Penetration testing of infrastructure
An infrastructure penetration test is a controlled simulation of a cyberattack targeting your servers, network devices, operating systems, and services. The goal is to identify vulnerabilities that a real attacker could exploit to breach your network, escalate privileges, or access sensitive data.
Non-binding consultationExternal Penetration Test
We test system configurations, network segmentation, access management, password policies, and other security mechanisms. The output is a detailed report featuring discovered vulnerabilities, proof of their exploitability, and specific recommendations for remediation.
An external penetration test simulates an attack from the internet–that is, from the perspective of an attacker who has no access to your internal network.
We focus on everything accessible from the outside of your infrastructure: publicly accessible servers, email gateways, VPN concentrators, web applications, DNS servers, and other exposed services.
We look for misconfigurations, unpatched systems, weak encryption protocols, and other vulnerabilities that would allow an attacker to gain initial access to your organization. The test reveals how your company looks through the eyes of an attacker on the internet and shows where the defensive line needs to be strengthened.

Internal Penetration Test
An internal penetration test simulates a situation where an attacker is already inside your network–for example, after a successful phishing attack, compromise of an employee device, or exploitation of physical access.
We focus on network segmentation, Active Directory configuration, privilege management, shared network resources, and possibilities for lateral movement between systems.
We test how far an attacker can get from initial access to your organization’s most valuable assets–domain controllers, databases with sensitive data, or control systems. The result will show whether your internal defenses can stop or at least detect the attacker.
Cloud Penetration Test
A cloud environment penetration test verifies the security of your infrastructure running in the cloud–whether it is Microsoft Azure, Amazon AWS, Google Cloud Platform, or another provider.
We focus on the configuration of cloud services, Identity and Access Management (IAM), storage settings, network rules, data encryption, and the security of virtual machines and containers.
Misconfiguration of the cloud environment is among the most common causes of security incidents. We test whether your settings comply with best practices and whether an attacker can exploit excessive permissions, publicly accessible storage, or missing segmentation to breach your environment.
How does a penetration test work?
Initial Consultation
Together, we define the scope of testing, goals, and expectations. (1–2 days)
Planning and Preparation
We formalize the cooperation–signing of the NDA, contract, and Rules of Engagement. (1–3 days)
Test Execution
Active testing phase–a combination of automated tools and manual techniques. (5–15 days)
Analysis and Reporting
We thoroughly analyze all findings and classify them by severity (CVSS score). (3–5 days)
Presentation of Results
We present the results clearly–an executive summary for management and a detailed technical report for the IT team. (1 day)
Retesting
After the implementation of fixes, we perform repeat testing. (2–3 days)

What sets us apart
Specialized team, not subcontractors
We are not a consultancy firm that resells work. Every project is led directly by members of our team with full responsibility for the result.
Manual work, not just automated tools
Automated scanners detect known vulnerabilities. Logic errors, business-logic flaws, and exploit chains can only be uncovered by an experienced tester who thinks like an attacker.
Actionable outputs
The report is not an academic exercise. It is written so that your dev or ops team can start remediation immediately–with specific steps and links to resources.
Tailored scenarios, not templates
We build every project according to your environment, your risks, and your goals. We do not use off-the-shelf methodologies or generic templates.
Discretion and confidentiality
We sign an NDA before every project. All information and results remain exclusively between us and you.
Compliance with international standards
The methodology is based on OWASP, PTES, and NIST and is in compliance with NIS2 and the Cybersecurity Act–meaning it is recognized by regulators and auditors.
