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

RIWOG Real Estate Management GmbH operates as a medium-sized real estate group based in Austria, offering comprehensive property brokerage, management, and related services. The website targets property buyers, sellers, and investors primarily in Austria with some international presence in Greece and Spain. The business model focuses on real estate marketing, development, and client services including financing and valuation. The company maintains a professional online presence with clear branding and detailed legal disclosures, supporting its market position as a reputable real estate service provider. Technically, the website is built on SilverStripe CMS with modern JavaScript frameworks and integrates common marketing and analytics tools such as Google Analytics and Facebook Pixel. However, the site lacks a valid SSL certificate, serving content over HTTP only, which significantly impacts its security posture. Privacy and cookie policies are comprehensive and GDPR compliant, with consent mechanisms implemented. Security best practices are partially implemented but critical improvements are needed in SSL/TLS configuration and security headers. Overall, the website is functional and professional but requires urgent security enhancements to protect user data and improve 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

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

    • 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"

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

Business profile

RIWOG holds a solid position in the Austrian real estate market with a clear focus on brokerage and property management services. The company operates subsidiaries such as RIWOG Holding GmbH and partners with service providers like immo-billie for bidding processes. Revenue streams likely derive from brokerage commissions, property sales, rentals, and financing services. The target customer segments include residential and commercial property buyers, sellers, and investors. The website content and structure support lead generation and client engagement through search forms and service portals. The partnership ecosystem includes marketing and technical agencies, enhancing digital presence. Growth indicators include a broad portfolio of national and international projects and a comprehensive service offering. Strategic observations suggest the company benefits from transparent legal compliance and professional branding but must address technical security gaps to maintain competitive advantage.

Security posture

The current security maturity level of the website is low due to the absence of a valid SSL certificate and HTTPS enforcement, exposing users to potential data interception risks. While no critical vulnerabilities such as Heartbleed or POODLE are detected, the lack of HSTS, security headers, and OCSP stapling indicates incomplete security hardening. The website uses third-party scripts for analytics and marketing, which are managed with a consent mechanism, supporting GDPR compliance. However, no explicit incident response or vulnerability disclosure policies are present, limiting preparedness for security incidents. Data protection practices are documented in a comprehensive privacy policy, but technical controls need strengthening. The security culture appears basic, with room for improvement in proactive security measures and transparency. Business impact of current vulnerabilities includes reputational risk and potential non-compliance with evolving security standards.

Recommendations

  1. Install and configure a valid SSL/TLS certificate to enable HTTPS across the entire website immediately.
  2. Implement HTTP Strict Transport Security (HSTS) with includeSubDomains and preload directives.
  3. Add essential security headers such as Content-Security-Policy, X-Frame-Options, X-XSS-Protection, and Referrer-Policy.
  4. Develop and publish a formal security policy and incident response plan accessible to users and partners.
  5. Regularly audit and update all third-party scripts and libraries to mitigate vulnerabilities and ensure compliance.

Technical notes

Notes

The website is hosted on an nginx server with IP 88.198.80.147 and uses SilverStripe CMS as its content management system. The front-end leverages JavaScript libraries including Knockout.js for dynamic UI components. External resources include fonts from fast.fonts.net and integrations with Google Analytics, Facebook Pixel, Google Maps, YouTube, and immo-billie services. The site lacks performance metrics data, but the presence of multiple external scripts and chunked transfer encoding may impact load times. Mobile optimization is good with responsive design elements. SEO is supported by proper meta tags, Open Graph, and Twitter card metadata. Accessibility is basic with some ARIA and semantic HTML usage. Technical risks include missing HTTPS, lack of session resumption, and no OCSP stapling, which could affect user trust and search engine ranking. Modernization opportunities include performance optimization and enhanced security configurations.
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.
