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

9 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

  2. Network security

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

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection
    • Critical

      Critical Service Exposed: PostgreSQL

      Port 5432 (PostgreSQL) is publicly accessible - PostgreSQL - Database server

      What to do: Immediately restrict access to PostgreSQL using firewall or VPN

      • NIS2 21(2)(e)

      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  3. 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

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 · found on this site
  • 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 agency targets corporate clients and institutions requiring comprehensive marketing and communication services, including print and digital media. Its competitive advantage lies in its long history, combined expertise in both traditional graphic design and modern web technologies, and proprietary software offerings. The business model is service-oriented, focusing on customized solutions and digital transformation for process optimization. The extensive list of references and partner domains indicates a strong market presence and diversified client base. Growth potential exists in expanding digital services and enhancing compliance and security transparency.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and cookie consent mechanisms in place. However, the absence of visible security headers (e.g., CSP, HSTS) and lack of published security or incident response policies indicate areas for improvement. No vulnerabilities or exposed sensitive data were detected in the HTML content. The use of common WordPress plugins necessitates regular updates to mitigate risks. There is no public vulnerability disclosure or security contact information, which could hinder incident response effectiveness. Overall, the security posture is adequate for a small agency but should be enhanced to meet higher compliance standards such as GDPR and NIS2.

Recommendations

  1. Implement comprehensive privacy and cookie policies accessible from the website footer.
  2. Add security headers such as Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, and X-XSS-Protection.
  3. Publish an incident response and vulnerability disclosure policy with dedicated contact channels.
  4. Regularly audit and update WordPress core and plugins to reduce vulnerability risks.
  5. Enhance accessibility features and provide clear data retention and privacy compliance statements.

Technical notes

Notes

The website is built on WordPress CMS, leveraging jQuery, Owl Carousel, and FontAwesome for UI components. SEO is managed via Yoast SEO plugin, and cookie consent is handled by Borlabs Cookie, indicating a modern and compliant technical stack. Hosting appears to be provided by your-server.de with multiple nameservers for redundancy. Performance is moderate with optimized images and responsive design for mobile devices. The site uses structured data (JSON-LD) for enhanced search engine understanding. Technical debt is low, but security headers and explicit privacy documentation are missing, representing modernization opportunities. No critical technical risks were identified from the HTML content.
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.
