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

4 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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  2. 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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

  3. GDPR outside view

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

    • 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

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

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

Penguin Random House holds a dominant position in the media and publishing sector, leveraging a broad portfolio of books, authors, and series. Their business model centers on publishing, retail, and digital content distribution, targeting general readers and book enthusiasts globally. The company demonstrates strong branding consistency and trust signals through social media presence and author engagement. Partnerships with related domains like readbrightly.com enhance content reach. The enterprise-scale website supports a large user base with e-commerce and account management subsystems. Growth indicators include active promotions and curated content lists. Strategic observations suggest continued investment in digital content and user engagement.

Security posture

The website exhibits a mature security posture with HTTPS and multiple security headers such as HSTS, X-Frame-Options, and Content-Security-Policy. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of a public security policy, incident response contact, or vulnerability disclosure program limits transparency. The use of third-party scripts like Tealium requires ongoing monitoring for vulnerabilities. Data protection practices appear compliant with GDPR, supported by consent mechanisms. Incident response readiness cannot be fully assessed due to lack of public information. Overall, the security culture appears sound but could benefit from enhanced transparency and formalized disclosure channels.

Recommendations

  1. Publish a dedicated security policy and incident response plan on the website.
  2. Implement and publicize a vulnerability disclosure program or security.txt file.
  3. Provide direct security contact information such as security@ or abuse@ email addresses.
  4. Regularly audit and update third-party scripts and libraries to mitigate vulnerabilities.
  5. Enhance transparency around data protection officer contact and data retention policies.

Technical notes

Notes

The website is built on WordPress with a custom theme and uses modern JavaScript libraries including jQuery, Bootstrap, and Slick Carousel for UI components. Tag management and analytics are handled via Tealium, indicating advanced marketing and tracking capabilities. The site is mobile optimized with responsive design and accessibility features. Performance is moderate, with preloading of fonts and asynchronous script loading. SEO is supported by comprehensive meta tags and Open Graph data. Technical risks include reliance on multiple third-party scripts which require continuous security monitoring. The infrastructure appears scalable and well-maintained, suitable for an enterprise-level publishing business.
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.
