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

Rachuneo Sp. z o.o. operates an online comparison platform focused on helping Polish residential customers reduce their energy and home media bills by selecting optimal offers. The company positions itself as a niche player in the Polish energy sector, offering a user-friendly service to compare and lower household expenses. The website is professionally designed using Webflow CMS and integrates modern marketing and analytics tools such as Google Analytics, Hotjar, Facebook Pixel, and SalesManago, indicating a mature digital infrastructure. Security posture is strong with HTTPS enforced, cookie consent mechanisms in place, and no visible vulnerabilities or exposed sensitive data. However, the absence of public WHOIS data due to privacy protection limits domain registration transparency. Overall, the site is trustworthy, compliant with GDPR, and provides clear business and contact information, supporting its legitimacy and professional standing.

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

1 finding 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

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 targets Polish consumers seeking to optimize their energy and media bills, leveraging an online comparison model that generates revenue likely through partnerships or referrals with energy providers. The presence of partner domains like opineo.pl suggests a broader ecosystem for customer segmentation and marketing optimization. The business model is straightforward, focusing on cost savings and convenience for end-users. The company maintains active social media profiles on Facebook and LinkedIn, enhancing its market presence and credibility. While the domain registration is privacy-protected, the website content and structured data provide sufficient transparency about the business entity. Growth potential exists in expanding service offerings or geographic reach within Poland.

Security posture

The website demonstrates a solid security posture with HTTPS enabled and standard security headers likely managed via Cloudflare CDN. The use of Cookiebot ensures GDPR-compliant cookie consent management, and no sensitive data is exposed in the HTML content. Third-party scripts from trusted providers are used for analytics and marketing, though continuous monitoring for vulnerabilities in these dependencies is recommended. The lack of a dedicated security policy or incident response contact is a minor gap. No signs of malware, phishing, or other security threats were detected. Overall, the security maturity is appropriate for a small online service platform.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and user data protection.
  2. Add incident response contact information such as security@ or abuse@ email addresses.
  3. Regularly audit and update third-party scripts to mitigate potential vulnerabilities.
  4. Enhance website accessibility features to improve compliance and user experience.
  5. Consider implementing a vulnerability disclosure policy to encourage responsible reporting.

Technical notes

Notes

The website is built on Webflow CMS, leveraging modern web technologies and hosted likely on Webflow's infrastructure with Cloudflare CDN for performance and security. It integrates multiple marketing and analytics tools including Google Tag Manager, Hotjar, Facebook Pixel, and SalesManago, indicating a comprehensive approach to user behavior tracking and marketing optimization. The site is mobile-optimized with responsive design and uses proper meta tags for SEO. Performance is moderate, typical for CMS-based sites with multiple third-party scripts. There is room for improvement in accessibility and potential technical debt related to extensive third-party dependencies.
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.
