WHOIS Monitoring
Domain registration expiry and ownership changes — invisible to an SSL check.
A WHOIS monitor watches when your domain's registration expires and who owns it. A domain can keep resolving while it has quietly been transferred — this catches that.

What it detects
- A registration within the days you choose of expiring (30 by default)
- A change in registrant name, organization or email
How you're alerted
- “WHOIS Registrant Changed” fires on its own when ownership changes — no rule to write.
Notifications go to any of 8 channels — see notifications.
- Runs from
- MonSPHERE's own workers — no region to pick
- First check
- Records a baseline — nothing is flagged until something changes
- Interval
- At most every 6 hours (registrars rate-limit lookups)
- Available on
- Free, Professional · Enterprise and Custom on request

Certificate expiry alerts before anything breaks.
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.
Port Discovery
Full-range TCP port scan of a host you own to flag any port that's open now but wasn't before — an early warning for an accidentally-exposed service.
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.
Third-Party Script Integrity
Get alerted when a third-party script your page loads changes — an early warning for supply-chain and card-skimming attacks.
