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

Billwerk+ is a technology company specializing in subscription and payment solutions designed to help businesses grow, innovate, and optimize their operations. The company serves a medium-sized market segment with over 4000 companies and organizations empowered by its SaaS platform. The website is professionally designed, multilingual, and provides clear business descriptions and calls to action such as booking demos and free trials. Technically, the website is built on WordPress using the Avada theme, incorporating modern web technologies including jQuery, Google Tag Manager, Matomo analytics, and Borlabs Cookie for consent management. The site demonstrates good mobile optimization and SEO practices, with structured data and Open Graph metadata enhancing search engine visibility. From a security perspective, the site enforces HTTPS and implements cookie consent mechanisms, indicating GDPR compliance. No critical vulnerabilities or exposed sensitive data were detected. However, the absence of a published security policy, incident response contacts, and vulnerability disclosure mechanisms suggests room for improvement in transparency and security maturity. Overall, the domain appears legitimate despite privacy-protected WHOIS data, which is common for SaaS providers. The website presents a trustworthy and professional front with good technical and privacy compliance, making it a reliable platform for subscription management services.

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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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 Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, LinkedIn, YouTube

      What to do: Document all third-party data sharing in your privacy policy

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

Billwerk+ operates in the technology sector, focusing on subscription management and payment solutions delivered via a SaaS model. Its market positioning is solid, serving thousands of clients, which indicates a stable revenue stream and established customer base. The company targets businesses looking to transform and optimize their subscription-based revenue models. The website's multilingual support and comprehensive content suggest an international or European focus. The use of advanced marketing and analytics tools reflects a data-driven approach to customer acquisition and retention. No parent or subsidiary companies were identified, indicating an independent operation or a standalone brand within a larger group not disclosed on the site.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, cookie consent mechanisms, and no visible exposure of sensitive data. The use of Borlabs Cookie for consent management and Matomo for privacy-respecting analytics aligns with GDPR requirements. However, the lack of a dedicated security policy page, incident response contacts, and vulnerability disclosure program limits transparency and may impact trust for security-conscious clients. Security headers were not explicitly detected in the HTML content, suggesting potential improvements. Overall, the site is secure for general business use but could enhance its security culture and incident readiness.

Recommendations

  1. Publish a clear and accessible security policy outlining security practices and commitments.
  2. Provide incident response contact information such as security@ or abuse@ email addresses.
  3. Implement and publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Enhance website security headers (e.g., Content-Security-Policy, X-Frame-Options) to improve protection against common web attacks.
  5. Improve accessibility features to broaden user inclusivity and comply with standards.

Technical notes

Notes

The website is built on a robust WordPress CMS platform using the Avada theme, which is widely supported and regularly updated. It leverages modern JavaScript libraries like jQuery and integrates Google Tag Manager and Matomo for analytics and tracking, balanced with GDPR-compliant cookie consent via Borlabs Cookie. The site shows good mobile responsiveness and SEO optimization with proper meta tags and structured data. Performance is moderate, likely influenced by the use of multiple plugins and external scripts. There is no explicit hosting provider information, but the domain uses HTTPS with a valid SSL certificate. Technical debt appears low, but opportunities exist to optimize loading speed and enhance security headers for better protection.
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.
