About Us
Cyber Dream
Who We Are
We build things that work, and make sure they stay secure.
Cyber Dream is a French tech company founded by engineers who believe security should never be an afterthought. We combine deep expertise in software engineering and offensive cybersecurity to build reliable, performant digital systems.
Based in Nantes, we work with startups, scale-ups, public organizations, and enterprises across Europe. Our team writes production code daily, runs security audits, builds threat intelligence tooling, and ships open source projects used by the community.
We don't just advise. We build, deploy, and maintain. Every line of code we write is something we would trust with our own infrastructure.
Our Stack
We primarily work with Rust for backend systems, APIs, and performance-critical applications. Its memory safety guarantees, zero-cost abstractions, and fearless concurrency align perfectly with our security-first philosophy.
When the project calls for it, we also work with TypeScript, Python, and Go. Our infrastructure runs on Linux, Docker, and Kubernetes, hosted on European cloud providers.

at the intersection of code & security
We write the systems others trust their business on.
( What We Believe In )
Our core values
Security is Not Optional
Every system we build integrates security from architecture to deployment. We don't bolt it on later. Threat modeling, hardened configs, and secure-by-default patterns are part of our standard workflow.
Clean Code, Real Results
We write code we're proud of. Readable, tested, documented, and built to last. No shortcuts, no spaghetti. If we wouldn't deploy it on our own infra, we won't ship it to yours.
Performance Matters
Rust isn't just a trendy choice for us. We pick it because milliseconds matter, memory safety prevents entire classes of vulnerabilities, and our clients deserve systems that scale without compromise.
Radical Transparency
No black boxes. We share our progress, explain our decisions, and give you full access to the code. You own everything we build for you, always.
Adapt to Your Context
Startup with 3 people or enterprise with 3,000? Public sector or fintech? We adapt our process, our tools, and our communication to fit your team and your constraints.
Open Source First
We actively maintain open source projects and contribute to the security community. We believe sharing knowledge makes everyone safer, and that the best tools are built in the open.
( How We Work )
From first call to production, we handle the full lifecycle.
We're not a body-shopping agency. We take ownership of the projects we work on, from initial scoping through architecture, development, testing, deployment, and ongoing support.
Every engagement starts with a thorough understanding of your technical landscape, business goals, and risk profile. From there, we propose a clear roadmap with milestones, deliverables, and a fixed or time-and-materials pricing model that fits your budget.
-
01
Discovery & Scoping
We analyze your needs, assess risks, and define clear goals with measurable outcomes. No guesswork.
-
02
Architecture & Development
We design robust, scalable systems in Rust (or the right tool for the job) with security and maintainability baked in.
-
03
Testing & Security Review
Every deliverable goes through automated testing, manual code review, and a security hardening phase before shipping.
-
04
Deployment & Support
We deploy to production with monitoring, alerting, and documentation. Post-launch support and iterations are part of our process.
