Realistic Cyber Ranges
Build Linux hosts, networks, services, and vulnerabilities around a learning objective. Each range runs in an isolated cloud environment, with access through ArkOne rather than direct exposure to the internet.
AI-Powered Cyber Range Builder
ArkOne
Turn a learning objective into a working Linux cyber range, with instructor and student materials.

What We Do
AI-Powered Environment Design
Describe the exercise in plain English, then refine it through chat or the visual designer. ArkOne checks requests before building and asks you to approve design changes before they apply.
Ready-to-Teach Exercises
Create a range with an Instructor Guide, answer key, and Student Handout. The materials are written for that specific environment, so the lesson matches what students see.
Outthink. Outmaneuver. Outlast.
Master the Strategic Battlefield of Cyberspace
In cyberspace, every move counts, and hesitation can mean compromise. At Black Ark Labs, we equip cyber professionals with the tools and tactical awareness to think several steps ahead. Just like chess, cyber conflict demands foresight, adaptability, and precision. Our platform transforms complex ranges into strategic environments where teams can evaluate options, test operational decisions, and outmaneuver adversarial conditions. Because in this domain, success belongs to those who plan smarter and act faster.
Mission
To accelerate cyber readiness by transforming how complex operational and mission-critical ranges are designed, built, and deployed.
We empower operators, instructors, and defenders with AI-driven tools that generate realistic, scalable, and rapidly configurable range environments, supporting faster preparation, sharper decision-making, and stronger operational performance.
Vision
To redefine cyber environment development through intent-driven automation.
We envision a world where teams can instantly construct accurate, mission-grade range environments, anywhere they operate. Bridging the gap between planning and real-world execution, and elevating operational readiness across government, defense, and enterprise sectors.
Values
We are driven by a commitment to clarity, operational realism, and responsible innovation.
We prioritize precision, adaptability, and security in every capability we deliver, ensuring that our tools create trustworthy environments, enhance readiness, and empower teams to build, operate, and respond with confidence in dynamic conditions.
Take A Quick Tour
From a learning objective to a ready-to-teach exercise
Create the range and the lesson
Tell ArkOne what you want to teach or learn:
I want to learn how to do forward and reverse SSH tunneling.
ArkOne designs the hosts, networks, services, and vulnerabilities for the exercise. Refine the design with the AI assistant and approve changes before they are applied.
The range comes with an Instructor Guide and answer key, plus a Student Handout tailored to the environment students will use. Download the materials as Word or PDF files.
Students practice from a web browser, with a terminal on each host. There is no lab software to install and no VPN or SSH setup required for browser access.
Available Capabilities
Available nowNatural-Language Driven Creation
Start with what you want to teach or learn. ArkOne turns that objective into a structured cyber range with hosts, networks, services, and vulnerabilities.
Available nowDynamic Environment Generation
Create multi-host, multi-network Linux environments for hands-on exercises. Each range runs in its own isolated cloud environment.
Available nowInteractive Visual Designer
Edit, adjust, and fine-tune the range through the visual interface. Use the AI assistant to refine the design by chat, with changes applied only after you approve them.
Available nowAI Assistance
Ask for changes to hosts or services while designing. The assistant also stays available for questions while the range is running.
Available nowPre-Build Checks and Guardrails
ArkOne checks whether a request can be built before starting. Content guardrails keep builds appropriate and give a clear notice if a build is stopped.
Available nowBrowser-Based Host Terminals
Open and maximize a terminal on any host directly from the web page. Use browser access without VPN or SSH setup, or download a VPN configuration for your own tools.
Available nowIsolated Range Access
Ranges are not exposed directly to the internet. ArkOne’s backend connects to the environment, and student access is scoped and expires.
Available nowRange-Specific Teaching Materials
Download an Instructor Guide with an answer key and a Student Handout as Word or PDF. Both are written for the range you built.
AVAILABLE NOW
Range Operations Management: Redefined
Range Management Features
Available nowUnified Range Management
Design, deploy, and access your ranges through ArkOne. See live deployment status and open host terminals from the browser.
Available nowMulti Range Oversight
Work with multiple ranges and see the live status and running rate for each one. Plans include a cap on concurrent ranges.
Available nowCosts Before You Deploy
Review a cost quote before deployment and follow the running rate for each range. Idle ranges can be torn down automatically to avoid forgotten environments.
Available nowDeployment Recovery
Retry a deployment when needed. If failures continue, support receives a ticket pre-filled with the deployment details.
COMMERCIAL PLANS AND ABOVE
Teach with ArkOne
Available nowClasses and Student Access Codes
Turn a range into a class with a chosen number of seats. Export or email one-time access codes; students sign in with a code and do not need an account.
Available nowShared or Individual Ranges
Choose one shared environment or a separate range for each student. Deploy up front or on each student’s first sign-in, with the cost difference shown before you choose.
Available nowA Focused Student Portal
Students see their task, hosts, and terminal. They cannot edit the range, deploy, view billing, or see other students’ work. Access ends when the class does, and an instructor can remove a student at any time.
Available nowTerminal Session Replay
Review how students worked, not only their final result. Recording captures what appeared on screen rather than keystrokes, so passwords entered at hidden prompts are not stored. Recording is off by default, controlled by platform settings, and uses an open format.
Available nowPredictable Question Usage
Daily question limits help keep AI usage and cost predictable. Instructor-controlled student assistance and question review are coming soon.

Plan. Predict. Prevail
The Future Fights in Code. Be Ready.
Build exercises around the skills people need to practice, with the environment and teaching materials prepared together. Instructors can review terminal sessions to understand how a student reached a result. Students work in isolated environments through a browser, while administrators can track usage and avoid paying for idle ranges.
PLANS AND ACCESS
Choose the right fit for your team
ArkOne offers a Free plan and three paid plans: Hobbyist, Commercial, and Gov/Enterprise. Each plan includes a monthly token allotment and a cap on concurrent ranges. Gov/Enterprise is sales-led. Top-up packs add tokens; class add-ons extend student places, seats per class, and simultaneous class ranges.
Sign-in uses Auth0. Payments use Stripe, so ArkOne does not handle card numbers. Terms and privacy consent are recorded, and the legal documents are versioned.
