Why RxCloud

Built for real-world malware analysis

Designed from scratch in Alsace, France, RxCloud CyberLab focuses on accessibility, isolation, and practical workflows for cybersecurity researchers.

Free

Free access

Cutting-edge environments without paywalls, artificial friction, or complex onboarding.

Easy

Instant launch

Open a browser, authenticate, and access your lab through HTML5 RDP with no local setup.

Isolated

Isolated by design

Each environment is segmented behind pfSense with monitored network activity and controlled exposure.

Platform value

A cyberlab that feels like a product, not just a VM pool

The goal is simple: remove friction, preserve safety, and give researchers a polished environment that is actually pleasant to use.

Unlock boundless possibilities

From malware detonation to telemetry review, RxCloud brings together browser access, isolated environments, automated capture, and final reporting into one coherent workflow.

60 min Fair-use sessions

Balanced access that keeps the platform available to everyone.

Auto Telemetry capture

CPU, RAM, network, storage, behavior, and artifacts in one flow.

8 Live analysis VMs

Dedicated PentestLab and ReverseLab pools, ready to launch.

PDF Final report export

Logs, observed behavior, and IoCs summarized at the end of the session.

Services

Plug-and-play labs, monitored and protected by RxCloud

The platform is engineered to provide fast access, strong isolation, and predictable behavior across every session.

Founder

Built by a malware hunter, not a marketing team

Made in France, made in Alsace, and built from scratch with one core idea: give researchers a free, open, isolated cyberlab they can actually use.

RxCloud CyberLab started as a technical challenge and grew into a real platform: browser access, isolated VLANs, monitoring, PDF reports, and a workflow tailored to malware research.

No corporate committee. No investor-driven roadmap. Just a developer focused on building something useful, serious, and accessible.

“I wanted to build the kind of sandbox I would have loved to use myself: open, fast, isolated, and genuinely helpful.” — RoxasDev
