Practice, not theory

Security skills you can prove, not just claim.

The industry is not short of people who can explain an attack. It is short of people who can stop one. Employers need practical hands, and this is not a theory shop: every lesson ends on a live range that grades what you built, and every credential is earned by doing the job under pressure.

Foundation is $39 a month until you finish it. Then a cert path: one price, 90 days of live labs, one exam, a signed credential. The first two lessons of Linux 1, with their labs, are free.

Graded by the range

No multiple choice. A lab passes when tests run against the host you built and come back green.

Certifications are practicals

Hours on a live stack under a chaos day or a 48-hour incident, with a human auditing the result.

You leave with something running

Every path ends with a platform, an edge, a pipeline or a detection stack you built, broke and repaired.

What it represents

The whole T: breadth from Foundation, depth in all seven core disciplines. It is the credential of an engineer who can build the platform, defend its edge, run its identity, ship it safely, detect what happens on it, attack it, and write the software that runs on it.

How you earn it

Hold all seven core credentials. It is awarded automatically the day the seventh is issued: no enrolment, no extra exam, no fee.

Questions

What is a T-shaped engineer?

An engineer who knows the whole stack well enough to build and run it (Linux, networks, code, cloud, containers, pipelines, observability, data and security) and one area in depth. T Academy teaches the bar of the T first, in Foundation, then one deep path.

Is this platform engineering training?

Yes. Foundation covers Linux, networking, cloud, containers and Kubernetes, and CI/CD. The Secure Platform Engineering path then goes deep: immutable operating systems and cluster hardening, network policy, service mesh and gateways, storage and databases, streaming, and running the platform as a product.

Are the labs real?

Yes. Every lab is your own isolated Linux host or virtual machine in the browser, not a simulator, and your work is checked against the real state of that system. There are no videos: a short read, then the work.

Do I need experience?

No. Foundation starts from a login prompt and assumes nothing. Each course builds on the one before it, so the order is the plan.

Is everything $39 a month?

No. $39 a month is Foundation only, and it stops the day you finish it. A cert path is a one-time price — the courses, 90 days of on-demand labs and the exam — not a monthly charge.

What exactly is free?

The first two lessons of Linux 1 and their labs, with a free account and no card. Nothing else: every other lesson, course, path and certification is paid.

What happens after the 90-day lab window?

Your courses, notes and write-ups stay for life; the live labs close at day 90. Move on to the next cert when you are ready.

Can I just buy a cert path and start?

No. Every path builds on Foundation, and enrolment opens the day your Certificate of Completion is issued. You cannot pay past it, and that is the point: we want you to succeed on the range, not to buy a seat you cannot use yet.

What is H2-CTSE?

Certified T-Shaped Security Expert — awarded automatically, free, the day you hold all seven core credentials. Signed and self-verifiable like the others.

Why do specialist certs cost more than core?

They are 48-hour practicals on a stack you build during the path, graded by outcome with a human on the other side, and they assume the core.

Teams

Seat pools for the courses, a manager view of who is ready for which certification, and reports you can hand to an auditor. Seats move between people; certifications are bought per person.
