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

The DRESDEN Science Calendar website serves as an informational platform aggregating scientific lectures and workshops in Dresden, primarily targeting researchers, students, and the interested public. It is operated under the DRESDEN-concept alliance, which includes TU Dresden and other research institutions. The platform offers calendar views, personalized bookmarks, and filtered search capabilities to facilitate event discovery. Technically, the site uses standard web technologies including HTML5, CSS, JavaScript, and jQuery UI components, with moderate performance and good mobile optimization. Security-wise, the site uses HTTPS and secure form submission but lacks visible security headers and explicit privacy or cookie policies, which are areas for improvement. The domain registration aligns well with the institutional affiliation, indicating legitimacy and trustworthiness. Overall, the site is professional, safe, and reliable but could enhance privacy compliance and security posture.

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

10 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

  2. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  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 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';…

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 occupies a niche position as a regional scientific event aggregator, leveraging partnerships with academic and research institutions in Dresden. Its business model is non-commercial, focusing on community engagement and knowledge dissemination. The platform's key competitive advantage is its integration across multiple institutions, providing a centralized calendar for diverse scientific events. The target audience includes academics, students, and the general public interested in science. The partnership ecosystem includes TU Dresden, DRESDEN-concept, the City of Dresden, and a local internet agency. Growth potential lies in expanding event coverage and improving user engagement features. The platform currently lacks monetization streams and focuses on informational value.

Security posture

The website demonstrates a basic to moderate security maturity level. It employs HTTPS and secure form methods, avoiding exposure of sensitive data in the HTML. However, the absence of security headers such as Content-Security-Policy and X-Frame-Options reduces its defense-in-depth. There is no visible vulnerability disclosure or incident response information, which limits transparency for security issues. Privacy compliance is weak due to missing privacy and cookie policies. The site does not appear to use tracking or analytics that might introduce privacy risks. Overall, the security posture is adequate for an informational site but should be enhanced to meet best practices and regulatory requirements.

Recommendations

  1. Implement and publish a comprehensive privacy policy and cookie policy to improve GDPR compliance.
  2. Add security headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen security posture.
  3. Provide clear contact information including a security or abuse contact email to facilitate incident response.
  4. Enhance accessibility features to improve usability for all users.
  5. Consider establishing a vulnerability disclosure policy or security.txt file to increase transparency and trust.

Technical notes

Notes

The website is built with standard web technologies including HTML5, CSS, JavaScript, and jQuery UI components. It uses Google Fonts for typography and includes custom CSS and JavaScript files. The site is mobile responsive and has a clear navigation structure with dropdown menus and search filters. Performance is moderate, with no heavy external dependencies or tracking scripts detected. There is no detected CMS or complex backend framework visible from the front-end code. Hosting details are not explicit but DNS name servers are affiliated with TU Dresden, suggesting institutional hosting. The site could benefit from modernizing some frontend components and improving SEO and accessibility compliance.
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.
