Questions

Pricing, answered.

Why are you cheaper than the big AI security firms?

Enterprise AI red teams are built for banks and large tech, with pricing to match — often £10,000 and up. We’re built for SMEs: the same offensive testing, scoped and priced for a business that doesn’t have an internal security team. Lower overhead, focused scope, no enterprise mark-up.

Why does the price depend on the system?

AI scope varies far more than a normal web app. A single chatbot on one model API is a very different job from a multi-tool agent with a live RAG pipeline. Price follows real complexity, not a flat rate, so you never pay for testing your system doesn’t need.

What’s included every time?

Full OWASP LLM Top 10 coverage, a plain-English executive report plus technical detail, a findings walkthrough call, and free retests of every fix until it’s confirmed closed. No cancellation fees, no per-retest charges.

How long does it take?

A Focused Review is usually 1–2 working days. A Full Red Team runs 5–8 days depending on complexity. The exact timeline is agreed at your consultation.

Do you need written permission to test?

Always. We never test a system without signed written authorisation, and everything is handled confidentially under NDA.

Do you retest after we fix things?

Yes, and it’s included. We retest every fixed finding until it’s confirmed closed. An assessment that only tells you what was broken is half the job.
