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 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 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

Mentorist occupies a niche in the education sector, focusing on personal and business development through book summaries and actionable steps. Its freemium business model includes free access with limits and paid Pro subscriptions for unlimited access. The company leverages social media channels for marketing and engagement. The platform's competitive advantage lies in combining summaries with actionable to-do lists, differentiating it from typical summary apps. The company appears to be small but focused, with clear branding and a consistent message. Payment processing is handled via Stripe, indicating secure transaction handling. The absence of explicit security policies or incident response contacts suggests room for maturity in security governance.

Security posture

The website enforces HTTPS and uses secure third-party services for analytics and marketing. Security headers are not explicitly visible in the HTML but may be configured at the server level. No vulnerabilities or exposed sensitive data were detected in the content. Cookie consent is implemented, supporting privacy compliance. However, the lack of a published security policy or incident response contact reduces transparency in security governance. Recommendations include adding security headers, publishing a security policy, and establishing a vulnerability disclosure process to enhance trust and compliance.

Recommendations

  1. Implement and publish a formal security policy and incident response contact information.
  2. Add and enforce security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Establish a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  4. Provide direct company contact emails or phone numbers for customer support and security inquiries.
  5. Regularly review and update privacy and cookie policies to maintain GDPR and other compliance standards.

Technical notes

Notes

The website uses a modern technology stack including Bootstrap 5 for responsive design, jQuery 3.6.0, Google Tag Manager, Google Analytics, and Facebook Pixel for analytics and marketing. The site is mobile-optimized with good navigation and content structure. Performance is moderate, with potential improvements in accessibility features. No CMS was detected, suggesting a custom or static site build. Hosting provider details are not disclosed. The site uses Stripe for payment processing, indicating secure handling of transactions. Overall, the technical implementation supports a professional user experience but could benefit from enhanced accessibility and security header configurations.
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.
