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

The website smartteplomery.cz represents a small technology business focused on providing smart thermometers and meteorological stations with remote administration capabilities. The business appears to be newly established in 2024, targeting consumers and small businesses interested in temperature monitoring solutions. The website offers an e-shop and user account management features, emphasizing data visualization and remote device control. Technically, the website is built with standard HTML, CSS, and JavaScript without reliance on major frameworks or CMS platforms. Hosting is provided by WEDOS, a Czech hosting provider. The site demonstrates good mobile optimization and user experience with a clean, consistent design. However, SEO and accessibility features are basic, and no advanced analytics or marketing tools are detected. From a security perspective, the site uses HTTPS (assumed from domain and modern standards, though not explicitly confirmed in the HTML). There is a lack of security headers and no visible privacy or cookie policies, which impacts GDPR compliance. No contact information or incident response channels are provided, limiting transparency and trust. No vulnerabilities or exposed sensitive data were detected in the provided content. Overall, the website is functional and professional but would benefit from enhanced privacy compliance, security hardening, and clearer business contact information to improve trust and regulatory adherence.

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

  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"

    • 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 technology sector providing smart temperature monitoring devices with remote management. The business model combines product sales via an e-shop with cloud-based account management services. The target market likely includes tech-savvy consumers and small enterprises requiring environmental monitoring. The website's recent domain registration aligns with a startup or new product launch. The absence of extensive marketing or analytics tools suggests a focus on organic growth or direct sales. No partnerships or subsidiaries are evident. The business maintains consistent branding and clear product messaging, positioning itself as a specialized provider in the Czech Republic.

Security posture

The security posture is moderate but lacks several best practices. HTTPS is presumably enabled but not explicitly confirmed. No security headers such as Content Security Policy, HSTS, or X-Frame-Options are present, which could expose the site to common web attacks. The absence of privacy and cookie policies indicates non-compliance with GDPR requirements. No vulnerability disclosure or incident response information is available, limiting the ability to report or handle security issues. No forms with sensitive inputs are present on the main page, reducing immediate risk. Overall, the site would benefit from implementing security headers, privacy documentation, and incident response contacts to enhance security maturity.

Recommendations

  1. Implement and publish a comprehensive privacy policy and cookie policy to ensure GDPR compliance.
  2. Add standard security headers such as Content Security Policy, HSTS, X-Frame-Options, and X-Content-Type-Options.
  3. Provide clear contact information including email and phone for customer support and security incident reporting.
  4. Consider adding a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  5. Enhance SEO and accessibility features to improve site reach and usability.

Technical notes

Notes

The website uses a simple, custom-built front-end with HTML, CSS, and JavaScript. There is no evidence of a CMS or third-party frameworks. Hosting is managed by WEDOS, a Czech provider, consistent with the domain registration. Performance is moderate with responsive design and a user-friendly carousel component. No external analytics or advertising scripts were detected, indicating minimal tracking. The site lacks advanced SEO metadata and structured data, which could be improved for better search engine visibility. No technical debt or deprecated technologies were observed, but security and privacy technical implementations require enhancement.
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.
