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

The Verbund der Öffentlichen Bibliotheken Berlins (VÖBB) operates as the central public library network in Berlin, providing access to over 80 libraries including mobile and school libraries, alongside extensive digital offerings. The website serves as a portal for catalog search, event information, and user account management, targeting Berlin residents and library users. The business model is public service funded primarily through membership fees and public funding, positioning VÖBB as a key cultural and educational institution in the region. Technically, the site is built on a custom aDIS library management system with JavaScript and CSS, hosted likely by Berlin city administration infrastructure. The site is well-structured, mobile-optimized, and accessible, with professional design and clear navigation. Security posture is solid with HTTPS enforced and session management features, though it lacks some modern security headers and explicit incident response policies. Privacy compliance is good with a comprehensive privacy policy, but no visible cookie consent mechanism is present. Overall, the site is trustworthy, professional, and serves its public mission effectively.

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. 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

    • 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

  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

VÖBB holds a strong market position as Berlin's primary public library network, offering a broad range of services including physical and digital media lending, interlibrary loan, and educational events. Its competitive advantage lies in its extensive network coverage and integration of digital services. Revenue streams are primarily membership fees and public funding. The target customer segment includes general public users, students, and special groups such as refugees. The organization maintains partnerships with cultural and educational institutions and leverages digital tools to enhance user engagement. Growth indicators include active event programming and digital service expansion. Strategic observations highlight the importance of maintaining digital infrastructure and enhancing privacy and security transparency to sustain user trust.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, session timeout warnings, and secure form handling. However, the absence of explicit security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces defense-in-depth. No vulnerabilities or exposed sensitive data were detected in the HTML content. The lack of a published vulnerability disclosure policy or security.txt file indicates room for improvement in incident response readiness. GDPR compliance is supported by a comprehensive privacy policy, but cookie consent mechanisms are missing, which could be a compliance risk. Overall, the security culture appears cautious but could benefit from enhanced transparency and modern security practices.

Recommendations

  1. Implement and publish a cookie consent banner/mechanism to comply with GDPR cookie requirements.
  2. Add security headers such as CSP, HSTS, and X-Frame-Options to strengthen security posture.
  3. Publish a vulnerability disclosure policy or security.txt file to improve incident response transparency.
  4. Include explicit contact information for a Data Protection Officer or security contact to enhance trust.
  5. Regularly audit and update third-party scripts and dependencies to avoid potential vulnerabilities.

Technical notes

Notes

The website is built on a custom aDIS library management system with JavaScript and CSS assets. It uses session management with timeout warnings and AJAX calls for session refresh. The site is mobile-optimized and accessible, with a clear navigation structure and professional design. Hosting appears to be managed by Berlin city administration or an associated provider, indicated by nameservers. Performance is moderate, with room for optimization. No major technical debt or deprecated technologies were detected. Opportunities exist to modernize security headers and enhance privacy compliance features. The technical infrastructure supports the business needs effectively but could benefit from incremental modernization and security hardening.
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.
