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

6 findings rated critical or high. Fix these first.

  1. 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

  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. GDPR outside view

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

    • 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

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 operates in the water hygiene and treatment sector, serving industrial and commercial clients. Their business model focuses on service delivery including testing, analysis, treatment, and certification. They maintain industry certifications and associations, enhancing market credibility. The website content and structure indicate a small-sized enterprise with a focused regional market. Their partnership with recognized accreditation bodies and hosting provider Cyber Sushi Design supports operational reliability. The presence of testimonials and detailed service descriptions suggests a customer-centric approach with growth potential in compliance-driven markets.

Security posture

The website employs HTTPS and secure contact forms with CAPTCHA, reducing risk of automated abuse. However, the absence of key security headers such as Content-Security-Policy and Strict-Transport-Security represents an area for improvement. No exposed sensitive data or vulnerable libraries were detected. Privacy compliance is partial, with a privacy policy present but no cookie consent mechanism. Incident response and security policy information are not published, which could impact trust and readiness. Overall, the security maturity is moderate, suitable for the business size but with room for enhancement to meet higher compliance standards.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to enhance protection against common web attacks.
  2. Add a cookie policy and explicit consent mechanism to comply fully with GDPR and ePrivacy regulations.
  3. Publish a security policy and incident response contact details to improve transparency and preparedness.
  4. Regularly audit and update WordPress plugins and themes to mitigate vulnerabilities.
  5. Enhance accessibility features to improve compliance and user experience for all visitors.

Technical notes

Notes

The website is built on WordPress CMS using popular plugins such as Yoast SEO, LayerSlider, Revolution Slider, and Contact Form 7. It uses jQuery and Google Analytics for tracking. Hosting is provided by Cyber Sushi Design. The site is mobile responsive with good SEO metadata including Open Graph and JSON-LD structured data. Performance is moderate with some heavy slider elements. Accessibility is basic but could be improved. The technical stack is modern and well-supported, though security headers and cookie management need attention to reduce risk and improve compliance.
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.
