Low risk. 1 critical or high finding in SSL/TLS.

Security score

Risk levelLow

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

Flexmail is a well-established Belgian email marketing platform founded in 2003, offering a comprehensive SaaS solution for campaign management, marketing automation, and CRM segmentation. The website presents a professional and modern design built on React and Gatsby, integrating multiple marketing and analytics tools such as Google Analytics, Hotjar, and Facebook Pixel. Security posture is strong with strict Content-Security-Policy headers and HTTPS enforcement. However, the absence of visible privacy and cookie policies, as well as contact information, reduces privacy compliance and business credibility scores. Overall, the site is accessible, trustworthy, and technically sound but would benefit from enhanced transparency and compliance documentation.

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

1 finding rated critical or high. Fix these first.

  1. 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

Flexmail targets small business owners and marketers in Belgium, positioning itself as a leading email marketing software provider. The business model is SaaS-based, focusing on delivering effective and personalized email campaigns with analytics and automation capabilities. The company leverages partnerships and integrates with various third-party marketing platforms. The website content and metadata emphasize professionalism and market leadership in the Belgian email marketing sector.

Security posture

The website demonstrates a mature security posture with HTTPS, strict Content-Security-Policy, and no detected vulnerabilities or exposed sensitive data. However, there is no public security policy or incident response information available, and no vulnerability disclosure or security.txt files were found. The site uses multiple third-party scripts which require ongoing monitoring for security risks. Overall, security best practices are followed but transparency and incident readiness could be improved.

Recommendations

  1. Publish comprehensive privacy and cookie policies with explicit consent mechanisms to improve GDPR compliance.
  2. Add clear contact information including support emails and phone numbers to enhance business credibility.
  3. Implement and publish a security policy and incident response plan to build trust and preparedness.
  4. Consider adding a vulnerability disclosure policy and security.txt file to encourage responsible reporting.
  5. Enhance accessibility features to improve inclusivity and compliance with accessibility standards.

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.
