Testing services

Choose the right testing engagement.

Different assessment methods answer different questions. The engagement scope should reflect your environment, objectives and operational constraints.

Human-led testing

Go beyond an automated scan.

Automated tools help identify possible weaknesses. A penetration test adds controlled investigation, attack-path analysis and human judgement within agreed boundaries.

  • Validate exploitability

    Investigate whether a weakness can be used in practice and under which conditions.

  • Follow attack paths

    Examine how separate weaknesses and controls interact across the agreed scope.

  • Explain business impact

    Connect technical evidence with the systems, data and operations that may be affected.

Our approach

From testing to practical improvement.

A structured process that turns technical findings into meaningful, prioritised actions for your organisation.

  1. Objectives

    Agree the questions, systems and outcomes.

  2. Authorisation

    Confirm scope, permissions and rules of engagement.

  3. Testing

    Conduct the agreed assessment activities.

  4. Reporting

    Present findings, evidence and business context.

  5. Remediation planning

    Prioritise practical improvement actions.

  6. Retesting

    Validate agreed fixes where included in the engagement.

Deliverables

Evidence for technical teams and decision-makers.

Clear, structured outputs that help you understand the risks, take action and demonstrate progress.

  • Executive findings

    A clear summary of important findings and their implications.

  • Technical evidence

    Detailed findings and supporting evidence appropriate to the assessment.

  • Prioritised actions

    Recommendations to support remediation planning.

  • Assurance context

    Connect findings with the agreed risk and assurance objectives.

Assurance goals

What is driving your assessment?

Start with the questions your organisation needs to answer. Agree the testing scope around your technical risks and assurance objectives.

Testing supports your wider assurance programme. It does not establish compliance on its own.

The bigger picture

Connect technical evidence with governance.

Buyer questions

What to know before requesting a quote.

What information is needed for an initial quote?

Tell us the assessment type, approximate scope, business objective and preferred timeframe. Do not send credentials or sensitive system details through the form.

Can the scope be refined before testing?

Yes. Systems, access levels, permitted techniques, timing and reporting needs are agreed before testing begins.

Does a penetration test prove compliance?

No. Testing can provide technical evidence for a wider assurance programme, but it does not establish compliance or certification on its own.

Is retesting included?

Retesting is included only where it is agreed in the engagement scope.
