Full populations tested where it matters. Every decision clearer.
Helping organisations see around the corner.
RAiN combines more than 20 years of audit and advisory experience with Monsoon, an AI-native platform developed by PEAQ, RAiN's technology division. AI supports our sample-based testing, and where you need it, we test the full population. Either way, our people spend their time on what matters to you.
Sample or every transaction. Now you can choose.
Sampling is still the right tool for many audits, and AI makes our samples sharper. But with thousands of transactions, suppliers and sites, some risks hide between the items a sample picks. Where that matters, we can now test everything.

- Every transaction is a raindrop. This illustration: 12,480 invoices.
- A sample tests a selection. An unusual invoice can fall outside it.
- Test the full population, and every invoice that matches the test criteria is flagged for an auditor to review.

Intelligent. Accountable. Secure.
The Monsoon platform is certified to ISO 27001:2022 for information security and ISO 42001 for AI management (held by PEAQ; certified by AENOR, 2026), and a penetration test of the platform was completed successfully in 2026. Your data is handled in line with POPIA, as set out in our PAIA and POPIA manual, and AI agents' outputs are reviewed by qualified RAiN professionals at agreed review points — technology does the checking, people make the judgements.

Technology assets
Technology that makes our work deeper, more accurate and secure.
Our teams work with Monsoon, a platform developed by PEAQ, RAiN's technology division, and certified to ISO 27001 and ISO 42001. What it means for your engagement:
- AI in both sample-based and full-population testing, on defined procedures
- Sample or full population, you choose: testing every transaction takes more work, so it costs more than a sample, but far less than doing it by hand source: a cost comparison or example to support "far less than by hand"
- Every flagged figure traced to its source document
- AI used under certified information-security and AI-management controls
- Our people's time spent on judgement and advice
