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

Dach + Holzbau Römhild GmbH is a medium-sized German construction company specializing in restoration, renovation, and new construction of residential, commercial, and agricultural buildings, with a strong focus on monument protection. The company operates as a group of three subsidiaries and has over 110 employees with more than 20 years of experience, positioning itself as a leading regional player. The website reflects a professional business with clear service offerings and a strong emphasis on craftsmanship and quality. Technically, the website uses a combination of legacy and modern web technologies including jQuery 1.8.3, Modernizr, and a custom consent manager for GDPR compliance. The site is well-structured, mobile-optimized, and includes SEO best practices such as meta tags and Open Graph data. However, some technologies like jQuery are outdated and could be updated to improve security and performance. From a security perspective, the site enforces HTTPS and implements cookie consent mechanisms, but lacks explicit security headers and published security policies or incident response information. No vulnerabilities or exposed sensitive data were detected. The WHOIS data is consistent with the business claims, showing no privacy protection and a domain age appropriate for the company's history. Overall, the website is trustworthy, professional, and compliant with privacy regulations, though improvements in security headers and technology updates are recommended to enhance the security posture and maintain trust.

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

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  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)

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 company operates in the construction and restoration sector with a diversified service portfolio including carpentry, roofing, masonry, painting, and insulation. Its market position is strong regionally, supported by over 20 years of continuous operation and a workforce of approximately 110 employees. The business model targets both private and commercial clients across Germany, emphasizing quality craftsmanship and monument preservation. The presence of multiple subsidiaries indicates a structured corporate group. The company leverages social media channels for marketing and engagement but does not appear to use extensive analytics or tracking tools, reflecting a privacy-conscious approach. Growth indicators include a steady project volume (1300+ projects) and a clear focus on employee development and training. Partnerships with hosting providers and external media services are evident but limited to infrastructure support.

Security posture

The website demonstrates a moderate to good security maturity level. HTTPS is enforced, and cookie consent is managed properly, indicating GDPR compliance. However, the absence of security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces the overall security hardening. The use of an outdated jQuery version presents a potential vulnerability vector. No incident response or security policy information is publicly available, which could hinder transparency and preparedness. No signs of malware, phishing, or exposed sensitive data were found. The site does not implement advanced tracking or analytics, reducing privacy risks. Overall, the security posture is adequate but could be improved by updating libraries, adding security headers, and publishing security policies.

Recommendations

  1. Implement standard security headers including CSP, HSTS, X-Frame-Options, and X-XSS-Protection to enhance browser security.
  2. Upgrade jQuery and other JavaScript libraries to the latest stable versions to mitigate known vulnerabilities.
  3. Publish a clear security policy and incident response contact information to improve transparency and preparedness.
  4. Consider adding a security.txt file to facilitate responsible vulnerability disclosure.
  5. Regularly audit and update cookie and privacy consent mechanisms to maintain GDPR compliance and user trust.

Technical notes

Notes

The website is built on a custom or proprietary CMS platform with a technology stack including jQuery 1.8.3, Modernizr 2.6.1, and Slimbox2 for UI components. The site uses a consent manager script version 4.1.4 to handle GDPR cookie consent. Performance is moderate with good mobile optimization and basic accessibility features. SEO is well addressed with proper meta tags, Open Graph, and Twitter card integration. Hosting details are not explicitly disclosed but name servers point to agenturserver domains, indicating a professional hosting provider. The site uses HTTPS with no visible SSL issues. Some technical debt is present due to outdated JavaScript libraries, which should be addressed to reduce security risks and improve maintainability.
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.
