Risk levelHigh

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

starlim sterner is a well-established Austrian manufacturing company specializing in liquid silicone injection molding, holding a world market leader position. Their website reflects a mature business with comprehensive service offerings including product development, tooling, and cleanroom production. Technically, the site is built on WordPress with modern SEO and cookie consent implementations, but lacks a valid SSL certificate, which is a critical security gap. The security posture is basic with no advanced protections like DNSSEC or security headers. Privacy compliance is strong with GDPR-aligned policies and cookie management. Overall, the business presents a professional image with moderate website performance and good user experience, but must urgently address HTTPS and security hardening to improve trust and security.

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

7 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';…

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 company targets industrial sectors such as Industry, Life Science, and Mobility, offering specialized silicone molding services. Their market position as a world leader is supported by decades of experience and certifications. The website's content and navigation support a B2B audience with detailed service descriptions and career opportunities. The presence of a dedicated career subdomain indicates organizational growth focus. Marketing and analytics tools are used responsibly with user consent. The domain age and WHOIS data align well with the company's claims, enhancing credibility.

Security posture

The current security maturity is low due to the absence of a valid SSL certificate and lack of security headers. While cookie consent and privacy policies are well implemented, the missing HTTPS exposes users to risks such as data interception. No incident response or security policy pages were found, indicating potential gaps in security governance. DNSSEC and domain protection mechanisms are not enabled, increasing risk of domain spoofing or hijacking. The site uses third-party scripts for marketing and analytics, which are controlled via consent mechanisms, reducing privacy risks. Immediate remediation of SSL and security headers is recommended.

Recommendations

  1. Obtain and deploy a valid SSL/TLS certificate to enable HTTPS across the entire site.
  2. Implement security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Enable DNSSEC and configure CAA records to protect domain integrity.
  4. Develop and publish a formal security policy and incident response plan accessible on the website.
  5. Regularly audit and update third-party plugins and scripts to mitigate vulnerabilities.
Technical notes

Notes

The website uses a WordPress CMS with Avia Framework and multiple plugins including Yoast SEO, Borlabs Cookie for consent management, and Thrive Leads. The site is moderately performant with a load time of approximately 6.9 seconds and 36 resources loaded. Mobile optimization and accessibility features are good, supported by ARIA roles and accessibility toolbar. SEO is enhanced by proper meta tags, Open Graph, and JSON-LD structured data. However, the lack of HTTPS and security headers represents technical debt and security risk. Hosting provider details are not explicitly identified but IP addresses suggest European hosting. The site uses multiple external domains for social media, analytics, and marketing pixels with user consent.
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.
