If you came across 193814-ipv4.farm.dprodmgd105.aa-rt.sharepoint.com.dual-spov-0006.spov-msedge.net, you might wonder if it's safe. The short answer is that it's not really a website at all. This address is a deeply nested subdomain of Microsoft's sharepoint.com, likely a CDN edge node that's either misconfigured or temporarily offline. The SSL certificate is issued for a different hostname, so any browser will block the connection. The page returns a 400 error and a message that services aren't available. There's no business, no contact information, and no privacy policy because there's nothing to buy or sign up for. For a technical infrastructure node, all of this is unremarkable. But if you were expecting a functional site, you found a dead end. There's no evidence of malicious intent, but also nothing to trust. Treat it as a broken link and move on.
