Penetration Testing Services

Independent, CHECK & CREST accredited security testing to identify
exploitable weaknesses and support regulatory assurance.

Penetration testing in practice

Penetration testing is a controlled security assessment designed to identify exploitable weaknesses across networks, applications and supporting infrastructure before they can be used in a real attack.

Delivered by experienced security specialists, penetration testing goes beyond automated scanning to simulate real-world attack techniques and assess how effectively your organisation can prevent, detect and respond to cyber threats.

Typical weaknesses identified through penetration testing include:

  • Inadequate or improper configuration
  • Hardware or software flaws
  • Operational weaknesses in processes or technical countermeasures
  • Employees’ susceptibility to phishing and other social engineering attacks

The outcome is clear, prioritised insight that helps organisations reduce risk, support compliance, and provide assurance to auditors and regulators.

What should you expect from our penetration testing?

Our penetration testing engagements are designed to give you a clear, realistic view of how your systems could be compromised and what that means for your organisation. We identify potential entry points, carry out controlled exploitation, and assess access to sensitive data and critical systems.

Where weaknesses are found, we evaluate the potential for privilege escalation and wider impact. Every engagement concludes with clear reporting and practical remediation guidance, helping your teams prioritise fixes, reduce risk and demonstrate assurance.

Frequently asked questions

Penetration testing cost depends on the scope, complexity and systems being tested. Factors such as the number of applications, cloud services, network size and compliance requirements all influence pricing. We provide clear, tailored quotes based on your environment and risk profile, helping organisations budget confidently.

Penetration testing pricing is influenced by the type of testing required, the size of your environment, regulatory obligations and the level of assurance needed. For example, CREST and CHECK-accredited testing for regulated systems may require additional governance and reporting. During scoping, we ensure you receive appropriate coverage without unnecessary cost.

For clearly defined environments, we can provide fixed-price penetration testing following a short scoping session. This allows organisations to control costs while ensuring testing remains aligned to risk and compliance needs.
