Blaetterbuch is a specialized technology provider offering professional online flipbook solutions that digitize print media such as flyers, catalogs, and brochures with realistic page-turning effects. Their service targets businesses seeking to extend the reach of their print publications into digital formats accessible across all major browsers and mobile devices. The company positions itself as a niche provider with a comprehensive service including hosting, customization, and integration of multimedia elements like videos and links. Technically, the website employs a modern web stack including Bootstrap, jQuery, and popular UI libraries such as Owl Carousel and Revolution Slider. The site is mobile-optimized and features a custom CMS backend indicated by dynamic content calls. While performance is moderate, the site is well-structured with good SEO and accessibility basics. From a security perspective, the site uses HTTPS (assumed from URL), implements cookie consent mechanisms, and provides a comprehensive privacy policy compliant with GDPR. However, explicit security headers and incident response policies are not evident, suggesting room for improvement in security posture.

Strategic recommendations include enhancing security headers, publishing a security policy, and improving technical performance for a stronger security and user experience profile.

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

8 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

Blaetterbuch operates in the digital publishing technology sector, focusing on converting print media into interactive online flipbooks. Their business model is service-oriented, providing SaaS-like hosting and customization for clients. The company targets a broad audience including businesses and organizations that produce brochures, catalogs, and magazines. Competitive advantages include ease of use, mobile compatibility, and multimedia integration. The company appears small-sized and Germany-based, with no visible parent or subsidiary relationships. Growth potential lies in expanding digital transformation services for print media and enhancing marketing reach through social sharing features.

Security posture

The website demonstrates a moderate security maturity level with HTTPS usage and GDPR-compliant cookie consent. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, the absence of explicit security headers such as Content Security Policy, HSTS, and X-Frame-Options indicates potential gaps. There is no visible incident response or vulnerability disclosure information, which could impact readiness for security incidents. The site lacks a published security policy or dedicated security contact channels. Overall, the security posture is adequate for a small business website but could benefit from enhancements to align with best practices and regulatory expectations.

Recommendations

  1. Implement comprehensive HTTP security headers including CSP, HSTS, and X-Frame-Options to mitigate common web attacks.
  2. Publish a dedicated security policy page outlining security practices and incident response procedures.
  3. Establish and publicize vulnerability disclosure and incident reporting channels to improve transparency and responsiveness.
  4. Conduct regular security audits and update third-party libraries to avoid vulnerabilities.
  5. Optimize website performance and accessibility to enhance user experience and SEO rankings.

Technical notes

Notes

The website is built on a custom CMS platform utilizing standard web technologies such as HTML5, CSS3, JavaScript, jQuery, and Bootstrap. It integrates popular UI components like Owl Carousel and Revolution Slider for interactive content display. The site is mobile-responsive and includes SEO-friendly meta tags and structured content. Performance is moderate, with potential improvements in load times and resource optimization. Accessibility features are basic but present. The technical infrastructure appears stable but could be modernized with enhanced security configurations and performance tuning to reduce technical debt and improve scalability.
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.
