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

Franz Hasler AG is a well-established company based in Liechtenstein specializing in sustainable construction, solar energy solutions, and comprehensive construction management services. The company leverages over a century of tradition combined with ecological values to serve clients seeking environmentally conscious building solutions. Their business model focuses on acting as a general and total contractor, managing projects from planning through to completion, ensuring quality, timing, and cost control. The company maintains subsidiaries focused on solar energy and construction management, enhancing their service portfolio. Technically, the website is built on WordPress with standard web technologies and plugins. However, the site suffers from slow load times and lacks modern security configurations such as HTTPS, security headers, and cookie consent mechanisms. Mobile optimization and navigation are good, but performance and security are areas needing improvement. From a security perspective, the absence of a valid SSL certificate and HTTPS is a critical vulnerability, exposing users to potential data interception risks. The lack of security headers and no visible incident response or security policies further weaken the security posture. Privacy compliance is minimal, with no cookie consent or GDPR indicators present. Overall, while the business credibility and content quality are good, the technical and security shortcomings significantly impact the website's trustworthiness and user safety. Strategic improvements in security and privacy compliance are essential to enhance the company's digital maturity and protect its clients and reputation.

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

      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. 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: 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 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

  4. 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 · 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

Franz Hasler AG holds a strong regional market position in Liechtenstein as a specialist in sustainable building and energy solutions. Their competitive advantage lies in their long-standing tradition, ecological focus, and integrated service offerings covering wood construction, solar energy, and construction management. The business model is project-based, targeting clients who value sustainability and turnkey construction services. Revenue streams likely derive from construction projects, solar installations, and management contracts. The company ecosystem includes subsidiaries dedicated to solar and construction management, indicating a diversified but related service portfolio. Growth indicators include active news updates and a professional web presence, though digital marketing and analytics usage appear limited. Partnerships and social media presence support brand visibility but could be expanded for greater market reach.

Security posture

The current security maturity level of the website is low due to the absence of HTTPS and valid SSL certificates, which is a critical vulnerability. No security headers such as Content-Security-Policy or X-Frame-Options are implemented, increasing exposure to common web attacks. The lack of cookie consent and privacy compliance mechanisms indicates GDPR gaps. No incident response or vulnerability disclosure policies are visible, suggesting limited readiness for security incidents. While no known vulnerabilities or malware are detected, the weak security posture poses risks to user data and company reputation. The business impact of these vulnerabilities includes potential data breaches, loss of customer trust, and regulatory non-compliance. Enhancing security controls and compliance measures is imperative to mitigate these risks and foster a security-aware culture.

Recommendations

  1. Obtain and deploy a valid SSL/TLS certificate to enable HTTPS across the entire website.
  2. Implement essential security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Introduce a cookie consent banner and privacy compliance mechanisms to align with GDPR requirements.
  4. Develop and publish a security policy and incident response plan accessible to users.
  5. Enable OCSP stapling and support modern TLS protocols (TLS 1.2 or 1.3) with strong cipher suites.
  6. Add a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  7. Optimize website performance to reduce load times and improve user experience.

Technical notes

Notes

The website is built on WordPress CMS using standard web technologies including CSS3 and JavaScript with the Slick Slider plugin for interactive elements. Hosting is provided by Swizzonic, as indicated by DNS nameservers. The site has a slow load time (~19 seconds) and a large number of resources (90) contributing to performance issues. Mobile optimization is good, with responsive design and clear navigation. SEO is basic with meta tags present but no advanced structured data or Open Graph tags detected. Accessibility features are minimal but present. The lack of HTTPS and security headers represents a significant technical risk. Modernization opportunities include upgrading security protocols, improving performance, and enhancing privacy compliance. Technical debt is evident in the absence of SSL and slow resource loading, which could impact business operations and user trust.
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.
