When you visit collercapital.interactgo.com, you're immediately sent to login.microsoftonline.com with a SAML request for Coller Capital. That's a common pattern for corporate single sign-on portals. But here's the problem: the subdomain itself has no identifiable owner and no contact information. A legitimate company's SSO redirect would typically be set up on a domain they control, not a generic subdomain of interactgo.com with hidden WHOIS records.
For a login page, you need to be sure you're landing on the real portal. In this case, the destination (Microsoft's Azure AD login) is trustworthy, but the middleman domain offers no proof it was authorized by Coller Capital. A scammer could easily create a similar redirect to steal credentials by sending you to a fake Microsoft login page — though the SSL certificate and clean reputation don't indicate that here.
So is collercapital.interactgo.com a scam? There isn't enough evidence to say yes, but there's also too much opacity to say no. If you're a Coller Capital employee or client, verify the correct SSO URL with your IT department before entering any credentials. For everyone else, treat this as an unverified redirect and proceed with caution.
