Security report for neoperl.com

Neoperl GmbH · Manufacturing · Switzerland

Low risk. 3 critical or high findings in Security headers and SSL/TLS.

Security score

79/100

Risk levelLow

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

Neoperl GmbH is a Swiss-based manufacturer specializing in water flow control products such as aerators, flow regulators, and check valves. The company positions itself as a global supplier focused on water conservation and quality, targeting OEMs and manufacturers in the water industry. The website is professionally designed using modern web technologies including React and Next.js, offering multilingual support and a product finder tool. Privacy compliance is well addressed with a comprehensive privacy policy and cookie consent mechanism. However, the absence of WHOIS registration data and explicit security headers slightly reduce trustworthiness. Overall, the site demonstrates a mature digital presence with good security posture but could improve transparency in incident response and domain registration details.

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

3 findings rated critical or high. Fix these first.

  1. 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 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';…

  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.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

Neoperl operates in the manufacturing sector with a focus on water-related products, serving a global market. Their business model revolves around supplying specialized components to OEMs and manufacturers, emphasizing water conservation. The company maintains a strong online presence with multilingual support and social media engagement across major platforms. The lack of WHOIS data may indicate privacy protection or registration issues, but the structured data and contact information support legitimacy. No direct evidence of partnerships or subsidiaries was found in the content. The website's content and navigation suggest a well-established brand with consistent messaging and trust signals.

Security posture

The website enforces HTTPS and employs a cookie consent mechanism compliant with GDPR. However, no explicit security headers such as Content Security Policy or HSTS were detected, which are recommended for enhanced security. There is no published security policy or incident response contact information, and no security.txt file was found. Forms on the site appear standard without exposed sensitive data. The overall security posture is good but could be strengthened by adding security headers and formalizing vulnerability disclosure and incident response processes.

Recommendations

  1. Implement and publish a security.txt file to facilitate vulnerability reporting.
  2. Add standard security headers including CSP, HSTS, X-Frame-Options, and X-Content-Type-Options.
  3. Publish an explicit security policy and incident response contact information on the website.
  4. Verify and update WHOIS domain registration details to improve transparency and trust.
  5. Enhance accessibility features to meet higher standards and improve user experience.

Notes

The website is built on a modern React and Next.js framework, indicating a contemporary and maintainable tech stack. It uses SVG graphics and embedded video for rich media content. Cookie consent is managed via consentmanager.net scripts. The site appears mobile-optimized with good SEO practices including meta tags and structured data.

Overall, the technical implementation supports a professional and user-friendly experience with room for security and performance enhancements.
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.
