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. 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

      • 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
    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • 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

  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.

    • 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 · 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

ChatWerk positions itself as a niche player in the business messaging SaaS market, leveraging popular messenger platforms to provide unified communication tools. Its business model is subscription-based SaaS, targeting SMEs and sales/customer service teams. The company emphasizes GDPR compliance as a competitive advantage. The website content and metadata reflect a consistent brand and clear value proposition. The use of multilingual support via WPML suggests readiness for broader European markets. The lack of visible certifications or security policies indicates room for growth in trust signals. The company maintains active marketing through Facebook and Google Ads, supporting lead generation and brand awareness.

Security posture

The website enforces HTTPS and uses security and performance plugins such as Borlabs Cookie for consent management and Perfmatters for optimization. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, some common security headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options are not explicitly present, which could improve defense in depth. Forms appear to be protected with CAPTCHA and anti-bot measures. Incident response and vulnerability disclosure policies are not publicly available, which is a potential compliance gap. Overall, the security posture is good but could be enhanced with additional headers and documented policies.

Recommendations

  1. Implement and enforce comprehensive HTTP security headers including CSP, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a formal incident response and vulnerability disclosure policy to improve transparency and compliance.
  3. Regularly audit and update WordPress core and plugins to mitigate vulnerabilities.
  4. Enhance accessibility features to improve compliance and user experience for all users.
  5. Consider obtaining and displaying relevant security certifications or trust badges to strengthen market trust.

Technical notes

Notes

The website is built on WordPress CMS using a combination of popular plugins such as WPBakery Page Builder, Yoast SEO, WPML for multilingual support, and Redux Framework. It leverages a CDN (chatwerk.b-cdn.net) for static content delivery, improving performance and availability. JavaScript libraries include jQuery and Owl Carousel for UI components. The site is mobile optimized with responsive design and good SEO metadata. Performance is moderate with room for improvement in loading speed and accessibility. The technical stack is modern and well-maintained, suitable for a SaaS business website.
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.
