Hands-on IT labs in the browser
Every lab is a job task in the tool that job uses: a Linux prompt, a Cisco-style console, a Windows desktop, a cloud panel, a firewall table or a risk register. Nothing to install, and the grader reads the end state you leave behind, not the route you took.

What the catalogue holds
160 hours of lab time| Tier | Labs | How much help you get |
|---|---|---|
| Guided | 287 | Instructions in order, one step at a time, verified as you go. |
| Assisted | 334 | Short prompts and hints; you choose more of the steps yourself. |
| Challenge | 103 | The goal only. You plan the steps and find out at the end, like the job. |
| Capstone | 20 | One incident or project across several tools, closing a module. |
Size is separate from tier: 555 quick labs are one job, 189 in-depth labs string several jobs together. Minutes are the authored estimate shown in the app, not a deadline.
What a lab looks like
- A ticket, not a quiz. Each lab opens with a work request: who asked, what they need, and by when. The people are invented; the job is the one the exam tests.
- The tool a professional would open. A Windows desktop, a Linux bash prompt, a Cisco-style console, a cloud panel, a firewall rule table or a risk register. Nothing to install and no remote machine.
- Goals, never answers. The steps panel says what to achieve and where. Hints climb from a nudge to a near-answer; the exact commands stay out of the panel.
- Prove it in the tool. You finish the way the job finishes: ping and show output, ls -l, a packet test, a policy simulator, a re-run scan. The end state is graded, not the route you took.
- A score report and a debrief. Every goal is marked met or not, with the reason. The debrief links the lab back to the lessons it came from, so a miss becomes a study note.
Desktop or console
Two kinds of workspace, and the badge on each lab says which one you get. Neither is easier: both are graded on the state you leave behind.
Console labs: you type
Linux bash, Cisco-style device consoles and cloud CLIs accept real commands and print realistic output. Modes, abbreviations and error wording behave the way the real tool does, and the state behind the prompt decides whether the step is done.
Desktop and workbench labs: you click
Windows settings, Device Manager, a cloud console panel, a firewall zone table, a risk register, a SIEM queue or a hardware bench. Same grading rule: the end state, not the sequence of clicks.
Some labs do both
Cloud panel labs show the aws or az line a click stands for, and network labs pair the device console with a topology canvas. Type or click, the same state has to end up right.

A lab can use more than one surface, so these rows count labs per surface rather than adding up to the catalogue total.

Free tier, no card. Pro starts with a 7-day trial.
Questions about the labs
No. Every lab is an original job task mapped to the published objectives. The scenario, the ticket text and the data are written for SecLern; nothing is copied from a live exam.
Start with a free taster lab
Open the catalogue, pick a lab marked free, and work the ticket in the real workspace. The lessons it builds on and the rest of the set are in the same place.
Free tier, no card. Pro starts with a 7-day trial; a card is required and you can cancel before day 7.
