one command line to secure your coding agent? @cybedefend.
𝚗𝚙𝚡 -𝚢 @𝚌𝚢𝚋𝚎𝚍𝚎𝚏𝚎𝚗𝚍/𝚟𝚒𝚋𝚎𝚍𝚎𝚏𝚎𝚗𝚍 𝚒𝚗𝚜𝚝𝚊𝚕𝚕
one command, and your coding agent writes with your business rules and your security rules in context.
launching today on @producthunt: producthunt.com/products/cyb…
🤝 Paid partnership

this guy literally built a security guard for AI coding agents.
Claude Code writes code.
Cursor writes code.
Codex writes code.
but who’s watching the agent?
VibeDefend sits directly inside the coding workflow and can stop dangerous actions before they happen.
it can enforce your repo rules, scan code as it’s written, protect secrets and flag security issues.
one command to install:
npx -y @cybedefend/vibedefend@latest install
AI agents are moving faster than humans can review.
this is probably a problem we’re going to see a lot more of.

Your AI coding agent can write 500 lines while you read the first 20.
That speed is amazing.
Until it ships something you didn't ask for.
VibeDefend puts security directly inside AI coding agents.
It can enforce your repo rules, scan code as it's written, and block dangerous actions before they happen.
Works with Claude Code, Cursor, Codex, Windsurf & Copilot.
One command:
npx -y @cybedefend/vibedefend\@latest install
If you vibe code, this is worth checking out 👇

We also launched on Product Hunt 😎
DELETE without WHERE. Every engineer's nightmare.
You would hesitate. Your AI agent will not. It runs it at full speed and moves on.
So we gave it the flinch. Watch:
One thing it does, not the whole product.

Day 1/45 | Building & Securing in Public
I’m on a mission to show you what it really takes to build a cybersecurity startup. Over the next few weeks, I’ll be sharing actionable educational content on the cyber risks of AI.
An Amazon coding agent was asked to fix a bug in AWS Cost Explorer. It decided to delete and recreate the prod environment instead. 13 hours down.
Amazon called it user error, not AI. Both true. Agents are probabilistic. Guard the action, not the model.

45 days left. $0 US revenue.
I moved from France to Seattle to sign our first US customer. Documenting every day until it happens
Ask an agent to clean up build files and it runs rm -rf without a second thought. It has no idea which folder holds your users' data.
VibeDefend gives it that idea. Watch:
One capability, not the whole product.

Your AI agent will read your .env. Not because it is malicious. Because it is stuck.
VibeDefend steps in before it touches the raw secret. Watch:
One capability, not the whole product.

#AppSec
Your AI agent wrote a SQL injection. You just have not found it yet.
Nobody reads 5,000 lines a day, so we catch it inside the loop, before it leaves the diff. Watch:
One thing it does, not the whole product.

Our cofounder Julien just landed in Seattle.
His mission: build CybeDefend's first US chapter and land our first American customers. 2 months on the clock.
He's sharing the whole journey, go follow him.

CybeDefend entre dans le Radar 2026 des startups cyber françaises de Wavestone et Bpifrance.
Notre pari depuis le début : la sécurité vit dans l'agent qui code, pas après. Ça commence à compter.
Merci Wavestone et Bpifrance.
#CyberSécurité #AppSec #FrenchTech
The security glow-up is real.
VibeDefend plugs into your coding agent and stops the vulns before they reach your code. Not after. Before.
No vuln, no bill.

Retour sur le Grand Sommet de l'IA à Lille. Axel Paulin a pitché VibeDefend devant 150 personnes, avec Florentin Ledy et Julien Zammit à ses côtés.
Merci à EuraTechnologies et au Campus Cyber pour l'expérience.
#IAAvecNous #FrenchTech #CyberSecurity
Big day for CybeDefend. Axel pitched at Plug and Play while the rest of us followed it live, on edge the whole time.
One on stage, the rest living it from afar. That is what a real team looks like.
It landed, and sparked real interest right after.
#PlugAndPlay #Team
We're heading to Paris. CybeDefend is one of 15 startups selected to pitch at the Assises de la Cybersécurité, in front of the Cercle des Investisseurs. Axel takes the stage for us.
June 17, Paris.
#Assises #CyberSecurity #FrenchTech
Us, watching our coding agents ship clean code on autopilot.
VibeDefend lives inside the agent and kills the vulns before they're written.
No vuln, no bill.
