Penetration Testing

Think You're Secure? Let's Prove it.

Regular penetration testing, sometimes known as ethical hacking, is a mainstay of security evaluation programmes with the goal of mitigating cyber risk.

Faced with the triple challenge of rising cyber threats, mounting public interest in data safeguarding and tough new regulations, organisations are taking no chances when it comes to testing – and demonstrating – their resilience to attacks.

Identifying your organisation’s vulnerabilities by using techniques employed by real-world cyber criminals will set you on the right course to accurately evaluating risk and, where necessary, choosing the right remedial solutions.

Why Conduct Regular Penetration Testing?

Penetration Testing Phases

The penetration testing team and the client work together to define the scope and objectives of the testing. This involves identifying the systems, applications, and networks to be tested, as well as the testing methods and tools to be used.

The penetration testing team gathers information about the target system or network, including IP addresses, open ports, operating systems, and applications. This information is typically gathered through passive or active reconnaissance techniques.

The team uses vulnerability scanning tools to identify known vulnerabilities in the target system or network. This step helps the tester to understand the level of risk associated with each vulnerability.

The team attempts to exploit the identified vulnerabilities in the target system or network. This involves using various attack techniques to gain access to the system or network, such as SQL injection, weak authentication, or brute-force attacks.

Once the team has gained access to the target system or network, they attempt to escalate privileges, install backdoors, or access sensitive data. This step is critical in determining the overall security posture of the target system or network.

The penetration testing team documents the findings and recommendations from the testing exercise. This includes a detailed report on the vulnerabilities identified, the methods used to exploit them, and recommendations for remediation.

Types of Penetration Testing

Internal Penetration Testing

This assesses the threat of both deliberate and accidental breaches from hackers and malicious or negligent insiders with access to your systems. Often deemed low-risk, internal attacks can actually pose a substantial threat to an organisation.

Why Internal Penetration Testing Matters?

Internal penetration testing helps uncover risks from within your network whether caused by malicious insiders or misconfigurations. It tests how far an attacker could go after gaining access, validates your internal security controls, and supports compliance with ISO 27001, PCI DSS, NIS2, and more. Most importantly, it strengthens your ability to detect and contain threats before they cause serious damage.

External Network Penetration Test

External network penetration testing is a type of penetration testing that focuses on evaluating the security of a network infrastructure. This test identifies the vulnerabilities of your computer systems through their exposure to the Internet.

Why External Network Penetration Testing Matters?

It simulates real-world attacks from outside your organisation to assess how well your perimeter defences hold up. This helps uncover weak points, validate patching and configuration practices, and ensure that exposed services are not creating entry points for threat actors. It’s also key for meeting compliance requirements and demonstrating proactive risk management.

Web Application Penetration Testing

A web application penetration test is a type of security assessment that involves identifying and exploiting vulnerabilities in web-based applications. The correct choice of test if you wish to ensure that your websites, webshops, intranets, extranets and web-based applications are secure.

Why Web Application Penetration Testing Matters?

It helps uncover risks like SQL injection, XSS, and authentication flaws, protecting sensitive data and preventing unauthorised access. This type of testing ensures your applications align with OWASP Top 10, PCI DSS, and GDPR requirements, while also strengthening your architecture through real-world attack simulations. Ultimately, it reduces the risk of downtime, data loss, and reputational damage demonstrating a strong commitment to secure digital experiences.

Mobile Application Penetration Test

A mobile application penetration test assesses the security of your mobile apps by identifying vulnerabilities that could allow attackers to access sensitive data or systems. It also evaluates the web services your app communicates with, helping ensure your entire mobile ecosystem is secure.

Why Mobile Application Penetration Testing Matters?

This testing identifies vulnerabilities in both the app and the back-end services it communicates with. It helps uncover issues such as insecure data storage, poor authentication, exposed APIs, and weak encryption. It helps ensure your mobile apps are secure, compliant, and resilient against real-world threats.
