High risk. 8 critical or high findings in GDPR outside view, SSL/TLS and 1 other check.

Security score

32/100

Risk levelHigh

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

Christof Group is a large, family-owned industrial group specializing in critical process equipment manufacturing and plant engineering services, operating across Austria, Germany, and Slovenia. The company is positioned as a world leader in its sector with a strong portfolio of subsidiaries and a history of over 150 years in the industry. The website reflects a professional B2B business model targeting industrial clients in energy, petrochemical, and pharmaceutical sectors. Technically, the site is built on WordPress with modern SEO and multilingual capabilities but lacks HTTPS, which is a significant security shortfall. The security posture is weak due to the absence of SSL/TLS encryption and limited security headers, exposing the site to potential risks. Privacy compliance is addressed with a cookie consent mechanism and privacy policy, but incident response and security policies are missing. Overall, the site is functional and professional but requires urgent security improvements to protect user data and enhance 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

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

      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

The Christof Group operates a multi-company structure with 9 subsidiaries and 2,000 employees, serving complex apparatus engineering and plant services markets. Their competitive advantage lies in their extensive experience, technological leadership, and comprehensive service offerings including shutdowns, pipeline construction, and high-pressure equipment manufacturing. The business model focuses on B2B industrial clients with a global reach. The partnership with jchristof.com indicates a broader ecosystem for plant engineering and industrial services. The website supports multiple languages, indicating a focus on international markets. Growth indicators include a large project portfolio and diversified operations across several countries.

Security posture

The website currently lacks a valid SSL/TLS certificate, resulting in no HTTPS support, which is a critical vulnerability. Security headers are minimal, and no advanced security policies or incident response information is provided. The site uses modern JavaScript libraries and plugins but does not expose known vulnerable libraries. Privacy compliance is supported via Usercentrics CMP for cookie consent. The absence of HTTPS and HSTS significantly lowers the security score and exposes users to risks such as data interception. No security.txt or vulnerability disclosure policy is present, limiting transparency and incident handling readiness.

Recommendations

  1. Install and configure a valid SSL/TLS certificate to enable HTTPS across the entire site.
  2. Implement security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options.
  3. Enable HSTS with includeSubDomains and preload directives to enforce HTTPS.
  4. Publish a clear security policy and incident response contact information on the website.
  5. Add a vulnerability disclosure policy or security.txt file to improve transparency and trust.
Technical notes

Notes

The website is hosted on Cloudways with nginx server and uses WordPress CMS with plugins such as Yoast SEO, WPML, and SearchWP. The site is multilingual and optimized for SEO with proper meta tags and structured data (JSON-LD). JavaScript libraries include jQuery and Usercentrics CMP for cookie consent management. Performance metrics are not provided, but the site uses lazy loading for images and preconnect/preload hints for resources. The absence of HTTPS is a major technical risk. Accessibility and mobile optimization appear adequate but could be improved with more explicit ARIA roles and accessibility testing.
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.
