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

Potrubí Seidler s.r.o. is a small Czech company specializing in the installation of large-dimension piping systems including steam, hot water, gas, and water pipelines, as well as related construction and maintenance services. Founded in 2007 with roots dating back to 1995, the company serves industrial and construction clients primarily in the energy and manufacturing sectors. The website presents a clear overview of their services and company history but lacks modern digital maturity features such as privacy policies and updated technology stacks. Technically, the site uses older JavaScript libraries and lacks visible security headers or confirmed HTTPS enforcement, which poses security risks. The absence of WHOIS data reduces domain trustworthiness, although the site content and contact information appear legitimate. Overall, the security posture is weak, and compliance with GDPR is not evident. Strategic improvements in security, privacy compliance, and technology modernization are recommended to enhance trust and operational resilience.

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

10 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

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

  2. 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 operates in a niche B2B market focused on piping and construction services for industrial clients. Their competitive advantage lies in their long-standing experience and specialized service offerings including installation, welding, and project management. Revenue streams likely derive from contracts with industrial and municipal clients. The partnership with Logstor indicates access to quality piping products. The website's limited digital marketing and absence of analytics suggest a traditional business model with low digital engagement. Growth opportunities may exist through enhanced online presence and compliance with modern security and privacy standards.

Security posture

The current security posture is basic with notable weaknesses. The use of outdated jQuery 1.8.3 introduces potential vulnerabilities. No security headers or HTTPS enforcement details were found, increasing risk exposure. The lack of privacy and cookie policies indicates non-compliance with GDPR, which could lead to regulatory issues. No incident response or vulnerability disclosure information is provided, limiting transparency and preparedness. Overall, the security maturity is low, and immediate remediation is advised to protect business operations and customer data.

Recommendations

  1. Upgrade all JavaScript libraries to supported, secure versions to mitigate known vulnerabilities.
  2. Implement HTTPS site-wide with a valid SSL certificate and enforce secure connections.
  3. Add comprehensive privacy and cookie policies to comply with GDPR and inform users.
  4. Deploy standard security headers such as Content-Security-Policy, X-Frame-Options, and HSTS.
  5. Establish and publish incident response and vulnerability disclosure procedures to enhance trust.

Technical notes

Notes

The website uses legacy jQuery 1.8.3 and the jQuery Cycle2 plugin for slideshows, indicating outdated front-end technology. No modern frameworks or CMS platforms were detected. The site has basic mobile responsiveness and SEO meta tags but lacks advanced accessibility features. Hosting provider and SSL configuration details are not available. Performance is moderate with no evident optimization. The site structure is simple and functional but could benefit from modernization to improve security, performance, and user experience.
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.
