Who's accountable for the outputs?
Specification-led security testing for APIs and AI systems. We find the flaws that scanners are structurally unable to find.
AI System Testing
Poor products are rarely the result of bad code or poor testing. Rather they result from specification not being written precisely enough. If nobody defined what the system should do in a given case, that simply gets missed. Most defects, most security breaches, and most AI failures trace back to this, not to mistakes in code.
The API layers of digital applications are often a huge attack vector, but these load-bearing structures can be the least scrutinised area. Business logic flaws don't show up in automated vulnerability scans. An API must be deeply understood before we can creatively discover where the genuine vulnerabilities are.
Who is taking responsibility for the quality of the outputs from your AI application? Inputs are not limited to chatbot interfaces and direct prompting. Are you defining what good looks like and how much variance is acceptable in your system's outputs? Are you checking this at scale?
What we do
Built for mid-market teams in fintech, insurance, gaming and energy: big enough that an API breach or AI failure is existential, without an army of in-house specialists.
01 · API Security
Business logic and API security. OWASP API Top 10, authentication, authorisation, and the flaws scanners are structurally unable to find.
API & Web Security →02 · AI System Testing
Empirical failure rates for AI systems before deployment. Quantified, characterised, against your criteria. Not the vendor's benchmark. Yours.
AI System Testing →03 · Test Engineering
Playwright, K6 and BDD suites delivered into your repo and CI. Specification made executable.
Test Engineering →04 · Philosophy
The discipline of finding what was never specified. Why specification gaps are where bugs, breaches and AI failures live.
Read the philosophy →Who
Testclub was founded in 2012 by Omar El Dali, built on twenty-five years at the boundary between specification and implementation, across trading platforms, fintech, insurance, health, energy and government.
A skilled high-agency group who move fast and adapt to what your project actually needs. Every finding arrives with its evidence and the method that produced it, so an engineer can follow every step.
