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

5 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
    • 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';…

  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

  3. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security

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 media sector with a business model centered on digital advertising services. It leverages partnerships with major advertising and analytics providers like Google to deliver targeted marketing campaigns. The absence of detailed contact information and registrant data suggests a focus on privacy and possibly a smaller operational scale. The website content is well-structured and localized for the German market, indicating a clear target audience and market positioning. The use of cookie consent and GDPR compliance mechanisms demonstrates awareness of regulatory requirements.

Security posture

The website employs HTTPS with good SSL configuration, ensuring secure communication. Cookie consent is managed comprehensively via Cookiebot, supporting GDPR compliance. However, the site lacks visible advanced security headers and does not publish explicit security policies or incident response information. No vulnerabilities or exposed sensitive data were detected in the analysis. The security posture is solid for a small business but could be improved by adding security.txt, enhanced HTTP headers, and public security policies to increase transparency and trust.

Recommendations

  1. Implement additional HTTP security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to enhance protection against common web attacks.
  2. Publish a security.txt file to facilitate responsible vulnerability disclosure and improve security transparency.
  3. Add explicit security and incident response policies on the website to demonstrate preparedness and compliance.
  4. Consider providing clear company contact information including emails and phone numbers to improve business credibility and user trust.
  5. Regularly review and update third-party scripts and plugins to mitigate risks from vulnerable libraries.

Technical notes

Notes

The website is built on WordPress CMS and uses Google Tag Manager and Cookiebot for analytics and cookie management. The site loads a variety of scripts asynchronously, improving performance. The design is responsive and optimized for mobile devices, with good SEO practices evident from meta tags and structured data usage. Performance is moderate, with room for optimization. Accessibility features are basic but present. The technical stack is modern and appropriate for a small digital media agency, though some technical debt may exist in the form of missing advanced security headers and incomplete contact information.
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.
