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

10 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

  2. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  3. 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';…

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 · found on this site
  • 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

ZUK operates in the competitive digital marketing and web design sector, targeting small to medium businesses primarily in Spain. Their service portfolio includes web design, e-commerce solutions, SEO, SEM, and growth partnership, indicating a comprehensive digital service offering. The presence of a portfolio and blog suggests active client engagement and content marketing efforts. The agency uses modern marketing and analytics tools, including Facebook Pixel and Microsoft Clarity, to optimize campaigns and user experience. Their business model is service-based, relying on client projects and digital transformation initiatives. The lack of visible certifications or security policies suggests room for enhanced trust-building measures.

Security posture

The website employs HTTPS with a valid SSL certificate and integrates Google reCAPTCHA to protect forms from spam and abuse. Cookie consent is managed via Complianz with opt-in mechanisms, supporting GDPR compliance. However, the absence of explicit security headers like Content-Security-Policy or X-Frame-Options reduces the overall security hardening. No vulnerabilities or exposed sensitive data were detected in the HTML content. The WHOIS data is restricted, limiting domain trust verification. Incident response and vulnerability disclosure mechanisms are not publicly documented, which could be improved to enhance security transparency.

Recommendations

  1. Implement HTTP security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen security posture.
  2. Publish a dedicated security policy and incident response page to improve transparency and preparedness.
  3. Add a security.txt file to facilitate vulnerability reporting and responsible disclosure.
  4. Regularly audit and update WordPress plugins and themes to mitigate potential vulnerabilities.
  5. Enhance accessibility features and conduct periodic SEO audits to maintain and improve website performance.

Technical notes

Notes

The website is built on WordPress using Elementor as the primary page builder, supported by plugins like Yoast SEO, Contact Form 7, and Complianz for GDPR compliance. It integrates Google Analytics, Microsoft Clarity, and Facebook Pixel for analytics and marketing. The site is mobile-optimized with responsive design and uses modern web fonts and image optimization techniques. Performance is moderate, with potential improvements in caching and asset loading. The technical stack is standard for a professional digital agency, balancing ease of content management with marketing capabilities. Hosting provider details are not explicitly identified from the HTML content.
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.
