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

Rexx Systems is a well-established German technology company specializing in HR software solutions for medium and large enterprises, including cloud and on-premise offerings. With 25 years of experience and a customer base of approximately 3,000, they provide a comprehensive suite of HR, recruiting, talent management, and AI-powered tools. Their market position is strong within the HR technology sector, targeting international and enterprise clients. Technically, the website is built on WordPress with Elementor, optimized for performance and mobile responsiveness, and employs modern web technologies and SEO best practices. Security posture is solid with HTTPS, security headers, and cookie consent mechanisms, though explicit security policies and incident response information are not publicly detailed. The domain WHOIS data is missing, which raises transparency concerns despite the professional and trustworthy appearance of the website. Overall, the site demonstrates a mature digital presence with room for improvement in domain registration transparency and security disclosure.

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

6 findings rated critical or high. Fix these first.

  1. 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 Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

  3. 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.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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
  • 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

Rexx Systems operates in the B2B HR software market, offering modular and scalable solutions that cater to the needs of medium to large enterprises. Their competitive advantage lies in their long-standing market presence, extensive product portfolio, and integration of AI technologies. Revenue streams likely include software licensing, subscriptions, and professional services. The company targets HR departments and corporate clients internationally. Growth indicators include a large customer base and continuous product innovation. The partnership ecosystem includes social media engagement and use of marketing tools like Google Tag Manager and Leadinfo. Strategic observations suggest focusing on enhancing transparency around domain registration and security policies to strengthen trust further.

Security posture

The website demonstrates a good security maturity level with enforced HTTPS, presence of key security headers, and no visible exposure of sensitive data. Privacy compliance is addressed with GDPR-aligned privacy and cookie policies including consent mechanisms. However, the absence of a public incident response plan or vulnerability disclosure program limits the security transparency. The missing WHOIS data for the domain is a notable gap that could affect trustworthiness. There are no detected vulnerabilities or use of outdated libraries. Overall, the security posture is strong but could benefit from enhanced transparency and formalized security communication.

Recommendations

  1. Publish a dedicated security policy and incident response page to improve transparency.
  2. Implement and publicize a vulnerability disclosure program or security.txt file.
  3. Clarify domain registration details or ensure WHOIS data is publicly available to enhance trust.
  4. Maintain and regularly update privacy and cookie policies to stay compliant with evolving regulations.
  5. Enhance contact options for security and privacy inquiries to foster user confidence.

Technical notes

Notes

The website is built on a modern WordPress CMS platform using Elementor for page building, supported by jQuery and optimized with WP Rocket for performance. It uses CDN services for media and fonts, and integrates Google Tag Manager and Leadinfo for analytics and marketing. The site is mobile-optimized with responsive design and good accessibility features. SEO is well implemented with comprehensive meta tags, Open Graph, and JSON-LD structured data. No hosting provider details were identified from the content. Performance is fast with preloading and lazy loading techniques. Technical risks are minimal, but reliance on third-party scripts requires ongoing monitoring for vulnerabilities.
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.
