Course overview

The Offensive Security for Defenders course is built specifically for Security Practitioners who want to detect campaigns, not just alerts. You'll gain practical, hands-on expertise to:

Simulate real-world attacker techniques using MITRE ATT&CK and living-off-the-land methods
Think like a red teamer to identify blind spots in your current detection and prevention controls
Improve threat detection engineering by understanding how attacks actually work
Translate offensive knowledge into stronger defences, hunting, and response capabilities

By the end, you'll have the offensive mindset and technical skills to proactively find and close detection gaps, making your organisation significantly harder to compromise.

Who this course is for

You're a Security Practitioner (SOC analyst, Detection Engineer, Threat Hunter, or Blue Teamer) who wants to move beyond triaging alerts to detecting full attacker campaigns. This course is built for you if you want to:

Develop an offensive security mindset to better understand and counter real adversaries
Learn how attackers operate so you can build more resilient detections and defences
Bridge the gap between red team tactics and blue team detection engineering
Significantly improve your ability to find stealthy, persistent threats in your environment

In short: if you're ready to detect campaigns, not just alerts, and become a much more effective defender, this course is for you.

What you'll learn

By the end of this Offensive Security for Defenders course you will be able to:

Understand and replicate common attacker techniques across the MITRE ATT&CK framework
Simulate realistic attack scenarios to test and improve your detection capabilities
Identify detection gaps and blind spots by thinking like a red teamer
Build high-fidelity detections and hunting queries based on real campaign behaviour
Apply offensive knowledge to enhance threat hunting, incident response, and detection engineering
Develop a campaign-aware defensive strategy that focuses on adversary behaviour rather than isolated IOCs

Key course takeaways

Develop a true offensive mindset that makes you a far more effective defender
Master the ability to detect full attacker campaigns instead of just individual alerts
Proactively identify and close detection gaps before real attackers exploit them
Translate red team techniques into stronger blue team detections and hunting playbooks
Significantly improve your organisation's resilience against sophisticated, stealthy threats
Become the defender who understands attackers better than they understand your environment

Things you need to know

What are the prerequisites for this course?

There are no prerequisites. The course teaches offensive concepts from a defender's perspective. Familiarity with KQL, Microsoft Sentinel, and Defender XDR will help you move faster, but neither is required. Every tool and technique is explained at first use.

What are the device requirements?

A device with a modern browser. Access to a lab environment for running offensive tools (the course walks you through setup). You will also benefit from a Microsoft 365 E5 developer tenant for detection development.

How will the course benefit your career?

Defenders who understand offensive operations are dramatically more effective at detection engineering, threat hunting, and incident response. This course gives you the attacker's perspective so you can anticipate campaign patterns, build detections that survive tool rotation, and investigate incidents at the campaign level rather than the alert level.

Offensive understanding is increasingly a prerequisite for senior detection engineering, threat hunting, and security architecture roles.
