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

Mystery Themes is a specialized WordPress theme provider established in 2015, offering a portfolio of free and premium themes tailored for various website niches such as eCommerce, blogging, and business. The company targets individuals, freelancers, agencies, and website owners seeking customizable, SEO-optimized themes compatible with popular page builders like Elementor and Gutenberg. Their market position is supported by a sizable user base exceeding 100,000 active websites and positive customer testimonials. Technically, the website is built on WordPress with a modern tech stack including jQuery, Google Analytics, and Yoast SEO. The site demonstrates good mobile optimization, SEO practices, and moderate performance. Hosting is inferred to be with NameCheap based on WHOIS data. The site integrates various marketing and analytics tools, including MonsterInsights and WPfomify, and uses Freemius for payment processing. From a security perspective, the site enforces HTTPS and employs domain transfer protection but lacks DNSSEC and explicit security headers like Content Security Policy. No public security policy or incident response contacts are provided, which represents an area for improvement. Forms are secured with nonce tokens, and no sensitive data exposure was detected. Overall, the website is professional, trustworthy, and content-rich, with minor gaps in privacy compliance such as the absence of a cookie consent mechanism. Strategic recommendations include enabling DNSSEC, implementing CSP headers, adding a security.txt file, and enhancing privacy compliance disclosures.

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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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

Mystery Themes operates in the WordPress theme development sector, focusing on delivering both free and premium themes with a strong emphasis on customization, SEO, and compatibility with popular WordPress tools. Their business model revolves around theme sales, support, and theme bundles. The company has cultivated a loyal customer base and maintains an active presence on multiple social media platforms, enhancing brand visibility and customer engagement. Partnerships with sites like wpallresources.com and payment processing via Freemius indicate a well-integrated ecosystem. Growth indicators include a large number of active websites using their themes and consistent content updates via blogs and tutorials.

Security posture

The security posture of Mystery Themes is moderate. The site uses HTTPS and domain transfer protection, which are fundamental security measures. However, the absence of DNSSEC and Content Security Policy headers reduces the overall security robustness. There is no publicly available security policy or incident response information, which could hinder timely vulnerability reporting and response. The site does not expose sensitive information and uses secure form handling practices. Privacy compliance is partially addressed with GDPR compatibility claims but lacks visible cookie consent mechanisms. Overall, the security culture appears basic but functional, with room for enhancements to meet higher compliance and security standards.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Implement Content Security Policy (CSP) headers to mitigate cross-site scripting and related attacks.
  3. Publish a security.txt file to facilitate responsible vulnerability disclosure and improve incident response.
  4. Add a cookie consent banner or mechanism to comply fully with GDPR and other privacy regulations.
  5. Provide explicit security and incident response contact information on the website to enhance trust and compliance.

Technical notes

Notes

The website is built on a WordPress CMS platform using a combination of PHP, jQuery, and modern JavaScript libraries. It integrates SEO tools like Yoast SEO and analytics services such as Google Analytics and MonsterInsights. The site uses WooCommerce for e-commerce functionality and supports popular page builders like Elementor and Gutenberg. Performance is moderate with deferred JavaScript loading and minified CSS/JS assets. Mobile optimization is good, and the site employs standard accessibility features. Hosting is likely provided by NameCheap, inferred from WHOIS data. Technical risks include lack of DNSSEC and missing advanced security headers, which could be addressed to reduce attack surface.
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.
