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

9 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

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

Proton Group's market positioning as a family-owned industrial conglomerate is supported by its portfolio of subsidiaries, each with dedicated domains and brand identities. The business model centers on industrial investments and sustainable growth, targeting industrial sector stakeholders and potential employees. The company leverages social media channels and maintains a newsletter for engagement. The presence of sustainability awards like the EcoVadis Gold Medal enhances trust and market credibility. The website's multilingual support (Swedish and English) indicates an international outlook. The absence of terms of service and formal security policies suggests areas for maturity improvement.

Security posture

The website enforces HTTPS and uses cookie consent tools to comply with GDPR. No security headers were explicitly detected in the HTML content, and no vulnerability disclosures or security.txt files are present. There is no published incident response or security contact information. No exposed sensitive data or vulnerable libraries were identified. The security score is good but could be improved by publishing formal security policies and incident response procedures. The site does not show signs of WAF blocking or security challenges, indicating stable accessibility.

Recommendations

  1. Publish a formal security policy and incident response plan on the website.
  2. Add a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  3. Include terms of service to clarify user and business obligations.
  4. Enhance accessibility features to improve compliance and user experience.
  5. Regularly audit and update security headers and monitor for vulnerable libraries.

Technical notes

Notes

The website is built on WordPress with modern front-end technologies including Alpine.js and uses Rank Math SEO for optimization. Google Tag Manager and Cookiebot are integrated for analytics and consent management. The site loads moderately fast with responsive design for mobile devices. There is no explicit hosting provider information detected. The technical implementation is solid with room for improvement in accessibility and security header implementation. The site architecture supports multiple subsidiaries and language versions, indicating a scalable infrastructure.
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.
