Risk levelHigh

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

Jahn, Mack & Partner architektur und stadtplanung mbB is a medium-sized German firm specializing in architecture and urban/regional planning. Founded in 2003, the company offers a broad range of services including architectural design, project and funding management, and communication consulting. Their interdisciplinary team and network of specialized partners position them well in the real estate and planning sector. The website reflects a professional image with clear service descriptions and contact information, targeting public and private investors as well as municipal clients. Technically, the website is built on WordPress with a modern theme and plugins, including Contact Form 7 and GDPR-compliant cookie consent mechanisms. Hosting is provided by 1984hosting.com, and the site uses HTTPS with good SSL configuration. Performance and mobile optimization are adequate, though some improvements in accessibility and security headers could be made. From a security standpoint, the site enforces HTTPS and cookie consent but lacks explicit security policies or incident response information. No vulnerabilities or exposed sensitive data were detected. The WHOIS data shows consistent domain registration with no privacy protection, supporting legitimacy. Overall, the security posture is solid but could benefit from enhanced headers and formal policies. The overall risk is low with no signs of malicious activity or content safety concerns. Strategic recommendations include implementing additional security headers, publishing security and incident response policies, and maintaining up-to-date software to ensure ongoing compliance and protection.

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. 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)

      • 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

  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';…

  3. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

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

Jahn, Mack & Partner operates in the real estate and urban planning sector with a focus on architectural and regional development services. Their business model centers on professional consulting and project management for public and private clients. The company leverages an interdisciplinary team and external networks to deliver comprehensive solutions. Market positioning is stable within Germany, with a medium-sized firm profile and a founding date of 2003 indicating established operations. The website supports business credibility with detailed service offerings and GDPR compliance. No direct partnerships or subsidiaries were identified from the website or WHOIS data. Growth indicators include a broad service portfolio and active project management capabilities.

Security posture

The website demonstrates a mature security posture with mandatory HTTPS and GDPR-compliant cookie consent mechanisms. No security.txt or explicit security policies were found, which limits transparency on incident response readiness. The absence of advanced security headers suggests room for improvement in defense-in-depth strategies. No vulnerable libraries or exposed sensitive data were detected. The lack of analytics or tracking scripts reduces privacy risks. Overall, the site maintains a secure baseline appropriate for its business type but should enhance security documentation and header implementation to improve resilience and compliance.

Recommendations

  1. Implement security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to strengthen browser security.
  2. Publish a security policy and incident response plan on the website to increase transparency and preparedness.
  3. Add a security.txt file to facilitate vulnerability disclosure and improve security communication.
  4. Regularly update WordPress core, themes, and plugins to mitigate risks from known vulnerabilities.
  5. Consider integrating accessibility improvements to enhance usability for all users.

Technical notes

Notes

The website is built on WordPress 6.7.4 with a commercial theme (Uncode) and several plugins including Contact Form 7 and Cookie Law Info. It uses jQuery 3.7.1 and Font Awesome 4.6.3 for UI elements, and Typekit for fonts. Hosting is provided by 1984hosting.com as indicated by nameservers. The site is mobile optimized and performs moderately well. SEO is supported by proper meta tags and structured navigation. No major technical debt or deprecated technologies were detected, but security headers are missing. The site architecture is typical for a professional services firm, balancing content richness with usability and compliance requirements.
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.
