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

    • 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

    • High

    • 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

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 website holds a solid market position as a niche media platform in the housing and lifestyle sector. It leverages partnerships with related domains and maintains a newsletter and social media presence to engage its audience. The company benefits from a parent company, ABSTRACT s.r.o., which likely provides operational and strategic support. The content is relevant and professionally presented, targeting homeowners, renters, and lifestyle enthusiasts. Advertising and banner placements indicate monetization through ad networks like Adform.

Security posture

The site uses HTTPS and common web technologies including jQuery and Google Analytics. However, it lacks explicit security headers and uses an outdated jQuery version, which could pose security risks. No privacy or cookie policies are clearly presented, indicating compliance gaps with GDPR and related regulations. No incident response or vulnerability disclosure mechanisms are found. Overall, the security posture is moderate but could be improved by updating libraries, adding security headers, and formalizing privacy and security policies.

Recommendations

  1. Implement comprehensive privacy and cookie policies with user consent mechanisms to improve GDPR compliance.
  2. Update jQuery and other JavaScript libraries to current secure versions to mitigate vulnerabilities.
  3. Add security headers such as Content Security Policy (CSP), HSTS, and X-Frame-Options to enhance protection.
  4. Publish a security.txt file and establish clear incident response contact channels for vulnerability reporting.
  5. Enhance accessibility features and provide more detailed data retention and privacy disclosures.

Technical notes

Notes

The website uses a traditional tech stack with jQuery 1.11.1, Google Analytics, and Google Tag Manager. It employs responsive design techniques and includes SEO-friendly meta tags. Performance is moderate with CDN usage for static assets. The site lacks modern JavaScript frameworks or CMS identification but shows structured navigation and categorized content. Technical debt is indicated by outdated libraries and missing security headers. Opportunities exist to modernize the stack, improve performance, and enhance 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.
