Threatconnect.com has been around since 2011, which normally signals a legitimate business. The technical foundation is solid: valid encryption, strong email authentication, and no history of malware or blacklisting. On paper, it looks fine.
But there's a problem. The site doesn't actually show you anything from threatconnect.com. Visit the homepage and you land on dataminr.com instead, with no branding or transition. It's not clear whether threatconnect was acquired, rebranded, or simply parked. Either way, there's no visible ownership, no privacy policy, and no contact information tied to this domain.
For a security company that may have handled sensitive threat intelligence data, that lack of transparency matters. If you were a former customer of threatconnect trying to access your account or verify what happened, you'd be stuck. There's no evidence of a scam here, but there's also not enough clarity to recommend trusting the domain with personal information today. Before you enter any data or assume this is the same service you used years ago, it's worth doing some extra digging to confirm who's behind the current site.
