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

8 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 Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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

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

SuddenFix's market positioning as a professional, transparent, and customer-centric mobile repair service provider is reinforced by its extensive service coverage and partnerships with major technology and service companies. The O2O business model leverages online ordering with rapid on-site repair, appealing to busy consumers and enterprises. Revenue streams likely include repair services, device recycling, and value-added services like memory upgrades. The company demonstrates growth through customer volume and enterprise clients, supported by a strong digital presence and customer testimonials. The partnership ecosystem includes telecom, technology, and real estate companies, enhancing service reach and credibility.

Security posture

The website demonstrates a moderate to strong security posture with HTTPS enforced and secure form handling via SMS verification codes. However, the absence of explicit security headers such as Content Security Policy (CSP), HSTS, and X-Frame-Options reduces defense-in-depth. No public security policy or incident response contacts are provided, which limits transparency and preparedness perception. No vulnerabilities or exposed sensitive data were detected in the HTML content. The site would benefit from implementing a vulnerability disclosure policy and security.txt to enhance security culture and user trust.

Recommendations

  1. Implement and configure HTTP security headers including CSP, HSTS, and X-Frame-Options to mitigate common web attacks.
  2. Add a visible cookie consent banner and detailed cookie policy to comply with privacy regulations and improve user trust.
  3. Publish a dedicated security policy and incident response contact information to enhance transparency and preparedness.
  4. Consider establishing a vulnerability disclosure program and hosting a security.txt file to encourage responsible reporting.
  5. Regularly audit third-party scripts and dependencies to ensure no vulnerable libraries are included and maintain secure form handling.

  5. Use of multiple third-party scripts for analytics and user interaction.

Technical notes

Notes

The website uses a modern front-end technology stack including Vue.js for reactive components, Swiper.js for interactive carousels, and QRCode.js for dynamic QR code generation. The site is optimized for both desktop and mobile users, with automatic redirection to a mobile subdomain. Performance is moderate with asynchronous loading of analytics and tracking scripts. SEO is supported by proper meta tags and structured navigation. However, accessibility features are basic and could be improved. The hosting provider is not explicitly identified from the HTML content. The site uses multiple third-party analytics and marketing tools primarily from Baidu, indicating a focus on the Chinese market. Overall, the technical implementation supports a professional user experience but could benefit from enhanced accessibility and security hardening.
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.
