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

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 Cookie Policy found

      GDPR requires clear information about cookie usage

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

  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

LDI operates a B2B business model focused on manufacturing and supplying specialized environmental monitoring instruments. Their competitive advantage lies in their proprietary fluorescence-based optical sensors and global deployment experience. Revenue streams likely include product sales, technical support, and custom installations. The target customers are industrial operators, environmental agencies, and infrastructure managers concerned with water quality and pollution control. The company maintains partnerships and social media engagement to support sales and technical outreach. Growth indicators include a broad geographic footprint and diverse industry applications. Strategic observations suggest opportunities to enhance privacy compliance and security transparency to further build trust with enterprise clients.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, use of Google reCAPTCHA, and no visible exposure of sensitive data. However, the absence of advanced HTTP security headers and lack of published security policies or incident response information indicate room for improvement. No vulnerability disclosure or security.txt file was found, which is a gap for transparency. Cookie consent mechanisms are missing, which may impact GDPR compliance. Overall, the security maturity is good but could be elevated by adopting comprehensive security policies, enhanced headers, and formal vulnerability disclosure processes.

Recommendations

  1. Implement a cookie policy with explicit consent mechanism to improve GDPR compliance.
  2. Publish a dedicated security policy and incident response page to enhance transparency.
  3. Add a security.txt file to facilitate vulnerability reporting and responsible disclosure.
  4. Enhance HTTP security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  5. Improve website accessibility features to broaden usability and compliance.

Technical notes

Notes

The website is powered by WordPress CMS with WPBakery Page Builder and Redux Framework, supported by jQuery and Bootstrap for responsive design. Google Analytics and Tag Manager are used for analytics and marketing tracking. The site loads moderately fast with lazy loading images and optimized CSS. Hosting and domain registration are managed by Zone Media OÜ, an Estonian provider, consistent with the company location. The technical stack is modern and well-maintained, though some security headers are missing. The site is mobile optimized and SEO friendly with proper meta tags and structured data. Opportunities exist to improve accessibility and privacy compliance features.
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.
