Security score

49/100

Risk levelHigh

0–100, higher is better. How it is calculated

Delta AG operates as a comprehensive service provider in the construction sector, offering architecture, general planning, construction management, green building, and IT services primarily in Austria. The company positions itself as a trusted partner for building projects, with a professional and consistent online presence targeting business clients in the real estate and construction industries. The website is built on WordPress with modern SEO and consent management tools, reflecting a mature digital infrastructure. Security posture is solid with HTTPS and cookie consent mechanisms, though some security headers and explicit policies could be improved. Overall, the site demonstrates good compliance with GDPR and marketing transparency, but lacks visible direct contact information and formal security policies. The domain registration data aligns well with the business identity, supporting legitimacy and trustworthiness.

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: SMB

      Port 445 (SMB) is publicly accessible - SMB - Windows file sharing, high risk

      What to do: Immediately restrict access to SMB 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
    • 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 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';…

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

Delta AG appears to be a medium-sized company focused on the Austrian construction market, providing end-to-end services from architecture to IT support. Their business model revolves around project management and consulting, targeting corporate and institutional clients. The use of Cookiebot and Google Analytics indicates a commitment to privacy compliance and data-driven marketing. The absence of explicit terms of service and incident response contacts suggests areas for maturity improvement. The company leverages partnerships with major platforms like Google and Meta for advertising and analytics, enhancing market reach. The website content and structured data reinforce their market positioning as a reliable and professional service provider.

Security posture

The website enforces HTTPS and uses a reputable cookie consent tool, which are positive security indicators. However, explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options are not evident in the HTML content, representing potential areas for enhancement. No vulnerabilities or exposed sensitive data were detected in the analyzed content. The lack of a published security policy or incident response contact limits transparency in security governance. Overall, the security posture is good but could benefit from formalized policies and additional technical controls.

Recommendations

  1. Implement and verify comprehensive security headers including CSP, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  2. Publish a clear security policy and incident response contact information to improve transparency and trust.
  3. Enhance accessibility features to improve compliance and user experience for all visitors.
  4. Add visible and verified contact information such as emails and phone numbers to facilitate user communication.
  5. Regularly audit and update all plugins and third-party scripts to minimize vulnerability risks.

Technical notes

Notes

The website is built on WordPress 6.8.2 with Yoast SEO and Cookiebot for consent management, indicating a modern and SEO-friendly platform. It uses jQuery 3.5.1 and Slider Revolution for interactive elements. Google Analytics and Google Tag Manager are integrated for analytics and marketing. The site shows moderate performance and good mobile optimization. Structured data in JSON-LD format is well implemented for SEO benefits. Hosting provider details are not explicit, but the site uses standard CDN and analytics services. Technical risks include potential outdated plugins and missing security headers, which should be addressed to maintain operational security and performance.
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.
