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

12 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

  2. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)

      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  3. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

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 · found on this site
  • 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 real estate developers seeking specialized marketing services to enhance sales and visibility of their projects. Its competitive advantage lies in deep industry knowledge, a broad portfolio of marketing products tailored to real estate, and active engagement through webinars and client education. The business model is service-oriented, focusing on bespoke marketing solutions rather than mass-market offerings. The presence of detailed case studies and client feedback indicates a mature client relationship management approach. The company leverages digital marketing tools and analytics to optimize campaigns and client engagement. No parent or subsidiary companies were identified, indicating an independent operation.

Security posture

The website maintains a good security baseline with enforced HTTPS and no visible leakage of sensitive information. However, the absence of DNSSEC and lack of explicit security headers such as Content-Security-Policy and X-Frame-Options represent areas for enhancement. The use of WordPress necessitates vigilant patch management to mitigate plugin or core vulnerabilities. No incident response or security policy information is publicly available, which could be improved to demonstrate security maturity. GDPR compliance is supported by a detailed privacy policy, but cookie consent mechanisms are missing, potentially exposing the company to compliance risks. Overall, the security posture is adequate but could benefit from implementing recommended best practices.

Recommendations

  1. Enable DNSSEC on the domain to strengthen DNS security and prevent spoofing.
  2. Implement and verify HTTP security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Add a visible and functional cookie consent banner to comply fully with GDPR and ePrivacy regulations.
  4. Publish a security policy and incident response contact information to enhance transparency and trust.
  5. Maintain regular updates of WordPress core and plugins to mitigate vulnerabilities and improve security posture.

Notes

The website is built on WordPress CMS with a modern front-end stack including jQuery, Slick Carousel, and Foundation Sites framework. It integrates Google Tag Manager, Google Analytics, and Facebook Pixel for marketing analytics and tracking. The site is hosted by LH.pl Sp. z o.o., a Polish hosting provider, with domain registration dating back to 2014. Performance is moderate with good mobile responsiveness and SEO optimization via Yoast SEO plugin. Accessibility features are basic but present. The site uses video backgrounds and image galleries effectively, enhancing user engagement. Some technical debt is noted in missing advanced security headers and cookie consent mechanisms. Overall, the technical infrastructure supports the business goals effectively with room for security and privacy 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.
