About · CybeDefend

Built by experts.
One conviction.

Every team shipping with AI agents deserves security that works where the agent works.

So far

Three engineers start CybeDefend in Lille.

After trying every tool on the market inside large companies, they saw that AppSec needed a new kind of product.

Values

Four values.
Zero compromises.

Innovation

Leveraging AI and agent-loop architecture, we stay ahead of the curve, continuously rewriting what security means for AI agents.

Accessibility

Advanced security should be available to every builder, regardless of company size or budget. Free tier, transparent pricing, no enterprise-only gates.

Transparency

Clear pricing. Open documentation. Honest verdicts. We refuse to add to the alert pile, if we can't verify, we don't page.

Collaboration

Built for teams. Bridging developers and security engineers with one source of truth that lives where the code is written.
