0–100, higher is better. How it is calculated

RDN Agentur für Public Relations GmbH und RDN Verlags GmbH is a small German media and public relations company specializing in creative, multimedia services including website development, press work, social media management, and publishing. Their market position is that of a regional niche agency and publisher serving business clients seeking professional media and PR solutions. The website reflects a professional and consistent brand image with clear contact information and social media presence, supporting business credibility. Technically, the website uses modern Bootstrap 5.3.2 for responsive design and includes JavaScript for interactivity. The site is moderately performant and mobile-optimized but lacks advanced accessibility features and SEO optimization. No CMS or hosting provider details are evident. No analytics or tracking scripts were detected, indicating a privacy-conscious approach. From a security perspective, the site is accessible over HTTPS (assumed from URL), but no security headers were detected, and no explicit security policies or incident response contacts are provided. The site lacks a cookie consent mechanism despite having a GDPR-compliant privacy policy. No forms or data collection points were found on the homepage, reducing attack surface. WHOIS data is consistent with the business claims, showing no privacy protection and legitimate DNS configuration. Overall, the website presents a moderate security posture with room for improvement in security headers, cookie consent, and incident response transparency. The business credibility is strong, but technical and privacy compliance aspects could be enhanced to improve trust and compliance.

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

7 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

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

RDN operates in the media sector as a small-sized agency and publisher focused on public relations and multimedia content production. Their competitive advantage lies in offering a comprehensive suite of services from website creation to social media and publishing, targeting businesses needing professional PR and media solutions. Revenue streams likely derive from service contracts and publishing activities. The company maintains an active social media presence on Facebook, Instagram, and LinkedIn, indicating engagement with clients and partners. No direct partnerships or subsidiaries were identified from the website or WHOIS data. Growth indicators are not explicit but the professional presentation and service diversity suggest stable operations within their niche.

Security posture

The current security maturity level is basic. The website is accessible without WAF or blocking mechanisms and uses HTTPS, but lacks important security headers such as Content-Security-Policy and X-Frame-Options. No vulnerability disclosures or incident response contacts are provided, limiting transparency. The absence of cookie consent mechanisms despite GDPR privacy policy indicates partial compliance. No exposed sensitive data or vulnerable libraries were detected, and no forms on the homepage reduce risk exposure. Overall, the security posture is adequate for a small business but requires enhancements to meet higher compliance and security standards.

Recommendations

  1. Implement a comprehensive cookie consent mechanism to ensure GDPR compliance.
  2. Add security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to improve security posture.
  3. Publish a security policy and provide incident response contact information to enhance transparency and trust.
  4. Conduct regular security audits of third-party scripts and libraries to identify and mitigate vulnerabilities.
  5. Enhance accessibility and SEO features to improve user experience and search engine visibility.

Technical notes

Notes

The website is built using Bootstrap 5.3.2 and custom JavaScript, providing a responsive and modern front-end framework. No CMS or backend technologies were detected from the provided data. The site loads external CSS and JS from trusted CDNs (jsdelivr.net). Performance is moderate with good mobile optimization but basic accessibility and SEO. No analytics or tracking scripts were found, indicating minimal data collection. Hosting provider details are not disclosed. The technical implementation is solid for a small business website but could benefit from improved accessibility, SEO, and security header implementation.
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.
