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

FlippingBook is a well-established technology company founded in 2004, specializing in digital publishing solutions that convert PDFs into interactive online flipbooks. The company offers a suite of products including online publishing services, desktop software, automation tools, and mobile sales platforms. Their market position is strong within the digital publishing niche, targeting businesses and professionals seeking enhanced document sharing, branding, and tracking capabilities. The website reflects a mature digital presence with comprehensive product information and customer engagement features. Technically, the website employs modern web technologies such as JavaScript, HTML5, CSS3, and leverages cloud infrastructure including AWS DNS and Cloudfront CDN for performance and reliability. The site is mobile-optimized, accessible, and SEO-friendly, with integrated consent management via OneTrust and tracking through Google Analytics and Bing Ads. The technical infrastructure supports a fast and professional user experience. From a security perspective, the site enforces HTTPS, uses cookie consent mechanisms, and advertises content protection features. While explicit security headers are not fully visible in the provided data, the overall posture is strong with no critical vulnerabilities detected. The domain registration data aligns well with the business claims, enhancing trustworthiness. However, enabling DNSSEC and publishing a vulnerability disclosure policy would further strengthen security transparency. Overall, FlippingBook presents a low-risk profile with a professional and secure online presence. Strategic recommendations include enhancing DNS security, publishing incident response contacts, and expanding security disclosures to maintain and improve trust and compliance.

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

2 findings rated critical or high. Fix these first.

  1. 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
    • High

      Weak SSL Key Length

      SSL certificate uses 384-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

FlippingBook operates in the technology sector, focusing on digital publishing SaaS and software products. Their competitive advantage lies in offering a comprehensive platform that integrates PDF conversion, interactive flipbooks, content protection, and document analytics. Revenue streams likely include subscription services, software licenses, and enterprise solutions. The target customers are businesses requiring digital marketing, sales enablement, and document sharing tools. Growth indicators include a broad product portfolio and active marketing channels. Partnerships with scheduling platforms like Calendly enhance customer engagement. The company maintains a consistent brand and professional content, supporting a strong market presence.

Security posture

The security maturity of FlippingBook is moderate to high. HTTPS is enforced, and cookie consent is managed via a reputable CMP (OneTrust). The site avoids exposing sensitive data and integrates tracking responsibly with user consent. However, the absence of explicit security.txt or vulnerability disclosure pages and incomplete visibility of security headers suggest room for improvement. Incident response readiness is not publicly detailed. Compliance with GDPR is indicated by consent mechanisms and privacy policies. Overall, the security culture appears proactive but could benefit from enhanced transparency and DNS security measures.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS integrity and prevent spoofing.
  2. Publish a dedicated incident response page or provide security contact emails (e.g., security@ or abuse@).
  3. Add a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Explicitly implement and document security headers such as X-Frame-Options and X-Content-Type-Options.
  5. Continue enhancing privacy compliance by detailing data retention policies and user rights.

Technical notes

Notes

The website is built on a modern tech stack with extensive use of JavaScript and CSS, served via AWS Cloudfront CDN for optimized performance. Fonts are loaded from Google Fonts with preconnect optimizations. Consent management is implemented using OneTrust scripts, and analytics/tracking are integrated via Google Analytics, Google Tag Manager, and Bing Ads. The site is mobile responsive and accessible, with structured data (JSON-LD) for SEO and business information. No CMS is explicitly detected, suggesting a custom or proprietary platform. Performance is fast, and the site uses canonical and hreflang tags for SEO. Technical risks are minimal but could be reduced by enabling DNSSEC and improving security header coverage.
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.
