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

ISMM & TESO s.r.o. is a Czech manufacturing company specializing in teraco products such as stairs, stair arms, tiles, and accessories, with a tradition spanning over 30 years. The company targets construction professionals and end customers seeking high-quality teraco solutions. Their market position is supported by strong references and membership in the ISMM group, indicating industry credibility. The website reflects a professional business with clear contact information and product offerings. Technically, the site uses standard web technologies including jQuery and lightbox scripts, hosted likely by Wedos, with moderate performance and basic mobile optimization. Security posture is adequate with HTTPS enabled and no visible vulnerabilities, though security headers and privacy compliance mechanisms like cookie consent are missing. The site uses Google Analytics for tracking without explicit cookie consent, indicating partial GDPR compliance. Overall, the website is trustworthy and professionally presented but could improve in privacy and security best practices.

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"

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 the manufacturing sector focused on teraco products, serving a niche market in the Czech Republic. Their business model combines product manufacturing with installation and maintenance services. The company leverages its 30-year history and industry certifications to maintain a competitive advantage. The website indicates a direct sales approach with online product listings and detailed references. The partnership with ISMM group enhances their market credibility. Growth potential lies in expanding online presence and improving digital marketing. Revenue streams likely include product sales and service contracts. The absence of social media links suggests limited digital marketing channels currently. Strategic partnerships and certifications are key strengths.

Security posture

The website demonstrates a basic to moderate security maturity level. HTTPS is properly implemented, ensuring encrypted communications. However, the absence of security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options reduces protection against common web attacks. No incident response or security policy information is provided, limiting transparency and readiness indicators. The use of Google Analytics without cookie consent indicates GDPR compliance gaps. No forms or input fields reduce attack surface but also limit user interaction. Overall, the security posture is adequate for a small manufacturing business website but requires enhancements to meet modern compliance and security standards.

Recommendations

  1. Implement a cookie consent banner and detailed cookie policy to improve GDPR compliance.
  2. Add security headers (CSP, X-Frame-Options, X-Content-Type-Options) to enhance protection against web vulnerabilities.
  3. Publish a security policy and incident response contact information to improve transparency and readiness.
  4. Improve mobile optimization and accessibility to enhance user experience across devices.
  5. Consider integrating social media channels and expanding digital marketing efforts to increase market reach.

Technical notes

Notes

The website is built using standard HTML, CSS, and JavaScript with libraries such as jQuery, Lightbox, and Splide.js for UI enhancements. The hosting and domain registration are managed by Wedos, a known Czech provider. The site uses HTTPS with a valid SSL certificate, ensuring secure connections. Performance is moderate with no major issues detected, but mobile optimization is basic and could be improved. SEO is basic with meta tags present but no advanced structured data like JSON-LD or Open Graph tags detected. No CMS or advanced frameworks are identified, indicating a custom or static site. The technical stack is stable but could benefit from modernization and enhanced accessibility features.
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.
