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

7 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

    • 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

The website occupies a specialized market niche offering free screen testing and cleaning tools online. Its competitive advantage lies in ease of use, no downloads, and multi-device compatibility. Revenue likely derives from Google Adsense advertising. The target customers are individuals and professionals needing quick screen diagnostics or cleaning aids. The site supports multiple languages, indicating a global reach. Partnerships or subsidiaries are not evident. Growth indicators include comprehensive tool offerings and active analytics tracking. The business operates as a small entity focused on utility and user experience.

Security posture

The security maturity level is moderate to high. The site enforces HTTPS and implements key security headers, reducing common web vulnerabilities. No vulnerable libraries or exposed credentials were detected. However, the absence of a dedicated security policy, vulnerability disclosure, or incident response contact limits transparency and readiness. GDPR compliance is indicated via privacy and cookie policies with consent mechanisms. The security culture appears focused on best practices but could improve formal documentation and communication channels.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and frameworks.
  2. Implement and publicize a vulnerability disclosure policy or security.txt file.
  3. Provide clear incident response contact information such as security@ or abuse@ emails.
  4. Consider adopting recognized security frameworks like ISO 27001 or NIST for enhanced trust.
  5. Enhance contact information availability to improve business credibility and user trust.

Technical notes

Notes

The website uses a modern tech stack centered on the Astro framework, leveraging Cloudflare for DNS and hosting, ensuring robust performance and security. It integrates Google Fonts for typography and uses Microsoft Clarity and Plausible for analytics, balancing user privacy and insight. Google Adsense is used for monetization. The site is mobile-optimized with responsive design and accessibility features. SEO is well addressed with proper meta tags and structured data (JSON-LD). No CMS was detected, indicating a custom or static site approach. Technical risks are minimal, but continuous monitoring of third-party scripts and ad services is recommended to avoid supply chain vulnerabilities.
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.
