Enhance Your Cybersecurity with Expert Internal Penetration Testing & Active Directory Security

Who Am I?

I am a seasoned internal penetration tester and IT-security engineer with a specialized focus on Active Directory security. My unique expertise lies in understanding both sides of the cybersecurity equation—offense and defense. This dual perspective empowers me to not only identify vulnerabilities but also recommend comprehensive solutions and create effective detection rules.

Why Choose My Services?

Comprehensive Vulnerability Assessment:
With my deep knowledge of attack methodologies, I conduct thorough internal penetration tests to uncover hidden vulnerabilities within your Active Directory environment. From privilege escalation pathways to lateral movement opportunities, I leave no stone unturned.

Expert Remediation Recommendations:
Identifying vulnerabilities is only half the battle. Leveraging my defensive expertise, I provide actionable recommendations to close security gaps effectively. Whether it's configuring Group Policies correctly, enhancing password policies, or deploying advanced security features, I guide you every step of the way.

Proactive Threat Detection:
Beyond remediation, I help you stay one step ahead of attackers by developing custom detection rules tailored to your environment. These rules enable early detection of potential breaches, allowing for swift incident response and minimizing damage.

Holistic Security Enhancement:
My services go beyond Active Directory security. I offer a holistic approach to fortifying your entire IT infrastructure, ensuring that all potential entry points are secured and monitored.


Don't wait for a breach to expose your vulnerabilities.
Contact me today to discuss how we can enhance your cybersecurity posture.

Kind regards,
Dennis Barnekow
