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. 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

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • High

      Third-party services without privacy policy

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

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

  2. 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 company holds a strong market position in Estonia's security sector, leveraging its affiliation with the global G4S brand. Its business model focuses on providing comprehensive security services to both residential and commercial customers. The website highlights key services such as home alarm systems, video monitoring, manned security, and fire safety inspections. Partnerships with companies like AIKO and Nublu indicate a collaborative ecosystem enhancing their product offerings. The presence of multiple regional offices and a dedicated management center underscores operational scale and geographic coverage. The company actively communicates updates and security advisories through news posts, reflecting engagement with its audience. The business intelligence suggests a stable, growth-oriented enterprise with a diversified service portfolio and strong brand recognition.

Security posture

The website exhibits a solid security posture with HTTPS enforced and use of security best practices such as cookie consent and secure third-party integrations. While explicit security policies and incident response contacts are not published, the absence of exposed sensitive data and vulnerabilities is positive. The site could improve by publishing a dedicated security policy and implementing a security.txt file to facilitate vulnerability disclosures. Security headers are likely present but not explicitly visible in the HTML snapshot. Overall, the security maturity is good, with room for enhanced transparency and formalized incident response mechanisms.

Recommendations

  1. Publish a dedicated security policy page outlining security frameworks and practices.
  2. Implement and publish a security.txt file to support vulnerability disclosure.
  3. Ensure all recommended security headers (CSP, X-Frame-Options, X-Content-Type-Options) are set and verifiable.
  4. Regularly audit third-party scripts and dependencies for vulnerabilities.
  5. Enhance transparency by providing incident response contact channels.

Technical notes

Notes

The website is built using modern web technologies including React and Next.js, supported by a headless CMS (Strapi) and hosted on reliable infrastructure with Ultradns for DNS and AWS for media assets. Performance is optimized with image preloading, responsive design, and asynchronous script loading. The site integrates Google Tag Manager for analytics and Cookiebot for cookie consent management, reflecting compliance and marketing sophistication. Accessibility and SEO are well addressed with appropriate meta tags, Open Graph data, and structured navigation. The technical stack is current and well-maintained, supporting a fast and user-friendly experience. Opportunities exist to further enhance security headers and formalize security 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.
