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

etermin GmbH operates an online appointment scheduling platform primarily targeting German-speaking businesses and service providers. Their solution integrates appointment booking functionality into existing websites and Google search results, positioning them as an innovative player in the SaaS scheduling market. The website is professionally designed with good content quality and clear navigation, supporting a positive user experience. Technical infrastructure includes modern JavaScript libraries such as jQuery and tracking tools like Google Analytics and Bing Ads, indicating a mature digital presence. Privacy and cookie policies are implemented with GDPR compliance, reflecting attention to regulatory requirements. However, the absence of WHOIS data raises concerns about domain registration legitimacy, which should be addressed to enhance trust. Security posture is moderate with HTTPS enforced but lacks visible security headers and explicit security policies. Overall, the website demonstrates a solid business and technical foundation but would benefit from improved transparency and security hardening.

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. 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"

    • 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';…
  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

  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 specialized SaaS provider in the appointment scheduling sector, leveraging integration with Google search to enhance customer reach. Their business model focuses on providing online booking tools to small and medium-sized enterprises, likely generating revenue through subscription plans. The presence of an Innovationspreis IT award suggests recognition in the technology space, supporting market credibility. The target audience includes businesses requiring efficient appointment management, such as healthcare providers, consultants, and service industries. Marketing efforts utilize Bing Ads and Google Tag Manager, indicating active digital marketing strategies. The lack of visible physical addresses or phone numbers on the main site may limit direct customer engagement channels. No evident partnerships or subsidiaries were identified from the data.

Security posture

The website enforces HTTPS, ensuring encrypted communications, and implements cookie consent mechanisms aligned with GDPR. However, the absence of key HTTP security headers such as Content Security Policy (CSP), Strict-Transport-Security (HSTS), and X-Frame-Options reduces defense-in-depth. No vulnerability disclosure or incident response policies are publicly available, which could hinder timely security issue management. The use of third-party scripts like Google Analytics and Bing Ads introduces potential tracking and privacy considerations but is managed with consent banners. No critical vulnerabilities or exposed sensitive data were detected in the provided content. Security maturity appears moderate but could be enhanced by adopting best practices in header configuration, security policy transparency, and vulnerability management.

Recommendations

  1. Implement comprehensive HTTP security headers including CSP, HSTS, and X-Frame-Options to strengthen security posture.
  2. Publish a formal vulnerability disclosure policy and security.txt file to facilitate responsible reporting and incident response.
  3. Verify and publish accurate WHOIS domain registration information to improve domain legitimacy and trust.
  4. Enhance accessibility features to meet recognized standards and improve user inclusivity.
  5. Expand contact information with verified company phone numbers and physical addresses to increase business credibility.

Technical notes

Notes

The website uses a modern tech stack with jQuery 3.6.0 and integrates Google Tag Manager and Bing Ads for analytics and marketing. The CSS indicates use of responsive design techniques, supporting good mobile optimization. No CMS or hosting provider details were detected. Performance is moderate, with potential for improvement by optimizing third-party scripts and assets. SEO is supported by proper meta tags and viewport settings. Accessibility is basic, with room for improvement in semantic markup and ARIA attributes. No critical technical debt or deprecated technologies were observed, but security header absence is a notable technical gap.
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.
