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

Rubena, s.r.o. is a Czech manufacturing company specializing in a broad range of rubber products including V-belts, air springs, flexible and inflatable rubber products, hockey pucks, technical molded rubber, rubber compounds, and mold production. The company operates multiple e-commerce platforms targeting industrial and commercial customers, indicating a diversified business model and a solid market position in the manufacturing sector. The website is professionally designed with clear navigation and consistent branding, supporting a positive user experience and trustworthiness. Technically, the website employs modern analytics tools such as Google Analytics and Google Tag Manager, alongside a comprehensive cookie consent management system via CookieScript. The site appears to be custom-built or uses a proprietary CMS platform by SHERWOOD Media s.r.o. Performance is moderate with good mobile optimization and basic accessibility features. However, security headers are not explicitly detected, suggesting room for improvement in security hardening. From a security perspective, the site enforces HTTPS and implements a detailed cookie consent mechanism aligned with GDPR requirements. No critical vulnerabilities or exposed sensitive data were identified in the HTML content. The absence of explicit incident response contacts or a security.txt file indicates an opportunity to enhance transparency and readiness for security incidents. Overall, the domain WHOIS data is unavailable or privacy protected, which is common for medium-sized enterprises but limits direct verification of domain registration details. The website’s content, social media presence, and compliance measures provide strong trust signals. Strategic recommendations include implementing security headers, publishing incident response information, and enhancing accessibility compliance to further strengthen the security posture and user trust.

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

5 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 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

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  3. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • High

      No DMARC record found

      DMARC provides email authentication and reporting

      What to do: Add DMARC record: "v=DMARC1; p=none; rua=mailto:dmarc@yourdomain.com"

  4. 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

  5. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security

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

Rubena operates in the manufacturing sector with a focus on rubber products serving industrial clients. The company leverages multiple e-commerce channels to distribute specialized products such as V-belts, tires, and service stock, indicating a hybrid B2B and B2C business model. The presence of detailed product categories and downloadable catalogs suggests a mature product portfolio. Social media engagement on Facebook and LinkedIn supports brand visibility and customer engagement. The partnership with SHERWOOD Media s.r.o. for website development reflects a professional digital presence. The lack of direct contact emails or phone numbers on the homepage suggests contact is centralized via dedicated pages, typical for corporate sites. Overall, Rubena appears well-positioned with diversified revenue streams and a clear industrial target audience.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and a robust cookie consent mechanism that categorizes cookies by necessity, performance, targeting, and functionality. The use of Google Analytics and Tag Manager is transparent and accompanied by detailed cookie declarations. However, the absence of explicit security headers such as Content Security Policy, HSTS, and X-Frame-Options reduces the overall security hardening. No visible vulnerabilities or exposed sensitive data were found in the HTML content. The lack of incident response contact information or a published security.txt file limits the site's preparedness for vulnerability reporting and incident management. Compliance with GDPR is evident through privacy and cookie policies. Enhancing security headers and incident response transparency would improve the security posture significantly.

Recommendations

  1. Implement standard security headers including Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), X-Frame-Options, and X-XSS-Protection to enhance protection against common web attacks.
  2. Publish a security.txt file and provide clear incident response contact information to facilitate vulnerability reporting and improve security transparency.
  3. Conduct regular audits of third-party scripts and libraries to ensure no vulnerable components are included.
  4. Improve website accessibility features to meet WCAG standards, enhancing usability for all users and compliance.
  5. Maintain and update privacy and cookie policies regularly to reflect evolving legal requirements and best practices.

Technical notes

Notes

The website uses a custom or proprietary CMS platform likely developed by SHERWOOD Media s.r.o., as indicated by meta author tags and cookie naming. It integrates Google Analytics and Google Tag Manager for analytics and marketing tracking. CookieScript is used for cookie consent management, providing granular control and detailed cookie declarations. The site loads multiple CSS stylesheets and JavaScript files asynchronously, supporting performance optimization. Mobile optimization is good with responsive design elements. However, no explicit hosting provider information is found. Performance is moderate, with potential improvements in loading speed and accessibility. The technical stack is modern but could benefit from enhanced security configurations and accessibility compliance.
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.
