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

10 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

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 business operates in the real estate legal services sector, specifically targeting leasehold notarial services in Amsterdam. Its competitive advantage lies in specialization and process efficiency. The business model is service-oriented, relying on direct client engagement. The website suggests a small-sized operation with no parent or subsidiary companies mentioned. The company maintains a professional online presence with consistent branding and clear contact channels. There is no evidence of partnerships or affiliate programs. Growth indicators are not explicit but the niche focus suggests stable market positioning. The marketing ecosystem includes standard analytics and retargeting tools but lacks advanced marketing automation or affiliate networks.

Security posture

The website demonstrates a basic to moderate security maturity level. HTTPS is properly implemented, ensuring encrypted communications. However, the absence of security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security reduces protection against common web attacks. No incident response or security policy is published, which may impact trust and readiness for security events. No vulnerabilities or exposed sensitive data were detected in the HTML content. The site lacks a vulnerability disclosure policy or security.txt file, limiting transparency for security researchers. Privacy compliance is minimal, with no cookie consent mechanism detected, which may pose regulatory risks under GDPR. Overall, the security posture is adequate for a small professional service website but could be significantly improved.

Recommendations

  1. Implement and configure security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to enhance protection.
  2. Add a cookie consent banner and detailed cookie policy to comply with GDPR and improve user privacy transparency.
  3. Publish a security policy and incident response contact information to build trust and readiness.
  4. Consider creating a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  5. Regularly review and update privacy policies to ensure full GDPR compliance and communicate data retention practices.

Technical notes

Notes

The website is built on WordPress CMS with the Yoast SEO plugin, indicating a modern and SEO-friendly platform. It uses Google Fonts, Google Analytics, Facebook Pixel, and Bing UET for tracking and marketing analytics. The site loads multiple JavaScript libraries including jQuery and WordPress core scripts. Performance is moderate with no evident critical errors or broken elements. Mobile optimization is good with responsive design and adaptive images. Accessibility features are basic but present. The site lacks advanced frameworks or custom backend technologies visible from the front-end. Hosting provider details are not explicitly found. Overall, the technical infrastructure is standard for a small professional service website with room for modernization and security enhancements.
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.
