Our Penetration Testing Process
We make it easy to work with us. Here’s a high-level overview of our streamlined pen testing process:
1.
Consultation
Reach out to us to begin the process. Our pre-sales team and Account Manager will collaborate with you to fully understand your testing requirements.
2.
Scope & Quote
We’ll draft a comprehensive Scope of Work, detailing the scope and pricing. Our PMO will then contact you to finalise testing dates and provide a Testing Consent Form for completion.
3.
Preparation
After confirming the testing dates, we assign a dedicated lead tester to your project. If necessary, we’ll arrange a pre-test call to discuss prerequisites and address any questions.
4.
Testing
Testing begins on the agreed dates, with continuous real-time updates on high-priority findings to ensure prompt risk management and resolution.
5.
Report & Debrief
After testing, the report undergoes QA and is sent to you. We then offer a debrief session, where you can review the findings and discuss next steps with the lead tester, ensuring you are fully informed and prepared.
The Importance of Penetration Testing
Penetration testing provides a snapshot of the current security profile of your organisation. Every organisation will have an IT environment of some kind, from basic internet access and e-mail to fully functional cloud and web-based applications, often with sensitive or valuable data being processed.
The implications of a cyber security compromise can severely threaten the stability and continuity of your organisation. Penetration testing is a proactive approach to data security that helps to maintain the confidentiality, integrity, and availability of data, thus supporting your organisation’s compliance with relevant data protection laws and regulations, and safeguarding its reputation and trustworthiness in the public eye.
Penetration testing is a critical component of your organisation’s data protection strategy, offering valuable insights into potential vulnerabilities within the IT infrastructure and providing a pathway for enhancing data security measures.
The MTI team who conducted the penetration testing services in our organisation were not only respectful but also an absolute delight to work with. Their exceptional professionalism made my job extremely easy, and I couldn’t have asked for better service. They delivered the results within the expected timeframe and exceeded our expectations. If we require any further penetration testing, it would be our pleasure to work with them again.

Penetration Testing FAQs
What is penetration testing?
Penetration testing (or pen testing) is a controlled cyber security assessment where ethical hackers simulate real-world attacks to identify vulnerabilities in your systems, networks or applications before criminals can exploit them.
At MTI, our penetration testing services uncover security weaknesses, validate existing controls and provide clear remediation guidance to reduce business risk.
Why is penetration testing important?
Penetration testing helps organisations identify exploitable vulnerabilities before attackers do. It reduces cyber risk, protects sensitive data and strengthens overall security posture.
Regular testing supports compliance requirements, improves incident readiness and demonstrates due diligence to customers, regulators and insurers.
What is the difference between penetration testing and vulnerability scanning?
Vulnerability scanning uses automated tools to identify known security weaknesses.
Penetration testing goes further. It involves skilled ethical hackers actively exploiting vulnerabilities to determine real-world risk, business impact and attack paths. Pen testing provides deeper analysis and prioritised remediation advice.
How often should penetration testing be carried out in the UK?
Most organisations should conduct penetration testing at least annually.
Testing should also be performed after significant infrastructure changes, cloud migrations, new application deployments or major updates. Some compliance frameworks require more frequent testing.
MTI can help define the right testing schedule based on your risk profile.
What happens during a penetration test?
A typical penetration testing engagement includes:
- Scoping and planning
- Reconnaissance and vulnerability discovery
- Controlled exploitation
- Risk validation
- Detailed reporting and remediation guidance
- Post-test debrief and report walkthrough
MTI ensures all testing is authorised, controlled and aligned with agreed rules of engagement.
What is CREST-accedited penetration testing?
CREST-accredited penetration testing is delivered by providers independently assessed for technical competence, quality processes and ethical standards. CREST is an internationally recognised accreditation body for cyber security testing companies.
As a CREST member and founding participant, MTI delivers penetration testing services aligned with CREST’s rigorous assessment standards.
Will penetration testing disrupt our business operations?
Professional penetration testing is designed to minimise disruption.
MTI carefully scopes testing activities, schedules high-risk activities outside business hours where necessary, and follows strict safety controls. While some testing may increase system load temporarily, we prioritise stability and business continuity.
How long does a penetration test take?
The duration of a penetration test depends on scope and complexity.
A small web application test may take several days, while a full internal and external network assessment may take one to two weeks. MTI provides a clear timeline during the scoping phase.
What is black box, grey box and white box testing?
These terms describe how much information testers receive:
- Black box testing – No prior knowledge of the system
- Grey box testing – Limited access or credentials provided
- White box testing – Full access and system knowledge
MTI helps determine the most appropriate approach for your objectives.
What will I receive after the penetration test
After testing, MTI delivers a detailed penetration testing report including:
- Executive summary for leadership
- Technical findings with evidence
- Risk ratings and business impact
- Clear remediation recommendations
We can also provide remediation validation testing where required.
What is NCSC CHECK penetration testing?
NCSC CHECK penetration testing is a UK government-approved scheme that certifies companies and individuals to conduct high-assurance security testing in line with National Cyber Security Centre (NCSC) standards. CHECK assessments are often required for public sector and critical national infrastructure organisations.
MTI employs accredited CHECK Team Leaders (CTLs) and CHECK Team Members (CTMs), delivering government-aligned penetration testing across the UK.
