Security score

28/100

Risk levelHigh

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

Zahnwerkstatt Selz is a small local dental workshop based in Germany, currently operating a website that is under construction. The site provides minimal information, primarily contact details including a phone number and an email address. The business appears to target local dental patients, offering dental care and workshop services. The website's market position is that of a small local dental practice with limited digital presence. Technically, the website is hosted on an Apache server with static HTML and CSS, lacking modern web technologies or CMS platforms. Performance and mobile optimization are poor, and the site lacks accessibility and SEO best practices. Critically, the website does not have a valid SSL/TLS certificate, serving content over HTTP only, which severely impacts security and trust. From a security perspective, the absence of HTTPS, security headers, and privacy policies indicates a low security posture. No vulnerabilities such as malware or phishing were detected, but the lack of basic security controls and compliance measures is a significant concern. The WHOIS data is consistent with a legitimate small business domain registration, with no suspicious patterns. Overall, the website presents a high risk due to lack of encryption and privacy compliance, minimal content, and poor technical implementation. Strategic improvements are necessary to enhance security, privacy, and user trust before the site can be considered professional or reliable.

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

    • Critical

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

  2. 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

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

  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 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"

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 business operates in the healthcare sector as a dental workshop serving local clients in Germany. Its business model is focused on providing dental services locally, with no evident online sales or e-commerce functionality. The website's minimal content and lack of digital marketing tools suggest limited online engagement or growth initiatives. There are no detected partnerships or subsidiaries, and no external domains linked. The company currently lacks visible certifications or trust indicators on its website, which may affect competitive positioning. The business appears to be in an early or transitional phase, as indicated by the under construction status of the website.

Security posture

The current security maturity level of the website is low. The absence of HTTPS is a critical vulnerability that exposes users to data interception and undermines trust. No security headers or incident response contacts are present, and there is no evidence of GDPR or other compliance measures. The lack of privacy and cookie policies further highlights compliance gaps. While no active vulnerabilities or malware were detected, the overall security posture is inadequate for a healthcare-related business handling potentially sensitive information. Incident response readiness is non-existent, and no security culture indicators are visible. Immediate remediation is required to implement encryption, security headers, and privacy compliance.

Recommendations

  1. Implement a valid SSL/TLS certificate to enable HTTPS and secure user connections.
  2. Develop and publish comprehensive privacy and cookie policies to comply with GDPR and build user trust.
  3. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection.
  4. Establish incident response contact channels (e.g., security@ or abuse@ email addresses) for security reporting.
  5. Improve website content quality, design, and mobile optimization to enhance user experience and professionalism.
Technical notes

Notes

The website is hosted on an Apache/2.4.63 Unix server with static HTML and CSS content. There is no evidence of CMS usage or modern web frameworks. The site lacks performance optimization, mobile responsiveness, and accessibility features. No analytics or tracking technologies are implemented. DNS records indicate standard configuration without DNSSEC or CAA records, and no subdomain takeover vulnerabilities. The SSL configuration is absent, with no TLS protocols or cipher suites enabled. The hosting provider appears to be rzone.de. Overall, the technical infrastructure is basic and outdated, requiring modernization to meet current web standards and security 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.
