Low risk. 2 critical or high findings in Security headers and SSL/TLS.

Security score

82/100

Risk levelLow

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

Packt is a technology publishing company offering a vast library of over 7,000 books, videos, and courses aimed at advancing technical skills and careers. Their business model includes direct e-commerce sales and subscription services, enhanced by an AI-powered learning assistant. The website demonstrates a mature digital presence with modern web technologies, structured data for SEO, and a responsive design optimized for mobile users. While the site is professionally designed and content-rich, explicit privacy and terms of service policies are not clearly linked in the provided content. Security posture is solid with HTTPS and consent management, but lacks some advanced security headers and published security policies. WHOIS data is unavailable, which slightly reduces trustworthiness but the overall branding and content quality support legitimacy.

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

2 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 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. 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.

    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

Packt holds a strong position in the technology education sector, targeting developers and IT professionals globally. Their competitive advantage lies in a large, diverse content catalog and innovative AI learning tools. Revenue streams include direct product sales and subscription access. The company maintains active social media channels and uses analytics tools responsibly with consent mechanisms. Growth indicators include frequent new releases and a broad geographic reach via localized site versions. The absence of visible contact details and WHOIS data limits transparency but does not detract significantly from their market presence.

Security posture

The website employs HTTPS and basic consent management for privacy compliance, indicating a baseline security maturity. However, the lack of explicit security headers such as Content Security Policy and HSTS, absence of published security policies or incident response contacts, and no vulnerability disclosure mechanisms suggest room for improvement. No vulnerabilities or exposed sensitive data were detected in the analyzed content. Compliance with GDPR is implied by consent settings but not explicitly documented. Overall, the security posture is moderate with recommendations to enhance transparency and technical controls.

Recommendations

  1. Implement and publish a comprehensive privacy policy and terms of service accessible from all pages.
  2. Add security headers including Content Security Policy, HSTS, and X-Frame-Options to strengthen defense-in-depth.
  3. Publish a security policy and incident response contact information to improve transparency and trust.
  4. Establish a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  5. Enhance WHOIS data availability or domain registration transparency to improve legitimacy perception.

Technical notes

Notes

The website uses a modern technology stack including JavaScript modules, Google Tag Manager, and Google Analytics with consent management. The design is responsive and optimized for mobile devices, with good SEO practices including meta tags and structured JSON-LD data. Performance is moderate with preloading of critical CSS and fonts. No CMS or hosting provider details were detected. The site uses custom-built frontend assets indicating a tailored development approach. Accessibility features appear adequate but could be further audited. Overall, the technical infrastructure supports a professional and scalable digital platform.
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.
