
  • Your leaderboard rank is a portfolio a hiring manager can read in seconds.
The loop

Four steps from curious to credentialed

The same loop runs whether you are a first-year student or a red-team lead. Start easy, prove it, share it, climb.

1

Take on a challenge

Pick a prompt-injection puzzle and go up against a simulated AI system in your browser. No setup, no install.

2

Break the model

Get it to do the thing it was told never to do. Leak the secret, jailbreak the guardrail, hijack the agent.

3

Earn a Guild Mark

Your solve is logged as a verifiable micro-credential and added to your public record on the spot.

4

Climb and share

Rise up the leaderboard and post the mark straight to LinkedIn, where anyone can check it.

The two-layer model

An open door, and a summit worth climbing

Guild Cyber runs on two credentials that are built to be different on purpose. One gets the world in the door. The other is the thing you spend years earning.

Layer 1 · On-ramp

Guild Marks

Free, fast, hands-on micro-credentials. Beginner-friendly, and built to be posted the minute you earn one. This is how most people will first meet the brand.

  • Earned in a single sitting, in the browser
  • Shareable to LinkedIn with a public verify link
  • Stack them to climb the Apprentice to Master ranks
Layer 2 · Flagship
By mastery only

The Guild Seal

A hard, proctored, practical credential with a deliberately low pass rate. Its name, its difficulty, and the way you earn it are all separate from the everyday marks. This is the one built to carry real weight over time.

  • Proctored, practical exam, not multiple choice
  • Earned only after mastery across a full track
  • Unlocks Guildmaster rank and standing
We keep the two apart on purpose. The on-ramp is free and easy to share. The Seal is scarce and has to be earned. The prestige only builds if the two never blur together.
Who it is for

One guild, from first-years to flag officers

The apprentice-to-master path reads the same whether you are starting out, competing for the top of a leaderboard, or standing up a national capability. Everyone belongs to the same guild.

Students getting started

Nervous first-years who want a way in that is friendly, hands-on, and gives them something real to show. No experience required, just curiosity and a browser.

Cyber competitors

The capture-the-flag crowd who care about the leaderboard as much as the learning. Rankings here matter more than years on a resume, which is exactly how this field hires.

Government and defense

Commanders and procurement teams who need a capability they can trust and language that maps to the frameworks they already answer to. The guild reads as well in a briefing as it does on Discord.

The curriculum

Three tracks, each mapped to a hiring function

Content is not the moat, since everyone teaches the same frameworks. What sets us apart is rigor, reputation, and results you can prove. We lead with Offense because it is the newest role, the lowest barrier to entry, and the easiest to show off.

Offense Live

Red Team · Adversarial Simulation

Jailbreaks, prompt injection, data extraction, agent misuse. The part people can watch and share. Break an LLM in your browser and post the proof.

Defense Soon

LLM Security Engineering

Building the defenses: securing RAG pipelines, preventing data leakage, and hardening tool and agent access. The blue-team counterpart to every offense skill.

Built to speak to commanders, not just coders

The incumbents were built for engineers. Guild Cyber is built to also be read by the people who write the requirements and sign the contracts. That is the niche we intend to own.

Aligned to NIST AI RMF and the EU AI Act, so results map to the frameworks buyers already answer to.

Questions

Good to know

Do I need experience to start?
No. The first challenge is built for someone who has never done this before. You work in your browser, there is nothing to install, and the early puzzles walk you through the ideas as you go.
Is a Guild Mark the same as the Guild Seal?
No, and that is on purpose. Guild Marks are the free, shareable micro-credentials you earn as you learn. The Guild Seal is a separate, much harder, proctored credential earned only after mastery. Different name, different difficulty, different way of earning it.
Why lead with offense and AI red-teaming?
It is the newest role in the field, so rankings matter more than years of experience, and it is the most fun to watch. Breaking a model in a browser and sharing the result is the most natural on-ramp we could build.
Will employers actually trust this?
That is the whole design. Instead of a certificate they cannot verify, an employer gets a public record of the exact challenges you solved and where you rank against everyone else. Provable work is what this field hires on.
What does it cost?
The on-ramp is free to start. Founding members who join early earn the first marks and keep their leaderboard standing as the guild grows.
