Identify exploitable weaknesses before attackers do.
Through controlled testing and expert analysis, penetration testing assesses where your systems, applications and infrastructure may be exposed, with clear recommendations to reduce risk.

## 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 insight into 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.
### Identify Security Weaknesses
Identify vulnerabilities across your systems, applications and infrastructure.
### Review Existing Security Controls
Assess how effectively your security measures protect your organisation.
### Support Compliance Requirements
Support customer requirements, cyber insurance applications and compliance objectives.
### Prioritise Improvements
Understand which security issues need attention first, based on risk and potential impact.
## What can we test?
Penetration testing can be scoped around your organisation's systems, applications and infrastructure, based on your risks, requirements and priorities.
### Applications & Digital Services
Websites, customer portals, mobile applications, APIs and integrations.
### Infrastructure & Networks
Internet-facing systems, internal networks, servers, devices, Wi-Fi environments and remote access services.
### Cloud Environments
Cloud-hosted applications, services, platforms and supporting infrastructure.
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
## Considering a Penetration Test?
Whether you need to meet customer requirements, support a cyber insurance application or understand where your business may be exposed, we're here to help.
