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

  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 dfv Mediengruppe holds a strong market position as one of Europe's largest independent business media companies, with a diversified business model encompassing specialist publications, digital offerings, and events. Its extensive sector coverage includes industries such as hospitality, finance, agriculture, and technology. The company leverages partnerships with major service providers for email and analytics, ensuring robust operational capabilities. The target audience comprises industry professionals and decision-makers, supported by a high-quality content portfolio and active engagement through social media and events. The business demonstrates growth potential through digital transformation and international expansion, particularly in German-speaking and European markets.

Security posture

The website exhibits a good security posture with valid SSL certificates supporting modern TLS protocols and no known critical vulnerabilities. Email security is enforced through a comprehensive SPF record and a strict DMARC policy set to reject unauthorized emails, reducing phishing risks. However, the absence of HSTS and OCSP stapling indicates areas for enhancement in transport security. No explicit security or incident response policies are publicly available, which may impact transparency and readiness. The use of a consent management platform aligns with GDPR compliance, but further disclosure of data retention and incident response procedures would strengthen the security framework.

Recommendations

  1. Enable HTTP Strict Transport Security (HSTS) with includeSubDomains and preload to enforce HTTPS usage.
  2. Implement OCSP stapling to improve SSL certificate revocation checking and reduce latency.
  3. Deploy DNSSEC to enhance DNS integrity and prevent spoofing attacks.
  4. Publish a security.txt file to facilitate responsible vulnerability disclosure and improve transparency.
  5. Enhance accessibility compliance to improve user experience for all users, including those with disabilities.

Technical notes

Notes

The website is built using Next.js and React frameworks, indicating a modern, server-side rendered React application. It uses Strapi as a headless CMS for content management and Cloudinary for media hosting. The site integrates Piwik Pro for analytics and Usercentrics for consent management, reflecting a focus on privacy and data protection. Performance metrics indicate a slow load time (~13.5 seconds) with a large page size (~473 KB) and many resources (151), suggesting optimization opportunities. Mobile optimization is good, but accessibility is basic. SEO is well addressed with proper metadata, Open Graph tags, and structured data. The technical stack is robust but could benefit from performance tuning and enhanced security configurations.
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.
