Have you joined RAG? its the fastest growing forum for fraud and revenue assurance across telecoms, banking and industry, https://riskandassurancegroup.org/
I'm at the second day here in London and the focus is on fraud process withing a company, Mark Broom,Director risk at Orange is sharing some great content. Next meeting will be in Kenya.
The message I'm hearing is that mobile phone operators and the wider business community are coming together with increasing speed meaning that we all need to be working together to fight fraud and protect our assets.
I recommend that you consider joining, its free so are the conferences and its growing around the world.
