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. 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"

    • 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. GDPR outside view

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

    • 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

  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.

    • 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

Yoast's market positioning as a leading SEO software provider is reinforced by its extensive customer base and integration with major platforms like WordPress and Shopify. Their business model focuses on SaaS and digital product sales, including premium plugins and educational content. The company targets entrepreneurs, marketers, and eCommerce teams seeking to improve search visibility without requiring deep SEO expertise. Strategic partnerships, such as with Newfold Digital, enhance their operational capabilities. The presence of 24/7 premium support and active social media engagement further strengthens customer trust and brand loyalty.

Security posture

The website exhibits a mature security posture with HTTPS enabled and domain registration protections in place. The use of Cloudflare DNS adds resilience, though DNSSEC is not currently enabled, representing an area for improvement. No exposed sensitive data or vulnerable libraries were detected in the analyzed content. Privacy and cookie policies are comprehensive, with active consent mechanisms. However, the absence of a publicly available security policy, incident response plan, and vulnerability disclosure program indicates room for enhancement in security transparency and readiness. Overall, the security maturity is good but could benefit from formalized policies and security contact channels.

Recommendations

  1. Enable DNSSEC to strengthen DNS security and prevent spoofing.
  2. Publish a dedicated security policy and incident response plan on the website.
  3. Establish and publicize a vulnerability disclosure policy and security.txt file.
  4. Provide explicit security contact emails (e.g., security@yoast.com) for reporting issues.
  5. Regularly audit and update third-party scripts and libraries to mitigate vulnerabilities.

Technical notes

Notes

The website is built on a modern and widely supported technology stack centered around WordPress and WooCommerce, enhanced with JavaScript and jQuery libraries. Hosting and DNS services leverage Cloudflare, contributing to fast load times and reliable uptime. The site is well-optimized for mobile devices and accessibility, with comprehensive SEO meta tags and structured data (JSON-LD) implemented for enhanced search engine visibility. Performance is fast, and the site uses advanced marketing and analytics tools such as Google Analytics, Google Tag Manager, and HelpScout. Technical risks are minimal, with no visible outdated or vulnerable components in the provided content. Opportunities exist to further modernize security configurations and formalize 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.
