Helping you with
Penetration Testing Services
Penetration Testing, also known as pen testing or ethical hacking, is the process of testing a computer system, network or web application to find security vulnerabilities that an attacker could exploit. A penetration test can be used to assess the security of a system and identify any potential weak points that could be exploited by malicious actors.
Penetration Testing simulates different types of attacks, including SQL injection, denial of service (DoS), and man-in-the-middle (MiTM) attacks. By attempting to exploit vulnerabilities, penetration testing specialists can assess a company’s security measures and identify areas that need improvement.

Penetration testing FAQs
What is a network penetration test?
A network penetration test is a security assessment that identifies vulnerabilities in your organisation’s internal and external network infrastructure. It helps uncover weaknesses that attackers could exploit, such as misconfigurations, outdated software, and insecure network protocols.
What is a standard penetration test?
A standard penetration test is a controlled security test where ethical hackers simulate real-world cyber attacks to find and fix vulnerabilities in your systems, applications, or networks. It typically follows a structured approach to assess security risks and improve defences.
What is an external penetration test?
An external penetration test focuses on identifying vulnerabilities in internet-facing assets, such as websites, email servers, and cloud environments. This type of test helps protect against hackers attempting to breach your organisation from the outside.
What’s the difference between pen testing and vulnerability scanning?
Vulnerability scanning, sometimes called automated penetration testing, uses scanning software to methodically and simply scan for a list of known vulnerabilities. Penetration testing on the other hand uses in depth analysis and human ingenuity to uncover security flaws that can’t be found by vulnerability scanning alone. Automated testing and vulnerability scanning are an important part of your defences, such as helping regular patching, whereas a penetration test provides detailed reporting and remediation advice from cyber security experts. Penetration testing companies will use both tools in their arsenal to make sure your business is protected against cyber threats.
What is api penetration testing?
API penetration testing assesses the security of application programming interfaces (APIs) by identifying weaknesses in authentication, authorisation, and data handling. This helps prevent unauthorised access, data leaks, and API abuse.
What tools are used for penetration testing?
Penetration testers use a combination of automated and manual tools, including industry-standard software like Metasploit, Burp Suite, Nmap, and Nessus. These tools help scan for vulnerabilities, exploit weaknesses, and provide detailed reports on security gaps.
What is the difference between penetration testing and red teaming?
Penetration testing and red teaming are both cybersecurity assessments but differ in scope and objectives. Penetration testing focuses on identifying and exploiting vulnerabilities in a specific system, application, or network within a limited timeframe, providing a report with remediation steps. In contrast, red teaming simulates real-world attacks across an organisation’s entire security posture, including people, processes, and technology, to test detection and response capabilities over a longer period. While penetration testing helps organizations find weaknesses, red teaming evaluates how well they can withstand and react to sophisticated threats.
