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

Erik Olsson Fastighetsförmedling is a Swedish real estate brokerage firm with a strong regional presence in cities such as Stockholm, Göteborg, and Malmö. The company focuses on assisting clients in buying and selling residential properties, aiming to provide a secure and trustworthy real estate transaction experience. The website reflects a professional brand image consistent with the real estate industry in Sweden, targeting home buyers and sellers within the country. Technically, the website is built using modern web technologies including React and Next.js frameworks, with integrations of analytics and tracking tools such as Google Analytics, Hotjar, and Cookietractor. The site demonstrates good mobile optimization and a generally good user experience, although some accessibility features could be improved. Performance is moderate, and SEO practices appear adequate. From a security perspective, the website lacks visible security headers and explicit privacy or cookie policies in the provided content, which indicates room for improvement in compliance and security best practices. The absence of WHOIS data for the queried subdomain reduces confidence in domain registration legitimacy, although the website content and branding suggest a legitimate business. No critical vulnerabilities or adult content were detected. Overall, the website presents a moderate risk profile with recommendations to enhance security headers, privacy compliance, and domain registration transparency to improve trustworthiness and regulatory adherence.

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

8 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 Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

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

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, providing brokerage services primarily in Sweden's major cities. Its business model revolves around facilitating property transactions for buyers and sellers, leveraging a network of local agents. The website's content and design indicate a mature business with a clear market position as a trusted regional real estate agency. The use of multiple tracking and marketing tools suggests an active approach to customer engagement and lead generation. However, the lack of explicit contact details and privacy policies on the site may limit customer trust and regulatory compliance. There is no evidence of partnerships or subsidiaries from the provided data.

Security posture

The current security posture shows moderate maturity. The website uses HTTPS (implied by external script URLs using https), but no explicit security headers were detected in the provided data. The absence of privacy and cookie policies, as well as no visible incident response or security contact information, indicates gaps in compliance with GDPR and best security practices. The use of multiple third-party tracking scripts increases the attack surface and privacy risk. No exposed sensitive data or vulnerabilities were identified in the HTML content. The domain WHOIS data is missing, which raises concerns about domain registration transparency. Overall, the site would benefit from enhanced security controls, clear privacy documentation, and improved transparency.

Recommendations

  1. Implement and enforce security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to improve protection against common web attacks.
  2. Publish comprehensive privacy and cookie policies on the website, including GDPR compliance statements and user consent mechanisms.
  3. Verify and update domain WHOIS information to ensure transparency and trustworthiness of domain registration.
  4. Conduct regular security audits and vulnerability assessments to identify and remediate potential risks.
  5. Provide clear security incident response contact information and establish a vulnerability disclosure program to enhance security culture and customer trust.

Technical notes

Notes

The website is built on a modern React and Next.js stack, utilizing Chakra UI and Ant Design for UI components. It integrates several third-party services including Google Tag Manager, Hotjar, Cookietractor, and Adfenix for analytics and marketing. The site uses Typekit fonts for typography and appears to be optimized for mobile devices with responsive design. Performance is moderate, with many asynchronous scripts loaded to improve user experience. However, no CMS or hosting provider information was detected. Accessibility features are basic and could be improved. The lack of security headers and privacy policies indicates technical debt in security and compliance areas. Overall, the technical infrastructure supports a professional real estate website but requires enhancements in security and privacy implementation.
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.
