High risk. 7 critical or high findings in GDPR outside view, SSL/TLS and 1 other check.

Security score

34/100

Risk levelHigh

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

HABAU is a well-established Austrian construction company with over 110 years of experience, offering a broad range of construction services including high-rise construction, civil engineering, pipeline construction, and precast concrete solutions. It operates as part of the larger HABAU GROUP, which has a significant international presence and a large workforce. The website reflects a professional and content-rich digital presence targeting construction clients, partners, and job seekers. Technically, the site is built on WordPress with common performance and cookie management plugins, but suffers from slow load times and lacks a valid SSL certificate, which is a critical security concern. Privacy compliance is well addressed with a comprehensive privacy policy and cookie consent mechanism. Security posture is weak due to missing HTTPS and security headers, exposing the site to risks. Overall, the site is trustworthy and professional but urgently needs to address its SSL and security configuration to protect users and improve trust.

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

7 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

    • Critical

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

  2. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

  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 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
  • 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

HABAU holds a strong market position in Austria's construction sector as a top player and part of the HABAU GROUP. Its business model focuses on providing comprehensive construction services across multiple sectors including real estate, transportation, and energy infrastructure. The company leverages its long history and group affiliation to maintain competitive advantages. Revenue streams likely come from large-scale construction projects and public-private partnerships. The website supports recruitment efforts and brand positioning. Partnerships and related domains indicate a well-integrated corporate ecosystem. Growth indicators include international presence and diversified service offerings.

Security posture

The current security maturity level is low due to the absence of a valid SSL certificate and HTTPS support, which is a critical vulnerability that can lead to data interception and loss of user trust. No security headers are implemented, and advanced SSL features like HSTS and OCSP stapling are missing. There is no visible incident response or security policy on the website. GDPR compliance is addressed through privacy and cookie policies, but technical security gaps undermine overall protection. Immediate remediation of SSL and security headers is essential to reduce business risk and comply with best practices.

Recommendations

  1. Install and maintain a valid SSL/TLS certificate to enable HTTPS across the entire site.
  2. Configure and enable modern TLS protocols (TLS 1.2 or TLS 1.3) and disable insecure protocols.
  3. Implement HTTP security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Enable HTTP Strict Transport Security (HSTS) with includeSubDomains and preload options.
  5. Establish and publish a security policy and incident response contact information to enhance transparency and readiness.

Technical notes

Notes

The website is built on WordPress CMS using jQuery and performance optimization plugins like WP Rocket and Borlabs Cookie for consent management. The site uses modern frontend libraries such as Select2 and Tiny Slider for UI components. Despite a professional design and good mobile optimization, the site suffers from slow loading times (over 8 seconds) and lacks valid SSL, which severely impacts security and user trust. No advanced frameworks or hosting provider details are evident. SEO is well addressed with meta tags and Open Graph data. Accessibility is basic but present. Technical debt includes missing HTTPS and security headers, which should be prioritized for remediation.
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.
