Sine.co (Domain) Investigation Report
Generated on Jun 2, 2026
Why we think so?
🛡️ sine.co looks like a legitimate, established SaaS/property-management-style business rather than a scam. The site has a real Australian physical listing, working contact details, valid SSL, and a long trail of business infrastructure: Google Workspace mail, Cloudflare, AWS, HubSpot, Intercom, Stripe, PayPal, and more. Traffic is modest but real, with about 102.8K monthly visits and a strong Australian audience. I did not find blacklist hits, and public reputation signals are mostly neutral to positive, though there are some user complaints about billing and app stability.
