Aachen-Kalender.de is a localized event calendar platform focused on providing comprehensive listings of cultural, sports, and community events in Aachen and its surrounding region. The website targets residents and visitors interested in staying informed about local happenings. It leverages WordPress CMS with popular plugins such as The Events Calendar and Yoast SEO to deliver structured event data and optimized search engine presence. The platform offers event search, filtering, and calendar export features, enhancing user engagement and utility. Technically, the website is built on a modern WordPress infrastructure with Elementor for design and jQuery for interactivity. It employs HTTPS with proper security headers, ensuring secure data transmission and basic protection against common web threats. The site is mobile-optimized and provides good accessibility and SEO features, although some accessibility enhancements could be beneficial. From a security perspective, the site demonstrates good practices such as HTTPS enforcement and security headers but lacks explicit privacy and cookie policies, as well as incident response contact information. No vulnerabilities or suspicious activities were detected in the provided content. The absence of cookie consent mechanisms and privacy documentation represents compliance gaps, particularly under GDPR regulations. Overall, Aachen-Kalender.de is a trustworthy and professionally maintained local event platform with solid technical foundations. To enhance its security posture and regulatory compliance, it should implement comprehensive privacy and cookie policies, introduce consent mechanisms, and provide clear incident response contacts.

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

    • 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • OWASP A04:2025
      • ASVS V3.4.1
    • High

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 platform occupies a niche as a local event aggregator for the Aachen region, serving cultural institutions, event organizers, and the general public. Its business model revolves around providing free access to event information, likely supported by partnerships with local organizations and venues. The site links to numerous regional partners, indicating a strong local network. Its competitive advantage lies in comprehensive event coverage and integration with popular calendar formats. Growth potential exists in expanding event categories and enhancing user engagement through personalized features. The absence of monetization details suggests a focus on community service or indirect revenue streams such as advertising or sponsorships.

Security posture

The website exhibits a moderate to good security maturity level with HTTPS and multiple security headers in place. No exposed sensitive data or vulnerable libraries were identified. However, the lack of privacy and cookie policies, absence of a cookie consent mechanism, and missing incident response contact information highlight compliance and operational gaps. These issues could expose the organization to regulatory risks and reduce user trust. The site does not appear to use extensive tracking or analytics, which reduces privacy risks but also limits data-driven security insights. Overall, the security posture is adequate for a public informational site but requires improvements to meet GDPR and best practice standards fully.

Recommendations

  1. Implement a comprehensive privacy policy detailing data collection, usage, and user rights.
  2. Add a cookie policy and deploy a cookie consent banner to comply with GDPR requirements.
  3. Publish terms of service to clarify user and platform responsibilities.
  4. Provide clear incident response and security contact information (e.g., security@ or abuse@ email).
  5. Enhance accessibility features to improve usability for all users and meet WCAG guidelines.

Technical notes

Notes

The website is built on WordPress with Elementor and The Events Calendar plugin, indicating a mature and widely supported technology stack. It uses jQuery and Bootstrap Datepicker for UI components. The site is served over HTTPS with appropriate security headers, contributing to a secure browsing experience. Performance appears moderate, with some lazy loading and caching implied by the use of modern plugins. SEO is enhanced by Yoast SEO and structured data (JSON-LD) for events, improving search engine visibility. Mobile optimization is good, with responsive design elements. No major technical debt or outdated libraries were detected in the provided content. Opportunities exist to improve accessibility and add privacy compliance features.
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.
