If you came across eu2-wms2.zoho.eu and wondered whether it's safe, here's the short answer: it's a technical server, not a website you interact with directly. The domain is a subdomain of Zoho, a respected business software company. The server is used for persistent connections related to Zoho's warehouse management system, hosted on Amazon Web Services.
For a server of this kind, the signals that matter most are security and ownership. The SSL certificate is valid and uses modern encryption. The hosting is on Zoho's own network, which is a good sign. Missing privacy policies or contact pages are completely normal — this isn't a store or a service you log into. The lack of a sitemap or robots.txt is also typical for internal endpoints.
So is eu2-wms2.zoho.eu a scam? No — the evidence points to it being a legitimate component of Zoho's infrastructure. There's no risk in connecting to it. If you're evaluating Zoho's services as a whole, this server shouldn't raise any flags.
