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

SINN Consulting GmbH is an Austria-based international consulting firm specializing in SAP BRIM solutions, focusing on industries such as telecommunications, energy, online retail, transport, media, and insurance. The company holds a reputable market position as a SAP Gold Partner and offers a comprehensive portfolio of SAP-related consulting and implementation services. Their website reflects a professional and consistent brand image targeting enterprise and medium-sized clients primarily in Austria and Germany. Technically, the website is built on WordPress with modern plugins and technologies, supporting multilingual content and GDPR compliance. However, a critical security gap exists due to the absence of a valid SSL certificate, despite the presence of HSTS headers, which undermines the security posture. Privacy compliance is well addressed with cookie consent mechanisms and a detailed privacy policy. Overall, the site demonstrates good business credibility and user experience but requires urgent security improvements to enable HTTPS 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
    • Critical

      Critical Service Exposed: PostgreSQL

      Port 5432 (PostgreSQL) is publicly accessible - PostgreSQL - Database server

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

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 leverages its SAP Gold Partner status and extensive experience to serve multiple sectors with SAP BRIM and related modules. Their business model centers on consulting and project implementation, targeting large and medium enterprises in Austria and Germany. The website showcases a strong partnership ecosystem with SAP and notable client references, indicating a stable market presence. Their multilingual support and GDPR compliance reflect maturity in addressing regional regulatory requirements. The absence of terms of service and incident response contact points suggests areas for further business process maturity. Marketing and analytics tools like Google Tag Manager and Facebook Pixel are used moderately, supporting data-driven insights while maintaining privacy compliance.

Security posture

The website's security posture is weak due to the lack of HTTPS, which is a critical vulnerability. While some security headers like HSTS are present, they are ineffective without SSL. No major vulnerabilities or malware indicators were found, and the site uses updated plugins and libraries. The cookie consent mechanism aligns with GDPR requirements, but the absence of incident response contacts and security policies limits transparency. The site should prioritize SSL installation, enhance security headers, and implement incident response disclosures to improve overall security maturity.

Recommendations

  1. Install and properly configure a valid SSL/TLS certificate to enable HTTPS across the entire site.
  2. Enhance security headers by adding Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Publish a clear security policy and incident response contact information to improve transparency and trust.
  4. Regularly audit and update all plugins and themes to mitigate potential vulnerabilities.
  5. Maintain and improve GDPR compliance by ensuring all data collection and retention policies are clearly documented.

Technical notes

Notes

The website is built on a modern WordPress platform with a well-structured theme and uses popular plugins such as Contact Form 7, WPML for multilingual support, and GDPR Cookie Compliance for privacy management. The use of lazy loading and image optimization plugins indicates attention to performance, although no explicit performance metrics were available. The site is hosted on an Apache server with DNS managed by easyname.eu. The absence of SSL negatively impacts security and user trust. The technical stack is standard for professional consulting firms, but improvements in security infrastructure and performance monitoring are recommended.
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.
