LAFRENTZ Baugesellschaft mbH is a specialized construction company based in Hannover, Germany, focusing on park deck renovation, building waterproofing, flood protection, and road marking services. The company targets commercial, public, and private clients with comprehensive services from planning to maintenance. Their market position is that of a niche specialist in construction waterproofing and related services within Germany. The website is professionally designed, mobile-optimized, and provides clear navigation and detailed service descriptions, supporting their business credibility. Technically, the site is built on the 1&1 IONOS Website Editor platform, using modern JavaScript libraries and CDN services, with moderate performance and basic accessibility features. Security posture is adequate with HTTPS enforced but lacks explicit security headers and published security policies. Privacy compliance is weak due to the absence of a privacy policy and terms of service pages, though a cookie consent mechanism is present. Contact information is limited to a phone number with no email or social media links. WHOIS data lacks detailed registrant information, slightly reducing trust but not contradicting the business claims. Overall, the website is a good representation of a small specialized construction business with room for improvement in privacy and security transparency.

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
3 findings rated critical or high. Fix these first.
SSL/TLS
TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.
Critical
Unable to retrieve SSL certificate
Could not establish secure connection to retrieve certificate information
What to do: Check if the server is accessible and SSL/TLS is properly configured
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 X-Frame-Options header
Prevents clickjacking attacks
What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"
This scan found 21 issues across 6 checks. Monitoring re-runs those checks daily, emails you when something material changes and records each fix, so you can show progress.

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.

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.

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 real estate and transportation sectors, providing specialized construction services such as waterproofing, park deck renovation, and road marking. Their business model is service-oriented, focusing on project planning, execution, and maintenance. The website content and imagery indicate a focus on quality and experience, targeting a professional audience including commercial and public sector clients. The lack of detailed WHOIS registrant data and absence of social media presence suggest a smaller scale operation with limited digital marketing. The company appears to maintain a moderate market position with a focus on technical expertise and comprehensive service delivery.
Security posture
The website enforces HTTPS, which is a fundamental security measure. However, it lacks explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options, which are important for mitigating common web vulnerabilities. No security or incident response policies are published, and there is no vulnerability disclosure or security.txt file. No exposed sensitive data or vulnerable libraries were detected in the HTML content. The absence of contact channels for security incidents reduces incident response readiness. Overall, the security posture is moderate but could be significantly improved by implementing standard security headers, publishing security policies, and providing clear incident response contacts.
Recommendations
Publish a comprehensive privacy policy and terms of service pages to improve privacy compliance and legal transparency.
Implement and verify security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance web security.
Create and publish a security.txt file and vulnerability disclosure policy to facilitate responsible security reporting.
Add contact information specifically for security incidents or abuse reports to improve incident response readiness.
Enhance accessibility features and conduct regular security audits to maintain a strong security posture and user experience.

Technical notes
Notes
The website is built using the 1&1 IONOS Website Editor platform, leveraging JavaScript libraries like jQuery, Flexslider, and skrollr for UI effects and sliders. Content is served via Cloudfront and 1&1 IONOS CDNs, supporting moderate performance and good mobile optimization. SEO is supported by proper meta tags and Open Graph data. Accessibility is basic but could be improved. The site does not use a popular CMS like WordPress or Drupal but a proprietary editor platform. No major technical debt or outdated libraries were detected, but the absence of explicit security headers and privacy/legal pages indicates areas for modernization. Hosting is with 1&1 IONOS, a reputable provider. Overall, the technical infrastructure is adequate for a small business website but can benefit from enhanced security and compliance features.
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.
