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"

  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

  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

Masteriyo targets WordPress users and online educators seeking a robust LMS solution. Its business model revolves around plugin sales and SaaS-like features integrated into WordPress. The company appears to be small-sized, founded in 2020, with a clear focus on education technology. Partnerships with payment processors like Lemon Squeezy and LMS Qeezy indicate a growing ecosystem. The presence of video tutorials and social media engagement supports customer education and marketing efforts. The business shows signs of steady growth and market positioning as a competitive LMS plugin provider.

Security posture

The website employs HTTPS with a valid SSL certificate and domain transfer protection, indicating a secure baseline. However, the absence of DNSSEC and security headers such as Content-Security-Policy or X-Frame-Options suggests room for improvement. No vulnerabilities or exposed sensitive data were detected in the HTML content. The site uses standard security practices but lacks published incident response or vulnerability disclosure information. Privacy compliance is minimal, with no visible GDPR-specific mechanisms or cookie consent banners. Overall, the security posture is good but could be enhanced by adopting additional best practices and transparency.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security.
  2. Publish comprehensive privacy and cookie policies with GDPR compliance details.
  3. Implement security headers like Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  4. Add a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  5. Provide clear incident response contact information for security issues.

Technical notes

Notes

The website is built on WordPress CMS with a modern tech stack including PHP, JavaScript, and jQuery. It uses Cloudflare for DNS management and NameCheap as the registrar. Performance is optimized with lazy loading scripts and preconnect hints. The site is mobile-optimized and accessible with good SEO metadata and structured data (JSON-LD). Some technical debt is noted in missing security headers and lack of explicit privacy/cookie policy pages. The infrastructure is solid but could benefit from enhanced security configurations and formalized 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.
