03 / 07Security Audit

We find the flaws before anyone else.

Our researchers attack your applications, APIs and infrastructure the way a real adversary would, then deliver a clear, prioritised report. Expertise recognised by the bug bounty programmes of the world's largest companies: over $105,000 in rewards earned in 2026.

What we do

Web penetration testing

Applications, back offices and portals tested against OWASP vulnerabilities and business logic flaws.

Mobile penetration testing

iOS and Android apps, local storage, communications and related APIs.

API audit

Authentication, access control, data leaks and logic abuse across your APIs.

Infrastructure audit

Networks, servers, cloud and external exposure: your attack surface mapped and reduced.

Code audit

Manual and tool-assisted source code review to catch vulnerabilities before they ship.

Red team

Realistic, sustained attack simulation to test how your teams detect and respond.
