As technical security specialists we research and identify exploitation vectors across applications, networks, and infrastructure - then apply this knowledge to your systems.
Comprehensive security testing using real-world exploit techniques, aligned to industry standards including PCI-DSS mandated testing requirements.
Uplift security culture across your entire organisation - from developer-focused CTF events and code review challenges to awareness programmes for non-technical staff.
Full technical reports, business summaries, or issue-tracker tickets - structured around root cause analysis and common-denominator remediation to prevent recurrence.
Collaborative scoping to understand your architecture, concerns and future development plans - tailored testing that is calibrated to your organisation's attack surface.
Are your assumptions appropriate in the face of growing AI threats? Is your organisation prepared to defend itself against the increasing number of attack events? Are your AI driven code bases exposing you to risks?
It is easy to get lost in the sea of AI generated code, legacy systems and new features about to go-live. We have tailored techniques to help assess the lay of the land and provide guidance in choosing focus areas to achieve effective outcomes.
In a world with an overwhelming number of alerts, security findings and questions, it can be difficult to work out priorities. We verify real threats, not hallucinated or theoretical findings and help you assess what is most important right now.
How we work
We discuss your project background, previous security measures taken, and future development plans to define precise engagement boundaries.
Expert penetration testers use current exploits and industry research against your deployed technologies, building on industry standards.
Root-cause analysis and remediation guidance delivered in your preferred format - from full technical reports to issue-tracker tickets.
We present and discuss findings with both management and technical teams, and support remediation efforts through targeted retesting.
