Risk levelHigh

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

The website doublegroup.se serves as an informational platform aggregating various home improvement services such as painting, roofing, carpentry, and renovations primarily targeting Swedish homeowners. The content is comprehensive and well-structured, providing detailed guidance and advice on selecting professionals and undertaking home projects. Technically, the site employs standard web technologies including Bootstrap and jQuery, delivering a moderately optimized and mobile-friendly experience. However, the absence of privacy policies, contact information, and security headers indicates gaps in compliance and security posture. Critically, the WHOIS lookup for the domain www.doublegroup.se failed, suggesting the domain may be unregistered or a subdomain, which raises legitimacy concerns. Overall, while the site offers valuable content, its security and compliance maturity require significant improvement.

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

11 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

Doublegroup operates as a small-scale, niche service information provider within the Swedish home improvement sector. Its business model appears to focus on aggregating and promoting local service providers in painting, roofing, carpentry, and renovation. The website links to multiple external domains related to these services, indicating a partnership or referral ecosystem. The lack of direct contact details or transactional capabilities suggests the site functions primarily as a referral or informational hub rather than a direct service provider. Market positioning is localized with a focus on Swedish homeowners seeking professional tradespeople. Growth potential depends on establishing trust, improving compliance, and possibly integrating direct service offerings or lead generation.

Security posture

The current security posture of the website is weak. There is no evidence of HTTPS enforcement or security headers such as Content-Security-Policy or X-Frame-Options. The absence of privacy and cookie policies indicates non-compliance with GDPR and related regulations. No incident response or vulnerability disclosure information is provided, limiting transparency and preparedness. The missing WHOIS data for the domain further undermines trust and raises questions about domain ownership and legitimacy. To improve, the site should implement HTTPS, add security headers, publish privacy and cookie policies, and provide clear contact channels for security incidents.

Recommendations

  1. Implement HTTPS with a valid SSL certificate to secure user connections.
  2. Add comprehensive privacy and cookie policies to comply with GDPR and enhance user trust.
  3. Publish clear contact information including emails and phone numbers for customer and security incident communication.
  4. Configure security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  5. Verify and register the primary domain properly to resolve WHOIS inconsistencies and improve legitimacy.

Technical notes

Notes

The website uses a conventional tech stack with Bootstrap 4.7.0 for responsive design, jQuery 3.3.1 for scripting, and Font Awesome 4.7.0 for icons. The HTML structure is valid and content is well organized, supporting good mobile optimization and user experience. However, there is no evidence of a CMS or advanced frameworks, indicating a static or simple dynamic site. Performance is moderate with no explicit optimization techniques detected. The lack of analytics or tracking scripts suggests minimal data collection. Technical risks include missing HTTPS and security headers, which expose the site to potential attacks and reduce user trust. Modernization opportunities include adopting HTTPS, enhancing SEO metadata, and integrating privacy compliance tools.
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.
