About Tehnoguru
Tehnoguru helps teams review spoofing exposure, email authentication, delivery posture, and look-alike risk for business domains.
What the service does
Add recurring checks, alerts, and reporting when the domain needs ongoing oversight.
Results are readable for non-technical stakeholders, with technical depth available when needed.
What the checker covers
The checker brings SPF, DKIM, DMARC, MX, MTA-STS, TLS-RPT, scoring, recommendations, and similar-domain findings into one view.
- Optional live delivery test when message-path verification matters
- Plain-language summary first, technical detail when needed
- Look-alike findings shown alongside the main domain result
How monitoring works
Managed monitoring is activated during onboarding. After setup, approved users receive recurring reports, alerts for meaningful changes, look-alike monitoring, and portal access.
Who it is for
Tehnoguru is built for business domain owners, IT administrators, security or operations teams, and service providers responsible for real mail domains.
