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

9 findings rated critical or high. Fix these first.

  1. 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: MSSQL

      Port 1433 (MSSQL) is publicly accessible - MSSQL - Database server

      What to do: Immediately restrict access to MSSQL 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

  2. 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';…

  3. 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

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

Ardanuy Ingeniería holds a strong position in the engineering consultancy market, particularly in transportation and energy infrastructure. Their competitive advantage lies in their multidisciplinary expertise and international project portfolio. Revenue streams are primarily from consulting, project design, and construction management services. The target customers are public and private sector clients requiring engineering solutions for large infrastructure projects. Growth indicators include ongoing international projects and investment in R&D. The company maintains a professional online presence and leverages social media for brand visibility. No direct partnerships or subsidiaries were identified from the website content.

Security posture

The security posture is moderate with HTTPS enforced and cookie consent implemented, indicating awareness of privacy regulations. However, the absence of DNSSEC and security headers reduces the overall security maturity. No incident response or vulnerability disclosure policies are published, which could hinder rapid response to security events. The use of third-party analytics and tracking tools introduces privacy considerations that should be managed carefully. No exposed credentials or critical vulnerabilities were found, but improvements in security best practices are recommended to align with industry standards and compliance frameworks.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Implement standard security headers such as Content Security Policy (CSP), Strict-Transport-Security (HSTS), X-Frame-Options, and X-Content-Type-Options.
  3. Publish a dedicated security policy and incident response contact information to improve transparency and readiness.
  4. Expand privacy policy details to explicitly address GDPR compliance and data retention practices.
  5. Conduct regular security audits of third-party scripts and dependencies to mitigate vulnerabilities.

Technical notes

Notes

The website uses a mature technology stack with Bootstrap and jQuery for responsive design and interactivity. The presence of multiple plugins (Owl Carousel, Easy Responsive Tabs, Pushy, Scrolla, Isotope, Magnific Popup, iCheck, YTPlayer) indicates a feature-rich user interface. Hosting is managed by Nominalia Internet SL, a reputable provider. Performance is moderate, with some potential for optimization due to multiple external scripts. The site is mobile-optimized but accessibility features are basic. SEO is supported by meta viewport tags and structured navigation but lacks advanced SEO metadata such as Open Graph or JSON-LD structured data. The use of ASP.NET suggests a robust backend platform. Overall, the technical implementation supports business needs but could benefit from modernization and performance tuning.
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.
