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. Security headers

    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.

    • High

      Missing Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1

  2. GDPR outside view

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

    • 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 Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, LinkedIn, Google APIs

      What to do: Document all third-party data sharing in your privacy policy

  3. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

High DC positions itself as a regional ecological data center provider with a niche focus on local cloud services and dedicated fiber connectivity. Its competitive advantage lies in its altitude-based free cooling system and partnerships with established local operators. The business model targets SMEs and enterprises in the canton of Neuchâtel seeking secure and local data hosting. The company maintains a small size but demonstrates growth potential through strategic partnerships and certifications. The website content and partner logos reinforce credibility and market presence, though expansion of compliance documentation could enhance trust further.

Security posture

The website demonstrates a mature security posture with HTTPS, reCAPTCHA on forms, and ISO 27001 certification. However, the absence of explicit security headers such as Content Security Policy and HSTS reduces defense-in-depth. No incident response or vulnerability disclosure information is publicly available, which could hinder transparency. The cookie consent mechanism aligns with GDPR, but a dedicated privacy policy page is missing. Overall, the security measures are solid for a small data center operator but could be improved by publishing more comprehensive security and privacy documentation.

Recommendations

  1. Publish a comprehensive privacy policy page to improve GDPR compliance and user trust.
  2. Implement and publish security headers like CSP, HSTS, and X-Frame-Options to enhance security posture.
  3. Create and disclose an incident response policy and vulnerability disclosure program to increase transparency.
  4. Enhance accessibility features to improve usability for all users.
  5. Regularly audit third-party scripts and plugins to ensure no vulnerable libraries are in use.

Notes

The website uses a WordPress CMS with the Salient theme and WPBakery page builder, integrating modern JavaScript libraries such as jQuery and Google Analytics for tracking. Performance is moderate, with caching via WP Rocket and preconnect optimizations. The site is mobile responsive and SEO optimized with Yoast SEO. Error monitoring is enabled via Sentry. No hosting provider details were detected. The technical stack is standard for small to medium business websites, with opportunities to improve performance and security through additional header configurations and privacy documentation.
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.
