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

Issuu Inc. operates a digital publishing platform that transforms PDFs and other document formats into interactive flipbooks and various shareable content types. The platform targets content creators, marketers, publishers, and enterprises, offering tools for content creation, embedding, digital sales, and analytics. It holds a solid market position with integrations to major marketing and design platforms such as Canva, HubSpot, Adobe Express, and Mailchimp. The website is professionally designed, content-rich, and user-friendly, supporting a broad audience with clear navigation and extensive resources. Technically, the site leverages modern frameworks like Next.js and React, served via Fastly CDN and AWS DNS, ensuring scalability and performance. However, the absence of a valid SSL certificate and HTTPS support is a critical security gap that undermines user trust and data protection. Privacy and terms policies are comprehensive and GDPR compliant, reflecting a commitment to privacy compliance. Social media presence and customer testimonials enhance business credibility. Overall, the platform is mature and feature-rich but requires urgent security improvements to meet modern standards.

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

6 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 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 Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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

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

Issuu's business model is SaaS-based, monetizing through tiered subscription plans tailored for individuals and enterprises. The platform's competitive advantage lies in its ease of use, multi-format content conversion, and seamless integrations with popular marketing and design tools. Revenue streams include digital sales commissions, premium features, and enterprise collaboration tools. The target customer segments include individual content creators, marketing teams, publishers, and enterprises seeking scalable digital publishing solutions. Growth indicators include a broad content library, active social media engagement, and a comprehensive resource center. The partnership ecosystem with Canva, HubSpot, Adobe, and Mailchimp strengthens its market reach and product offering. Strategic observations suggest focusing on enhancing security posture and expanding direct contact channels to improve customer trust and support.

Security posture

The current security posture of the website is weak due to the lack of a valid SSL certificate and absence of HTTPS, exposing users to potential data interception and man-in-the-middle attacks. While some security headers like X-Content-Type-Options and X-Frame-Options are present, critical best practices such as HSTS, OCSP stapling, and session resumption are missing. No explicit security policy or incident response information is available, indicating limited transparency in security governance. The site does not expose sensitive data or vulnerable libraries but must urgently address the SSL/TLS deficiencies to protect user data and comply with security standards. Privacy policies are comprehensive and GDPR compliant, but the lack of visible security frameworks or certifications suggests room for improvement in formal security management and incident response readiness.

Recommendations

  1. Implement and maintain a valid SSL/TLS certificate to enable HTTPS across the entire site.
  2. Enable modern TLS protocols (TLS 1.2 and TLS 1.3) and disable deprecated protocols.
  3. Configure HTTP Strict Transport Security (HSTS) with includeSubDomains and preload directives.
  4. Enable OCSP stapling to improve certificate revocation checking performance and security.
  5. Implement session resumption mechanisms such as session tickets or session cache.
  6. Publish a dedicated security policy and incident response plan with contact channels.
  7. Enhance accessibility features and conduct regular security audits to identify vulnerabilities.
  8. Expand direct contact information availability to improve customer support and trust.
Technical notes

Notes

The website is built on a modern React-based framework, Next.js, enabling server-side rendering and optimized performance. It uses Fastly CDN and Varnish caching for content delivery, enhancing scalability and speed. The site includes comprehensive meta tags and SEO optimizations, with responsive design for mobile devices. However, performance metrics are unavailable, limiting assessment of load times and resource efficiency. Accessibility is basic but present, with room for improvement. The absence of a valid SSL certificate is a significant technical risk. The site integrates multiple third-party marketing and analytics tools, including Google Tag Manager and Mixpanel, indicating a mature digital marketing infrastructure. Overall, the technical infrastructure is modern and robust but requires critical security upgrades and performance monitoring enhancements.
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.
