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

Strantum OÜ is a small Estonian company providing essential municipal services such as water supply, heating energy, and maintenance for the Harku vald community. The company operates with a clear local focus, serving residents and property owners with utility and infrastructure services. The website reflects this local service orientation with content in Estonian and clear contact information. Technically, the site uses legacy JavaScript libraries and Cloudflare DNS/CDN services, with moderate performance and basic mobile optimization. Security posture is adequate with HTTPS and cookie consent implemented, but outdated libraries and lack of explicit security policies present moderate risks. Overall, the domain registration and website content are consistent and legitimate, supporting a trustworthy business presence.

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.

Priority findings

8 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

      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

Strantum OÜ holds a stable position as a local municipal service provider in Estonia, focusing on energy and water utilities. Its business model relies on service fees from residents and contracts with local government entities. The company maintains a straightforward digital presence with regular news updates and clear communication channels. While no advanced marketing or analytics tools are used, the company benefits from Cloudflare's infrastructure for performance and security. Growth indicators are limited but the company appears well integrated into the local community ecosystem.

Security posture

The website enforces HTTPS and includes a cookie consent mechanism, indicating awareness of privacy compliance. However, the use of an outdated jQuery version (1.8.1) introduces potential vulnerabilities. No security headers were detected, and there is no published security policy or incident response contact information. The absence of a vulnerability disclosure or security.txt file limits transparency. Overall, the security posture is moderate but could be significantly improved by updating libraries, adding security headers, and publishing security policies.

Recommendations

  1. Update all JavaScript libraries, especially jQuery, to the latest secure versions to mitigate known vulnerabilities.
  2. Implement standard security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to enhance protection.
  3. Publish a clear security policy and provide incident response contact information to improve transparency and trust.
  4. Conduct regular security audits and vulnerability assessments to proactively identify and remediate risks.
  5. Enhance website accessibility and SEO to improve user experience and compliance with best practices.

Technical notes

Notes

The website uses legacy JavaScript libraries including jQuery 1.8.1 and jQuery UI, which are outdated and pose security risks. The site is hosted behind Cloudflare, benefiting from CDN and DNS services, and uses HTTPS with a valid SSL configuration. Performance is moderate with basic mobile optimization and accessibility features. The site lacks modern frameworks or CMS indications and does not use structured data markup. SEO is basic with meta tags present but limited advanced optimization. Overall, the technical infrastructure is functional but would benefit from modernization and security hardening.
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.
