When you run into a URL like chiesi-my.sharepoint.com, it's natural to wonder if it's safe. This particular site is a Microsoft SharePoint subdomain, set up for Chiesi, a pharmaceutical company, as a private collaboration space. Instead of showing a public homepage, it immediately redirects to a Microsoft login page — that's standard behavior for corporate SharePoint portals. You can't browse the site without signing in with a work account, which limits access to authorized users only.
The technical signals back this up. The site uses strong encryption, forces a secure connection, and has protections against common web attacks. It's hosted on Microsoft's own network and isn't found on any blacklists. The lack of a web archive history or public contact page isn't a red flag here — internal tools aren't meant to be archived or listed.
If you're asking "is chiesi-my.sharepoint.com safe?" the answer is yes, as long as you have a legitimate reason to access it. This is not a public store or a service you sign up for randomly. If someone sent you this link and you don't have a Chiesi work account, you won't be able to get in — and that's by design.
