Find the certs & subdomains you forgot about
Enter your domain. We map every SSL certificate and subdomain from Certificate Transparency + DNS, and flag expiring certs and subdomain-takeover risk.
One-time scan. We don't store your domain. Certificate Transparency logs are public.
Certificate Transparency
Every cert ever issued for your domain — including subdomains you forgot existed.
Live SSL expiry
Real handshakes catch certs that expire in the next 14 days, before your users do.
Takeover risk
Dangling DNS pointing at unclaimed Vercel/S3/Heroku — a real hijack vector.
