31/100

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

Merkur.si is a large Slovenian retail company specializing in home improvement, construction, gardening, personal care, and energy solutions. The company operates both physical stores and an extensive e-commerce platform, offering a wide range of products and services including financing options and expert consultations. The website is well-designed, user-friendly, and rich in content, targeting Slovenian consumers and businesses. Technically, the site is built on Magento with modern JavaScript frameworks and integrates multiple third-party marketing and analytics tools. However, the absence of a valid SSL certificate and HTTPS support is a critical security gap, exposing users to potential risks. The site implements several security headers and privacy policies with consent mechanisms, indicating good privacy compliance. Overall, the business is legitimate and well-established, but urgent improvements in SSL/TLS implementation are recommended to enhance security and trust.

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

    • Critical

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

    • 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

      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. 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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

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

  • Security headers: did not complete in this scan.
  • 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

Merkur.si holds a strong market position as a leading retail chain in Slovenia, with a comprehensive product catalog spanning multiple sectors such as home improvement, energy, and personal care. The business model combines physical retail with e-commerce, supported by loyalty programs and financing services. The company leverages partnerships with payment processors like PayPal and Braintree, and financing providers such as Leanpay. The website's extensive navigation and detailed product categorization reflect a mature digital presence. The company demonstrates commitment to customer engagement through social media and personalized marketing. No suspicious patterns were found in WHOIS data, confirming the legitimacy and consistency of the business identity.

Security posture

The website exhibits a moderate security posture with several positive practices including the use of Content-Security-Policy (report-only), X-Content-Type-Options, X-XSS-Protection, and X-Frame-Options headers. However, the lack of a valid SSL certificate and absence of HTTPS significantly undermine the security posture, exposing users to data interception and man-in-the-middle attacks. No critical vulnerabilities such as Heartbleed or POODLE were detected, but the site does not support modern TLS protocols or strong cipher suites. The site lacks OCSP stapling and session resumption features. It is recommended to prioritize SSL/TLS deployment and enhance cryptographic configurations to meet current security standards.

Recommendations

  1. Obtain and deploy a valid SSL/TLS certificate to enable HTTPS across the entire site.
  2. Enable and enforce modern TLS protocols (TLS 1.2 or 1.3) and strong cipher suites to secure data in transit.
  3. Transition Content-Security-Policy from report-only to enforce mode after thorough testing to mitigate XSS risks.
  4. Implement OCSP stapling and session resumption to improve security and performance.
  5. Conduct regular security audits and update third-party libraries to avoid vulnerabilities.
  6. Enhance accessibility features to improve user experience for all users.
  7. Maintain transparency in privacy and cookie policies and ensure ongoing GDPR compliance.
  8. Consider publishing a security policy and incident response contact information to improve trust.
Technical notes

Notes

The website is built on the Magento platform, utilizing modern JavaScript libraries such as jQuery and Alpine.js, and UI components like Swiper.js for carousels. It integrates multiple marketing and analytics tools including Google Tag Manager, Adobe DTM, Nosto personalization, and New Relic monitoring. The site is mobile-optimized with responsive design and features comprehensive navigation and content structure. However, the absence of HTTPS and valid SSL certificate is a significant technical deficiency. Performance data was not available, but the site uses caching (Magento cache HIT) and CDNs for static content delivery. The technical stack is mature but requires urgent security upgrades to align with best practices and ensure safe user interactions.
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.
