This URL isn't a typical business website but a technical subdomain, possibly part of Microsoft's Skype or Teams infrastructure. However, the SSL certificate is issued for a different domain, and the site returns a 404 error. Legitimate Microsoft services would have a valid certificate and be reachable. The lack of any public information or contact details means you cannot verify who controls this subdomain. While it's hosted on Microsoft's network, the certificate mismatch suggests either a serious misconfiguration or a potential impersonation attempt. Until it's resolved, treat it as unsafe. There are no reviews or history to consult, so caution is warranted.

20/ 100 trust score
In plain English

Where the score comes from
We look at six areas. Here's how callcontroller.swce-03.ic3-calling-callcontroller.swedencentral-prod.cosmic.office.net did in each.
15
Security
The SSL certificate is invalid because it was issued for a different domain, and the site is unreachable. This is a critical failure for any website that expects visitors to trust it.
30
Identity
The domain is a subdomain of office.net, but the specific subdomain is not registered in WHOIS, and there is no contact or ownership information. You cannot verify who controls this endpoint.
60
Reputation
No blacklists or Google Web Risk flags, but the site has no history in the Wayback Machine and is not ranked. It's too new or obscure to have a reputation.
40
Transparency
There is no about page, contact info, or social media presence. For a technical subdomain this is not unusual, but combined with the security issues it raises questions.
60
Compliance
No privacy policy or terms of service, which is normal for a non-commercial technical endpoint. No legal obligations apply here.
20
Infrastructure
The site is hosted on Microsoft's network but the SSL certificate is mismatched, the site returns a 404, and no security headers are set. This indicates a misconfiguration or a broken setup.
