Scanned
NIS2 Art. 21(2)
This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.
GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.
No critical or high findings. These medium findings are worth fixing next.
Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.
Controls browser features and APIs
What to do: Implement a Permissions-Policy to restrict feature access
These are the privacy signals visitors and data protection authorities look for under GDPR.
Privacy policy lacks explicit GDPR compliance elements
What to do: Update privacy policy to explicitly address GDPR requirements and user rights
SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.
MTA-STS enforces TLS for email delivery
What to do: Implement MTA-STS to prevent downgrade attacks
DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.
DNSSEC is not configured for this domain
What to do: Enable DNSSEC to prevent DNS spoofing attacks

Each check with its score, findings and the evidence it collected.
The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.
Partial scans
When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.
Automated reading of the public site. Ratings are indicative.
Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
