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.

    • 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

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

Semaco Real Estate operates in the competitive Kraków real estate market, leveraging extensive local knowledge and experience. Their business model focuses on brokerage and advisory services for residential properties, targeting buyers and sellers seeking quality apartments. The company’s competitive advantage lies in its deep expertise in both primary and secondary markets, a strong track record of successful transactions, and a network of partners supporting various aspects of the business. Revenue streams likely include commissions from sales and financing facilitation. The presence of partner logos and linked domains suggests a collaborative ecosystem enhancing service offerings. The company’s branding and messaging emphasize customer satisfaction and ecological building materials, aligning with market trends toward sustainable living.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and Google reCAPTCHA protecting user inputs. The absence of DNSSEC and security headers such as Content-Security-Policy or X-Frame-Options indicates potential vulnerabilities to DNS spoofing and clickjacking attacks. No incident response or security policy pages were found, which could hinder timely communication during security events. Data protection practices appear adequate with no exposed sensitive information. Compliance with GDPR is indicated by the presence of privacy and cookie policies. Overall, the security posture is acceptable for a small real estate business but would benefit from enhanced DNS security, security headers, and published incident response procedures.

Recommendations

  1. Enable DNSSEC on the domain to protect against DNS spoofing and improve domain security.
  2. Implement standard security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to mitigate common web attacks.
  3. Publish a dedicated security policy and incident response contact information to improve transparency and readiness.
  4. Regularly audit and update third-party scripts and libraries to minimize vulnerabilities.
  5. Enhance privacy compliance by detailing data retention policies and user rights in the privacy policy.

Technical notes

Notes

The website is built on a modern front-end stack using Bootstrap for responsive design and jQuery for interactivity. Carousels and sliders are implemented with Owl Carousel and Slick Carousel, providing a dynamic user experience. Google reCAPTCHA integration protects forms from spam and abuse. The site uses EstiCRM as its backend CMS, indicating a specialized real estate management platform. Hosting is likely provided by home.pl S.A., a reputable Polish hosting and registrar. Performance is moderate with lazy loading implemented for images, improving load times. SEO is supported by proper meta tags and structured navigation. Accessibility is basic but could be improved with ARIA attributes and better keyboard navigation support. Overall, the technical infrastructure is solid but could benefit from enhanced security configurations and accessibility improvements.
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.
