Secure IT Infrastructure — The Foundation of Your Cyber Resilience

Networks, servers, endpoints, directory services such as Active Directory, and cloud environments form the backbone of modern organizations. Yet these complex infrastructures often expose unintended attack surfaces. Misconfigurations, insufficient system hardening, and weak authorization concepts remain among the most common and most critical security weaknesses.

Infrastructure Penetration Testing simulates real-world attacks against your internal and external infrastructure to uncover technical vulnerabilities before they can be exploited. CERTAINITY combines automated security tools with in-depth manual testing performed by experienced specialists — delivering practical, evidence-based, and actionable results.

We make your infrastructure measurably more secure — through realistic attack simulations, detailed analysis, and practical recommendations.

Our Assessment Areas at a Glance

Assessment of internet-facing systems such as VPN gateways, web servers, and exposed services through active scanning, manual penetration testing, and post-exploitation scenarios.

An internal infrastructure assessment simulates an attacker with network access. This includes identifying vulnerabilities across internal systems, services, and applications, performing attacks such as spoofing and password cracking, and evaluating your network segmentation and tiering concepts through internal segmentation testing.

Security assessment of employee workstations and business-critical servers, focusing on privilege escalation, data exfiltration, and system compromise.

Assessment of Active Directory configurations, permissions, and attack paths — from a standard user account through to Domain Administrator privileges.

Security assessment of AWS, Microsoft Azure, and Google Cloud Platform environments, including IAM concepts, cloud configurations, and publicly exposed resources.

Testing for container escape vulnerabilities, excessive privileges, and insecure cluster configurations — ideal as a complement to application or cloud security assessments.

Evaluation of approval and authorization concepts, environment isolation, and the integration of security controls into your software delivery pipelines.

Our assessments are modular and based on realistic attacker models—whether Black Box, Gray Box, or White Box testing. You’ll receive a prioritized list of findings and recommendations that are clearly documented and ready for implementation.
