Cyber Security Testing

Why cyber security testing makes a difference

Your business may have firewalls, antivirus and a SOC, but gaps still exist. Sophisticated attackers exploit those gaps. By simulating realistic attacks (targeting networks, web apps, cloud assets and even human behaviour), we help you understand exactly where you’re vulnerable.

When you know your attack surface, you can prioritise fixes, strengthen defences, meet compliance and protect your reputation.

Types of penetration testing

Our penetration testing methodology is never one-size-fits-all; it’s determined by the level of information shared with our testers beforehand. Closed box testing simulates a real-world external attacker with no prior knowledge of your systems, relying only on publicly available information to find vulnerabilities. In contrast, glass box testing provides our team with full knowledge, including source code and credentials, enabling a highly focused assessment to identify deeply rooted vulnerabilities. The intermediate approach, translucent box testing, uses partial knowledge, allowing for more targeted testing while still maintaining a degree of realism.

Internal penetration testing

Internal penetration testing examines your network, systems and applications from the perspective of an insider, simulating a compromised user or malicious employee. This involves assessing network segmentation and internal access controls, identifying unpatched software and misconfigurations, and performing lateral movement testing to see how far an attacker could pivot. We also evaluate internally hosted web apps and the security of workstations and servers to ensure all internal vulnerabilities are identified and addressed.

External penetration testing

Your external-facing infrastructure is the gateway to your organisation and the primary target for cyber criminals. External penetration testing (or perimeter testing) simulates real-world attacks originating from outside your network to identify vulnerabilities in these publicly accessible assets. We focus on analysing your internet-facing assets, including firewalls, web applications, email servers, VPNs, and publicly exposed APIs. This ethical hacking exercise proactively uncovers security flaws before they can be exploited, ensuring your first line of defence is robust enough to protect sensitive data and maintain business continuity.

Web application testing

Your web applications are access points for customers and sensitive data. Web application penetration testing is a specialised assessment that goes beyond surface checks, simulating real-world attacks to uncover security flaws stemming from insecure development. Our comprehensive methodology delves into the design and code to actively search for flaws like Cross-Site Scripting (XSS), database manipulation weaknesses, and insecure login/session management. We identify flaws in third-party libraries and check for improperly configured servers, ensuring your critical web assets are protected from a wide range of cyber threats.

Automated penetration testing

Automated testing leverages specialised software to efficiently scan complex IT environments, providing broad coverage and a quick initial security overview. These tools systematically identify known software vulnerabilities, missing patches, open ports, and common flaws like SQL injection and XSS. While automation offers speed and continuous monitoring at a lower cost, it is crucial to remember that it is not a replacement for manual penetration testing. It lacks the contextual understanding required to find complex, logic-based vulnerabilities that only skilled human testers can uncover.

How we work

First, we’ll work with you to define the scope: what systems, applications and assets matter most, and what risks concern you most. Then our specialist team applies a mix of methodology, including automated scans, manual review and adversarial simulation, tailored to your size and sector. After testing, you receive a clear, actionable report: we don’t just show what’s wrong, we help you fix it. Retesting and verification complete the loop, so you can track improvement.

We handle the complexity, you get clarity and direction. Simply get in touch to find out more.
