Run hands-on security training on real machines, in the browser.

Reflare Hydra gives every learner an isolated Linux or Windows environment, at scale, with skills assessment built in.

You bring the curriculum. We run the infrastructure: provisioning, isolation, persistence and scoring, all handled. No installs, no VPNs, no VM farm to babysit.

Reflare builds the platform that hands-on security training runs on. Hydra provisions the environments. Courses and CTF events are simply content that runs on top, whether they're ours or yours.

CEO, Reflare
The platform

One control plane behind every training environment.

Hydra is content-agnostic. The platform provides the machine; your Docker images decide what runs on it.

Any environment you can containerise

Real Linux and Windows, defined by your own images, live in a browser tab in seconds. Forensics, offensive, blue team, Active Directory, CTF.

Isolated for every learner

Each person gets their own container and network. A breach stays inside that one session and reaches nothing else.

Skills assessment, scored by AI

Free-text answers graded across competency domains, with skill-gap analysis and a dashboard for training managers.

Your content, your brand

Run your curriculum white-labelled on your own domain. Hosted by Reflare, in your cloud, or on-premises for data residency.

Compliance programmes

Role-based security training mapped to standards such as PCI-DSS 4.0, so audit evidence comes out of the work itself.
