Malerbetrieb Karl Schiener is a small local painting and construction service company based in Johannesberg, Germany. The company offers services including painting, plastering, drywall installation, and thermal insulation. The website is designed to attract local customers seeking these services, emphasizing customer focus and quality craftsmanship. The business operates primarily in the German market and targets residential and commercial clients in the region. Technically, the website is built on the Multiscreensite platform, utilizing modern JavaScript libraries such as jQuery, skrollr for parallax effects, PhotoSwipe for image galleries, and Mapbox for map integration. It employs a CDN for hosting and includes analytics via Snowplow. The site is mobile optimized and includes basic accessibility features, though some improvements could be made. From a security perspective, the site uses HTTPS and includes captcha protection on its contact form to mitigate spam.

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

5 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 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. 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.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

The company positions itself as a local service provider in the painting and construction sector, focusing on quality and customer satisfaction. Its business model is service-oriented, targeting homeowners and businesses in Johannesberg and surrounding areas. The website's content and structure support lead generation through contact forms and direct contact details. There is no evidence of partnerships or subsidiaries. The use of modern web technologies and analytics suggests an interest in digital presence and customer engagement. The absence of terms of service and detailed security policies indicates room for maturity in compliance and risk management.

Security posture

The website demonstrates a basic to moderate security maturity level. HTTPS is enforced, and spam protection via captcha is implemented on the contact form. However, the lack of visible security headers such as Content Security Policy, HSTS, or X-Frame-Options reduces the overall security posture. No incident response or security policy information is provided, which may impact preparedness for security events. The use of up-to-date libraries and absence of exposed sensitive data are positive indicators. Compliance with GDPR is suggested by the presence of privacy and cookie policies with consent mechanisms. Overall, the security posture is adequate for a small business but could benefit from enhancements.

Recommendations

  1. Implement and verify HTTP security headers including Content Security Policy, HSTS, X-Frame-Options, and X-XSS-Protection to improve defense against common web attacks.
  2. Add a dedicated security policy and incident response page with contact information for reporting security issues to enhance transparency and preparedness.
  3. Regularly audit and update third-party libraries and dependencies to mitigate vulnerabilities.
  4. Enhance accessibility features to improve usability for all users and comply with standards.
  5. Create and publish a terms of service page to clarify user rights and responsibilities.

Technical notes

Notes

The website is hosted on a CDN-backed platform (cdn-website.com) and built using the Multiscreensite CMS, which provides a modular and responsive design framework. It uses modern JavaScript libraries such as jQuery 3.7.0, skrollr for parallax scrolling, PhotoSwipe for image galleries, and Mapbox for map integration. Analytics are handled by Snowplow, indicating a moderate level of data collection sophistication. The site loads CSS asynchronously for performance optimization and includes a friendly captcha for form spam protection. Mobile optimization is good, with responsive layouts and viewport settings. However, no explicit accessibility ARIA roles or landmarks beyond basic navigation were detected. Performance is moderate, with some room for improvement in loading speed and resource optimization.
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.
