Rimscan monitors your company's external attack surface and shows what attackers see first: exposed subdomains, takeover risks, DNS/SSL misconfigurations, and leaked secrets. Built by a working security researcher, for teams that want ongoing visibility without manual recon or quarterly pentests. Free: 1 domain, 5 scans every 14 days. Pro ($29/mo): 10 domains, automatic scans every 2 days, 5 Deep Scans per month. Start free, no credit card required.

We built RimScan because keeping track of an external attack surface shouldn't require stitching together five different tools and manually re-checking them every week. RimScan continuously monitors your company's domains — subdomain enumeration, takeover detection, DNS/SSL auditing, and exposed secrets scanning — and alerts you the moment something changes. No manual recon, no quarterly pentest gaps. We're still early and actively shipping. We'd love your feedback — what's missing, what feels off, what you'd want next. There's a feedback option built right into the dashboard for exactly that. Free tier is fully usable, no card required — try it on a domain you own and let us know what you think.
