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

Prentner engineering & consulting is a small German-based engineering consultancy specializing in product development, design, FEM/MKS calculations, tooling technology, automation, assembly technology, and project management services. The company targets businesses requiring specialized engineering and consulting support in manufacturing and product innovation. Their website is built on WordPress with common plugins and provides content primarily in German with English alternatives. The site includes a cookie consent mechanism and a privacy policy, demonstrating GDPR compliance awareness. However, the absence of HTTPS is a critical security shortfall that undermines user trust and data protection. Technically, the website uses PHP 7.2.34 on an nginx server hosted by tele.net. The site employs popular WordPress plugins such as WPBakery Page Builder, LayerSlider, Contact Form 7, and Complianz GDPR. Performance data is missing or indicates slow loading, and SEO and accessibility optimizations are basic. Mobile optimization is good, and navigation is clear and professional. From a security perspective, the lack of SSL/TLS encryption is the most significant vulnerability, exposing users to potential data interception. No advanced security headers or incident response policies are found. Cookie consent is implemented properly, but no explicit security or incident response contacts are provided. WHOIS data aligns well with the website's business claims, indicating legitimacy. Overall, the website is functional and professional in content and design but requires urgent security improvements, especially enabling HTTPS and enhancing security headers. Privacy compliance is adequate, but business credibility could be improved by adding direct contact information and certifications.

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. 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"

    • 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';…

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 company operates in the manufacturing sector, providing essential engineering consulting services focused on product development and manufacturing process optimization. Their business model is service-oriented, targeting industrial clients needing expertise in development processes, FEM/MKS calculations, tooling, automation, and project management. The website positions the company as a niche player with specialized knowledge and experience. The absence of visible contact emails or phone numbers on the homepage suggests a controlled communication approach, likely directing inquiries through contact forms. The company maintains a GDPR-compliant cookie consent mechanism, indicating awareness of European data protection regulations. No partnerships or subsidiaries are evident from the website or WHOIS data. The business appears stable but small, with no indications of parent companies or subsidiaries.

Security posture

The security posture of the website is weak due to the absence of HTTPS, which is a critical vulnerability exposing all data transmissions to interception and manipulation. No security headers such as Content-Security-Policy, X-Frame-Options, or X-XSS-Protection are present, increasing the risk of cross-site scripting and clickjacking attacks. The server runs an outdated PHP version (7.2.34), which may no longer receive security updates, further increasing risk. Cookie consent is implemented, supporting privacy compliance, but no incident response or security policies are published. No known vulnerable libraries or malware indicators are detected. The lack of OCSP stapling and session resumption reduces TLS performance and security robustness. Overall, the site requires immediate security upgrades to protect user data and improve trustworthiness.

Recommendations

  1. Implement a valid SSL/TLS certificate and enable HTTPS site-wide to secure data transmission.
  2. Add security headers including Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to mitigate common web attacks.
  3. Upgrade PHP to a supported and secure version to reduce vulnerability exposure.
  4. Publish explicit security and incident response policies, including contact channels for security issues.
  5. Enhance website performance and SEO by optimizing resources and metadata.
Technical notes

Notes

The website is built on WordPress CMS using PHP 7.2.34 and nginx web server hosted by tele.net. It uses popular plugins such as WPBakery Page Builder for layout, LayerSlider for image sliders, Contact Form 7 for forms, and Complianz GDPR for cookie consent management. The site is mobile responsive with good navigation clarity. However, performance metrics are missing or indicate slow loading, possibly due to unoptimized resources or server configuration. The absence of HTTPS and modern TLS protocols is a critical technical deficiency. No advanced accessibility features are detected beyond basic responsive design. SEO optimization is basic with canonical and hreflang tags present but no Open Graph or JSON-LD structured data found. Overall, the technical infrastructure is functional but outdated and insecure.
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.
