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

9 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

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, LinkedIn, YouTube, Cloudflare, Google APIs

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

    • High

      Missing Strict-Transport-Security header

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

DARCO operates in the energy sector focusing on ventilation and heating products. Its business model includes manufacturing, sales through e-commerce and B2B platforms, and technical consulting. The company maintains multiple subdomains for specialized services such as online stores, price lists, and cooperation platforms, indicating a diversified digital ecosystem. The presence of social media channels and multilingual support suggests an intent to reach broader audiences. The domain age and consistent branding reinforce its credibility. However, the absence of explicit privacy policies and contact details on the main page may limit trust for some users. The company appears to be medium-sized with a solid foothold in the Polish market.

Security posture

The website uses HTTPS, ensuring encrypted communication. It employs a GDPR cookie compliance plugin, indicating awareness of privacy regulations. However, no security headers like Content-Security-Policy or X-Frame-Options were detected, which could enhance protection against common web attacks. There is no visible security policy or incident response contact information, nor a vulnerability disclosure or security.txt file. The WHOIS data shows no DNSSEC enabled, which is a recommended DNS security feature. No vulnerable libraries or exposed sensitive data were found in the HTML. Overall, the security posture is moderate but could be improved by implementing additional headers, publishing security policies, and enabling DNSSEC.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Implement security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to harden the website against attacks.
  3. Publish a clear privacy policy and terms of service pages accessible from the main navigation.
  4. Add a security policy and incident response contact information, including a security.txt file for vulnerability disclosures.
  5. Improve accessibility features to comply with standards and enhance user experience for all users.

Technical notes

Notes

The website is built on WordPress CMS using a variety of popular plugins including WPBakery Page Builder, Slider Revolution, WPML for multilingual support, Contact Form 7, and GDPR Cookie Compliance. It uses jQuery and Font Awesome for UI elements. Google Analytics and Google Tag Manager are integrated for analytics and marketing. The site is responsive and optimized for mobile devices. Performance is moderate, with some heavy slider elements that may impact load times. SEO is supported by Yoast SEO plugin and proper meta tags including Open Graph and JSON-LD structured data. Hosting provider details are not explicitly available. The site lacks advanced security headers and DNSSEC. Overall, the technical infrastructure is modern but could benefit from performance tuning and enhanced security configurations.
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.
