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

Sixtyseven vastgoedcommunicatie is a medium-sized Dutch company specializing in real estate communication and marketing services. With over 30 years of experience, they provide end-to-end solutions including project branding, website development with interactive housing selectors, data-driven lead generation, and sales tracking via their proprietary SalesTracker system. Their client base includes prominent real estate developers, housing corporations, and municipalities primarily in the Netherlands but also internationally. The website reflects a professional and consistent brand image with a strong focus on data-driven marketing effectiveness. Technically, the website is built on WordPress using the Salient theme and integrates modern marketing and analytics tools such as Google Analytics, HubSpot, and Leadinfo. The site is mobile-optimized and employs standard security practices including HTTPS and cookie consent mechanisms. However, explicit security headers could be improved. The site shows good SEO and accessibility basics but could enhance accessibility compliance further. Security posture is solid with no visible vulnerabilities or exposed sensitive data. Privacy compliance is well addressed with a clear privacy policy and cookie consent banner. Contact information is transparent with a physical address, phone number, and contact forms. No terms of service or explicit security policies were found, which could be areas for improvement. Overall, the website and business appear legitimate, professional, and trustworthy with a good balance of technical maturity and business credibility. Strategic recommendations include enhancing security headers, publishing explicit security and incident response policies, and improving accessibility features.

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

6 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 Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  2. Security headers

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

Sixtyseven vastgoedcommunicatie holds a strong market position in the real estate marketing sector in the Netherlands, leveraging over three decades of experience. Their competitive advantage lies in their comprehensive service offering combined with proprietary technology (SalesTracker) that enables real-time sales tracking and lead qualification. Their business model focuses on B2B services targeting real estate developers, housing corporations, and municipalities. The company demonstrates growth potential through digital tools and data-driven marketing strategies. Their partnership ecosystem includes major real estate developers and municipalities, enhancing their market reach and credibility. The website content and client logos reinforce their established reputation and operational scale.

Security posture

The website exhibits a mature security posture with HTTPS enforced and cookie consent mechanisms in place, indicating GDPR awareness. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. Use of nonce tokens and AJAX in forms suggests secure form handling. However, the absence of explicit security headers like Content-Security-Policy and X-Frame-Options is a minor gap. There is no visible incident response or security policy documentation, which could limit transparency in case of security incidents. Overall, the security maturity is good but could be enhanced by publishing formal security policies and improving HTTP header configurations.

Recommendations

  1. Implement and enforce security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen browser security.
  2. Publish explicit security and incident response policies on the website to improve transparency and trust.
  3. Regularly update WordPress core, themes, and plugins to mitigate potential vulnerabilities.
  4. Enhance website accessibility compliance to improve inclusivity and meet legal standards.
  5. Consider adding a terms of service page to clarify user and client agreements.

Technical notes

Notes

The website is built on a modern WordPress CMS platform using the Salient theme and Visual Composer for page building. It integrates multiple third-party analytics and marketing tools including Google Analytics, Google Tag Manager, HubSpot Analytics, and Leadinfo for visitor tracking and lead generation. The site uses Gravity Forms for data collection with AJAX-enabled secure forms. Performance is moderate with some optimization possible. Mobile responsiveness is good, and SEO meta tags including Open Graph and JSON-LD structured data are properly implemented. The technical stack is standard for professional marketing websites, with opportunities to improve security headers and accessibility features.
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.
