10 Best Cyber Security Courses Online in 2026 (Ranked & Reviewed)

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

QUICK VERDICT

Cyber security remains one of the few technical fields with more open roles than qualified people, and you do not need a degree to enter it. What you need is a structured course that builds current, practical skills and — for most employers — a credential their applicant tracking system recognises.

The difficulty is that “best cyber security course” lists rot quickly, and several of the pages competing for this term are visibly dated — two currently on the first page still carry 2025 in their titles. Every course below was opened at the provider in August 2026 and checked for liveness, rating and last-updated date. Where something is well-rated but ageing, we say so on the entry rather than quietly presenting it as current.

We also rank on merit rather than commission. Two of the strongest recommendations here — the ISC2 free certification and the practice platforms — earn us nothing at all, and we have said so where that is the case.

The best cyber security courses in 2026, compared

1. Google Cybersecurity Professional Certificate — Coursera (best overall)

If you are starting from zero, start here. The numbers are unusual even by Coursera standards: 4.8 from 68,956 reviews with 1,597,984 learners enrolled, across a 9-course series structured around roughly six months at seven hours a week. It assumes no prior experience and no degree.

What makes it the default recommendation is the balance. It covers the security fundamentals — risk, network security, Linux and SQL, incident detection and response, and an introduction to Python for automation — without either drowning beginners in theory or reducing everything to tool tutorials. Google’s name on the certificate does real work with recruiters who do not know the certification landscape.

Best for: career changers and complete beginners who want one structured path rather than a shelf of courses. Watch out for: it is a subscription, so your real cost depends on pace — finish in three months and you pay half what a six-month run costs. And a certificate is not a certification: pair it with Security+ if you want the credential employers screen for.

2. IBM Cybersecurity Analyst Professional Certificate — Coursera

The closest direct alternative to Google’s, and the better pick if your goal is specifically the analyst role. It is a 14-course series rated 4.6 from 28,353 reviews with 363,228 learners enrolled, built around about four months at ten hours a week — and IBM state explicitly that it prepares you for the CompTIA Security+ exam, which is the single most useful thing any beginner certificate can do.

It leans further toward defensive operations than Google’s — threat intelligence, incident response, forensics — and includes more hands-on tooling. The trade-off is a steeper start; it is less gentle with true beginners.

Best for: people targeting a SOC or security-analyst role, and anyone who wants their coursework to double as Security+ preparation. Watch out for: 14 courses is a genuine commitment — the completion rate on long series is not kind.

3. ISC2 Certified in Cybersecurity (CC) — the best free credential

This is the recommendation most lists bury, and it is arguably the highest value-per-pound option on the page. Certified in Cybersecurity is a genuine entry-level certification from ISC2 — the body behind CISSP — aimed at people with no experience, covering security principles, business continuity, access control, network security and security operations.

Unlike a course completion certificate, CC is an actual certification with an exam behind it, which means it carries weight a Udemy badge does not. ISC2 has run a long-standing initiative offering free self-paced training and a free exam attempt to newcomers; availability and terms change, so check the current offer on their site before assuming a price.

We earn nothing from this recommendation — there is no affiliate programme and we are not linking it for revenue. It is here because for someone with no budget and no experience, a real certification at little or no cost is a better first move than any paid course on this list.

Best for: absolute beginners who want a credential before spending money. Watch out for: it is entry-level and recruiters know it — it opens a first conversation, it does not substitute for Security+.

4. Complete Cybersecurity Bootcamp — Zero To Mastery

A structured bootcamp aimed squarely at becoming employable as a cybersecurity engineer rather than at passing a specific exam. It runs from fundamentals through networking, systems security, offensive techniques and defensive operations, and it sits inside ZTM’s subscription alongside their Security+ and networking material.

The differentiator over a video library is the surrounding structure: a defined path, project work, and an active Discord where people are working through the same material at the same time. For learners who start courses and abandon them, that is worth more than another hundred hours of video.

Best for: people who need accountability and a defined route, and who will use more than one course from the subscription. Watch out for: a subscription only makes sense if you finish — if you are fast and self-directed, one-off purchases are cheaper.

5. CompTIA Security+ (SY0-701) Complete Course & Practice Exam — Udemy (best exam prep)

If you have decided Security+ is the goal — and for most people entering the field it should be — Jason Dion’s course is the most efficient route to a pass. 4.7 from 122,465 ratings across 265 lectures, and last updated August 2026, which on a certification course matters more than almost anything else.

One timing note worth knowing before you buy: CompTIA publish that SY0-701 launched in November 2023 and that their exams usually retire about three years after launch, with retirement estimated for 2026. That does not devalue the certification — it is valid three years from the day you pass — but if you are more than six months from sitting it, check the exam calendar first. We cover the detail in our guide to Security+ courses.

Best for: anyone whose next concrete step is passing Security+. Watch out for: it teaches to an exam, by design — pair it with hands-on practice or you will pass with shallow skills.

6. The Complete Cyber Security Course: Hackers Exposed! — Udemy

Nathan House’s first volume is a long-standing favourite for security and privacy fundamentals — 4.4 from 58,603 ratings across 124 lectures. It is genuinely good on threat modelling, operating-system hardening, encryption and the mechanics of how attacks actually work, and it explains the why better than most beginner material.

One caveat we will state plainly: it was last updated in March 2024. The conceptual material has aged fine — encryption and threat modelling do not turn over quickly — but specific tools, interfaces and product recommendations in it are two and a half years old. Take it for the fundamentals, not for current tooling. Several lists still present this course as though it were freshly maintained; it is not.

Best for: understanding security concepts deeply rather than preparing for an exam. Watch out for: the age, and the fact that it is volume one of four — the full series is a substantial commitment.

7. Cybersecurity for Beginners — Zero To Mastery

A deliberately gentle entry point covering the common attacks people actually encounter and how to defend against them, with no prior knowledge assumed. It is shorter and lighter than the full bootcamp, which is exactly the point — it answers “is this field for me?” before you commit six months.

Best for: testing your interest cheaply, or non-technical staff who need practical security awareness rather than a career. Watch out for: it is foundational by design — nobody is getting hired on this alone, and it is a step toward the bootcamp rather than an alternative to it.

8. Introduction to Cybersecurity Nanodegree — Udacity

Udacity’s model is different from everything else here: project-based work with human review. You build and submit projects, and a reviewer sends them back with feedback until they meet the standard. For people who learn by doing and stall on passive video, that feedback loop is the whole value proposition.

The programme covers security fundamentals, defending and securing systems, threat assessment and governance. It is the most expensive route on this page by a wide margin, and whether that is justified depends entirely on how much you value reviewed project work over self-assessment.

Best for: learners who need external accountability and want portfolio pieces someone has critiqued. Watch out for: the price, and Udacity’s habit of restructuring its catalogue — confirm the programme is still enrolling before you plan around it.

9. IBM Cybersecurity Fundamentals Professional Certificate — edX

The same IBM curriculum family delivered through edX rather than Coursera, in a more academic, module-and-deadline format. Which platform suits you is largely a question of temperament: Coursera’s pacing is looser and more self-directed, edX runs closer to a university course.

It is worth checking both before you commit, because pricing models differ and the same material is sometimes cheaper on one than the other depending on current promotions.

Best for: people who prefer structured deadlines and a university-style rhythm. Watch out for: considerable overlap with the Coursera IBM certificate — pick one, not both.

10. Fundamentals of Cybersecurity — Codecademy

Codecademy’s strength is that you type things. The path runs in the browser with interactive exercises rather than video, which suits people who find watching someone else work unbearable and who retain more by doing.

It is narrower than the professional certificates and it does not lead to a recognised credential, so treat it as a skills-building supplement rather than the spine of your plan.

Best for: hands-on learners who bounce off video courses. Watch out for: no certification at the end, and less depth than the certificate programmes above.

Cyber security certifications: what employers actually want

This is where most people waste money, so it is worth being blunt. A course certificate proves you watched something. A certification is an exam administered by an independent body, and it is what applicant tracking systems are configured to look for. They are not interchangeable, and the marketing on both deliberately blurs the line.

The single most common mistake is chasing CISSP too early. It enforces five years of verified experience, and pursuing it before you have that is a long detour. For almost everyone reading this, the correct sequence is: a foundational course, then Security+, then specialise. Our guide to cybersecurity certifications by career stage maps the full ladder, and the SecurityX guide covers where the CompTIA track ends.

The skills these courses are actually teaching you

Course marketing tends to list technologies rather than capabilities, which makes comparison harder than it needs to be. Underneath the branding, every credible beginner programme is building the same six competencies. Knowing them lets you spot what a syllabus is missing:

• Networking. TCP/IP, DNS, routing, firewalls, and what normal traffic looks like so you can recognise abnormal traffic. This is the foundation, and weakness here is the most common reason people stall.
• Operating systems. Comfortable navigation and administration in both Linux and Windows — permissions, processes, logs, services. Most attacks and most detections happen at this layer.
• Threats and attack techniques. How phishing, malware, privilege escalation and lateral movement actually work. You cannot defend a system against a mechanism you cannot describe.
• Detection and response tooling. Reading logs, working with a SIEM, triaging an alert, and following an incident-response process. This is the day job in most entry-level roles.
• Scripting and automation. Usually Python, sometimes PowerShell or Bash. You do not need to be a software engineer, but repetitive work gets automated and the people who can automate it advance faster.
• Governance, risk and compliance. Frameworks, controls, risk assessment and the regulatory context. Consistently the least glamorous and most under-taught area — and the one that carries real weight in interviews, because it is what connects security work to why the business funds it.

Run any course description against that list. Beginner courses that cover only threats and tooling leave you with the most visible third of the job and none of the foundation, which is exactly the gap that shows up in a technical interview.

How the platforms differ — and what you are really paying for

The five platforms on this page use genuinely different commercial models, and the sticker price tells you very little about what you will actually spend:

The practical consequence: on any subscription platform, your pace is your price. A six-month certificate finished in three months costs half as much, and the single biggest saving available to you is simply blocking out consistent hours rather than drifting. Work out the total before you start, not after.

Cyber security career paths and roles

“Cyber security” is not one job, and choosing a course without a rough destination in mind is how people end up with three certificates and no direction. The main entry routes:

• Security analyst / SOC analyst. The most common entry point. You monitor alerts, triage incidents and escalate. The Google or IBM certificate plus Security+ is the standard preparation.
• Penetration tester. Offensive, and harder to enter directly — most people arrive from an analyst or sysadmin role. It rewards demonstrable hands-on skill more than any other path. See our penetration testing courses and ethical hacking courses guides.
• Security engineer. You build and harden rather than monitor. Strong systems and networking foundations matter more here than any certificate.
• GRC — governance, risk and compliance. Consistently the most overlooked route and often the easiest entry for career changers from audit, law or project management, because the transferable skills are real.
• Digital forensics and incident response. Investigative work after the fact. Specialist and rewarding — see digital forensics courses.

If you do not yet know which appeals, that is an argument for a broad beginner certificate rather than a specialist course — the Google certificate touches enough of each to let you find out.

Starting cyber security with no experience

The honest version, in order:

• Fix the foundations first. Networking and operating systems underpin everything. If you cannot explain what a subnet is or navigate a Linux filesystem, security material will not stick. Networking courses are the usual gap.
• Take one broad course and finish it. One completed certificate beats four abandoned ones. Google or IBM.
• Get hands-on early and continuously. Employers ask what you have done, not what you have watched. TryHackMe and Hack The Box exist for exactly this and both have free tiers.
• Earn Security+. This is the step that changes how many replies you get.
• Accept an adjacent first role if offered. Helpdesk, IT support and sysadmin roles are the most common real-world routes into security, and internal moves are far easier than external ones.

The field genuinely does have more openings than qualified candidates, but “qualified” is doing a lot of work in that sentence — the shortage is of people with demonstrable skill, not of people with certificates.

Free ways to learn cyber security

You can get a long way without paying, and for the first couple of months you probably should. None of these earn us anything:

• TryHackMe — guided, browser-based rooms with a generous free tier. The gentlest on-ramp to hands-on work, and the one we would start with.
• Hack The Box — harder, less guidance, closer to real engagements. Move here once TryHackMe stops feeling difficult.
• ISC2 Certified in Cybersecurity — as above, a real certification with free training and exam availability that has run for some time. Check current terms.
• Professor Messer — the full Security+ video course, free, and the community’s standard free answer for exam prep.
• Vendor documentation and audit — unglamorous and genuinely effective. Reading how a system is meant to be secured teaches more than most beginner courses.

Pay when you want structure, accountability or a credential — not because the free material is inadequate. It is not.

How to choose a cyber security course

• Check the last-updated date before anything else. Security content dates faster than almost any subject. On this page, the newest pick was updated this month and the oldest in March 2024 — and we have said which is which.
• Match the format to how you actually learn, not to how you wish you learned. If you have abandoned video courses before, buy structure or interactivity instead.
• Prefer courses with hands-on labs. Watching a SIEM being used teaches very little.
• Know whether you are buying a certificate or a certification, and price it accordingly.
• Work out the real subscription cost. A “$49/month” certificate costs $147 or $392 depending entirely on your pace.

What we left out, and why

Three categories dominate the advertising around this search term and none of them made the list. That is a judgement, so here is the reasoning:

• Five-figure bootcamps and degree programmes. Every paid advertisement on this search results page is a university or bootcamp. They are not scams and some are genuinely good, but for a career changer testing the water, spending £10,000–£20,000 before you know whether you enjoy the work is the wrong sequence. Do a $50 certificate first. If you still want the field after six months, the expensive options will still be there — and you will choose one far better informed.
• CEH (Certified Ethical Hacker). Widely advertised, and it does appear in some job listings and DoD-adjacent requirements, which is a real point in its favour. But it is expensive relative to what it demonstrates, and among practitioners it carries noticeably less respect than OSCP for offensive work or Security+ for general roles. If a specific employer requires it, get it. Otherwise your money goes further elsewhere.
• Unmaintained “complete masterclass” courses. There is a large tail of highly-rated cyber security courses on the major platforms whose ratings were earned years ago and whose content has not been touched since. A high rating on a 2019 course is a historical artefact, not a current recommendation — which is why we list a last-updated date on every pick here and flagged the one entry on this page that is two years old.

Is learning cyber security worth it in 2026?

Yes — with one honest caveat. Demand is real and durable: organisations keep getting attacked, regulation keeps tightening, and defensive work does not automate away easily. It is also one of the last well-paid technical fields with a genuine non-degree entry route.

The caveat is that the entry level is more competitive than the headline shortage statistics imply. Those numbers count unfilled experienced roles; junior positions attract very large applicant pools, many holding the same certificate. What separates candidates is demonstrable hands-on work — a practice-platform profile, a home lab, a writeup of something you actually did.

So: worth it, provided you treat the course as the beginning rather than the qualification. The people who struggle are almost always the ones who finished a certificate and stopped.

Frequently asked questions

What is the best cyber security course for beginners?

The Google Cybersecurity Professional Certificate on Coursera — 4.8 from 68,956 reviews with nearly 1.6 million enrolled, across 9 courses over about six months at seven hours a week. It assumes no prior experience or degree. Pair it with CompTIA Security+ if you want a credential employers screen for.

Can I get a cyber security job with just a course?

Rarely on its own. A course plus a recognised certification plus demonstrable hands-on work is the combination that gets interviews. Junior applicant pools are large and many candidates hold the same certificate, so the differentiator is evidence you have actually done something — a practice-platform profile, a home lab, or an adjacent IT role.

Is there a genuinely free cyber security certification?

Yes. ISC2’s Certified in Cybersecurity (CC) is a real entry-level certification from the body behind CISSP, and ISC2 has run a long-standing initiative offering free training and a free exam attempt to newcomers. Terms change, so check current availability on their site. It is entry-level, but it is a certification rather than a completion certificate.

Do I need a degree for cyber security?

No. It is one of the few well-paid technical fields with a genuine non-degree route, and certifications plus demonstrable skill are widely accepted. Some government and defence roles do impose degree or clearance requirements, so check the specific sector you are targeting.

How long does it take to learn cyber security?

To reach entry-level employability, roughly six to twelve months of consistent study for someone starting without an IT background — a broad certificate takes about six months at seven to ten hours a week, and Security+ adds another six to ten weeks. Coming from an IT role, considerably less.

Google or IBM certificate — which is better?

Google’s is gentler and broader, and the better default for a true beginner. IBM’s is more defensive-operations focused, more hands-on, and explicitly prepares you for Security+ — the better choice if you already know you want the analyst path. Do one, not both; the overlap is substantial.

Which certification should I get first?

CompTIA Security+ for almost everyone — it is vendor-neutral, has no enforced prerequisite, maps to US federal work roles, and is the credential most commonly filtered on. ISC2’s free CC is a reasonable stepping stone before it if budget is the constraint. Avoid CISSP early: it enforces five years of verified experience.

Are cyber security courses on Udemy any good?

The best ones are excellent value, but quality varies enormously and stale courses are common. Check the last-updated date and the rating count, not just the rating — a 4.7 from 300 ratings on a 2019 course tells you far less than a 4.7 from 120,000 on one updated this year. Both Udemy picks on this page are dated in their entries for exactly that reason.
