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

Mosaic is a specialized technology company offering an advanced WordPress theme builder and design system aimed at enhancing website design, speed, and functionality. The company targets WordPress users, developers, and designers seeking to overcome design limitations inherent in standard WordPress page builders. The website presents a professional and modern digital presence with excellent design quality and SEO optimization, leveraging WordPress CMS and Yoast SEO plugin technologies. Hosting and domain registration are managed via Cloudflare, ensuring reliable infrastructure and security. Security posture is solid with HTTPS enabled and domain transfer protection, though DNSSEC is not enabled and security headers are absent. Privacy and cookie policies are not found, indicating compliance gaps. No contact information or incident response details are published, limiting direct communication channels. Overall, the site is trustworthy and professional but would benefit from enhanced privacy compliance and security transparency.

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

6 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"

    • 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 Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  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 Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

Mosaic operates in the technology sector, focusing on WordPress theme building solutions. The business model revolves around software product sales and design system services. The domain age (since 2005) supports a mature market presence. The company leverages partnerships with Cloudflare for domain and DNS services and uses Facebook for social media engagement. The absence of contact details and formal policies suggests a lean operation or a focus on digital product delivery without extensive customer support channels. Marketing tools include Yoast SEO and zaraz tracking, indicating a data-driven approach to audience engagement. The company positions itself as a niche provider with a consistent brand and high-quality content, targeting a specialized audience of WordPress professionals.

Security posture

The website demonstrates a good security baseline with HTTPS enforced and domain transfer protection. However, the lack of DNSSEC and security headers such as Content-Security-Policy and Strict-Transport-Security represents missed opportunities to harden security further. No evidence of vulnerability disclosure programs or security policies is found, which could impact incident response readiness and transparency. The absence of contact channels for security incidents reduces trust for security-conscious users. No vulnerabilities or exposed sensitive data were detected in the analyzed content. Overall, the security posture is good but could be improved with standard best practices and policy disclosures.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Implement and publish comprehensive privacy and cookie policies to improve GDPR compliance.
  3. Add standard security headers (CSP, HSTS, X-Frame-Options) to strengthen web security.
  4. Publish a security policy and incident response contact information to improve transparency and trust.
  5. Consider establishing a vulnerability disclosure program and security.txt file to engage security researchers.

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.
