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.

Priority findings

6 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

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.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

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.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

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.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

DSL holds a strong market position as a reputable cultural and educational institution supported by Danish government and private foundations. Its business model focuses on non-profit publishing and digital dissemination of linguistic resources. The organization leverages partnerships with various Danish linguistic projects and provides free online access to many resources, enhancing its reach and impact. The website's content and structure support its mission effectively, though it lacks visible commercial activities or monetization streams. Growth indicators include ongoing projects and recent awards for book craftsmanship.

Security posture

The website employs HTTPS with excellent SSL configuration and uses Cookiebot for consent management, indicating good privacy practices. However, it lacks DNSSEC, security headers like CSP or HSTS, and does not publish a security policy or incident response information. No vulnerability disclosure or security.txt files are present. The use of third-party scripts such as Google Tag Manager introduces moderate tracking but is managed with consent. Overall, the security posture is solid but could be improved by implementing DNSSEC, security headers, and transparency around security policies.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Implement security headers such as Content-Security-Policy, X-Frame-Options, and HSTS to harden the website against common attacks.
  3. Publish a clear security policy and incident response plan accessible from the website.
  4. Introduce a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  5. Regularly review and audit third-party scripts and tracking tools to minimize privacy risks and improve compliance.

Technical notes

Notes

The website is built on the Plone CMS platform, utilizing modern web technologies including jQuery, Slick Carousel, Google Fonts, and Google Maps API. It integrates Cookiebot for GDPR-compliant cookie consent and Google Tag Manager for analytics. The site is mobile-optimized with responsive design and good SEO practices including meta tags and Open Graph data. Performance is moderate, with potential improvements in loading speed. Accessibility is basic but present. The technical infrastructure is stable and well-maintained, though some modernization opportunities exist in security configurations and performance optimization.
Standards and sources

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.
