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

Termine.de AG operates a German-language online platform focused on event discovery and appointment booking services. The website positions itself as a leading calendar and event service in Germany, offering users the ability to find events, book appointments online, and create or share calendars. The business model includes services for both consumers and companies, such as online booking tools and location/event publishing. The platform targets a broad general audience in Germany, emphasizing ease of use and comprehensive event coverage. Technically, the website is built using Angular 14, leveraging modern web technologies including Google Fonts, Google Adsense, Google Tag Manager, and Leaflet.js for interactive maps. The site demonstrates good mobile optimization and a professional design, although accessibility features are basic. Performance is moderate, with proper meta tags and SEO considerations in place. From a security perspective, the site enforces HTTPS and uses secure Google services for advertising and analytics. However, explicit security headers like Content-Security-Policy and X-Frame-Options are not evident in the HTML, and no dedicated security or incident response policies are published. The cookie consent mechanism is implemented via Google Funding Choices, indicating some level of GDPR compliance, though no explicit privacy or terms of service pages were found in the provided content. Overall, the website presents a trustworthy and professional front with moderate security maturity. The lack of explicit privacy and security policies, as well as missing direct contact information, are areas for improvement. Strategic recommendations include publishing comprehensive privacy and terms documents, enhancing security headers, and providing clear contact channels for security incidents to strengthen compliance and user trust.

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

4 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 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 Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  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.

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

Termine.de AG is positioned as a key player in the German event and appointment booking market, offering a comprehensive calendar platform and online booking tools for businesses. Its competitive advantage lies in combining event discovery with direct booking capabilities and calendar sharing features. The business model likely generates revenue through premium calendar upgrades, business listings, and advertising via Google Adsense. The target customers include general consumers seeking events and appointments, as well as businesses wanting to offer online booking and increase visibility. The presence of an Area Manager program suggests a strategy to expand regional market penetration. Partnerships with Google services enhance marketing and analytics capabilities. Growth indicators include a modern web platform and integration of multiple services, though detailed financial or founding data is not available.

Security posture

The website demonstrates a moderate security posture with mandatory HTTPS usage and integration of reputable third-party services for ads and analytics. However, the absence of explicit security headers such as Content-Security-Policy, X-Frame-Options, and others reduces the defense-in-depth level. No visible vulnerabilities or exposed sensitive data were detected in the HTML content. The lack of published security policies, incident response contacts, or vulnerability disclosure mechanisms indicates limited transparency and preparedness for security incidents. GDPR compliance is partially addressed through cookie consent mechanisms but lacks explicit privacy documentation. Overall, the security maturity is adequate for a medium-sized web platform but requires enhancements in policy publication, header implementation, and incident readiness to meet higher compliance and security standards.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service pages prominently linked on the website.
  2. Implement and configure security headers such as Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, and Referrer-Policy.
  3. Provide clear contact information including a dedicated security or abuse email address for incident reporting.
  4. Enhance accessibility features to improve compliance and user experience for all users.
  5. Regularly audit third-party scripts and dependencies to mitigate risks from external libraries.

Technical notes

Notes

The website is built on a modern Angular 14 framework, utilizing Google Fonts, Font Awesome 6, Material Icons, and Leaflet.js for mapping features. It integrates Google Adsense and Google Tag Manager for advertising and analytics, indicating a mature digital marketing approach. The site is mobile optimized with responsive design and uses semantic meta tags for SEO. Performance is moderate, with room for improvement in loading speed and accessibility. No CMS is explicitly detected, suggesting a custom or SPA architecture. Hosting provider details are not disclosed. The technical stack is contemporary but could benefit from enhanced security configurations and accessibility improvements to reduce technical debt and improve operational resilience.
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.
