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

2 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. 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

The company positions itself as a specialized software development and IT consulting firm with a focus on tailored solutions rather than off-the-shelf products. Their business model includes product development (notably easyVerein and other platforms), consulting, and digital marketing services. The target market spans startups, SMEs, mid-sized companies, public institutions, and associations, indicating a broad but focused customer base. Their certifications and memberships in recognized industry bodies enhance their competitive advantage and trustworthiness. The company emphasizes long-term partnerships and comprehensive client support, which suggests a service-oriented growth strategy. Their regional base in Freiburg is complemented by a broader German-speaking market reach, supported by digital and cloud technologies enabling remote collaboration.

Security posture

The website demonstrates a strong security posture with enforced HTTPS, presence of multiple security headers, and a GDPR-compliant cookie consent mechanism. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of a public vulnerability disclosure policy or security.txt file and lack of explicit incident response contact details represent areas for improvement. The company shows awareness of data protection and IT security through dedicated consulting services and certifications such as the Allianz für Cyber-Sicherheit. Overall, the security maturity is high but could be enhanced by formalizing vulnerability and incident response disclosures.

Recommendations

  1. Publish a public vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  2. Provide explicit incident response contact information, such as a dedicated security or abuse email address.
  3. Consider publishing data protection officer contact details if applicable to enhance GDPR transparency.
  4. Maintain and update security headers and SSL configurations regularly to sustain high security standards.
  5. Enhance analytics transparency by disclosing data retention policies and user tracking details.

Technical notes

Notes

The website is built using modern web standards including HTML5, CSS3, Bootstrap 5, and FontAwesome icons, ensuring responsive and accessible design. Performance appears optimized with compressed images and efficient layout. No CMS was detected, indicating a custom or static site approach. The site includes interactive elements such as carousels and lightbox galleries, enhancing user experience. SEO is supported by comprehensive meta tags, Open Graph, and Twitter card metadata. Accessibility considerations are evident but could be further improved with ARIA roles and landmarks. Hosting provider details are not explicit, but domain and DNS data suggest stable infrastructure. Overall, the technical implementation supports a professional and scalable web presence.
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.
