Frequently Asked Questions
Here is a list of commonly asked questions from clients
How much does a penetration test cost?
The cost of a penetration test in the UK typically ranges from £3,000 to £15,000, depending on scope, complexity, and whether the environment is internal, external, web-based, cloud-hosted, or mobile. Pricing is scoped using daily-rate. (commonly £1,200-£1400/day)
What kind of penetration testing service do I need?
That depends on your assets, risks, and compliance requirements. For example, a SaaS company will likely need web application and API testing, while a finance firm may need internal network and Active Directory tests. Cloud-based companies may benefit from AWS/Azure security reviews, while mobile-first companies often need iOS/Android app testing. A quick discovery session can map your infrastructure to the most relevant testing types.
Will this help us meet compliance (e.g., ISO 27001, Cyber Essentials Plus, PCI-DSS)?
Yes, penetration testing is often a requirement or strong recommendation under many standards like ISO 27001 (A.12.6.1), Cyber Essentials Plus (for external testing), PCI-DSS (Requirement 11), and others. We tailor the methodology and reporting format to align with these frameworks so you can use the results directly in audits or board reports.
How long does a penetration test take?
A typical engagement lasts 3 to 10 working days, depending on the scope and depth required. Small external scans can take a few days, while complex environments involving multiple applications, APIs, or networks may take 2–3 weeks. We’ll provide a detailed timeline during scoping so you can plan accordingly.
Will the test disrupt our systems or affect users?
Penetration tests are designed to be non-disruptive, but there’s always a minor risk during certain types of testing, such as brute force or denial-of-service attempts. We avoid these by default unless explicitly authorised. All tests are scheduled and coordinated to minimise business impact, and we never test live systems aggressively without written consent.
What do we get at the end of the test? (i.e., what does the report include?)
You’ll receive a comprehensive report that includes an executive summary, risk-ranked findings (e.g., Critical, High, Medium), technical details, real-world impact explanations, and clear, actionable remediation guidance. We also offer a walkthrough session to discuss findings, answer questions, and support remediation efforts if needed.
How often should we do penetration testing?
As a general rule, testing should be done at least annually, after any major code changes or deployments, or when there are significant changes to infrastructure. Some clients test quarterly or continuously as part of DevSecOps pipelines, especially in regulated industries or fast-moving tech environments.
Who performs the test and are they qualified/CREST/CHECK certified?
Our testers are experienced professionals, often with CREST, OSCP, or CHECK certifications, and many hold SC clearance if required for sensitive sectors. Each consultant brings deep technical knowledge, real-world attack experience, and familiarity with UK compliance frameworks, ensuring both rigour and relevance.
What happens if you find something critical?
If a high or critical risk is discovered during testing, we follow a responsible disclosure process: you’ll be notified immediately, with suggested mitigations, and we pause further testing if necessary. Our goal is to help you contain and remediate the issue swiftly, and we’ll support you until resolution, including retesting if needed.
