59/100

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

Rustler Gruppe is a well-established Austrian real estate services company with a strong market position in property management, brokerage, development, facility management, and construction project management. Founded in 1935, it operates primarily in Austria and Central and Eastern Europe, targeting property owners, tenants, and investors. The website reflects a professional digital presence with comprehensive service descriptions and multilingual support. Technically, the site is built on WordPress using the Enfold theme and several plugins including Yoast SEO and Borlabs Cookie for privacy compliance. However, the security posture is weak due to the absence of a valid SSL certificate and disabled TLS protocols, exposing users to potential risks. Privacy compliance is well addressed with cookie consent mechanisms and detailed policies. Overall, the site is professional and trustworthy but requires urgent security improvements to protect user data and enhance trust.

Scanned

3 of 7 checks could not complete. The site may be unreachable or blocking automated scans, so the results below cover only what could be checked. Try a rescan later.

NIS2 and GDPR posture

NIS2 outside view
Not assessed
GDPR outside view
Not assessed

Both readouts depend on the site's pages, which could not be loaded in this scan.

Priority findings

1 finding 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

      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

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

  • Security headers: did not complete in this scan.
  • GDPR outside view: did not complete in this scan.
  • 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

Rustler Gruppe leverages its long history and family-owned status to position itself as a market leader in real estate services. Its diversified service portfolio includes property management, brokerage, facility management, and development, catering to a broad client base in Austria and neighboring CEE countries. The company maintains certifications and memberships that enhance credibility. The website supports recruitment efforts and client engagement through detailed career pages and contact options. Marketing and analytics tools like Google Analytics and Facebook Pixel are used responsibly with user consent. The company’s digital ecosystem includes social media channels to strengthen brand presence and customer interaction.

Security posture

The website’s security posture is currently inadequate. The lack of a valid SSL certificate and disabled TLS protocols mean that data transmitted between users and the site is not encrypted, posing significant risks of interception and data compromise. While security headers such as Content Security Policy, X-Frame-Options, and X-XSS-Protection are implemented, the absence of HTTPS severely undermines overall security. No incident response or security policy pages were found, indicating potential gaps in security governance. The cookie consent mechanism is robust, supporting GDPR compliance. Immediate remediation of SSL/TLS issues is critical to safeguard user data and maintain regulatory compliance.

Recommendations

  1. Obtain and install a valid SSL/TLS certificate to enable HTTPS across the entire site.
  2. Enable modern TLS protocols (TLS 1.2 and TLS 1.3) and disable insecure protocols.
  3. Enhance HSTS policy by enabling it with includeSubDomains and preload directives.
  4. Develop and publish a formal security policy and incident response plan accessible on the website.
  5. Conduct regular security audits and vulnerability assessments to identify and mitigate risks.
Technical notes

Notes

The website is built on a mature WordPress platform using the Enfold theme, with multiple plugins for SEO, multilingual support, cookie management, and content display. The tech stack includes jQuery and various JavaScript libraries. Performance metrics are not available, suggesting a need for monitoring and optimization. The site is mobile responsive with good SEO metadata including Open Graph and JSON-LD structured data. Hosting details are limited but DNS records are properly configured. The absence of SSL and disabled TLS protocols represent significant technical debt and security risk. Overall, the infrastructure is functional but requires modernization and security hardening.
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.
