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 Cookie Policy found

      GDPR requires clear information about cookie usage

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

    • 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

  2. Security headers

    • 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

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 business operates in the technology and media sectors, organizing conferences and digital events that foster networking and knowledge sharing among professionals involved in digital transformation. The platform leverages the strong brand of heise medien to maintain market position and credibility. Revenue likely derives from ticket sales, sponsorships, and partnerships. The target audience includes corporate decision-makers and tech professionals. The partnership with betaITS for online meetups indicates an ecosystem approach. The business model is event-centric with digital content extensions, supporting growth and community building.

Security posture

The website demonstrates a mature security posture with HTTPS enabled and no exposed sensitive data. The use of Matomo analytics suggests a privacy-aware approach. However, the absence of explicit security headers (like CSP, HSTS) and lack of published security or incident response policies represent areas for improvement. No vulnerability disclosure or security.txt files were found, which could enhance transparency and trust. Overall, the security risks are low but can be mitigated further by adopting best practices and compliance measures.

Recommendations

  1. Implement a visible cookie consent banner to comply with GDPR and improve privacy transparency.
  2. Add security headers such as Content-Security-Policy, Strict-Transport-Security, and X-Frame-Options to enhance protection.
  3. Publish a security policy and incident response contact information to improve trust and preparedness.
  4. Consider adding a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  5. Regularly audit third-party scripts and libraries to ensure no vulnerabilities are introduced.

Technical notes

Notes

The website uses a modern front-end stack with HTML5, CSS3, and JavaScript libraries including Swiper for sliders, Fancybox for modals, and GSAP for animations. Matomo is used for analytics, indicating a preference for privacy-friendly tools. Hosting is via Schlund Technologies, consistent with the domain's nameservers. The site is mobile-optimized with responsive design and good navigation clarity. Performance is moderate, with potential for optimization. Accessibility is basic but could be improved. SEO is well addressed with proper meta tags and Open Graph data. No CMS is explicitly detected, suggesting a custom or static site approach.
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.
