Our Approach
Delivering The Best Possible Results For Our Clients
Our approach has been developed over 25 years in business and led us to develop long-term working relationships with organisations across the world. From global tech companies, with large, complex test requirements through to small companies requiring a single annual test.
1. Understand Your Requiremets
Before a single test begins, our dedicated Account Managers take the time to understand your organisation, your environment, your objectives, your risk appetite, and what a successful engagement actually looks like for you. Only then do we put forward a bespoke proposal.
2. Expert-Led, Manual Testing
Our testing is led by directly employed, highly certified consultants who are chosen for their technical depth and their ability to find what others miss. We don't subcontract. We don't rely on automated scanning in place of human judgement. Every engagement is carried out by the calibre of consultant we'd want testing our own systems.
3. Reporting, Tailored to your Organisation
A report is only useful if the right people can act on it. That's why our reporting process is built around your needs, whether that means in-test notifications, integration with your ticketing systems, a bespoke report format, or a full findings walkthrough with your technical team. We adapt to how you work, not the other way around.
4. Post-Test Support
Our consultants remain available after every engagement to help you interpret findings, prioritise remediation, and answer questions as they arise. Fix checks are available to verify that issues have been successfully resolved, and additional documentation can be provided for audit or compliance purposes.
