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

Zenler is a professional SaaS platform specializing in online course creation, marketing, and community engagement. It offers an all-in-one solution targeting educators, coaches, and marketers who seek to consolidate multiple tools into a single platform. The website demonstrates a high level of digital maturity with modern technologies, responsive design, and comprehensive content. Security posture is solid with HTTPS and standard tracking tools, though explicit security headers and incident response information are lacking. Privacy and cookie policies are well implemented, indicating good compliance practices. However, the absence of WHOIS data introduces some uncertainty about domain legitimacy, warranting monitoring. Overall, Zenler presents a trustworthy and professional online presence with room for security enhancements.

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 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 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

  4. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • High

      Unregistered MX Record

      MX record points to unregistered domain: alt4.aspmx.l.googlemail.com

      What to do: Remove or fix MX record pointing to unregistered domain

      • RFC 5321 §5.1
      • NIS2 21(2)(i)
      • IR 2024/2690 12.4: Implementing Regulation (EU) 2024/2690, Annex point 12.4: Asset inventory

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

Zenler positions itself as a competitive alternative to fragmented online course tools by integrating course creation, marketing funnels, email automation, live classes, and community features. Its business model is subscription-based SaaS, targeting a medium-sized market of online educators and course creators. The platform leverages customer testimonials and Trustpilot reviews to build trust and credibility. The marketing ecosystem includes social media channels and user communities, supporting growth and customer engagement. The lack of explicit contact information on the website suggests a focus on digital self-service and automated support channels.

Security posture

The website enforces HTTPS and uses reputable analytics and marketing scripts loaded asynchronously to minimize performance impact. However, it lacks explicit security headers such as Content-Security-Policy and X-Frame-Options, which could improve protection against common web attacks. No visible vulnerabilities or exposed sensitive data were found in the HTML content. The absence of a dedicated security policy or incident response contact reduces transparency and readiness for security incidents. Privacy compliance is strong with clear policies and cookie consent mechanisms. Overall, the security posture is good but could be enhanced with additional headers and incident response information.

Recommendations

  1. Implement and enforce security headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen web security.
  2. Publish a dedicated security policy and provide clear incident response contact information to improve transparency and trust.
  3. Monitor domain WHOIS status and consider registering domain information publicly to enhance legitimacy perception.
  4. Continue maintaining comprehensive privacy and cookie policies with clear consent mechanisms to ensure ongoing compliance.
  5. Enhance contact information availability to facilitate user support and trust-building.

Technical notes

Notes

The website uses a modern tech stack including Bootstrap for responsive design, jQuery for DOM manipulation, and integrates multiple third-party services such as Google Analytics, Facebook Pixel, Microsoft Clarity, and Intercom for analytics and customer engagement. Hosting is via Amazon CloudFront CDN, ensuring fast content delivery. The site is well optimized for mobile devices and SEO with proper meta tags and Open Graph data. No CMS was explicitly detected, suggesting a custom or proprietary platform. Performance is fast with asynchronous script loading. Technical debt appears low, but security header implementation could be improved.
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.
