Battlegrounds™

Always On. Always Ready.

Battlegrounds™ is k>fivefour's browser-based cyber range. Isolated environments, realistic enterprise networks, and scenarios at every tier, available around the clock.

Training That Doesn't Stop After Class

Skills degrade between events and adversary tradecraft keeps evolving. Battlegrounds closes that gap with a live, browser-based range available 24/7, with no special software required. Every user gets an isolated environment built on full Active Directory forests and realistic enterprise infrastructure. Training becomes continuous instead of a one-week event.

Why Battlegrounds

Built Like the Real Thing

Realistic environments, continuous access, and scenarios that scale from your first challenge to the hardest in the library.

Request a Demo

Browser-Based Access

Isolated, per-user environments you reach from any browser, with no special software to install. Train from anywhere, at any hour, without standing up local infrastructure.

Realistic Networks

Full Active Directory forests and realistic enterprise infrastructure, so what you practice on behaves like what you defend or attack in production. Operators can upload their own tools, just like real ops.

Continuous Access

Available 24/7 so training continues long after a course ends. Skills stay sharp between events instead of decaying until the next scheduled exercise.

Team Mode

Multiple users can share an environment for collaborative exercises, mirroring how real teams work a problem together rather than training in isolation.

Tiered Scenarios

A scenario library spanning multiple difficulty tiers, from post-course challenges to the hardest scenarios in the catalog, so there is always a meaningful next rep.

Use Cases

How Teams Use Battlegrounds

One range, several ways to build and sustain readiness.

Request a Demo

Skill Sustainment

Keep Operators Sharp

Give operators continuous reps between courses and exercises so hard-won skills do not decay in the gaps.
Post-Course

Reinforce What You Learned

Extend classroom training with challenges that let students apply new tradecraft immediately, while it is still fresh.
Team Exercises

Train as a Unit

Use team mode to run collaborative exercises where operators work a shared environment together, the way real missions run.
Assessment

Prove Capability

Measure real hands-on performance in realistic environments, not answers on a written test.

Part of the Stack

Battlegrounds and the k>fivefour Ecosystem

Battlegrounds is where operators access training built by the wider k>fivefour platform.

Explore Solutions

Access Point for Training

Battlegrounds is the browser-based front door to k>fivefour ranges and scenarios, whether hosted centrally or deployed on infrastructure at the edge.

Live Adversary Content

Scenarios can be driven by an automated adversary that adapts to defender behavior, giving realistic red-side pressure without staffing a live Red Team for every event.

Self-Service Options

Qualified organizations can build and run their own scenarios through the portal, operating their own persistent training on k>fivefour infrastructure.

FAQs

The questions we hear most about access, environments, and getting started.

Do I need to install anything?

No. Battlegrounds runs in the browser with isolated, per-user environments. You reach it from a standard browser with no special software.

How realistic are the environments?

Environments are built on full Active Directory forests and realistic enterprise infrastructure, not simplified CTF boxes, and operators can bring their own tools.

Is it available all the time?

Yes. Battlegrounds is available around the clock so training continues between courses and scheduled exercises.

Can my team train together?

Team mode lets multiple users share an environment for collaborative exercises, mirroring how real teams operate.

How do we get access?

Request a demo or contact our team, and we will scope access for individuals, teams, or your whole organization.
