Professional Junior Pentesting Course
Learn professional pentesting by hacking a real corporate network: 7 Windows and Linux servers spread across two subnets you must compromise and pivot through. It closes with a hands-on 24-hour exam against a network you've never seen.

What you'll be able to do
Not "you'll learn about" — when you finish, you execute. Every outcome is a real technique you can demonstrate.
Compromise an Active Directory
From zero access to Domain Admin on the Windows perimeter Domain Controller.
Pivot into an internal network
Turn a compromised host into a springboard, set up tunnels and reach a subnet that was unreachable.
Land RCE on real apps
Remote code execution on Java web apps, CMS platforms and enterprise services.
Escalate privileges
Root/SYSTEM on Linux and Windows by abusing sudo, SUID, services and dangerous configs.
Escape containers
Break out of misconfigured Docker containers and jump from the container to the real host.
Report like a professional
Document an end-to-end intrusion and rate the criticality of every finding.
A corporate network across two subnets
The lab simulates a real company: two segmented subnets with Windows and Linux servers. There's no shortcut into the internal network — you have to pivot.
The perimeter
The network's exposed services: Active Directory, web apps, CMS and file services. The way in — and any of its 4 hosts becomes your springboard into the internal network.
The internal network
The deep services only visible from the inside: enterprise apps, containers and internal services. The protected segment.
The lab is a one-way cascade enforced by network rules: your SpartanOps only reaches Subnet 1; Subnet 2 is closed. The only way to touch Angel, Lava and Fantasma is to pivot — you compromise any of the four perimeter hosts, turn it into a springboard, set up a tunnel, and only then does the internal network 'appear'. This is exactly what happens in a real internal pentest.
The 7 servers you'll hack
These aren't toy labs: it's a full corporate network. 7 Windows and Linux servers across two subnets. You breach the perimeter, pivot inward and keep hacking all the way to the last host.
Your first breach on the Windows perimeter: get in through a misconfigured service and become local admin. Entry point and springboard into the internal network.
A service with anonymous access leaks the keys to the kingdom: from a forgotten credential to root, and your first bridge into the protected subnet.
Compromise the Domain Controller: from zero access to Domain Admin, then use the owned DC as your pivot into the second subnet.
Chain a series of web flaws all the way to RCE and escalate through a dangerous sudo config. The final perimeter challenge before you cross subnets.
Now inside the internal network: exploit a shared network resource, abuse a misconfigured container and crack the host hash offline to take your first target after the pivot.
RCE on a Java web app, PATH-hijacking privesc and a Docker container escape: three jumps to root on the real host.
Authentication bypass, discovery of hidden internal services and insecure deserialization in an enterprise app. The final challenge of the internal network.
The environment is already set up
Your attack machine and your target network, provisioned and ready. Zero setup: open your browser and start hacking.
SpartanOps: your attack machine
SpartanOps is your attack machine, your base of operations. A professional cloud operator station, provisioned just for you, with the full pentesting arsenal already installed and tuned. Launch it from your browser —nothing to install, no VPN, no Kali to set up— and you're already attacking. We build the environment; you focus on breaking into the servers.
A real training ground
A Training Zone is a full simulation of a corporate network: Windows and Linux servers across segmented subnets, with the same structure you would face in a real internal pentest. A controlled lab environment —built and managed by us— where you practice the end-to-end intrusion, from the perimeter to the internal network, with nothing to set up or maintain.
What's included
Everything you need to go from zero to operational.
+15 hours of pre-recorded content
Video lessons at your own pace, to watch and replay as many times as you need.
+140 pages of theory PDF
The written theory behind every module, to study and look up without the video.
7-server Training Zone
A Windows and Linux corporate network across two segmented subnets.
SpartanOps attack machine
A dedicated cloud operator station, ready from your browser.
24h exam + Diploma
A hands-on exam against a fresh network and a verifiable diploma (Certifier).
Discord community
Exclusive group with students and the instructor.
90 days to activate your lab
Activate whenever you want within those 90 days; from then on you get 30 days of lab. The exam can be taken from the day of purchase.
A complete attack campaign
The curriculum follows a real attack chain: from reconnaissance to full domain compromise.
The exam: 24 hours, 2 servers, a network you've never seen
The course closes with a hands-on 24-hour exam, separate from the lab's 7 servers, against a corporate network you've never seen. Two hard servers across two different subnets that force you to pivot: you compromise the first, turn it into your springboard and jump into the second subnet to take the second. You exfiltrate 4 flags (initial access and full control on each server) and, on passing, earn your CPPJ certification. It's not a certificate of attendance: it's proof you can do the job.
4 flags · initial access and full control on each server
