Email authentication monitoring

Stop guessing whether your email is spoofable.

Continuous SPF, DKIM, DMARC, MTA-STS and TLS-RPT checks for every domain — including parked ones attackers love — with exact records to fix each issue.

Included on every plan

Everything that expires, in one place.

Email authentication

SPF (including the 10-lookup limit), DKIM, DMARC, MTA-STS and TLS-RPT — checked continuously, with plain-English fixes.

Domain registrations

Registry expiry, registrar, transfer lock and nameserver changes for every domain you own. A surprise nameserver change gets a high-priority alert.

Every TLS certificate

We pull every cert ever issued for your domains from public Certificate Transparency logs, then handshake each live endpoint — including VPNs, mail servers and odd ports nobody remembers.

New subdomains + takeovers

New hostnames show up in CT logs the moment someone issues a cert. We flag them, and catch CNAMEs pointing at deleted cloud resources before someone else claims them.

Exposed services

Weekly checks for RDP, SMB, databases and other ports that should never face the internet — on domains you've verified you own.

Microsoft Entra secrets + SAML

Read-only Graph access lists every app-registration secret, certificate and SAML signing cert, so SSO and integrations don't die on a Tuesday.

FAQ

Do you process DMARC aggregate reports?

Not yet — we monitor your published DNS posture and changes to it. Report processing is on the roadmap.

Do you need access to our servers or network?

No. Everything is outside-in: public Certificate Transparency logs, DNS, the registry, and the same TLS handshake a browser makes. The optional Microsoft add-on is read-only (Application.Read.All) and you can revoke it any time.

Why verify the domain?

So we only actively test infrastructure you own. Until you verify, we limit ourselves to passive data plus your main website. Verification is a single TXT record — or a file on your web server.

We already use ACME / Let's Encrypt. Do we need this?

ACME handles the easy certs. The outages come from the ones it doesn't: appliances, VPNs, load balancers, vendor-hosted subdomains, SAML certs, app secrets, and the domain itself. We also catch ACME jobs that silently stopped renewing.

How is this different from an EASM platform?

We focus on the expiry and misconfiguration problems that cause real outages, at a fraction of enterprise pricing, with setup in minutes rather than a sales cycle.
