The product

Klaxel

Live

Add your client domains once. Klaxel monitors every one, grades its health from A to F, and tells you the moment something slips — expiry, TLS, DNS, or deliverability. Built for the MSPs and agencies who run dozens or hundreds of domains across registrars.

  • 14 automated checks across 6 categories, graded A–F and re-checked daily
  • Proactive alerts the moment a domain slips — email, Slack, Microsoft Teams, or webhook
  • Escalating domain-expiry countdown at 60, 30, 14, 7, and 1 day out
  • White-label, per-client branded reports, a client portal, and ConnectWise PSA ticketing

What Klaxel monitors

Six categories, fourteen checks, one A–F grade per domain — run automatically, every day, so a quiet dashboard actually means everything is fine.

Certificates & TLS

Certificate validity and expiry, plus deep SSL/TLS posture — protocols, ciphers, and chain — so no site goes insecure on renewal day.

Email auth

SPF, DKIM, DMARC, and MX checked so client invoices and alerts land in the inbox, not the spam folder.

Web security

HTTPS enforcement, HSTS, redirect-chain integrity, and subdomain-takeover detection watched continuously.

Indexability

robots.txt and sitemap presence, plus noindex-leak detection — catch a client page silently set to noindex.

DNS

Nameservers and DNSSEC chain validation monitored across every registrar in a single view.

Reputation

IP and domain blacklist (DNSBL) checks flag a listing before it costs client deliverability or trust.
