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

5 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 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';…

  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. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

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 forum supports the booklooker.de marketplace by providing a platform for user interaction, support, and information exchange. Its market position is that of a niche community hub for book lovers and sellers, enhancing customer retention and satisfaction. The business benefits from a loyal user base and active discussions, which likely contribute to marketplace trust and sales. Revenue streams are indirect, supporting the main e-commerce platform rather than direct monetization. The absence of advertising and tracking suggests a focus on user experience over monetization. The partnership with booklooker.de is clear and integral. Growth indicators include active recent posts and a large number of registered users. Strategic observations include opportunities to improve privacy compliance and security transparency to enhance user trust further.

Security posture

The website demonstrates a moderate security maturity level. HTTPS is used, and login forms are secured with password fields. However, no explicit security headers (e.g., CSP, HSTS) are detected, and there is no visible security policy or incident response information. The lack of a vulnerability disclosure policy or security.txt file indicates limited formal security governance. No vulnerabilities or exposed sensitive data were found in the HTML content. Compliance with GDPR is implied by the presence of a privacy policy, but cookie consent mechanisms are missing. Incident response readiness and security culture indicators are not evident from the content. Overall, the security posture is adequate for a community forum but could be improved with formal policies and enhanced technical controls.

Recommendations

  1. Implement and publish a comprehensive cookie consent mechanism to comply with GDPR and enhance user transparency.
  2. Add security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options to improve technical security posture.
  3. Publish a formal security policy and incident response plan accessible to users to demonstrate security governance.
  4. Establish a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  5. Consider adding contact phone numbers and physical address information to improve business credibility and user trust.

Technical notes

Notes

The website uses phpBB, a mature and widely used forum software, customized with a 'booksilver' theme and German language support. The frontend includes jQuery 3.7.1 and Font Awesome for icons, indicating a modern but not cutting-edge tech stack. The site is served over HTTPS as indicated by canonical URLs, but no explicit security headers were found in the HTML content. Hosting is likely provided by servers associated with the nameservers ns1.your-server.de and ns3.second-ns.de. Performance is moderate with no explicit indicators of optimization or CDN usage. Mobile optimization is good, with responsive menus and layouts. Accessibility is basic, with skip links and ARIA roles present but no advanced features detected. SEO is basic with canonical tags and meta viewport but no Open Graph or JSON-LD structured data found. Overall, the technical infrastructure is stable and functional but could benefit from modernization and enhanced security configurations.
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.
