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

Agentur Zentral GmbH is a German web design agency based in Braunschweig specializing in creating modern, SEO-optimized websites primarily for the Mittelstand (small and medium-sized enterprises). With over 10 years of experience, the company offers comprehensive digital services including web design using the Contao CMS, search engine optimization, content creation, and tiered support packages. Their market position is that of a trusted regional agency with a professional online presence and recognized certifications such as Contao Premium Partner. Technically, the website is built on the Contao Open Source CMS platform, utilizing modern web technologies like jQuery and FontAwesome. The site is mobile-optimized, accessible, and performs moderately well. Hosting appears to be managed via kasserver.com nameservers. The site implements HTTPS with secure cookies and a cookie consent mechanism, reflecting good privacy compliance. From a security perspective, the site demonstrates solid practices including CSRF protection and session management cookies. However, explicit security headers are not detected, and no formal security or incident response policies are published. No vulnerabilities or exposed sensitive data were found. Overall, the security posture is good but could be improved with additional headers and formal policies. The overall risk assessment is low, with no signs of malicious content or suspicious WHOIS data. The site is professional, trustworthy, and compliant with GDPR. Strategic recommendations include enhancing security headers, publishing a security policy, and implementing a vulnerability disclosure process to further strengthen trust and security culture.

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

10 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. 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: SMB

      Port 445 (SMB) is publicly accessible - SMB - Windows file sharing, high risk

      What to do: Immediately restrict access to SMB 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: 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

  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 Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

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

Agentur Zentral GmbH operates in the technology sector as a specialized web design and digital services agency targeting the German Mittelstand. Their competitive advantage lies in their long-standing experience, partnership with Contao CMS, and comprehensive service offerings including SEO and content management. Revenue streams likely include project-based website development and recurring support subscriptions (Basis, Plus, Premium). The company maintains an active social media presence and partners with recognized platforms like Contao and Theme Ultimate. Growth indicators include transparent pricing and a focus on sustainable SEO results. The partnership ecosystem is focused on CMS and theme providers, with no detected subsidiaries or parent companies. Overall, the business model is service-oriented with a regional focus and a strong emphasis on quality and compliance.

Security posture

The website exhibits a mature security posture with HTTPS enforced and secure cookie usage. The presence of CSRF tokens and session cookies indicates attention to common web security threats. The cookie consent mechanism aligns with GDPR requirements. However, the absence of explicit security headers such as Content-Security-Policy or X-Frame-Options represents an area for improvement. No incident response or security contact information is published, which could hinder timely vulnerability reporting and mitigation. No vulnerabilities or suspicious indicators were detected in the content or WHOIS data. Overall, the security culture appears adequate for the business size but would benefit from formalized policies and enhanced header configurations.

Recommendations

  1. Implement and configure security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  2. Publish a formal security policy and incident response contact information on the website to improve transparency and readiness.
  3. Create and maintain a vulnerability disclosure program or security.txt file to facilitate responsible reporting of security issues.
  4. Regularly audit third-party scripts and dependencies to ensure no vulnerable libraries are included.
  5. Enhance monitoring and logging capabilities to detect and respond to security incidents promptly.

Technical notes

Notes

The website is built on the Contao CMS platform, leveraging modern front-end technologies such as jQuery and FontAwesome for UI elements. The use of the Theme Ultimate theme indicates a standardized design approach. Hosting is managed via kasserver.com nameservers, suggesting a professional hosting environment. The site is mobile-responsive and optimized for SEO with appropriate meta tags and Open Graph data. Performance is moderate, with no major issues detected. Accessibility features are present but could be further enhanced. The technical stack is stable and well-suited for the agency's service offerings, though opportunities exist to improve security headers and implement advanced performance optimizations.
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.
