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

5 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

Asteco operates primarily in the real estate sector, targeting property owners, residents, and investors in the UAE market. Its business model centers on integrated real estate services including property and community management, brokerage, and advisory. The company benefits from a strong legacy and affiliation with Aldar Properties, enhancing its market credibility. Revenue streams likely derive from management fees, brokerage commissions, and advisory services. The company maintains a professional online presence with clear service offerings and customer engagement channels. Growth indicators include a broad portfolio and digital engagement. Partnerships with Aldar and use of advanced digital marketing tools indicate a strategic approach to market positioning and customer acquisition.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, comprehensive security headers, and use of Google reCAPTCHA to protect forms. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of a publicly available security policy or incident response contact reduces transparency and may impact incident handling readiness. There is no evidence of a vulnerability disclosure program or security.txt file. Compliance with GDPR is indicated by the presence of privacy and cookie policies with consent mechanisms. Overall, the security maturity is good but could be improved by publishing explicit security governance documents and incident response contacts.

Recommendations

  1. Publish a dedicated security policy page detailing security practices and compliance.
  2. Implement and publicize a vulnerability disclosure program or security.txt file.
  3. Provide clear incident response contact information, including security and abuse emails.
  4. Enhance transparency by including data retention policies and detailed privacy compliance statements.
  5. Regularly audit and update third-party scripts and tracking tools to minimize privacy risks.

Technical notes

Notes

The website is built using modern web technologies including React with Next.js framework and Material-UI for styling, ensuring responsive and accessible design. Hosting appears to leverage Akamai CDN for performance and security. Integration with Google Tag Manager, Facebook Pixel, LinkedIn Insight Tag, and Genesys Messenger indicates advanced marketing and customer engagement capabilities. Performance is optimized with preloading of critical assets and asynchronous loading of scripts. Accessibility and SEO best practices are observed with proper meta tags and semantic HTML. Technical risks are minimal, but continuous monitoring of third-party dependencies is recommended to avoid 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.
