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

7 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 Cookie Policy found

      GDPR requires clear information about cookie usage

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

  2. 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
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

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

The company operates in the technology sector, focusing on semantic wiki solutions for management systems. Their business model revolves around software development and deployment for enterprise and institutional clients, emphasizing smart management and automation of information workflows. The presence of customer testimonials and detailed product descriptions suggests a customer-centric approach and established market presence. The company targets medium to large organizations requiring structured quality and project management solutions. Their digital footprint includes active social media profiles on Twitter, LinkedIn, Xing, and GitHub, indicating engagement with professional and developer communities. The firm has been operational since 2010, reflecting stability and experience in their niche. No parent or subsidiary companies were identified, suggesting an independent small-sized enterprise.

Security posture

The website demonstrates a basic to moderate security posture. HTTPS is enforced, ensuring encrypted communication. However, the absence of DNSSEC and security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security reduces defense-in-depth. No explicit security or incident response policies are published, which could hinder transparency and preparedness in case of security incidents. The site uses CSRF tokens in forms, indicating awareness of common web vulnerabilities. No vulnerabilities or exposed sensitive data were detected in the HTML content. The use of Matomo analytics suggests a preference for privacy-respecting tracking. Overall, while foundational security measures are in place, enhancements are recommended to align with best practices and compliance requirements.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Implement standard security headers including Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, and Strict-Transport-Security.
  3. Publish a clear security policy and incident response contact information on the website.
  4. Create and maintain a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  5. Regularly audit and update third-party libraries and dependencies to mitigate potential vulnerabilities.

Technical notes

Notes

The website is powered by MediaWiki 1.31.6 with Semantic MediaWiki extensions, indicating a robust content management and semantic data platform. The front-end uses Bootstrap for responsive design and jQuery for client-side scripting. FontAwesome provides iconography. Matomo analytics is integrated for user tracking with a focus on privacy. The site loads scripts asynchronously and defers non-critical resources, contributing to moderate performance. Mobile optimization is good, with responsive images and layout. SEO is supported by comprehensive meta tags, Open Graph, and JSON-LD structured data. Accessibility is basic but present. Hosting details are not explicit, and no CDN or cloud provider is identified. The domain lacks DNSSEC, which is a technical risk. Overall, the technical infrastructure is solid but could benefit from modern security enhancements and performance tuning.
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.
