8 Best Kali Linux Courses & Certifications in 2026

Last updated: August 2026. Written by Josh Hutcheson, OnlineCourseing editor. See our review methodology.

QUICK VERDICT

Kali Linux is the Debian-based distribution that ships with several hundred security tools preinstalled, maintained by OffSec — the same organisation behind the OSCP certification. It is the default working environment for penetration testers, and searching for “Kali Linux courses” is how most people start.

It is also, quietly, a slightly wrong search. Kali is a toolbox with a package manager. The skill you are buying a course for is penetration testing — reconnaissance, exploitation, privilege escalation, reporting — and Kali is simply the machine you do it from. The best courses reflect that. The worst ones spend three hours on installing VirtualBox.

There is a second problem, and it is the reason this guide is structured the way it is. Kali is a rolling release — tools are added, renamed and dropped continuously. A course recorded in 2019 will show you menus that no longer exist and tools that have since been archived. When we opened every Kali-branded course on the major platforms and checked its last-updated date, the pattern was hard to miss: the Kali-specific catalogue is old. We have said so on each entry below rather than presenting a 2019 recording as a 2026 recommendation.

How we chose these courses

Every course on this page was opened at the provider’s own site in August 2026. We recorded its live rating, review count and last-updated date, and we removed anything that had been withdrawn — four courses that older versions of this guide and several competing lists still recommend now return a dead listing. Where a course is still worth taking but visibly dated, we have kept it and said so, because “last updated 2020” is information you need before you spend an evening on it.

The best Kali Linux courses in 2026, compared

The three worth paying for in 2026

1. Learn Ethical Hacking From Scratch — Udemy (best overall)

Zaid Sabih’s course is the one we recommend to most people asking about Kali, and the reason is boring but decisive: it is actually maintained. At the time of writing it shows 4.6 from 137,367 ratings across 142 lectures, and it was last updated in November 2025 — which, in a catalogue where most Kali courses stopped in 2020, puts it in a category of its own.

It teaches every technique on Kali from the first lecture, moving through network penetration testing, gaining access, post-exploitation and web application testing. The structure is the right one — you install Kali in the first twenty minutes and then spend the rest of the course doing something with it, rather than touring the menus.

Best for: almost everyone starting out, and anyone who wants one course rather than a shelf of them. Watch out for: the breadth is real but the depth on any single topic is introductory — this gets you competent, not certified.

2. IBM Cybersecurity Analyst Professional Certificate — Coursera (best credential)

If the goal is a job rather than a hobby, a Udemy certificate of completion will not carry you and this will get you further. IBM’s Professional Certificate is a 14-course series rated 4.6 from 28,353 reviews with 363,228 learners enrolled, designed around roughly four months at ten hours a week, and it explicitly prepares you for the CompTIA Security+ exam — which is the entry credential that actually appears in job listings.

It is not a Kali course, and we are not pretending otherwise. It is a security-analyst programme that covers the defensive and analytical side alongside the offensive tooling. But the honest answer to “what should I take if I want to work in security” is closer to this than to a three-hour Kali walkthrough, and it is the pick on this page most likely to change your employment prospects.

Best for: career changers who need something on a CV. Watch out for: it is a subscription, so the real cost depends on how fast you move — finish in three months rather than eight and you pay less than half.

3. Kali Linux Revealed (KLR/PEN-103) — OffSec (best free option)

This is the official course, written by the people who build the distribution, and it is the only material on this page guaranteed to describe Kali as it actually ships today. It covers installation, system configuration, package management, networking and Debian fundamentals — the “how the machine works” layer that the video courses skip and that turns out to matter most when something breaks.

In OffSec’s own words, KLR/PEN-103 “is still a free offering for students, or can be enjoyed as part of an OffSec Learn One or Learn Unlimited training subscription,” and passing the exam earns the Kali Linux Certified Professional (KLCP) certification. One practical note: OffSec state that the course “has changed locations”, and the old offsec.com/courses/kali-linux-revealed/ URL now returns a 404. Guides still pointing there are sending you to a dead page — the live home is offsec.com/kali-training.

Best for: everyone, genuinely — it is free, so there is no reason not to work through it alongside a video course. Watch out for: it is a book-and-exercises format rather than video, which suits some people and not others. We have no affiliate relationship with OffSec; this is here purely on merit.

Older Kali courses that are still useful — if you know the date

These four are all live and all decently rated, and every one of them is old. That does not make them worthless — the fundamentals of network scanning and exploitation have not changed — but you will meet interface differences, retired tools and outdated Kali versions. We list them with their real dates rather than quietly presenting them as current, which is the single most common failure in guides like this one.

4. Penetration Testing, Threat Hunting, and Cryptography — Coursera (IBM)

The exception in this section — it is current, not dated. A focused 6-module, roughly 10-hour intermediate course rated 4.6 from 2,543 reviews with 118,124 enrolled. It is one component of the wider IBM programme, so take it standalone if you want the penetration-testing piece without committing to the full 14-course certificate.

Best for: filling a specific gap in a week rather than starting a four-month programme.

5. Penetration Testing with KALI and More: All You Need to Know — Udemy

Rated 4.5 from 998 ratings with 44,721 students across 84 lectures, and the broadest Kali-specific syllabus of the paid courses here. It was last updated in December 2020. That is close to six years on a rolling-release distribution, and it is worth knowing before you start — several tools demonstrated in it have since been renamed or dropped from the default install.

We mention the date explicitly because other Kali course roundups rank this course highly without flagging it at all. The methodology it teaches is sound; the specific commands and screenshots are not current.

6. Practice Your First Penetration Test: Kali & Metasploit Lab — Udemy

Rated 4.3, and the value here is the framing rather than the content volume: it walks you through building a small lab and running an end-to-end test against a deliberately vulnerable target, which is exactly the exercise that turns tool knowledge into understanding. It is dated, and Metasploit’s interface has moved on, but the shape of the exercise still holds.

Best for: your first complete run-through, if you learn better by doing one whole thing than by studying parts.

7. Kali Linux Hacking Lab for Beginners — Udemy

4.4 from 2,281 ratings, 20 lectures, last updated August 2019 — the oldest thing we have kept on this page. It survives the cut only because it is short, cheap and genuinely beginner-pitched, which makes it a reasonable evening’s orientation before you commit to something longer. Treat it as a taster, not a syllabus.

8. Network Penetration Testing Using Python and Kali Linux — Pluralsight

Gus Khawaja’s course, at intermediate level and 1 hour 23 minutes, last updated January 2023. It is narrow by design — scripting your own network testing tools in Python rather than driving prebuilt ones — and that narrowness is genuinely useful once you have the basics, because writing a scanner teaches you what a scanner does.

Best for: people who already pay for Pluralsight. Watch out for: at 83 minutes it is not worth a subscription on its own.

Courses we removed, and why

Four Kali courses that earlier versions of this guide linked — and that still appear on other roundups — have been withdrawn from Udemy. Their URLs do not 404; they quietly redirect to the Udemy homepage, which is why stale lists keep recommending them. If a guide sends you to any of these, it has not been checked in a long time:

• Kali Linux Tutorial for Beginners — withdrawn
• Kali Linux Web App Testing — withdrawn
• Wi-Fi Hacking with Kali — withdrawn
• Digital Forensics with Kali Linux — withdrawn

What about “Learning Kali Linux” on LinkedIn Learning?

Two LinkedIn Learning titles come up constantly in searches around this topic: Learning Kali Linux and Penetration Testing: Advanced Kali Linux. They are real courses and they are reasonable, so here is the honest position: they are perfectly decent introductions, they are included with a LinkedIn Premium subscription, and if you already have Premium through work they cost you nothing extra and are worth an afternoon.

We are not linking them, because we have no affiliate relationship with LinkedIn Learning and would rather say that plainly than route you through something that does not work. If you do not already subscribe, we would not start one for these — the free Kali Linux Revealed material covers the same ground with more authority, and the Udemy pick above goes considerably deeper for the price of a takeaway.

Is there a Kali Linux certification?

Yes. The Kali Linux Certified Professional (KLCP) is the official certification, earned by passing the exam attached to Kali Linux Revealed (KLR/PEN-103). It certifies competence with the distribution itself — configuration, packaging, customisation — rather than penetration-testing skill, which is a distinction worth understanding before you decide whether you want it.

Because OffSec build both Kali and the certification ladder above it, their own course catalogue is the clearest map of where Kali skills lead. Taken from OffSec’s Kali training page directly:

Note the branding change: the credential from PEN-200 is now written OSCP+. Access is sold through OffSec’s Learn subscriptions — Learn Fundamentals at $799/year and Learn One at $2,749/year at the time of writing, with the latter including a free KLCP exam attempt. Prices change; check before you commit.

For employability, OSCP+ is the one that moves salaries, and it is a serious undertaking — a 24-hour practical exam, not a multiple-choice paper. KLCP is a reasonable stepping stone; Security+ via the IBM certificate above is the cheaper first credential for most people.

Free ways to learn Kali Linux

You can get a long way without paying anything, and for the first month or two we would argue you should:

• Kali Linux Revealed — the official book and training, free, with practice exams leading to KLCP.
• The Kali documentation — genuinely good, and the only source guaranteed current. The Kali Training page explains how the book and exams fit together.
• TryHackMe — guided browser-based rooms with a generous free tier; the gentlest on-ramp to hands-on practice.
• Hack The Box — harder, less hand-holding, closer to a real engagement. Move here once TryHackMe stops being difficult.

The practice platforms matter more than the video courses, and it is worth being blunt about why: watching someone else run nmap teaches you almost nothing. These give you targets you are explicitly authorised to attack, which is the only legal way to practise unless you build your own lab.

What you should actually learn first

The most common reason people stall is not the tools — it is the layer underneath. If you cannot read a routing table or explain what a three-way handshake is, nmap‘s output is just noise, and no amount of Kali tutorials will fix that. In rough order: Linux command line and filesystem, then TCP/IP and networking, then web technologies, and only then the tool catalogue.

If that describes a gap for you, start with computer networking courses before any of the picks above. It feels like a detour and it is the fastest route.

Kali Linux vs Parrot OS and the other security distros

Kali is the default answer, and for a beginner it is the right one — the largest community, the most tutorials, and the tightest match to what courses assume. Parrot OS is lighter and includes privacy tooling; BlackArch ships a far larger package set for people who already know what they want. None of this changes what you learn, and switching distros later is trivial. Pick Kali, learn the craft, and revisit the question when you have a reason to. We compare the options in detail in our guide to the best Linux distros for hacking and penetration testing.

Where Kali Linux skills lead

Kali proficiency on its own is not a job title. It shows up as a component of penetration tester, security analyst, red team operator and security consultant roles, usually alongside a credential — Security+ at entry level, OSCP+ for offensive roles specifically. The realistic path for most people is: learn the fundamentals, get comfortable on practice platforms, earn Security+ or the IBM certificate, then decide whether the OSCP+ investment makes sense for the roles you actually want.

Kali Linux courses: frequently asked questions

What is the best Kali Linux course?

Learn Ethical Hacking From Scratch on Udemy, rated 4.6 from 137,367 ratings and last updated November 2025. It teaches penetration testing on Kali from the first lecture and, unlike most Kali-branded courses, it is actively maintained. Pair it with the free official Kali Linux Revealed material.

Is there an official Kali Linux certification?

Yes — the Kali Linux Certified Professional (KLCP), earned by passing the exam attached to Kali Linux Revealed (KLR/PEN-103) from OffSec. The course itself remains free for students. KLCP certifies command of the distribution; OSCP+ from PEN-200 is the credential that carries weight for penetration-testing roles.

Can I learn Kali Linux for free?

Yes, and for the first month or two you probably should. Kali Linux Revealed is free from OffSec, the Kali documentation is thorough and always current, and TryHackMe and Hack The Box both have free tiers with authorised practice targets. Pay for a course when you want structure, not because free material is unavailable.

Is Kali Linux hard to learn?

Kali itself is not hard — it is Debian with a large package set, and installing it takes twenty minutes. What is hard is the underlying knowledge: Linux administration, networking and web technologies. People who struggle with Kali are almost always struggling with those, not with the distribution.

Why are so many Kali Linux courses out of date?

Because Kali is a rolling release and course recording is expensive. Tools are added, renamed and retired continuously, so a course is visibly dated within two or three years unless the instructor re-records. When we date-checked the Kali catalogue in August 2026, most paid Kali-specific courses had not been updated since 2019 or 2020, and four had been withdrawn entirely.

Do I need to install Kali to take these courses?

You will want to, and it should be a virtual machine rather than your main operating system. Most courses walk through the VirtualBox or VMware setup. Alternatively, TryHackMe gives you a Kali machine in the browser with nothing to install, which is a reasonable way to start before committing disk space.

Is it legal to use Kali Linux?

Downloading and running Kali is entirely legal — it is a Linux distribution. Using its tools against systems you do not own or have written permission to test is not, and is prosecuted under the Computer Fraud and Abuse Act in the US and the Computer Misuse Act 1990 in the UK. Practise on your own lab or on platforms that grant explicit permission. We cover this in full in is ethical hacking legal?

Is a Kali Linux course enough to get a job?

No. A course teaches you the tools; employers hire for demonstrated ability plus a recognised credential. The realistic combination is a practical course, sustained practice on TryHackMe or Hack The Box, and either Security+ (via the IBM certificate above) or OSCP+ depending on the role you want.
