If you've landed on portal.sso.eu-west-2.amazonaws.com, you're looking at an Amazon Web Services infrastructure URL, not a typical business website. The domain is owned by Amazon, so there's no mystery about who runs it. The security setup is clean — valid encryption, no blacklists, and no malware flags. That's all good.
But here's the practical issue: when you visit this URL, the server returns a 404 error with a JSON message saying the resource wasn't found. That means the AWS SSO portal you're trying to reach either doesn't exist or has been moved. This isn't a scam indicator — it's a configuration problem. If you were given this link by an employer or service, check that the full URL is correct, including any path after the domain. The domain itself is legitimate, but the specific page isn't working.
For anyone wondering "is portal.sso.eu-west-2.amazonaws.com a scam?", the answer is no. It's an official AWS endpoint. But it's also not a functioning website right now. Treat it as a broken link rather than a dangerous one.
