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

4 findings rated critical or high. Fix these first.

  1. 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';…

  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

Denco Fluid Systems operates in the energy and manufacturing sectors, focusing on bespoke fluid system solutions for industrial clients. Their business model is B2B, providing tailored products and services such as lubrication systems, cooling solutions, filtration products, and condition monitoring. The company showcases a medium-sized operation with a professional team and a solid client base, including reputable international partners. Their market positioning as a leader is supported by client logos and testimonials on the website. The company maintains a clear partnership ecosystem and demonstrates growth potential through comprehensive service offerings and digital engagement.

Security posture

The website exhibits a good security maturity level with mandatory HTTPS enforcement and anti-spam protections. Cookie consent is implemented with granular user controls, reflecting GDPR compliance. However, the absence of key security headers like Content-Security-Policy and X-Frame-Options suggests room for improvement. No vulnerabilities or exposed sensitive information were found in the HTML content. Incident response and security policy documentation are not publicly available, indicating a potential compliance gap. Overall, the security posture is solid but could benefit from enhanced header configurations and formalized security communications.

Recommendations

  1. Implement comprehensive HTTP security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  2. Publish a dedicated security policy and incident response contact information to improve transparency and readiness.
  3. Maintain regular updates of WordPress core and plugins to reduce vulnerability risks.
  4. Enhance data protection practices by documenting data retention policies and DPO contact details.
  5. Continue to monitor and optimize privacy compliance mechanisms to align with evolving regulations.

Technical notes

Notes

The website leverages a modern WordPress CMS with Elementor page builder, integrating advanced JavaScript libraries such as Swiper.js for carousels and interactive UI components. It uses reputable third-party services for analytics (HubSpot, Microsoft Clarity) and anti-spam (CleanTalk). The site is well-optimized for performance and mobile responsiveness, with proper SEO meta tags and structured data enhancing search visibility. No technical debt or deprecated libraries were detected. Opportunities exist to improve security headers and further optimize accessibility 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.
