Why RxCloud

Built for real-world malware analysis

Designed from scratch in Alsace, France, RxCloud CyberLab focuses on accessible Windows, Linux and Kali labs, strong isolation, and practical workflows for cybersecurity researchers.

Free access

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

Instant launch

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

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 Windows and Linux environments, automated capture, Atlas behavior mapping, 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.

21 Live analysis VMs

Distributed Master + Node2 capacity across Windows, Linux and Kali labs.

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.

Environment

Windows, Linux and Kali labs

Windows ReverseLab, Windows PentestLab, Linux ReverseLab, Linux PentestLab and Kali Linux PentestLab environments.

Network

Multi-node isolation with pfSense

Master + Node2 architecture with per-lab VLANs, monitored traffic, and controlled exposure.

Access

Instant HTML5 access

Apache Guacamole brings browser-based RDP / HTML5 access, with PDF/JSON reports and Atlas behavior maps after sessions.

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, multi-node lab capacity, 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

FAQ

Frequently asked questions

Everything you need to know about RxCloud CyberLab before getting started.

What is RxCloud CyberLab?

RxCloud CyberLab is a free, open malware sandbox and cyber analysis arena accessible entirely through your browser. It provides Windows ReverseLab, Windows PentestLab, Linux ReverseLab, Linux PentestLab and Kali Linux PentestLab environments where researchers can study suspicious samples in isolated sessions. Each session captures telemetry automatically and can generate PDF/JSON reports with observed behavior, IoCs and system activity. The platform is built on pfSense network isolation, Apache Guacamole for HTML5 access, Atlas behavior mapping and a custom monitoring stack.

How to use RxCloud CyberLab?

Getting started takes under a minute:

Create an account and verify your email address.
Request a lab slot - choose a Windows, Linux or Kali environment when available.
Wait for your VM to be provisioned.
Join the session directly in your browser via HTML5 RDP.
Upload a sample (.zip) if needed - it appears on the VM desktop in the RxLab Deposit shortcut.
Execute and analyze inside the isolated environment.
End the session when you are done.
Retrieve your reports - PDF and JSON telemetry are generated automatically.

Who is it for?

RxCloud CyberLab is designed for malware researchers, reverse engineers, antivirus testers, pentesters, SOC analysts, cybersecurity students, and curious defenders who need a real, isolated environment to study malware behavior. It is intended for research, education and defensive cybersecurity work only; it is not a VPN, proxy service, hosting platform or environment for real-world offensive activity.
