How the penetration testing service helps
Evaluate your readiness against real-world attacks
During penetration testing, our experts mimic real-world attacks by looking for ways to circumvent your security systems and data using common tools and techniques.
We then provide a comprehensive report, helping you to determine:
- Where your vulnerabilities lie – including how well your systems tolerate real-world attacks, and how successfully you detect and respond to them
- What impact these vulnerabilities may have – and how likely they are to be exploited
- What actions you can take to improve your security posture
How the service works
The penetration testing service process involves the following steps:
- Performing reconnaissance
- Identifying vulnerabilities, exploring vulnerabilities, escalating privileges, gathering information, creating pivot points
- Cleaning up
- Reporting
Conduct varying tests according to your needs and budget
Because this is a flexible service, we offer varying scope and depth of penetration testing, making the service cost-effective for you. Our service could range from a straightforward evaluation of your external networks, to many hours of involved on-site manual testing.
Alternatively, you may simply be looking to have the security of an individual system or application tested before it is deployed, or you may be interested in the wider security of your network.
Either way, we can adapt our testing schedules to suit you.
Before testing begins, we can advise you on the level of service you are likely to need.

What information would you need to provide?
Different forms of penetration testing mean you need to provide different levels of information about your systems. These include:
- White box testing – where you provide full network information
- Grey box testing – where you allow the attacker user-level privileges
- Black box testing – where you provide no privileged information
Typically you will be required to provide information such as IP ranges, domains, URLs of applications, key systems and applications, and IP addresses and systems that should be avoided.
