Grey-box internal penetration testing, vulnerability analysis, incident response simulation, access control validation, and ISO 27001–aligned security recommendations.
The Challenge
NIBE, a multinational provider of sustainable energy solutions, needed to secure its internal network infrastructure against unauthorized access, sensitive information exposure and misconfigurations, and to prepare for advanced attack scenarios.
Engagement Approach
A grey-box penetration test using MITRE ATT&CK, OSSTMM and ISO 27001.
- Initial access testing to identify realistic attack entry points.
- Privilege escalation and lateral movement to test how far an intruder could go.
- Defense evasion to assess detection capabilities.
- Credential harvesting and network sniffing to evaluate exposure risks.
- Detailed reporting with remediation guidance and best-practice recommendations.
Results & Impact
- Critical vulnerabilities remediated, including one that allowed a low-privilege user to control the entire Active Directory.
- Improved incident response through simulations.
- Stronger access controls reducing unauthorized access risk.
- Alignment with ISO 27001 best practices.
Penetration testing is more than a compliance exercise — by exposing critical vulnerabilities and simulating real-world attacks, NIBE built a stronger, more resilient framework for ongoing security and compliance.
