js.hscta.net is a subdomain that appears to be part of HubSpot's call-to-action tracking infrastructure. It returns a 403 Forbidden when visited directly, which is normal for a backend script endpoint. The site uses Cloudflare for fast delivery and has a valid SSL certificate, though it still accepts older TLS versions — a minor oversight. There's no public WHOIS record for this subdomain, and no about page or contact information, but for a tracking script host that's not unusual. The domain is not on any blacklists and has no malware flags.
When you see a subdomain like this, it's typically not something you interact with directly. The real question is whether the main service it belongs to (HubSpot) is trustworthy — and HubSpot is a well-known marketing platform. If you're checking because a website uses js.hscta.net scripts, there's no sign of foul play here. However, because we can't see behind the server's bot protection, we can't give it a perfect score. For most people, js.hscta.net is not something to worry about.
