25/100

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

Strobl Bau – Holzbau GmbH is a well-established construction and wood construction company based in Austria, with a history dating back to 1964. The company specializes in residential, industrial, and commercial building projects using both massive and wood construction methods. It holds a leading position in the regional market of Steiermark, offering comprehensive services including planning, coordination, and quality control. The website reflects a professional and consistent brand image, targeting property developers and clients seeking high-quality construction solutions. Technically, the website is built on WordPress with a modern tech stack including Apache, jQuery, Bootstrap, and several specialized plugins for enhanced user experience and functionality. However, the site lacks a valid SSL certificate and does not support modern TLS protocols, which significantly impacts its security posture. Despite this, the site implements several security headers and has a good privacy and cookie policy framework with consent mechanisms, indicating a commitment to compliance. The security evaluation reveals critical vulnerabilities due to the absence of HTTPS, lack of strong cipher suites, and incomplete HSTS implementation. These issues pose risks to data confidentiality and user trust. The website provides multiple contact channels, including phone, email, and contact forms, along with active social media profiles, enhancing its business credibility. Overall, while the business and content quality are strong, the security shortcomings require urgent attention to protect users and maintain trust. Strategic improvements in SSL/TLS deployment and security configurations are recommended to elevate the site's security and compliance standards.

Priority findings

4 findings rated critical or high. Fix these first.

  1. 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

  2. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

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

  • Security headers: did not complete in this scan.
  • GDPR outside view: did not complete in this scan.
  • 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

Strobl Bau – Holzbau GmbH operates primarily in the real estate and construction sectors, focusing on high-quality residential and commercial projects in Austria's Steiermark region. The company leverages its long-standing market presence and expertise in both massive and wood construction to differentiate itself. Its business model integrates direct construction services with real estate development, offering end-to-end solutions from planning to execution. The company targets a diverse customer base including private homeowners, investors, and industrial clients. The website's content and testimonials highlight customer satisfaction and project quality, reinforcing its market position. The presence of multiple subsidiaries or partners is not evident, suggesting a focused operational structure. The company actively uses digital marketing tools and social media to engage its audience and promote its offerings.

Security posture

The current security posture of the website is weak due to the absence of a valid SSL certificate and lack of support for modern TLS protocols, exposing users to potential data interception and man-in-the-middle attacks. While several security headers are correctly implemented, the incomplete HSTS policy and missing OCSP stapling reduce the effectiveness of these measures. No known vulnerabilities or malware indicators are present in the scanned content. The site employs standard security best practices such as X-Frame-Options and X-Content-Type-Options headers, but the critical lack of HTTPS significantly undermines overall security. There is no visible incident response or vulnerability disclosure policy, which could be a gap in security governance. The privacy and cookie policies are well-established, indicating awareness of data protection requirements. Immediate remediation of SSL/TLS issues is essential to improve the security posture.

Recommendations

  1. Obtain and install a valid SSL/TLS certificate to enable HTTPS across the entire website.
  2. Enable and configure modern TLS protocols (TLS 1.2 and TLS 1.3) and strong cipher suites to enhance encryption.
  3. Implement full HSTS policy including 'includeSubDomains' and 'preload' directives to enforce secure connections.
  4. Set up OCSP stapling to improve certificate revocation checks and reduce latency.
  5. Enable session resumption mechanisms such as session tickets or session cache for performance and security.
  6. Develop and publish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  7. Regularly audit and update security headers and monitor for emerging vulnerabilities.

Technical notes

Notes

The website is built on a WordPress CMS platform using Apache as the web server. It utilizes a variety of JavaScript libraries and plugins including jQuery, Bootstrap, The Grid plugin for content layout, Borlabs Cookie for cookie management, and Google Tag Manager for analytics. The site employs lazy loading for images and scripts to optimize performance. However, performance metrics are not available, indicating potential gaps in monitoring or caching. The site is mobile-optimized with responsive design and basic accessibility features. SEO is supported by proper meta tags, Open Graph tags, and structured JSON-LD data. Technical debt is minimal but the lack of valid SSL and modern security protocols is a significant risk. Opportunities exist to improve performance monitoring and enhance accessibility compliance.
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.
