Course overview

The Purple Teaming for Blue Teams course is built specifically for Blue Team Practitioners who want to validate detection coverage across Microsoft and open-source SIEMs. You'll gain hands-on expertise to:

✓ Plan and execute safe, effective purple team exercises in your own environment

✓ Simulate real attacker techniques (MITRE ATT&CK) and immediately test your detections

✓ Analyse detection gaps across Microsoft Sentinel, Defender XDR, and open-source tools

✓ Collaborate with red team tactics to continuously strengthen your blue team capabilities

By the end, you'll have the practical skills and methodology to run ongoing purple team programs that measurably improve your organisation's detection and response effectiveness.

Who this course is for

You're a Blue Team Practitioner (Detection Engineer, SOC Analyst, Threat Hunter, or Security Engineer) who wants to validate and strengthen your actual detection coverage. This course is built for you if you want to:

✓ Move from assuming your detections work to continuously proving and improving them

✓ Run practical purple team exercises in Microsoft Sentinel, Defender XDR, and open-source SIEMs

✓ Bridge the gap between red team simulations and real blue team effectiveness

✓ Focus on detection engineering and visibility rather than just offensive techniques

In short: if you're a blue teamer who wants to validate that your detections actually catch real attacks, this course is for you.

What you'll learn

By the end of this Purple Teaming for Blue Teams course you will be able to:

✓ Design and execute structured purple team exercises tailored for blue team outcomes

✓ Simulate attacker techniques across the MITRE ATT&CK framework and test detection logic

✓ Analyse detection results and identify coverage gaps in Microsoft Sentinel, Defender XDR, and open-source SIEMs

✓ Convert purple team results into improved detections, analytics rules, and hunting queries

✓ Establish repeatable purple team programs and metrics to measure detection maturity

✓ Foster collaboration between blue and red teams to build more resilient defences

Key course takeaways

✓ Run effective purple team exercises that directly improve your detection coverage

✓ Validate and strengthen detections across Microsoft Sentinel, Defender XDR, and open-source SIEMs

✓ Identify and close critical visibility gaps before real attackers exploit them

✓ Build a continuous detection improvement program based on real attack simulations

✓ Measure and demonstrate meaningful improvements in your security detection posture

✓ Become the Blue Team leader who turns purple teaming into a powerful capability for your organisation

Things you need to know

What are the prerequisites for this course?

There are no prerequisites. The course teaches purple teaming methodology from first principles. Familiarity with detection engineering, KQL, and MITRE ATT&CK will help you move faster, but neither is required. Every technique and tool is explained at first use.

What are the device requirements?

A device with a modern browser. For hands-on exercises, a lab environment with a Windows VM, a Linux VM, and access to a Microsoft 365 E5 developer tenant with Sentinel. The course walks you through setup and provides Atomic Red Team and Caldera installation guides.

How will the course benefit your career?

Purple teaming is how mature security teams prove their detections work. Organisations need people who can execute ATT&CK techniques safely, validate detection coverage, close gaps, and report the results. This course gives you the methodology, the tool proficiency, and the program framework to lead that capability.

Purple team skills are increasingly a requirement for senior detection engineering, security architecture, and SOC leadership roles.
