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

The website 'Revize tlakových zařízení ve Zlíně a okolí' represents a small, specialized service provider focused on inspection, certification, and training related to pressure equipment safety in the Zlín region of the Czech Republic. The business offers a comprehensive range of services including revisions of pressure vessels, boilers, low-pressure boiler inspections, and operator training. The site is professionally designed with clear navigation and good mobile optimization, leveraging the AMP framework for fast performance. Structured data is implemented to enhance search visibility and provide detailed business information. Technically, the website uses modern AMP technologies and integrates Google Analytics for minimal user tracking. The site is served over HTTPS with good SSL configuration, though explicit security headers are not detected. There are no forms collecting sensitive data, reducing exposure risks. However, the absence of a cookie consent mechanism and explicit privacy policy pages (beyond a GDPR PDF) indicates room for improvement in privacy compliance. Security posture is generally good with no visible vulnerabilities or exposed sensitive data. The lack of WHOIS data for the domain is a notable concern, reducing trustworthiness from a domain registration perspective. Despite this, the presence of certifications and clear contact information supports the legitimacy of the business. Overall, the website is safe, professional, and well-suited for its target audience, but would benefit from enhanced security headers and privacy 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

9 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

      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 business operates in the energy sector, specifically focusing on pressure equipment safety and compliance services. It targets owners and operators of pressure vessels and boilers in the Zlín region, offering legally mandated inspections and operator training. The business model is service-oriented, relying on certifications and regulatory compliance to establish trust. The website links to partner sites offering complementary services, indicating a collaborative ecosystem. Revenue streams likely derive from inspection fees, training sessions, and consulting. The company appears small but specialized, with a strong local market presence. The lack of WHOIS data is a potential risk factor but does not detract from the operational legitimacy indicated by certifications and contact details.

Security posture

The website demonstrates a moderate to good security maturity level. HTTPS is enforced, and no sensitive data is exposed in the HTML. The use of AMP reduces attack surface by limiting custom scripts. However, the absence of key security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options is a gap. No incident response or security policy information is published, and no vulnerability disclosure or security.txt files are found. Privacy compliance is partial, with GDPR information provided but no cookie consent mechanism. The domain's missing WHOIS data reduces trust and could indicate registration issues. Overall, the site is secure for visitors but could improve transparency and header security.

Recommendations

  1. Implement and enforce security headers including CSP, HSTS, and X-Frame-Options to enhance protection against common web attacks.
  2. Add a visible cookie policy and consent mechanism to comply fully with privacy regulations and improve user trust.
  3. Publish a dedicated privacy policy page with clear GDPR compliance statements and data retention policies.
  4. Provide security policy and incident response contact information to improve transparency and readiness.
  5. Verify and update domain WHOIS registration to ensure public availability of registrant information and enhance domain trustworthiness.

Technical notes

Notes

The website is built using the AMP framework, ensuring fast loading times and excellent mobile optimization. It uses standard AMP components for animations, image lightboxes, and analytics integration. Google Analytics is implemented with minimal tracking. The site uses semantic HTML and structured data (JSON-LD) to improve SEO and provide rich business information. No CMS or hosting provider is explicitly identified. Performance is fast due to AMP and minimal external dependencies. Accessibility is good with clear navigation and readable fonts. However, the site lacks explicit security headers and cookie consent mechanisms. The WHOIS data is missing, which is unusual and should be investigated. Overall, the technical implementation is modern and efficient but could benefit from enhanced security and privacy 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.
