Infrastructure Testing

External Network Penetration Testing

External network penetration testing evaluates your internet-facing assets – such as web servers, firewalls, and mail systems – for vulnerabilities that could be exploited remotely. Attackers are constantly scanning the internet for weaknesses, making it essential to test these systems regularly.

Our tests mimic real-world attacks from the perspective of an unauthenticated external threat actor. We assess exposure, misconfigurations, outdated software, and common vulnerabilities, helping you identify and remediate issues before they’re exploited.

This service is essential for:

• • Organisations with public-facing infrastructure
  • Companies looking to reduce risk from remote attackers
  • Organisations obligated to carry out regular testing for PCI DSS or ISO 27001 compliance.

Internal Network Penetration Testing

Internal penetration testing assesses your organisation’s security posture from within, simulating a threat actor with internal access – such as a disgruntled employee, compromised device, or attacker who has breached your perimeter.

We explore lateral movement, privilege escalation, and access to sensitive systems to highlight flaws in segmentation and patching. Our aim is to assess what an attacker could do once inside your network – whether through phishing, stolen credentials, or bypassed perimeter controls.

This testing often reveals issues like over-permissioned accounts, flat internal networks, unmonitored legacy systems, and weak endpoint configurations. By replicating realistic attack paths, we help you understand how an initial foothold could escalate into full domain compromise or unauthorised access to critical data.

Wireless Penetration Testing

Wireless penetration testing focuses on assessing the security of your organisation’s wireless infrastructure. This includes Wi-Fi networks, access points, guest networks, and associated authentication methods.

Testing aims to uncover flaws such as weak encryption, insecure configurations, rogue access points, and risks from nearby unauthorised access. We evaluate whether attackers could exploit vulnerabilities to intercept traffic, gain unauthorised access to internal systems, or move laterally within your network.

Our assessment also considers the separation between corporate and guest networks, the strength of wireless authentication protocols (such as WPA2/3 Enterprise), and the risk posed by poorly managed devices or misconfigured controllers. This helps ensure that your wireless environment supports secure mobility without exposing your broader infrastructure to avoidable threats.
