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

Nublu.ee is the official website for Nublu, a smart smoke and carbon monoxide detector product offered by G4S Eesti AS. The product uniquely combines traditional smoke detection with remote alerting capabilities and emergency service notification, targeting homeowners and families in Estonia concerned about fire and gas safety. The website content is professionally presented in Estonian with clear navigation and mobile optimization, reflecting a medium-sized business with a solid market position in the energy and security sector. Technically, the site uses modern JavaScript libraries, Google Tag Manager, and Cookiebot for consent management, with backend indications of Laravel framework usage. Security posture is good with HTTPS enforced and CSRF protections, though explicit security policies and incident response contacts are not published. Privacy compliance is supported by a comprehensive cookie consent mechanism, but a formal privacy policy page is not clearly found. Overall, the website demonstrates a mature digital presence with extensive tracking and advertising integrations, aligned with business credibility and trustworthiness.

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. 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

  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

      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';…

  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

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 under the G4S Eesti AS umbrella, leveraging its brand and security expertise to offer a unique smart home safety product. The business model combines hardware sales with monitoring services via G4S control centers, providing a competitive advantage in Estonia. The website integrates multiple advertising and analytics platforms, indicating active marketing and user behavior analysis. The absence of explicit privacy and security policies suggests areas for compliance improvement. The partnership ecosystem includes major ad networks and tracking services, while the parent company domain is clearly linked. Growth potential is supported by the innovative product offering and established brand trust.

Security posture

The website exhibits a good security baseline with HTTPS, CSRF tokens, and cookie consent management. However, it lacks published security policies, incident response contacts, and vulnerability disclosure mechanisms, which are important for transparency and trust. No critical vulnerabilities or exposed sensitive data were detected in the analyzed content. The use of third-party scripts and trackers is extensive, which may increase privacy risks if not properly managed. Security headers and advanced protections are not explicitly visible, suggesting room for enhancement. Overall, the security posture is adequate but could benefit from formalized policies and improved header configurations.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service pages accessible from the main navigation or footer.
  2. Implement and publish a security policy and incident response contact information to improve transparency.
  3. Add security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to enhance protection.
  4. Consider creating a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  5. Review third-party tracking scripts to ensure compliance with GDPR and minimize privacy risks.

Technical notes

Notes

The website is built on a modern JavaScript front-end with backend indications of Laravel PHP framework usage. It uses Google Tag Manager for analytics and marketing tag management, and Cookiebot for GDPR-compliant cookie consent. The site is hosted under a domain registered with Telia Eesti AS, a reputable Estonian registrar. Performance is moderate with mobile optimization and responsive design implemented. Accessibility features are basic but present. SEO optimization is basic with meta tags and viewport settings. The technical stack is solid but could be improved with enhanced security headers and formalized compliance documentation.
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.
