About Penetration Testing

Penetration test, also known as pen test, is a controlled security assessment that identifies weaknesses across systems, applications and infrastructure.

We combine automated testing with expert manual techniques to assess your environment and simulate the methods an attacker may use to gain unauthorised access to systems, data or services.

As cyber attacks become increasingly automated and targeted, regular testing helps organisations understand how effectively their systems and security controls would withstand an attempted attack.

The assessment provides an evidence-based view of where your organisation may be exposed, the potential impact of those weaknesses and the actions needed to strengthen your security posture.

Trusted guidance from scoping to reporting

Grant McGregor partners with experienced cyber security specialists to help organisations plan, manage and understand penetration testing projects.

From initial scoping through to final reporting, we help you define what should be tested, interpret the findings and prioritise the remediation actions that matter most.

Why invest in Penetration Testing?

By simulating real-world attacks, penetration testing helps organisations uncover weaknesses in their defences and take action before they can be exploited.

Not sure what should be tested? We can help you decide what to include based on your systems, risks and requirements.

Is it time for a Penetration Test?

A pen test can help when you need confidence that your systems are secure, or evidence that appropriate security controls are in place.

You may need a pen test if you are:

Applying for or renewing cyber insurance
Being asked by customers to prove your security controls
Working towards ISO 27001 or other compliance requirements
Preparing for a tender or responding to a security questionnaire
Launching a new website, portal or application
Moving systems, data or infrastructure to a new environment
Reviewing your cyber security as part of an annual assessment
Looking for a specialist assessment of where your business may be exposed
