Detect new competitor subdomains before launch day.
Every new subdomain needs an SSL certificate, and every certificate is logged publicly the moment it's issued - before the site goes live. IntelCue watches Certificate Transparency feeds in real time, so a competitor's new subdomains reach you as early signals of what they are about to launch.

The earliest signal in competitive intelligence
Every HTTPS website requires an SSL certificate. Every certificate is recorded in public Certificate Transparency logs the moment it's issued - often days or weeks before the site goes live publicly. This makes CT logs the earliest available source of intelligence about competitor infrastructure changes.
When a competitor registers checkout.competitor.com, that subdomain appears in CT logs before a single user visits it. When they stand up enterprise.competitor.com, you see it in CT feeds before the product is announced. IntelCue watches CT logs continuously and surfaces these signals the moment they appear.
This isn't theoretical. Competitive teams who monitor CT logs routinely discover competitor product launches, new market entries, white-label partner programs, and new geographic expansions - all before press releases are issued or marketing campaigns go live.
How it works
Add competitor domains to track
Enter the root domains of the competitors you want to monitor. IntelCue immediately begins watching CT log feeds for every certificate issued under those roots.
CT feeds are monitored in real time
IntelCue continuously ingests Certificate Transparency feeds from major certificate authorities. New certificates typically appear in your feed within minutes of issuance.
Get alerted on new subdomains
Each new certificate triggers an alert in your intelligence feed, showing the full subdomain, issuing CA, and timestamp. IntelCue's AI adds context - flagging patterns that suggest product launches, new markets, or brand protection issues.
New certificate issued for beta.rival-corp.io - looks like a staging environment for an upcoming launch.
