Penetration Testing

Vulnerability detection

By proactively detecting security weaknesses, you can prevent malicious actors from exploiting them, by fixing them before they get the chance.


Penetration testing aligns with security standards such as ISO 27001 and PCI DSS, which require that you adhere to regular testing in order to meet the standard and any regulatory requirements. The resulting reports provide evidence of compliance efforts and any improvements made based on test findings, to help you maintain compliance and avoid penalties.

Risk mitigation

By identifying and addressing vulnerabilities, you significantly reduce the risk of potential security breaches and data compromises. This proactive approach minimises the likelihood of unauthorised access, data loss, and service disruptions.

Protection against reputational and financial damage

Preventing data breaches is crucial due to the potential for fines under the General Data Protection Regulation 2018 and reputational harm from the perception that you have not been vigilant in protecting customer data. Understanding security weaknesses helps mitigate the risk of breaches.

Types of Penetration Testing

Our cyber security experts are ready to assess your internal and external networks, alongside other applications, to unveil security vulnerabilities. Discovering potential weaknesses in your organisation via penetration testing, empowers you to strategically allocate resources to fortify against future breaches.

Internal Testing

The strength of internal testing is the combination of manual scrutiny and comprehensive vulnerability assessments, working in tandem. The manual approach reveals security gaps within your IT systems, beginning from wired network connectivity and advancing to potentially compromising your domain. A subsequent vulnerability assessment then highlights any security shortfalls, from missing patches to system misconfigurations.

External Testing

This dynamic assessment covers both on-site and off-site vulnerabilities in your internet-facing systems, offering a comprehensive analysis of potential attack points. Gain insights into vulnerabilities within these systems and understand potential exploits for unauthorised access to sensitive information.

Application & API Testing

In addition to identifying software vulnerabilities and improving security, this service ensures seamless functionality and exceptional user experiences. From rigorous functional assessments to intricate API evaluations, we guarantee software excellence at every level.

Configuration & Code Reviews

Our experts meticulously examine your configurations and code, enhancing efficiency and identifying vulnerabilities. Our in-depth reviews elevate your software’s performance and.

Red/Blue/Purple Team Testing

Uncover vulnerabilities (Red), fortify defences (Blue), and achieve comprehensive insights (Purple) into your security posture. Our expert teams simulate real-world scenarios, ensuring your systems are resilient and strengthening your protection strategy.

Social Engineering

Our expert analysis and simulations expose vulnerabilities in human behaviour, fortifying your defences against phishing, scams, and data breaches. It enables you to navigate security risks effectively and bolster your security posture.

When Should Businesses Carry Out Penetration Testing?

Penetration testing is a ‘point in time assessment’, providing a snapshot of your security posture at the point of testing. As new security vulnerabilities are constantly being discovered and published, both penetration testing and vulnerability assessments should be conducted regularly. Most security specialists will recommend at least annual penetration tests, though there are other factors to consider:

If the answer is more than a year ago, even if there are no ongoing security changes, you should arrange a test.
Any time you make a non-trivial change to your infrastructure, Daisy advises that a penetration test is conducted to ensure you are aware of your vulnerabilities.
Some organisations have business or regulatory obligations to undertake more regular penetration testing. In this case, always follow the schedule provided by your compliance team.
