This is a Microsoft SharePoint site, likely used by Duckhorn Vineyards for internal document sharing and collaboration. The site immediately redirects to Microsoft's official login page, which is exactly what you'd expect from a corporate SharePoint tenant. All security signals — from the valid SSL certificate to clean blacklist status — confirm this is a legitimate Microsoft-hosted service. There are no red flags like phishing or malware reports. The site doesn't have a public web presence or reviews because it's not meant to be publicly accessible; it's a private workspace behind authentication. If you've been sent a link to this site by a Duckhorn employee or partner, it's safe to use. Just make sure you're logging in through the Microsoft login page and not entering credentials anywhere else.

Where the score comes from
Solid security setup with modern encryption, HSTS, and clickjacking protection. No malware or phishing flags.
This is a subdomain of sharepoint.com (Microsoft), so the WHOIS not matching is expected. The identity is tied to Microsoft's domain registration, which is well-established.
Clean blacklists and no threats detected, but the site is not indexed by search engines or archived, which is normal for a private authenticated site.
This is an internal SharePoint site behind Microsoft login, so public contact info and about pages are not expected. The redirect to Microsoft's authentication is standard.
No legal pages visible, but as a private business tool not collecting public data, compliance requirements don't apply here.
Hosted on Microsoft's own network with clean DNS resolution and no email handling issues. DNSSEC not enabled is a minor gap but not a concern for this site type.
