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

Trenkwalder Group AG is a large, established HR services provider operating across multiple European countries. The company offers a range of services including HR service, outsourcing, and technology solutions, targeting both job seekers and corporate clients. Their digital presence is supported by modern web technologies such as Next.js and Storyblok CMS, hosted likely on Microsoft Azure infrastructure. The website is professionally designed with good content quality and clear navigation, supporting multiple languages and country-specific domains. However, the absence of a valid SSL certificate and HTTPS support is a critical security gap that undermines user trust and data protection. Security headers are well implemented but cannot compensate for the lack of encryption. Privacy compliance is partial, with a privacy policy present but no cookie consent mechanism or terms of service detected. The company maintains a strong social media presence and provides clear contact information, enhancing business credibility. Overall, the website demonstrates moderate digital maturity but requires urgent security improvements to meet modern standards.

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

4 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

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • 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

  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

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

Trenkwalder Group AG holds a solid market position as a multinational HR service provider with a broad European footprint. Their business model focuses on staffing and outsourcing services, leveraging localized country domains to address regional markets effectively. The company benefits from a comprehensive partnership ecosystem, including related domains and specialized branches such as Trenkwalder SportsAustria. Revenue streams likely derive from service contracts with corporate clients and recruitment fees. The website's multilingual support and professional branding indicate a mature marketing approach targeting both candidates and companies. Growth indicators include extensive country coverage and active social media engagement. Strategic observations suggest opportunities to enhance trust through improved security and privacy compliance, which could strengthen competitive advantage.

Security posture

The current security posture of the Trenkwalder website is moderate but with significant vulnerabilities. While security headers such as Content Security Policy, X-Frame-Options, and X-Content-Type-Options are properly configured, the lack of a valid SSL certificate and absence of HTTPS severely compromise data confidentiality and integrity. No TLS protocols are enabled, and critical features like OCSP stapling and session resumption are missing. There is no evidence of a security policy, incident response contacts, or vulnerability disclosure mechanisms, indicating limited security governance transparency. GDPR compliance is partial, with a privacy policy present but no cookie consent or terms of service. The overall risk is elevated due to the potential for data interception and user distrust. Immediate remediation of SSL/TLS issues and enhancement of privacy controls are recommended to improve security maturity.

Recommendations

  1. Install and maintain a valid SSL/TLS certificate to enable HTTPS across all domains.
  2. Enable modern TLS protocols (TLS 1.2 or higher) and implement OCSP stapling for improved security.
  3. Deploy a cookie consent mechanism to comply with GDPR and enhance user privacy transparency.
  4. Publish clear terms of service and security policies including incident response contacts.
  5. Regularly audit and update security headers and monitor for vulnerabilities in third-party libraries.

Technical notes

Notes

The website is built on a modern technology stack featuring Next.js and React, with content managed via Storyblok CMS. Hosting appears to be on Microsoft Azure, inferred from the IP address. The site supports multiple languages and country-specific domains, indicating a scalable and modular architecture. However, performance metrics are missing, and inferred load time is slow, suggesting optimization opportunities. Accessibility is basic, with room for improvement in compliance with standards. SEO is well addressed through meta tags and Open Graph data. The absence of HTTPS and valid SSL certificates is a critical technical debt that impacts security and user trust. Overall, the infrastructure is modern but requires urgent security upgrades and performance tuning to enhance reliability and user experience.
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.
