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

Fronius International GmbH is a well-established Austrian company specializing in welding technology, solar energy solutions, and battery charging technology. With a global footprint of 38 sites worldwide, the company serves industrial clients and partners with a focus on innovation and sustainability. The website reflects a professional and comprehensive digital presence, targeting a broad audience including customers, partners, and job seekers. Technically, the site uses modern web technologies such as Sitecore CMS, jQuery, and Google Tag Manager, and is mobile-optimized with good SEO practices. However, the security posture is weakened by the absence of a valid SSL certificate and disabled modern TLS protocols, which poses a significant risk to user trust and data security. Privacy compliance is strong, with clear privacy and cookie policies and GDPR adherence. Overall, the website is trustworthy and professional but requires urgent improvements in SSL/TLS configuration to enhance security and user confidence.

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

5 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

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, LinkedIn, YouTube, Google APIs

      What to do: Document all third-party data sharing in your privacy policy

  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

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

Fronius operates in the energy and manufacturing sectors with a diversified business model encompassing welding, solar energy, and battery charging technologies. The company maintains a strong international presence with subsidiaries and direct sales channels. Its market position is solid, supported by decades of innovation and a commitment to sustainability. The website content and structure indicate a mature business with clear branding, comprehensive service offerings, and active engagement through social media and career opportunities. The company leverages strategic partnerships and maintains transparency through codes of conduct and whistleblower channels, reinforcing its credibility and compliance culture.

Security posture

The website demonstrates good security practices in HTTP headers, including strict content security policies, frame options, and permissions policies. However, the lack of a valid SSL certificate and disabled TLS protocols critically undermine the security posture, exposing users to potential interception and trust issues. No incident response or security policy pages were found, indicating a possible gap in transparency around security governance. The use of Google reCAPTCHA and secure cookie flags are positive indicators. Immediate remediation of SSL/TLS issues is essential to align with best practices and regulatory requirements.

Recommendations

  1. Obtain and deploy a valid SSL/TLS certificate to enable HTTPS across the site.
  2. Enable and configure modern TLS protocols (TLS 1.2 and TLS 1.3) and disable deprecated protocols.
  3. Implement OCSP stapling and session resumption to improve security and performance.
  4. Publish a dedicated security policy and incident response information to enhance transparency.
  5. Continue maintaining and updating privacy and cookie policies to ensure ongoing GDPR compliance.

Technical notes

Notes

The website is built on the Sitecore CMS platform, utilizing jQuery and jQuery UI libraries, Google Tag Manager for analytics and marketing, and Google reCAPTCHA for bot protection. The site is well-structured with responsive design and accessibility considerations. Performance data was not available, but the use of modern image formats and preloading fonts suggests optimization efforts. Hosting appears to be managed via Austrian DNS providers. The absence of SSL/TLS is a critical technical deficiency. Overall, the technical infrastructure is modern but requires security upgrades to meet current standards.
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.
