How privacy works
Private lookups are not added to public searches, stored reports or change history. This does not remove a report that was already public. Your choice lasts for this browser session.

What needs attention
Prioritized observations from this check. Review changes with whoever manages the website.
- Improve
DMARC is in monitoring mode
The published p=none policy does not request rejection or quarantine of failing messages.
Next step: Review DMARC reports and SPF/DKIM alignment before considering a stricter policy.
- Improve
Review browser security headers
Content-Security-Policy, Referrer-Policy, Permissions-Policy did not meet the conservative header checks. This is not a complete security audit.
Next step: Review these headers with the site developer and test policy changes before enforcing them.
- Good to know
Only the network operator is identified
The visible IP network is known, but no hosting-specific evidence confirms the company or reseller serving the site.
Next step: Use the evidence as a network attribution and verify the hosting provider with the website owner if needed.
Evidence by layer
The company operating a network and the company selling the hosting can be different.
Network operators
M5HOSTING - M5 Computer Security, US
