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

etg24 GmbH is a German-based company specializing in digital real estate management solutions. Positioned as the original and first provider of online customer portals tailored specifically for property management, etg24 targets property managers, owners, tenants, and service providers. Their business model centers on providing SaaS platforms that streamline and modernize property management processes. The website reflects a professional and consistent brand image with good content quality and clear target audience focus. Technically, the website is built on WordPress using Elementor and WooCommerce, supported by modern tools such as Yoast SEO and Google Tag Manager. Hosting is managed via INWX, a reputable German hosting provider. The site demonstrates moderate performance and good mobile optimization, with basic accessibility features and solid SEO practices. From a security perspective, the site enforces HTTPS and uses a cookie consent mechanism via Borlabs Cookie, indicating awareness of privacy regulations. However, explicit security headers are not fully implemented, and no formal privacy policy or terms of service are found, which are areas for improvement. No vulnerabilities or exposed sensitive data were detected, and no WAF or blocking mechanisms interfere with access. Overall, etg24 presents a trustworthy and professional digital presence with a solid foundation. Strategic improvements in privacy documentation and security header implementation would enhance compliance and security posture, supporting their market credibility and customer trust.

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. 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

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  2. 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';…

  3. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

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

etg24 GmbH operates in the real estate sector, focusing on digital transformation of property management through SaaS portals. Their competitive advantage lies in being the first mover in Germany offering specialized online portals for property managers and stakeholders. Revenue streams likely include subscription fees for portal access and related digital services. The target customer segments include property managers, owners, tenants, and service providers, indicating a B2B and B2C hybrid approach. The company leverages partnerships with marketing and CRM tools such as Pipedrive. Growth indicators include positive aggregate ratings and professional digital marketing infrastructure. The company maintains a focused ecosystem with no detected subsidiaries or parent companies, emphasizing a specialized niche market presence.

Security posture

The website demonstrates a moderate to good security maturity level. HTTPS is enforced, and cookie consent is managed via Borlabs Cookie, supporting GDPR compliance. The use of Google Tag Manager is consent-aware. However, the absence of explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options represents a compliance and security gap. No incident response contacts or vulnerability disclosure policies are published, limiting transparency in security incident handling. No exposed credentials or vulnerabilities were detected in the HTML content. Overall, the security posture is adequate for the business type but would benefit from enhanced header implementation and formalized security policies.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service accessible from the website footer or main navigation.
  2. Implement and configure security headers including Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, and Referrer-Policy to enhance protection against common web attacks.
  3. Establish and publish an incident response contact email (e.g., security@etg24.de or abuse@etg24.de) to improve transparency and readiness.
  4. Consider creating a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  5. Regularly audit third-party scripts and libraries for vulnerabilities and update them to maintain security hygiene.

Technical notes

Notes

The website is built on a modern WordPress CMS platform using Elementor for page building and WooCommerce for e-commerce capabilities. The tech stack includes jQuery, FontAwesome, Google Tag Manager, and Borlabs Cookie for consent management. Hosting is provided by INWX, a reputable German provider. The site shows good mobile responsiveness and SEO optimization through Yoast SEO. Performance is moderate, with minified CSS and JS assets indicating optimization efforts. Technical debt appears low, but opportunities exist to improve security headers and formalize privacy and security documentation. The integration of marketing tools like Pipedrive LeadBooster indicates a mature digital marketing approach supporting business growth.
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.
