Technically, the site leverages modern web technologies including JavaServer Faces with PrimeFaces, jQuery, Bootstrap, and Matomo for analytics, ensuring a responsive and accessible user experience. Security measures include HTTPS usage and a robust cookie consent mechanism, although there is room for improvement in implementing HTTP security headers and publishing explicit security policies.

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

3 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. 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 website operates as a government-backed service, offering a free event listing and management platform that supports cultural and recreational engagement in Linz. Its market position as the official city event calendar provides a competitive advantage, ensuring high trust and usage among target audiences. The business model is non-commercial, focusing on public service rather than revenue generation. The platform's integration with social media channels and event highlight features enhances user engagement and visibility. Growth potential lies in expanding event categories and improving digital services for organizers and users. The partnership ecosystem includes the city government and cultural institutions, reinforcing its authoritative status.

Security posture

The security posture of Linz-Termine is moderate to good. The site uses HTTPS and includes a cookie consent mechanism compliant with GDPR, reflecting awareness of privacy regulations. However, the lack of visible security headers such as Content Security Policy, HSTS, and X-Frame-Options represents an area for enhancement. No incident response or vulnerability disclosure information is provided, which could improve transparency and readiness. The use of Matomo analytics with disabled cookies indicates a privacy-conscious approach. Overall, the site maintains a secure environment suitable for its public-facing role but should adopt additional best practices to strengthen defenses and compliance.

Recommendations

  1. Implement comprehensive HTTP security headers including CSP, HSTS, and X-Frame-Options to enhance protection against common web attacks.
  2. Publish a clear security policy and provide incident response contact information to improve transparency and user trust.
  3. Establish a vulnerability disclosure program or security.txt file to facilitate responsible reporting of security issues.
  4. Regularly audit and update third-party libraries and frameworks to mitigate risks from known vulnerabilities.
  5. Enhance WHOIS data transparency if possible to improve domain trustworthiness and legitimacy perception.

Technical notes

Notes

The website is built on a JavaServer Faces framework with PrimeFaces components, supported by jQuery and Bootstrap for UI responsiveness and styling. It uses Matomo for privacy-focused analytics and Klaro for cookie consent management. The site is mobile-optimized with good accessibility features and SEO metadata including Open Graph and Twitter cards. Performance is moderate, with asynchronous loading of scripts and lazy loading of images. The absence of a detected CMS suggests a custom or proprietary platform. Hosting details are not disclosed. Technical debt appears low, but improvements in security headers and WHOIS transparency are recommended to reduce risks and enhance 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.
