Risk levelHigh

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

S IMMO AG is a prominent Austrian real estate investment company with a diversified portfolio across several European Union countries. The company focuses on office, retail, hotel, and residential properties, targeting investors and stakeholders interested in European real estate markets. The website provides comprehensive corporate and investor relations information, including news updates and portfolio insights. Technically, the website is built on TYPO3 CMS and hosted on an Apache server with nameservers indicating a German hosting provider. However, the site lacks a valid SSL certificate, resulting in no HTTPS support, which is a critical security shortfall. The cookie consent mechanism and privacy policy are well implemented, indicating good privacy compliance. Security headers are minimal, and modern TLS protocols are not supported, which lowers the security posture significantly. Overall, the website is professional and content-rich but requires urgent improvements in security infrastructure to protect user data and enhance 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

10 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. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  4. 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

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 · found on this site
  • 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

The company holds a strong market position as Austria's first real estate investment firm with a broad European footprint. Its business model revolves around real estate investment and portfolio management, serving investors and real estate professionals. The website's content and navigation are well structured, supporting investor relations and corporate transparency. The absence of explicit contact emails and phone numbers on the main pages suggests a preference for contact via forms or dedicated contact pages. The company leverages Matomo analytics for user tracking with a moderate level of data collection and privacy compliance. Hosting and DNS records indicate a stable infrastructure, but the lack of SSL undermines trust. No evidence of partnerships or subsidiaries was found in the domain or website content.

Security posture

The security posture is weak due to the absence of a valid SSL certificate and HTTPS support, exposing users to potential data interception risks. Security headers are limited to 'X-Content-Type-Options' and 'X-UA-Compatible', with no HSTS or CSP headers present. TLS protocols are not supported, and no session resumption or OCSP stapling is configured. Vulnerabilities related to SSL/TLS are critical and must be addressed immediately. The cookie consent mechanism is implemented, and privacy policies are comprehensive, indicating awareness of privacy regulations. However, the lack of incident response contacts, security policies, or vulnerability disclosure pages suggests limited security governance transparency. Overall, the site requires significant security enhancements to meet modern standards and protect business and user data.

Recommendations

  1. Install and configure a valid SSL/TLS certificate to enable HTTPS across the entire site.
  2. Enable HTTP Strict Transport Security (HSTS) with includeSubDomains and preload options to enforce secure connections.
  3. Support modern TLS protocols (TLS 1.2 and TLS 1.3) and disable outdated protocols.
  4. Implement additional security headers such as Content-Security-Policy, X-Frame-Options, and Referrer-Policy.
  5. Provide explicit contact information including company emails and phone numbers for transparency and trust.
  6. Develop and publish a security policy and incident response contact information to improve security governance.
  7. Consider adding a vulnerability disclosure or security.txt page to encourage responsible reporting.
Technical notes

Notes

The website runs on TYPO3 CMS, a mature and extensible content management system, hosted on an Apache server with German-based nameservers. The site uses JavaScript and CSS assets loaded from its own domain. Performance metrics are not available, but the page size is approximately 25 KB, indicating a lightweight page. Mobile optimization appears good with responsive meta tags and mobile-friendly navigation. SEO is supported with canonical links, alternate hreflang tags, and Open Graph metadata. However, the lack of HTTPS and modern TLS support is a critical technical deficiency. The site uses Matomo analytics for tracking, integrated via JavaScript with cookie consent controls. Overall, the technical infrastructure is solid but requires modernization in security protocols and SSL configuration.
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.
