Dr. Andreas Riedler Facharzt für HNO, Kopf- und Halschirurgie · Healthcare · Austria

High risk. 6 critical or high findings in GDPR outside view, SSL/TLS and 1 other check.

Security score

48/100

Risk levelHigh

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

Dr. Andreas Riedler operates a specialized ENT medical practice based in Wels, Austria, providing comprehensive ear, nose, and throat healthcare services including examinations, therapies, and surgeries. The website targets local patients seeking trusted medical care and emphasizes personalized patient relationships and appointment scheduling. Technically, the website is built on a CMS platform (ZMS) with standard web technologies and integrates Matomo analytics for user behavior tracking with privacy opt-out features. However, the absence of a valid SSL certificate and lack of modern TLS protocols represent significant security weaknesses that undermine user trust and data protection. Privacy and cookie policies are present but basic, and no terms of service or incident response policies are published. Overall, the website is functional and professionally presented but requires urgent security improvements to meet modern standards.

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

6 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

    • 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. 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 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';…

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 is a small healthcare provider focused on ENT services in a regional market. It maintains a professional online presence with clear contact details and structured service information. The practice leverages membership in medSV as a trust indicator. The business model is direct patient care with revenue from medical services. There is no evidence of parent companies or subsidiaries. The website's marketing and analytics tools are modest, reflecting a focus on patient engagement rather than aggressive digital marketing. Growth potential may be limited by local market size but supported by personalized service and reputation.

Security posture

The security posture is weak due to the lack of HTTPS and TLS support, exposing visitors to potential interception and data integrity risks. Security headers are partially implemented but insufficient without SSL. No incident response or vulnerability disclosure policies are published, indicating limited security governance. The use of Matomo with opt-out shows some privacy consideration, but overall compliance with GDPR and modern security best practices is lacking. Immediate remediation of SSL and TLS is critical to reduce risk and improve trust.

Recommendations

  1. Install and maintain a valid SSL/TLS certificate to enable HTTPS across the entire site.
  2. Enable modern TLS protocols (TLS 1.2 or TLS 1.3) and configure strong cipher suites.
  3. Enhance security headers with includeSubDomains and preload for HSTS.
  4. Publish clear incident response and vulnerability disclosure policies.
  5. Improve privacy policy to explicitly address GDPR compliance and data retention.
  6. Regularly audit and update analytics and tracking to ensure minimal privacy impact.
  7. Consider adding terms of service to clarify user and business obligations.

Technical notes

Notes

The website runs on nginx with a CMS platform (ZMS) and uses JavaScript and CSS for frontend presentation. Matomo analytics is integrated for event and page tracking with a privacy opt-out mechanism. The site lacks a valid SSL certificate and does not support any TLS protocols, which is a critical technical deficiency. Performance metrics are missing, but chunked transfer encoding is used. The site is mobile optimized and accessible with good navigation and SEO meta tags. Hosting provider details are not explicitly identified. Technical modernization and security hardening are recommended to improve reliability and user trust.
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.
