The best Kubernetes security training providers in 2026 are the Linux Foundation and CNCF, for the industry standard CKS and KCSA certifications; ControlPlane, for its four day offensive and defensive Learn By Hacking course; and Practical DevSecOps, for a lab heavy cloud native certification with a six hour practical exam. Below those three sit strong options for CKS exam prep, live attack and defense classes, forensics, runtime detection and free practice clusters.
Kubernetes security training splits into two camps. Defensive courses teach you to harden clusters, write admission policies, lock down RBAC and detect threats at runtime. Offensive courses teach you to escape containers, abuse service accounts and move laterally through a cluster. The strongest teams learn both. If your scope reaches past clusters into the wider cloud account, our list of the top cloud security training providers covers AWS, Azure and GCP, and our guide to cyber ranges and hands-on security training platforms covers ranges for ongoing practice.
We checked every provider’s own site for course content, format and pricing in October 2026.
The Linux Foundation and the Cloud Native Computing Foundation own the two Kubernetes security credentials most employers ask for. The Certified Kubernetes Security Specialist (CKS) is a two hour, online, proctored exam where you solve tasks on live clusters from the command line. Its domains are cluster setup, cluster hardening, system hardening, minimizing microservice vulnerabilities, supply chain security, and monitoring, logging and runtime security. You must hold the CKA first, and the CKS stays valid for two years. As listed on its site in October 2026, the exam costs $445 with one free retake, and the purchase includes two Killer Shell simulator sessions.
For newer staff, the Kubernetes and Cloud Native Security Associate (KCSA) is a 90 minute multiple choice exam listed at $250. Training runs alongside both: LFS260 Kubernetes Security Essentials is a self-paced course of 26 to 30 hours listed at $299, and LFS460 Kubernetes Security Fundamentals is a four day instructor-led class listed at $3,495 that bundles CKS exam registration and simulator access.
Best for: Engineers who need a recognized Kubernetes security certification on their resume.
2. ControlPlane — Three Day Learn By Hacking Course Plus A CTF Day
ControlPlane is a cloud native security consultancy with offices in London, New York, Melbourne and Auckland, and it does threat modelling, penetration testing and supply chain security work for regulated industries. Its flagship class, Advanced Kubernetes Security: Learn By Hacking, was created by Andrew Martin, author of Hacking Kubernetes and a SANS instructor. It runs three days plus a fourth CTF day and covers container exploitation, pipeline and supply chain attacks, image scanning and signing, GitOps with Flux, RBAC, runtime intrusion detection, network policy, service meshes and container isolation, all taught from both the attacker and defender side.
The wider catalog includes a one day Kubernetes and Container Security course, a one day Threat Modelling Kubernetes class, a GRC threat modelling class and the LFS482 SPIFFE and SPIRE zero trust course. Classes mix presentations, demos and instructor-led labs, can be delivered on site or remotely, and ControlPlane can build custom lab environments. Pricing is quote based. The Learn By Hacking class expects working Kubernetes experience, so it suits intermediate and advanced platform teams, pentesters and SOC analysts.
Best for: Platform and security teams that want private, practitioner-led training on attacking and defending real clusters.
Practical DevSecOps runs the Certified Cloud-Native Security Expert (CCNSE), one of the most complete self-paced Kubernetes security programs available. Its ten chapters move from container security and Docker hardening into a full Hacking Kubernetes chapter (dashboard abuse, kube-hunter reconnaissance, kubelet API exploitation, privileged container escapes, malicious Helm charts) and then into defense: RBAC auditing, OPA Gatekeeper and Pod Security Admission, Vault and Sealed Secrets, Istio and Linkerd, CIS benchmarks, gVisor, Falco and audit log threat hunting. The provider says roughly 70% of the course is lab work.
As listed on its site in October 2026, the CCNSE costs $999 (discounted to $849.15 at the time of checking) and includes 60 days of browser-based labs, 40+ guided exercises, a PDF manual and one exam attempt. The exam gives you five real-world challenges in six hours, then 24 hours to submit a report, and the credential does not expire. A separate Certified Container Security Expert (CCSE) focuses on building and analyzing secure container images.
Best for: Practitioners who want a practical Kubernetes security certification that tests both attack and defense.
4. KodeKloud — CKS Course With Browser Labs And Three Mock Exams
KodeKloud, founded in 2019 by Mumshad Mannambeth, is the training platform many engineers use to pass the CKA, CKAD and CKS. Its Certified Kubernetes Security Specialist course is taught by Mannambeth and CTO Vijin Palazhi and follows the CKS domains closely: the Kubernetes attack surface, CIS benchmarks and kube-bench, RBAC and kubelet security, network policies, seccomp and AppArmor, OPA Gatekeeper, gVisor and Kata runtime classes, image security with Trivy and kubesec, and runtime monitoring with Falco and audit logs.
The course has eight modules, about 8.75 hours of video, browser-based labs after each topic and three full mock exams. KodeKloud upgraded the lab environment to Kubernetes 1.32 in 2025. Access comes through a KodeKloud subscription that includes its full library of courses, labs and playgrounds, and some labs can be tried with a free account. It is a lower cost way to build the muscle memory the CKS exam demands.
Best for: Individuals preparing for the CKS exam on a budget.
5. SANS Institute — SEC540 With Nine Container, Supply Chain And Kubernetes Labs
SANS, founded in 1989, now covers Kubernetes inside SEC540: Cloud Native Security and DevSecOps Automation. Containers come up in section two (Dockerfile misconfigurations, Trivy scanning, minimal base images, Conftest policies, SBOMs, Sigstore signing and SLSA provenance), and Kubernetes is the focus of section three: architecture and RBAC, workload identity through OIDC on EKS and AKS, admission control with CEL, OPA Gatekeeper and Rego, and runtime security with Cilium, Falco and KubeArmor.
Nine of the course’s 19 labs focus on containers, supply chain and Kubernetes, and students pick AWS or Azure for the cloud labs. It runs five days live or 38 hours on demand and prepares you for the GIAC Cloud Security Automation (GCSA) certification. As listed on its site in October 2026, OnDemand costs $8,780. That price makes it a fit for employer-funded training rather than self-funded study.
Best for: Enterprise security and DevSecOps teams with a training budget and a need for a GIAC credential.
6. Antisyphon Training — Two Day Attacking And Defending Kubernetes Class By Jay Beale
Antisyphon Training, the training company connected to Black Hills Information Security, runs Attacking and Defending Kubernetes with Jay Beale, creator of the Peirates attack tool and the Bust-a-Kube CTF cluster. The 16 hour class spends more than half its time in a live lab, and every attack exercise is paired with a defensive one. Topics include building a container from scratch, container breakouts, attacker persistence hidden in image layers, RBAC flaws, privilege escalation through node filesystems, secrets and service account exposure, Pod Security Standards and Kyverno, and network segmentation. It closes with a multi-stage CTF.
As listed on its site in October 2026, the next session runs at Wild West Hackin’ Fest Mile High in February 2027, priced from $825 to $2,745. For a shorter entry point, Cory Sabol’s PECSEC on demand course on container escapes costs $105 for lifetime access and includes twelve months of Antisyphon Cyber Range access.
Best for: Pentesters and defenders who want live offensive training at a lower price than most conference classes.
7. Killer Shell — CKS Simulator With Two 17 Scenario Environments
Killer Shell builds the exam simulators the Linux Foundation hands out with its Kubernetes exams. The CKS simulator offers two environments, CKS-A and CKS-B, with 17 scenarios each, plus detailed solutions. Each session gives you a cloud-hosted remote desktop for 36 hours, and you keep the questions and solutions after it ends, so you can review every task you got wrong.
If you buy the CKS exam, two sessions are already included. As listed on its site in October 2026, buying directly costs $39.99 for both sessions. For unlimited practice, its partner platform Killercoda hosts free browser-based scenarios built for CKS preparation and general Kubernetes security study, which work well between simulator runs.
Best for: CKS candidates who want a realistic, timed rehearsal before exam day.
8. Synacktiv — Kubernetes Intrusion Tactics And Three Day Kubernetes Forensics
Synacktiv is a French offensive security firm with offices in Paris, Toulouse, Lyon, Rennes, Lille and Bordeaux, and it is one of the few vendors that teaches both breaking into clusters and investigating them afterward. Kubernetes Intrusion Tactics is a two day, 14 hour course split 30% theory and 70% practice. Day one covers architecture, attack surface, reconnaissance, authentication and authorization. Day two covers pod templates and controllers, container escapes and lateral movement, finished on a vulnerable cluster. It is listed at 2,500 euros excluding VAT.
Kubernetes Forensics is a three day, 21 hour intermediate course listed at 3,000 euros excluding VAT. It covers evidence collection from audit logs and checkpoints, filesystem and memory analysis, network and DNS forensics and syscall capture, and ends with a hands-on incident response exercise. Synacktiv also runs a five day Cloud Intrusion Tactics course spanning AWS, Azure, GCP and Kubernetes.
Best for: European red teams, SOC and CERT analysts who need Kubernetes intrusion or forensics skills.
9. Sysdig — Free Falco 101 Runtime Security Course With A Lab Assessment
Sysdig created Falco, the CNCF runtime threat detection project that shows up in the CKS curriculum, SANS SEC540 and most Kubernetes defense courses on this list. Its free Falco 101 course on the Sysdig learning portal is the most direct way to learn the tool from the people who built it. Modules cover what runtime security is, installing and configuring Falco, event sources, writing rules, tuning rules with exceptions, alerting and the response engine.
After the opening lessons, the course moves into hands-on practice in real scenarios and ends with a final lab assessment. The modules add up to a little under six hours. It pairs well with a CKS course, since the runtime security domain is worth 20% of that exam, and with any blue team role that has to detect container escapes in production.
Best for: Defenders who need runtime detection skills for containers and Kubernetes at no cost.
10. Kubernetes Goat — Free Open Source Cluster With 22 Vulnerable Scenarios
Kubernetes Goat is an intentionally vulnerable Kubernetes environment built by security researcher Madhu Akula and released under the MIT license. You deploy it into your own cluster and work through 22 scenarios that cover common Kubernetes attack paths and misconfigurations, with documentation that explains each one. The GitHub project has close to 6,000 stars, and security vendors use it to demo their tools.
It is not a course with an instructor or a certificate, which is why it sits at the end of this list. It is still one of the best free resources for container security training: run it after a CKS or CCNSE course to practice the attacks you just learned to defend against, or use it to run an internal team workshop at no cost.
Best for: Self-learners and teams who want free, self-hosted offensive practice.
How To Choose A Kubernetes Security Training Provider
Do You Need A Certification Or Just The Skills?
If a job posting or a client contract asks for a Kubernetes security certification, the CKS is the one most people recognize, with the KCSA as a starting point. If you need a practical credential that tests offensive skills, the CCNSE fills that gap, and SANS GCSA fits teams already invested in GIAC. If no one is asking for a certificate, a private class from ControlPlane or Synacktiv will usually teach more per day.
Is The Training Offensive, Defensive Or Both?
Read the syllabus. CKS prep courses lean defensive: hardening, policy and detection. ControlPlane, Antisyphon and Practical DevSecOps teach both sides, and Synacktiv’s intrusion course is attacker first. Pentesters should pick a course that includes container escapes, RBAC abuse and lateral movement. If your work extends to cloud accounts as well as clusters, compare these against our list of top cloud penetration testing certifications.
How Much Hands-On Lab Time Is Included?
Kubernetes security is learned at the command line. Check how many labs a course has, how long lab access lasts and whether labs run in the browser or need your own cloud account. LFS260 labs, for example, expect you to provide a cloud account or VirtualBox, while KodeKloud, Practical DevSecOps and Killer Shell host the environment for you.
What Is Your Budget And Format?
Costs range from free (Kubernetes Goat, Falco 101, Killercoda) to a few hundred dollars (KodeKloud, LFS260, the CKS exam) to several thousand for live classes from SANS, the Linux Foundation and Synacktiv. Teams of five or more are often better served by a private class, where the instructor can tailor labs to the clusters you actually run.
Frequently Asked Questions
Is The CKS Exam Hard?
It is demanding. The CKS is a two hour, hands-on exam on live clusters, and you must already hold the CKA. Time pressure is the main challenge, so most candidates combine a structured course like KodeKloud or LFS260 with the two Killer Shell simulator sessions included with the exam.
What Is The Difference Between KCSA And CKS?
The KCSA is an associate level, 90 minute multiple choice exam that tests your understanding of Kubernetes and cloud native security concepts, and it has no prerequisite. The CKS is a professional level, performance based exam where you configure and secure real clusters, and it requires the CKA. Many people take the KCSA first, then work toward the CKS.
Can I Learn Kubernetes Security For Free?
Yes. Kubernetes Goat gives you 22 vulnerable scenarios to attack in your own cluster, Sysdig’s Falco 101 teaches runtime detection with hands-on labs, and Killercoda hosts free browser-based CKS practice scenarios. Free resources build real skills, but you will need paid training or an exam if you want a recognized certificate.
Conclusion
For most engineers, the path through the top Kubernetes security training providers starts with the Linux Foundation’s CKS, prepared with KodeKloud and Killer Shell. Teams that need deeper offensive skills should look at ControlPlane, Antisyphon or Synacktiv, and practitioners who want a practical certification that covers attacks should consider Practical DevSecOps. Add free container security training from Kubernetes Goat and Sysdig to keep your skills sharp between courses.
Whichever you choose, pick the course whose labs look most like the clusters you run. If you want hands-on practice beyond Kubernetes, our roundup of top cyber ranges and hands-on security training platforms is a good next step.
