Know your domain is healthy,
before your customers notice.
ZoneVitals checks DNS, SSL, SPF/DKIM/DMARC, blacklists and uptime around the clock, and alerts you the moment something breaks.
Everything that keeps your domain alive
One dashboard for the stuff that silently breaks.
DNS health
MX, DNSSEC and record changes tracked daily, with alerts on any unexpected diff.
SSL certificates
Expiry, chain validity and hostname match, with warnings well before a cert lapses.
Email authentication
SPF (including the 10-lookup limit), DKIM selectors and DMARC policy checks.
Blacklist monitoring
Your mail servers checked against major DNS blocklists so deliverability doesn't tank.
Uptime monitoring
HTTP and TCP checks down to every minute, confirmed failures, incidents and uptime %.
Public status pages
Share a clean status page with customers, behind an unguessable link.

FAQ
Is the free scan really free?
Yes. Scan any domain without an account. Sign up to have it checked automatically with alerts.
What do you need access to?
Nothing. All checks use public DNS, TLS and HTTP, so there's no agent to install and no credentials to share.
How are uptime failures confirmed?
A monitor is marked down only after consecutive failed checks, so you aren't woken up by a single blip.
Can I cancel anytime?
Yes. Plans are month-to-month and you can downgrade to Free whenever you like.
