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

Lundin Fastighetsbyrå is a well-established real estate agency based in Gothenburg, Sweden, with over 40 years of experience in providing comprehensive real estate brokerage services including property sales, valuations, buyer registration, and new production projects. The company positions itself as a trusted local expert with a strong market presence and a medium-sized team. The website reflects this professionalism with clear branding, consistent content, and a user-friendly interface targeting individuals looking to buy or sell properties in the Gothenburg area. Technically, the site employs modern JavaScript libraries and tracking tools with appropriate consent mechanisms, indicating a mature digital infrastructure. Security-wise, the site uses HTTPS and manages user consent effectively but lacks explicit security policies and some recommended HTTP security headers. Overall, the website is trustworthy and compliant with GDPR, though it could improve by publishing terms of service and incident response information.

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

7 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

    • Critical

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

  2. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

  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 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

The company operates in the real estate sector, focusing on residential properties such as villas, condominiums, plots, and holiday homes. Its business model revolves around brokerage services, property valuation, and customer engagement through buyer registries and tailored marketing. The firm has a strong local footprint in Gothenburg, supported by physical offices and a dedicated team. The presence of a career subdomain indicates organizational growth and talent acquisition efforts. The website content and structure support lead generation and customer service, with clear calls to action for property searches and valuation bookings. The company leverages social media and digital marketing tools to maintain visibility and customer engagement.

Security posture

The website demonstrates a moderate security posture with enforced HTTPS and cookie consent management aligned with GDPR. It uses Google Tag Manager and Facebook Pixel with consent restrictions to limit ad and analytics storage by default. However, the absence of explicit security headers such as Content-Security-Policy and Strict-Transport-Security reduces the overall security robustness. No incident response or security policy information is published, which could hinder transparency and preparedness. No vulnerabilities or exposed sensitive data were detected in the provided content. The site would benefit from enhanced security documentation and technical hardening to improve trust and resilience.

Recommendations

  1. Implement and publish a formal security policy and incident response contact details to improve transparency and preparedness.
  2. Add HTTP security headers including Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, and Strict-Transport-Security to enhance protection against common web attacks.
  3. Introduce a terms of service page to clarify user agreements and legal protections.
  4. Enhance accessibility features to meet higher compliance standards and improve user experience for all visitors.
  5. Regularly audit and update third-party libraries and tracking scripts to mitigate potential vulnerabilities.

Technical notes

Notes

The website uses a modern front-end technology stack including jQuery 3.7.1, Bootstrap, Swiper.js for sliders, AOS for animations, and Vimeo Player API for embedded videos. Fonts are loaded via Adobe Typekit. Google Tag Manager and Facebook Pixel are integrated for analytics and marketing, with consent management implemented. The site is mobile-optimized with responsive design and uses lazy loading for images to improve performance. No CMS is explicitly detected, suggesting a custom or proprietary platform. Performance is moderate, with room for optimization. The site lacks some advanced accessibility features but maintains basic usability standards. Hosting provider details are not evident from the content. Overall, the technical implementation supports a professional and functional user experience.
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.
