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

5 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

      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 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

Mäklarhuset holds a strong market position as a large real estate brokerage in Sweden, with a business model focused on facilitating property transactions and providing valuation services. The website's content and structure indicate a customer-centric approach, emphasizing trust and service quality. The presence of international domains and career portals suggests strategic expansion and talent acquisition efforts. The company uses advanced marketing and analytics tools to optimize customer engagement and advertising effectiveness. The lack of direct contact emails or phone numbers on the site may be a deliberate choice to channel inquiries through forms, maintaining control over communication.

Security posture

The website demonstrates a high level of security maturity with enforced HTTPS, comprehensive security headers, and secure form implementations including CSRF tokens. The use of Cookiebot ensures compliance with cookie consent regulations, enhancing privacy protections. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, the absence of a public security policy, incident response information, and vulnerability disclosure mechanisms indicates potential gaps in transparency and readiness for security incidents. Addressing these gaps would strengthen the overall security culture and trustworthiness.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Provide clear incident response contact channels such as security@ or abuse@ email addresses.
  3. Implement and publicize a vulnerability disclosure policy to encourage responsible reporting.
  4. Enhance visible contact information to include direct phone numbers or emails for customer support.
  5. Regularly review and update third-party scripts and dependencies to mitigate potential vulnerabilities.

Technical notes

Notes

The website utilizes a modern technology stack including jQuery, UIkit framework, Google Tag Manager, Microsoft Clarity, Facebook Pixel, and Cookiebot for consent management. The site is well-structured with valid HTML and CSS, optimized for mobile devices and accessibility. Performance is moderate, with potential for improvement through optimization of third-party scripts and image loading. Hosting details are not explicitly identified, but the presence of Cloudflare-related domains suggests CDN usage. The technical implementation supports a professional and user-friendly experience, though continuous monitoring and modernization are advised to maintain performance and security.
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.
