Risk levelLow

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

YUMPU operates as a digital publishing platform specializing in the release and distribution of magazines, documents, and catalogs worldwide. The platform offers free publishing services aimed at helping publishers gain new readers and customers globally. The website is professionally designed with a modern tech stack including Bootstrap and Swiper, and integrates advertising and analytics tools such as Advertserve and Google Tag Manager. Despite the professional presentation, the absence of WHOIS registration data raises concerns about domain legitimacy and ownership transparency. Security posture is moderate with HTTPS enabled but lacks important security headers and explicit privacy or terms of service documentation. Contact information and compliance details are not readily available, which may impact user trust and regulatory 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

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. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Medium

      Privacy policy may not be GDPR compliant

      Privacy policy lacks explicit GDPR compliance elements

      What to do: Update privacy policy to explicitly address GDPR requirements and user rights

  3. 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

  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 targets publishers and readers globally, positioning itself as a technology-driven platform for digital magazine publishing. Its business model revolves around providing free and paid publishing services to attract a broad user base. The platform leverages advertising and tracking technologies to monetize and analyze user engagement. The lack of visible company registration or contact details suggests a need for improved transparency. Market positioning appears solid within the digital publishing sector, but verification of domain registration and business credentials is advised to strengthen credibility.

Security posture

The website benefits from HTTPS encryption, ensuring secure data transmission. However, the absence of key security headers such as Content-Security-Policy and X-Frame-Options reduces protection against common web attacks. No vulnerability disclosure or incident response information is provided, limiting the ability to report or manage security issues effectively. The use of third-party advertising and tracking scripts introduces potential privacy risks. Overall, the security maturity is moderate but could be significantly improved by implementing best practices and transparency measures.

Recommendations

  1. Implement and publish comprehensive privacy, cookie, and terms of service policies to enhance compliance and user trust.
  2. Add visible and verified contact information including company emails and phone numbers to improve business credibility.
  3. Deploy security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen web security.
  4. Establish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  5. Verify and update WHOIS registration information to ensure domain legitimacy and reduce suspicion.

Technical notes

Notes

The website uses a modern frontend stack with Bootstrap 5.2 and Swiper 8 for responsive design and interactive elements. Google Tag Manager and Usercentrics scripts indicate integration of analytics and consent management tools. Performance is moderate with good mobile optimization. However, the lack of detected CMS or hosting provider information limits full infrastructure assessment. Accessibility features are basic, and SEO optimization is good with proper meta tags and Open Graph data. Technical debt appears low but could be improved with enhanced security configurations and compliance documentation.
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.
