You might expect a site like financial.intelligence.informa.com to be a straightforward landing page for Informa's financial data products. But a closer look reveals something very different. The homepage returns a 404 error. There is no privacy policy, no terms of service, and no contact information anywhere. The domain ownership is completely hidden, which is unusual for any company name-branded subdomain, let alone one in the finance industry.
Legitimate financial intelligence or data services typically have clear legal pages, an about section explaining what they do, and some way for users to reach them. This site has none of that. It is hard to say whether it was abandoned, never fully set up, or something else entirely. What matters for you is that there is no reason to trust it with your data or your time. If you came here looking for financial reports or analytics, look for those through Informa's main website instead. There is no evidence that financial.intelligence.informa.com is a scam — the bigger issue is that there is no evidence it is a real business at all.
