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

SELA Immo is a regional real estate company specializing in the sale and rental of land, houses, and apartments primarily in the Loire-Atlantique region of France. The website serves both individual consumers and professional clients, offering property listings, advice, and partnership opportunities with construction companies. The company positions itself as a trusted local real estate developer with a focus on sustainable and community-oriented projects. Technically, the website is built on WordPress with common plugins such as Yoast SEO and Google Analytics, providing a modern and responsive user experience. However, some technical improvements are possible, including better security header implementation and full configuration of analytics tools. Security posture is adequate with HTTPS enforced and cookie consent mechanisms in place, but lacks explicit security policies and incident response information. The absence of WHOIS data for the domain reduces trustworthiness and warrants further investigation. Overall, the website is professional, content-rich, and compliant with GDPR privacy requirements, making it a credible platform for real estate services in its market niche.

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

9 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. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  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

      Missing Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

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

SELA Immo operates in the real estate sector with a medium-sized business model focused on regional property sales and rentals. Its competitive advantage lies in localized expertise and partnerships with construction firms, enabling it to offer tailored property solutions including land and new housing developments. The company targets both private individuals and professional clients, expanding its market reach. The website's content and structure support lead generation and customer engagement through catalog requests and contact forms. The partnership ecosystem includes related real estate sites and construction collaborators. Growth indicators include active property listings and regular news updates. The business model relies on commissions from property sales and rentals, as well as value-added services such as real estate advice and project support.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enabled and a cookie consent banner indicating GDPR awareness. However, it lacks several recommended security headers that could mitigate common web vulnerabilities. No explicit security or incident response policies are published, and no vulnerability disclosure or security.txt files are present. The Google Analytics plugin is installed but not fully configured, which may impact data privacy compliance. No exposed sensitive data or known vulnerabilities were detected in the HTML content. The absence of WHOIS data is a concern for domain legitimacy verification but does not directly indicate a security risk. Overall, the security posture is adequate for a real estate website but could be improved with enhanced headers, documented policies, and better analytics configuration.

Recommendations

  1. Implement standard security headers including Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, and Strict-Transport-Security to enhance protection against common attacks.
  2. Complete the configuration of Google Analytics via the MonsterInsights plugin to ensure accurate tracking and compliance with privacy regulations.
  3. Publish explicit security and incident response policies on the website to improve transparency and preparedness.
  4. Add a security.txt file to facilitate responsible vulnerability disclosure and improve security communication.
  5. Enhance accessibility features to meet compliance standards and improve user experience for all visitors.

Technical notes

Notes

The website is built on WordPress CMS version 6.8.3, utilizing popular plugins such as Yoast SEO for search engine optimization and MonsterInsights for analytics integration. The front-end uses Bootstrap for responsive design, jQuery for scripting, and Flexslider and Magnific Popup for interactive UI elements. The site loads external scripts asynchronously to improve performance. The presence of a cookie consent plugin indicates attention to privacy compliance. The website is hosted on a platform supporting HTTPS with a valid SSL certificate. Performance is moderate with room for optimization, particularly in accessibility and security header implementation. The technical stack is modern and widely supported, but some plugins like MonsterInsights are not fully configured, which may affect data collection accuracy and privacy compliance.
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.
