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

CLASIC CZ s.r.o. is a Czech manufacturing company specializing in industrial furnaces and related devices, with a well-established presence since 1998. Their website showcases a broad portfolio of furnace types and control systems, targeting industrial clients requiring specialized thermal equipment. The company appears to operate primarily in the manufacturing sector within the Czech Republic. Technically, the website is built using Nicepage CMS with standard web technologies such as HTML5, CSS3, JavaScript, and jQuery, and is hosted via a Czech hosting provider. The site is mobile-optimized and presents content clearly, though it lacks advanced SEO and accessibility features. Security posture is basic, with no evident security headers or published security policies, and no HTTPS status was determinable from the provided data. Privacy compliance is minimal, as no privacy or cookie policies are found. Overall, the website is functional and professional but would benefit from enhanced security and compliance measures.

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

11 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. 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.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  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"

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 manufacturing market, supplying a wide range of industrial furnaces and devices. Their business model is B2B, focusing on industrial clients needing specialized thermal processing equipment. The domain age and WHOIS data support a legitimate and stable business operation. The lack of published privacy and security policies may indicate a gap in compliance maturity. No evident partnerships or subsidiaries are identified from the website content. The company’s product range and control software offerings suggest a vertically integrated approach to furnace manufacturing and control solutions.

Security posture

The website currently exhibits a basic security posture. There is no evidence of HTTPS enforcement or security headers in the HTML content. No incident response contacts or security policies are published, which limits transparency and readiness for security incidents. The absence of privacy and cookie policies also indicates potential GDPR compliance gaps. No vulnerable libraries or exposed sensitive data were detected in the HTML content. The security score is moderate but should be improved by implementing HTTPS, security headers, and publishing relevant policies.

Recommendations

  1. Publish a comprehensive privacy policy and cookie policy to improve GDPR compliance.
  2. Implement HTTPS with strong SSL/TLS configuration and enforce secure connections.
  3. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Provide clear contact information for security incidents and incident response.
  5. Conduct a security audit to identify and remediate any potential vulnerabilities.

Technical notes

Notes

The website uses Nicepage CMS with jQuery and Google Fonts, indicating a modern but basic technology stack. Hosting is provided by Active24, a Czech hosting provider, consistent with the company’s location. The site is mobile-optimized and has a clear navigation structure. However, SEO and accessibility features are basic and could be enhanced. No analytics or tracking scripts are detected, which may be positive for privacy but limits marketing insights. Performance is moderate, with no major issues detected in the HTML content. Technical debt appears low but modernization opportunities exist, especially in security and 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.
