Network Infrastructure Penetration Testing
Is your network secure against attacks? Network infrastructure penetration testing helps detect and neutralise vulnerabilities in IT systems before they are exploited by hackers. We simulate real-world attacks in a controlled environment and provide detailed recommendations to improve your security posture.
Benefits of Network Penetration Testing
Detection of critical security gaps
– we test servers, network devices, firewalls and domain controllers for vulnerabilities.
Protection against external and internal threats
– we perform tests from the perspective of both internet-based attackers and malicious insiders.
Prevention of unauthorised access
– we evaluate whether unauthorised users can access internal networks or take control of devices.
Regulatory and standards compliance
– our tests help meet requirements such as ISO 27001, NIST, GDPR and PCI-DSS.
What Is Network Infrastructure Penetration Testing?
Network penetration testing involves simulating cyberattacks to identify security weaknesses and assess their potential impact on the organisation. We assess both external networks (public-facing systems)
and internal infrastructure (corporate LANs, VPNs, Active Directory environments).
During the assessment, we check:
- Vulnerability scans and misconfigurations – identifying exposed services, weak passwords and improperly secured assets.
- Active Directory attacks – assessing Windows domain environments for Kerberoasting, Pass-the-Hash, and weak password policies.
- Firewall and IDS/IPS protection – verifying that security systems detect and block malicious traffic.
- Traffic interception and MitM attacks – testing resistance to packet sniffing, spoofing and session hijacking.
- Network segmentation and isolation – evaluating whether critical systems are separated from standard IT infrastructure.
Our tests provide a comprehensive view of your network’s security and help eliminate high-risk vulnerabilities.
We rely on industry-standard tools and methodologies aligned with global best practices:
- Nmap & Masscan – network scanning and identification of open ports and running services.
- Metasploit – automated exploitation of known vulnerabilities and simulation of attacks.
- BloodHound & CrackMapExec – Active Directory reconnaissance, configuration analysis and privilege escalation path discovery.
- Wireshark & Ettercap – traffic interception, packet analysis and anomaly detection.
- Burp Suite & OWASP ZAP – web application vulnerability testing within the network.
Our methodology follows PTES, NIST SP 800-115, and the OWASP Network Security Testing Guide.
Frequently Asked Questions
Can these tests disrupt my infrastructure?
No – all tests are carried out in a controlled and safe manner to avoid impacting system availability. We can adjust the level of intrusiveness to match your organisation’s requirements.
Do you test both external and internal networks?
Yes, we assess both public-facing systems and internal networks to evaluate potential threats from employees or intruders.
Which organisations should conduct network penetration tests?
Any company with an IT infrastructure – especially those processing personal, transactional, or business-critical data – should regularly assess their defences.
How often should penetration testing be conducted?
We recommend testing at least once a year and after any significant infrastructure update or deployment of new services in the network.
