Not sure which test you need?
Most people searching “pen test” aren’t sure yet, that’s normal. Pick the closest match, or talk it through directly with a tester. We can incorporate multiple testing types for a single project. We often do web app + network testing if a business wants to cover both.

Our Values
What’s in your penetration testing report
The report is where a penetration test earns its value. A test is only as useful as the document that comes out of it, and ours are built to be read and acted on, not filed away. Every engagement ends with a clear, structured report that works for your technical team and your senior stakeholders alike.

When do you need a penetration test?
Penetration testing isn’t a one-off box to tick. It’s something to build into the key moments of your business. You should consider a test when:
- You’re launching a new product, application, or feature: test before it’s exposed to real users and real attackers, not after.
- You’re preparing for a compliance audit: ISO 27001, SOC 2, PCI DSS, Cyber Essentials Plus and similar frameworks expect independent testing as part of certification.
- A customer or partner is asking for it: enterprise procurement and due diligence increasingly require evidence of penetration testing before they’ll sign.
- You’ve made significant infrastructure or code changes: migrations, new integrations, or major releases can introduce vulnerabilities that weren’t there before.
- You’re going through a merger, acquisition, or investment: understand the security posture of what you’re buying, or reassure the people investing in you.
- You’ve had a security incident: verify that the gap is closed and check for anything else an attacker may have reached.
- It’s simply been a while: best practice is at least once a year. If you can’t remember your last test, you’re overdue.
Not sure which of these applies to you? A quick scoping conversation will tell you what you need, and just as importantly, what you don’t.
LIVE REPORTING
Stay informed throughout your penetration test with real-time access to findings through our secure client portal.
As vulnerabilities are identified, they’re immediately available for your team to review, giving you complete visibility into the assessment as it progresses. Any High or Critical findings are communicated straight away via your agreed contact channels, ensuring urgent risks are never left waiting until the final report.
Our collaborative approach also allows for interactive re-testing during the engagement. As fixes are implemented, our consultants can validate them in real time, helping to reduce outstanding vulnerabilities before testing is complete.
At the end of the engagement, your portal is updated with the final quality-assured report, providing a comprehensive record of the assessment, findings, remediation guidance, and supporting evidence.

Penetration testing FAQs
The cost depends on scope: the cloud platforms involved, the size and complexity of your environment, and the depth of testing required. Rather than quote a misleading flat rate, we scope every engagement individually so you only pay for testing that delivers real value. Get in touch for a tailored quote.
Not necessarily. We can test with no access (black box), partial access (grey box), or full access to source code (white box). Grey and white box testing often uncover more, and we’ll help you choose the right approach during scoping.
No. Wherever possible we test against a non-production environment such as UAT or QA, so there’s no risk to your live service. If that isn’t possible, we take a more cautious approach to post-exploitation testing to protect your users.
Yes. Our support doesn’t end at the report. Once you’ve addressed the findings, we can retest to confirm the fixes are effective, giving you and your stakeholders verified assurance that the risks have been closed.
The cost depends on scope: the platforms involved, the size and complexity of the app, the number of user roles and APIs, and the depth of testing required. Rather than quote a misleading flat rate, we scope every engagement individually so you only pay for testing that delivers real value. Get in touch for a tailored quote.
We start with a scoping conversation to understand your environment, objectives, and any constraints. Together we define exactly what’s being tested, the rules of engagement, and the timeline, ensuring the test aligns with your goals while minimising any risk of disruption.
