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

YUMPU operates as a digital publishing platform specializing in the online distribution of magazines, documents, and catalogs. The platform targets publishers and businesses seeking to publish and reach a global audience digitally. The website demonstrates a professional design with good content quality and clear navigation, supporting a medium-sized technology/media business model. Technically, the site leverages modern frameworks such as Bootstrap and Swiper.js, with Google Tag Manager for analytics and marketing. The site is mobile optimized and SEO friendly, though accessibility features are basic. Security posture is strong with HTTPS enforced and security headers present, but lacks published security policies or incident response information. Privacy and cookie policies are comprehensive and GDPR compliant, including consent mechanisms. However, the absence of WHOIS data raises concerns about domain legitimacy, which impacts overall trust and business credibility scores. No direct company contact emails or phone numbers were found, limiting direct communication channels. Overall, the site is safe for general audiences and does not contain adult or questionable content.

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

No critical or high findings. These medium findings are worth fixing next.

  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.

    • Medium

      Missing X-XSS-Protection header

      Legacy XSS protection (deprecated but still recommended)

      What to do: Add "X-XSS-Protection: 1; mode=block"

    • Medium

      Missing Permissions-Policy header

      Controls browser features and APIs

      What to do: Implement a Permissions-Policy to restrict feature access

      • OWASP Secure Headers: OWASP Secure Headers Project recommends Permissions-Policy: accelerometer=(), autoplay=(), camera=(), cross-origin-isolated=(),…

  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.

    • Medium

      No MTA-STS Policy

      MTA-STS enforces TLS for email delivery

      What to do: Implement MTA-STS to prevent downgrade attacks

  3. 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.

    • Medium

      SSL Certificate Expires Within 90 Days

      SSL certificate expires in 75 days

      What to do: Plan SSL certificate renewal

  4. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • Medium

      DNSSEC Not Enabled

      DNSSEC is not configured for this domain

      What to do: Enable DNSSEC to prevent DNS spoofing attacks

      • CAPEC-142
      • RFC 4033

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

YUMPU holds a solid position in the digital publishing market, offering free and paid services for online magazine and document publishing. Its business model focuses on enabling content creators and businesses to publish and distribute digital content worldwide. The platform's use of structured data and SEO best practices indicates a mature digital marketing approach. The lack of visible company registration or domain ownership details suggests a need for enhanced transparency. The company appears to rely on Google Tag Manager for analytics and marketing, with no visible affiliate or advertising networks beyond basic tracking. The absence of direct contact information and security policies may affect customer trust and regulatory compliance. Strategic partnerships or subsidiaries were not identified from the data.

Security posture

The website demonstrates a good security posture with HTTPS enabled and multiple security headers implemented, reducing common web vulnerabilities. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the lack of published security policies, incident response plans, or vulnerability disclosure mechanisms limits the site's transparency and readiness for security incidents. The missing WHOIS data is a significant concern for domain legitimacy and trustworthiness. Privacy compliance is strong with GDPR-aligned policies and cookie consent mechanisms. Recommendations include publishing explicit security and incident response policies, establishing a vulnerability disclosure program, and providing data protection officer contact details to enhance compliance and trust.

Recommendations

  1. Publish a dedicated security policy and incident response page to improve transparency and readiness.
  2. Implement and publish a security.txt file to facilitate vulnerability disclosure and responsible reporting.
  3. Provide clear company contact emails and phone numbers on the website to enhance business credibility.
  4. Verify and update domain WHOIS information to ensure domain legitimacy and trust.
  5. Enhance website accessibility features to improve compliance and user experience for all users.

Technical notes

Notes

The website uses a modern frontend technology stack including Bootstrap 5.2.0 for responsive design and Swiper.js for interactive sliders. Google Tag Manager is used for analytics and marketing tag management. The site loads external scripts securely over HTTPS and includes font and icon libraries such as Inter and Font Awesome 5 Pro. Performance is moderate with good mobile optimization and SEO metadata including Open Graph and JSON-LD structured data for enhanced search engine visibility. No CMS or hosting provider details were identified from the HTML content. The site could benefit from improved accessibility features and performance optimizations to further enhance user experience and compliance.
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.
