Risk levelMedium

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

Penguin Random House is a leading global book publisher and retailer committed to publishing great books and connecting readers and authors worldwide. The website reflects a mature digital presence with comprehensive content including book catalogs, author information, and curated recommendations. The company targets readers, authors, educators, and book clubs, operating at an enterprise scale within the media industry. Technically, the site is built on WordPress with modern JavaScript libraries such as React and jQuery, hosted on AWS CloudFront, and uses third-party marketing and analytics tools like Tealium and Yottaa. However, the security posture is weakened by the absence of a valid SSL certificate and disabled TLS protocols, which are critical issues that must be addressed to ensure secure user interactions. Privacy compliance is supported by comprehensive privacy and terms of service pages, though no explicit cookie consent mechanism was detected. Overall, the website is professional, trustworthy, and content-rich but requires urgent security improvements.

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

3 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 X-Frame-Options header

      Prevents clickjacking attacks

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

  2. 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 strong market position as a top-tier publisher and book retailer with a broad portfolio of services including book publishing, sales, author events, and audiobook offerings. The business model focuses on content creation and distribution, leveraging digital channels for marketing and sales. The company maintains a robust partnership ecosystem with service domains handling cart, account, and profile management. The website's extensive content and social media integration indicate a well-established brand with high user engagement. Growth indicators include active promotion of new releases, award winners, and curated book lists. Strategic observations suggest opportunities to enhance user trust and security to maintain competitive advantage in the digital marketplace.

Security posture

The current security maturity level is moderate to low due to critical gaps in SSL/TLS implementation. The lack of a valid SSL certificate and disabled TLS protocols expose users to potential data interception and undermine trust. Security headers such as X-XSS-Protection, Content Security Policy, and X-Content-Type-Options are properly configured, indicating awareness of security best practices. However, the absence of HSTS enforcement, OCSP stapling, and session resumption mechanisms limits the effectiveness of transport security. No incident response or vulnerability disclosure information was found, suggesting limited transparency in security operations. Compliance with GDPR is supported by the privacy policy, but cookie consent mechanisms are missing. Overall, the security posture requires immediate remediation of transport layer security and enhanced transparency to reduce business risk.

Recommendations

  1. Install and maintain a valid SSL/TLS certificate to enable HTTPS and protect user data.
  2. Enable modern TLS protocols (TLS 1.2 and TLS 1.3) and disable deprecated versions.
  3. Implement and enforce HTTP Strict Transport Security (HSTS) with includeSubDomains and preload directives.
  4. Enable OCSP stapling and session resumption to improve SSL performance and security.
  5. Add a clear cookie consent mechanism to comply with privacy regulations and enhance user trust.
Technical notes

Notes

The website is built on WordPress CMS with a modern front-end stack including React and jQuery, supported by Yottaa CDN for performance optimization. Hosting is provided via AWS CloudFront, ensuring global content delivery. The site includes responsive design and accessibility features, with SEO optimized metadata and structured data (JSON-LD) for enhanced search engine visibility. Performance metrics were not available, but the use of lazy loading and preloading fonts indicates attention to load optimization. Technical risks include the invalid SSL configuration and lack of session security features, which could impact user trust and compliance. Opportunities exist to modernize security infrastructure and enhance privacy controls to align with industry standards.
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.
