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

STRABAG AG is Austria's largest construction company and a market leader in the construction industry, offering a wide range of services including building construction, civil engineering, and specialized trades. The company emphasizes expertise, innovation, and regional presence to deliver tailored construction solutions. Their website reflects a mature digital presence with professional design, clear navigation, and comprehensive content targeting clients, partners, and job seekers. Technically, the website uses modern JavaScript libraries such as jQuery and Matomo for analytics, alongside OneTrust for cookie consent management, indicating a commitment to privacy compliance. The site is mobile-optimized and SEO-friendly, though some accessibility features could be enhanced. Security-wise, HTTPS is used, and cookie consent is implemented; however, explicit security headers and incident response information are not evident, suggesting room for improvement. Overall, the website demonstrates a strong security posture with no visible vulnerabilities or suspicious content. The lack of WHOIS data due to privacy protection is common for large enterprises and does not detract from the site's legitimacy. The company maintains active social media channels and partner sites, reinforcing trust and transparency. Strategically, STRABAG AG should focus on publishing explicit security policies, enhancing accessibility, and implementing security headers to further strengthen their security posture and compliance. These steps will improve user trust and reduce potential risks associated with web vulnerabilities.

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. 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

    • 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

  2. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  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 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
  • 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

STRABAG AG holds a dominant position in Austria's construction market, leveraging its extensive expertise and innovation capabilities. The company operates a diversified business model covering multiple construction sectors, supported by subsidiaries like Böhm BiB GmbH. Their digital ecosystem includes dedicated career portals, sustainability initiatives, and supplier platforms, indicating a comprehensive partnership and growth strategy. STRABAG's strong brand consistency and professional online presence support its market leadership and appeal to a broad audience including clients, suppliers, and prospective employees. The company's focus on climate neutrality by 2040 highlights strategic foresight and commitment to sustainability, which may enhance competitive advantage and stakeholder trust.

Security posture

The website exhibits a moderate to strong security maturity level with HTTPS enforced and cookie consent mechanisms in place, reflecting GDPR compliance. The use of Matomo analytics suggests privacy-conscious data collection. However, the absence of visible security headers (e.g., CSP, HSTS) and lack of published incident response or vulnerability disclosure policies indicate gaps in security transparency and readiness. No exposed sensitive data or vulnerable libraries were detected in the HTML content. The site would benefit from publishing a security.txt file and explicit security policies to improve incident response capabilities and stakeholder confidence. Overall, the security posture is adequate for a corporate website but can be enhanced to meet best practices.

Recommendations

  1. Implement and enforce security headers such as Content-Security-Policy, Strict-Transport-Security, and X-Frame-Options.
  2. Publish a dedicated security policy and incident response contact information on the website.
  3. Create and maintain a vulnerability disclosure program or security.txt file to facilitate responsible reporting.
  4. Enhance website accessibility features to improve compliance with standards and user experience.
  5. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built on a modern JavaScript stack including jQuery 3.3.1 and Matomo for analytics, with OneTrust managing cookie consent, indicating a mature approach to privacy and user tracking. The use of Splide.js for sliders enhances user experience. The CMS appears custom or proprietary, as no common CMS signatures were detected. Performance is moderate with good mobile optimization and SEO practices. Accessibility is basic and could be improved. Hosting provider details are not evident from the HTML. Overall, the technical infrastructure supports a professional and scalable corporate website but could benefit from enhanced security configurations and accessibility improvements.
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.
