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

3 findings rated critical or high. Fix these first.

  1. 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 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';…
  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.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

Proper operates in the Real Estate sector, targeting landlords and property managers primarily in Denmark. Their SaaS business model includes onboarding services to ease customer transition. The company was founded in 2019, consistent with domain registration data. Proper's competitive advantage lies in automating complex and time-consuming property management tasks, supported by a growing customer base. The website content and branding are consistent and professional, supporting a strong market position in the landlord software niche. The company leverages modern cloud infrastructure and third-party services for analytics, video hosting, and consent management, indicating a well-integrated technology ecosystem. No parent or subsidiary companies are identified, suggesting an independent operation. The absence of direct contact emails or phone numbers on the site may indicate a preference for contact via web forms or controlled channels.

Security posture

The website enforces HTTPS with strong SSL/TLS configuration and includes multiple security headers such as HSTS, X-Frame-Options, and Content-Security-Policy, reflecting good security hygiene. The domain is protected against unauthorized transfers with clientTransferProhibited status. Use of Sentry for error monitoring and LegalMonster for consent management indicates proactive security and privacy management. No vulnerable libraries or exposed sensitive data were detected in the HTML content. However, DNSSEC is not enabled, which could improve DNS security. The lack of a published security policy or incident response contact limits transparency and readiness communication. No security.txt or vulnerability disclosure program is present, which could be beneficial for responsible vulnerability reporting. Overall, the security posture is solid but could be enhanced with formalized policies and disclosure mechanisms.

Recommendations

  1. Enable DNSSEC on the domain to strengthen DNS security and prevent spoofing.
  2. Publish a dedicated security policy page outlining security practices and commitments.
  3. Establish and publish an incident response contact channel (e.g., security@ or abuse@ email).
  4. Implement a vulnerability disclosure program or security.txt file to facilitate responsible reporting.
  5. Consider listing a Data Protection Officer contact to enhance GDPR transparency and compliance.

Technical notes

Notes

The website is built using modern web technologies including React and Next.js, hosted on Vercel, and uses Sanity as a CMS. It integrates third-party services such as Wistia for video hosting, Google Tag Manager for analytics, Sentry for error tracking, and LegalMonster for consent management. The site is optimized for performance and mobile responsiveness, with good SEO and accessibility features. The domain uses Cloudflare DNS servers but does not have DNSSEC enabled. The technical stack and infrastructure indicate a mature and scalable platform with low technical debt. Opportunities exist to further improve security by enabling DNSSEC and formalizing security governance documentation.
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.
