Risk levelMedium

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

Jablotron Alarmsysteme s.r.o. is a medium-sized technology company specializing in the development and manufacture of security systems and smart home solutions. The company targets both residential and commercial customers, offering alarm systems, smart home automation, and security monitoring services. The website reflects a professional and consistent brand image with comprehensive privacy and cookie policies, indicating compliance with GDPR regulations. Technically, the site is built on modern frameworks such as Next.js and React, with good mobile optimization and security headers in place. However, the absence of publicly available WHOIS data limits the ability to fully verify domain legitimacy. Security posture is solid with HTTPS enforcement and security best practices, though the lack of a dedicated security policy or vulnerability disclosure page suggests room for improvement. Overall, the website is safe, trustworthy, and well-structured, serving its business purpose effectively.

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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

  2. GDPR outside view

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

    • 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

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, LinkedIn, YouTube, Google APIs

      What to do: Document all third-party data sharing in your privacy policy

  3. 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
    • High

      Weak SSL Key Length

      SSL certificate uses 384-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

Jablotron holds a strong position in the European security technology market, leveraging a B2B and B2C business model. Their product portfolio focuses on integrated security and smart home solutions, appealing to homeowners and security professionals alike. The company maintains a professional online presence with clear contact channels and social media engagement, supporting customer interaction and brand trust. While the domain registration details are not publicly available, the company's established market presence and consistent branding mitigate some concerns. The website's moderate performance and good SEO practices support customer acquisition and retention. Strategic partnerships and certifications were not explicitly found, suggesting potential areas for business development and trust enhancement.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, comprehensive security headers, and no visible exposure of sensitive data. The use of Google reCAPTCHA indicates protection against automated abuse. However, the absence of a published security policy, incident response information, and vulnerability disclosure mechanisms limits transparency and preparedness perception. No critical vulnerabilities or outdated libraries were detected in the provided content. Compliance with GDPR is evident through privacy and cookie policies. To elevate security maturity, Jablotron should consider publishing detailed security and incident response policies and implementing a vulnerability disclosure program. These steps would enhance customer trust and demonstrate proactive security management.

Recommendations

  1. Publish a dedicated security policy and incident response page to improve transparency.
  2. Implement a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  3. Enhance website accessibility features to comply with best practices and broaden user inclusivity.
  4. Regularly audit third-party scripts and libraries to ensure no vulnerabilities are introduced.
  5. Maintain updated WHOIS information or use verified domain registration to improve trust signals.

Technical notes

Notes

The website is built using modern web technologies including React and Next.js, styled with Tailwind CSS, indicating a contemporary and maintainable codebase. Performance is moderate, with good mobile responsiveness and SEO optimization. Security headers and HTTPS are properly configured, contributing to a secure browsing experience. The site uses Google Analytics and Tag Manager for analytics and marketing, with cookie consent mechanisms in place. No CMS was detected, suggesting a custom or framework-based solution. Hosting provider details were not identified. Opportunities exist to improve accessibility and to publish more comprehensive security documentation. Overall, the technical infrastructure supports the business goals effectively with room for incremental improvements.
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.
