Build a realistic enterprise security environment based on Microsoft technologies.
The Lab
Building an Enterprise Security Platform
Brunner Security Labs is a continuously evolving enterprise cybersecurity laboratory designed to demonstrate how modern Microsoft security technologies can be integrated into a cohesive and secure enterprise environment.
Rather than focusing on isolated products or individual security features, the lab documents how identity, endpoint protection, monitoring, governance and incident response work together as part of an enterprise security architecture.
Purpose
Why this lab exists
Modern cybersecurity is no longer about deploying individual security tools. Organizations need integrated security platforms that provide visibility, governance, detection and response across their entire IT environment.
The purpose of Brunner Security Labs is to create a realistic reference environment that demonstrates how these capabilities can be implemented using Microsoft 365, Microsoft Defender, Microsoft Sentinel, Microsoft Intune, Microsoft Entra ID and Microsoft Purview.
Every documented configuration is implemented, tested and explained through practical examples based on realistic enterprise security scenarios.
Objectives
What the lab is designed to achieve
The lab combines technical implementation, security architecture and structured documentation in one continuously developing environment.
2
Document security implementations using an architecture-first approach.
3
Demonstrate practical security measures aligned with ISO/IEC 27001, the NIST Cybersecurity Framework and Zero Trust principles.
4
Continuously expand the platform with additional security domains, detection use cases and incident response scenarios.
Scope
What you will find
The documentation covers the principal security domains required to build, operate and continuously improve a modern enterprise security environment.
Enterprise Foundation
ImplementedMicrosoft 365, Microsoft Entra ID, Microsoft Intune, SharePoint and Azure security services provide the technical foundation of the lab.
Identity & Access
ImplementedIdentity lifecycle, authentication, authorization, administrative roles and secure access to enterprise resources.
Endpoint Security
ImplementedDevice management, compliance policies, encryption, antivirus protection and endpoint detection and response.
Monitoring & Detection
In ProgressCentralized logging, Microsoft Sentinel, Microsoft Defender telemetry, KQL analytics and detection engineering.
Governance & Compliance
ImplementedInformation protection, sensitivity labels, compliance assessments, auditing and security posture management.
Incident Response & DFIR
PlannedIncident handling, investigation, evidence collection, forensic analysis and documented response procedures.

Continuous Development
An evolving enterprise security reference environment
Brunner Security Labs is an ongoing project. New security domains, Microsoft technologies, detection use cases and incident response scenarios are added as the platform evolves.
The documentation grows alongside the lab and reflects practical, validated enterprise security implementations rather than purely theoretical concepts.
Existing configurations are reviewed and refined as new requirements, technologies and lessons learned emerge. The lab therefore represents both a technical platform and a continuous security improvement process.
Future Roadmap
The next evolution of the lab
Brunner Security Labs is designed as a long-term enterprise security platform. Future development extends beyond implementing defensive security technologies and focuses on validating the effectiveness of the implemented security architecture through realistic attack simulation and continuous security validation.
Offensive Security
Planned activities include vulnerability assessments, penetration testing and adversary simulation against the laboratory environment. These exercises will validate the effectiveness of the implemented security controls and identify opportunities for continuous improvement.
Detection & Response Validation
Simulated attack scenarios will be used to verify Microsoft Defender, Microsoft Sentinel, detection rules, alerting, incident response procedures and digital forensic capabilities under realistic conditions.
Purple Teaming
The lab will evolve into a platform where offensive and defensive techniques are combined to continuously improve detection coverage, response procedures and overall security maturity.
Continuous Improvement
New Microsoft security capabilities, emerging threats and evolving enterprise security practices will be continuously incorporated to keep the laboratory aligned with modern enterprise environments.
