CREST Certified Penetration Testing

Penetration testing is a form of ethical hacking. It is a technical security assessment of an organisation’s applications and supporting infrastructure,
undertaken by vetted and skilled security consultants with the authorisation and support of the organisation.

Through simulation of latest cyber attacker technology and techniques, trained digital specialists mimic the activity of online criminals to assess the strength of your infrastructure.

Scenario based pen testing simulates a digital attack, allowing businesses to identify and eliminate exploitable vulnerabilities before an external breach occurs. Testing can be applied to any number of application systems, Application Programming Interfaces (APIs), frontend/backend servers and inputs that may be vulnerable to a code injection attack.


Our processes and techniques meet the highest industry standards that guarantee quality and consistency in everything we do.

What does a Penetration Test do?

Penetration testing simulates cyber attacks against NAS, cloud-based digital infrastructures and applications. A controlled and secure system investigation by qualified professionals can uncover areas of vulnerability for a code injection attack against your systems.

How long does a Penetration Test take?

Typically, penetration testing will take between 1-3 weeks. However, this will vary depending on a number of factors including the size of engagement, the type of pen testing being carried out and the number of systems that are being tested.

How much does a Penetration Test cost?

The cost of penetration testing is again dependent on the size of engagement, the type of penetration testing you require, the number of projects and the resolution of potential vulnerabilities that are located within your organisation's infrastructure.

Why do we need a penetration test?

While penetration testing allows organisations to identify weaknesses, it can also be used to test an organisation's security policy, employee security awareness, compliance requirement adherence and your organisation’s ability to respond to security incidents.

How often should I get a penetration test?

This is dependent on several considerations including business size, infrastructure and budget availability. However, pen testing should be carried out as often as possible to keep up with evolving cyber threats and to ensure newly-added systems or applications are secure.

Types of CREST penetration testing: Which service is best for you?

Penetration testing can be conducted with testers having varying degrees of knowledge of your environment. Here are some of the most common terms you may encounter:

Blind testing or black box penetration testing:

Testers are only given basic information, such as the target business. This is the most realistic method of penetration testing, allowing your business to understand in real time how an infrastructure attack would occur. 

Due to the nature of blind testing, it can take longer to complete than other forms of testing. This is because with no information on your application structure, source code or software architecture, testers must conduct detailed reconnaissance of the application and its infrastructure to identify potential attack vectors.

Targeted testing or white box penetration testing:

This relies on full communication between the tester and security personnel, which often proves invaluable as a source of training for IT security teams. Real time feedback provides an education on the methods and technologies attackers use.

Prior knowledge enables testers to complete attack simulations more effectively as it eliminates the effort normally required for conducting reconnaissance. Testing can be more detailed because simulated system intrusion means that multiple potential vulnerabilities can be identified.

Double blind testing:

With this form of testing, security personnel and internal teams are given no prior knowledge of the impending simulated cyber breach attempt. This means theyare given no time to bolster digital defences, thus matching a real-world scenario.

Grey box penetration testing:

Combining both white box and black box penetration testing, grey box testing gives attack simulators partial knowledge of your infrastructure. This allows testers to focus on target areas and identify even the most hidden infrastructure vulnerabilities.
