- Covers everything Mail Check and Web Check did, and keeps checking every day
- Built in the EU and mapped to NIS2, DORA and eIDAS
- Open to any organisation, with nothing to install

Everything Mail Check and Web Check did, without the retirement date.
Point SkyQon at your domain and you get email authentication, TLS and DNS posture in a single scored report, re-checked daily.
Mail Check → Email-spoofing protection
SPF, DKIM, DMARC, MTA-STS and BIMI, checked continuously and graded into a plain-English Trust Score, with the exact record to fix when something is wrong.
Web Check → Web & certificate hygiene
TLS configuration, certificate expiry and chain health, DNSSEC and DNS security, plus discovery of subdomains you forgot you had.
Public-sector only → Open to any organisation
Mail Check and Web Check served the UK public sector only, and both are now retired. SkyQon is open to any organisation and starts free.
Why SkyQon is the right replacement
Made in the EU, for EU rules
Your data stays in the EU, and findings map to NIS2, DORA and eIDAS rather than a US compliance checklist.
Continuous, not a one-off
Mail Check and Web Check gave you a snapshot. SkyQon re-checks every day and alerts you when something changes: an expiring certificate, a broken DMARC record, a look-alike domain appearing in CT logs.
See everything, even on free
Every plan, including the free one, shows the complete diagnosis. Paid plans add the one-click fixes and audit-ready evidence on top.
Free covers up to 5 domains, continuously
Monitor up to 5 domains with a daily Trust Score across email, DNS, certificates and TLS, with email alerts included. Free forever, no card. When you need exact fixes, faster checks or compliance evidence, upgrading takes a click.
Turn the checks into NIS2 and DORA evidence
If NIS2 or DORA applies to you, SkyQon turns the same monitoring into signed, verifiable technical-evidence reports: the paper trail auditors ask for, without a consulting engagement.
