Why teams choose CertaDNS
Works with your existing DNS
Turn on email auth or brand monitoring without re-delegating your domain. Keep Cloudflare, Route 53, your registrar — whatever you use.
Transparent, per-domain pricing
Pay for the domains you protect. No “contact sales,” no five-figure floors, no surprise overages.
Redundant by design
Six authoritative servers on two independent networks, across five locations on two continents, all DNSSEC-signed. A regional outage cannot take the whole fleet.
From one host to a whole team
A free hostname for your home lab or organization-wide email security with roles and SLAs — same account.
Enterprise email security, without the enterprise invoice
