CybeDefend

Security review is dead. CybeDefend lives inside Claude Code, Cursor, Windsurf and Copilot, and rewrites them safe before they land

[CybeDefend @CybeDefend]

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.

[CybeDefend @CybeDefend]

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

[CybeDefend @CybeDefend]

Most security tools start by scanning. We start by understanding.

We map your whole project into a knowledge graph first: every file, every class, what calls what, and what it is for.

Four thousand nodes on one project. It came out looking like a face.

[CybeDefend @CybeDefend]

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.

#AppSec

[CybeDefend @CybeDefend]

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

[CybeDefend @CybeDefend]

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.

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.

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.

[CybeDefend @CybeDefend]

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.

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.

Writing secure code is easy.*

*only with VibeDefend inside your coding agent, blocking the dangerous stuff before it's written.

No vuln, no bill.

This Friday, CybeDefend is at the Grand Sommet de l'IA in Lille.

2,000+ people, 50+ speakers, under the patronage of President Macron. And Axel takes the stage to pitch what we are building.

A European AI summit in our own city, our team on stage.

[CybeDefend @CybeDefend]

Developers don't write code anymore. Agents do.

Scanning code after it ships is too late. CybeDefend moves security inside the agent, so it scans and fixes before the first line is even done.

Shift-left is dead. We shift to zero.
