Port Discovery
Find a port that's open now but wasn't before.
Port discovery scans a host you own across the full TCP range and reports any port that has newly opened — an exposed database, admin panel or debug port. Only scan infrastructure you own or are authorized to test.
What it detects
- Newly opened ports, by number
- Ports outside the list you expect to be open
How you're alerted
- “New Open Port Detected” fires on its own when a port newly opens.
Notifications go to any of 8 channels — see notifications.

- Interval

Certificate expiry alerts before anything breaks.
WHOIS Monitoring
Track a domain's own registration expiry and catch an unexpected ownership transfer — independent of its SSL certificate.
Certificate Transparency Log Monitoring
Get notified the moment a new certificate is issued for your domain or a subdomain — catches unauthorized issuance and shadow IT early.
Subdomain Monitoring
Find your domain's subdomains in Certificate Transparency logs and get alerted on new ones and on dangling CNAMEs that could be taken over.
Typosquatting Monitoring
Find registered lookalikes of your domain — typos, homoglyphs, IDN homographs, other TLDs, "brand-login" names — and get alerted when a new one appears.
DNS Blacklist Monitoring
Check whether an IP (or a hostname's IP) is listed on spam blacklists — catch a reputation problem before it blocks your mail.
Email Authentication
Watch a domain's SPF, DKIM and DMARC records for the silent misconfiguration that tanks deliverability.
Cookie Monitoring
Track a page's cookies for unexpected additions, removals, or security-attribute changes — Secure, HttpOnly, and SameSite, not just whether a cookie is still there.
