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

Flexmail is a Belgian-based e-mail marketing platform established in 2003, offering software solutions for effective and personalized e-mail campaigns, analytics, and marketing automation. The website is professionally designed using modern technologies such as React and Gatsby, integrating multiple marketing and analytics tools to support business growth. Security measures include a strong Content-Security-Policy and HTTPS usage, reflecting a good security posture. However, the absence of visible privacy and cookie policies and explicit contact information slightly reduces privacy compliance and user trust. Overall, the domain registration data aligns well with the website's business claims, indicating a legitimate and trustworthy entity.

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

      • 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 operates in the technology sector, specifically targeting small business owners and marketers in Belgium with SaaS e-mail marketing solutions. The company benefits from a long-established domain and consistent registrant information, positioning itself as a reliable player in the Belgian market. The website's integration with major advertising and analytics platforms suggests a mature marketing ecosystem. The business model focuses on subscription-based software services with key offerings including campaign management, reporting, and automation. No subsidiaries or partner domains were identified beyond common marketing platforms.

Security posture

The website demonstrates a solid security posture with HTTPS enabled and a comprehensive Content-Security-Policy restricting resource loading to trusted domains. No critical vulnerabilities or exposed sensitive data were detected. The use of multiple third-party scripts necessitates ongoing security audits to mitigate risks. The lack of explicit security or incident response policies on the site is a gap in transparency. Overall, security practices are good but could be enhanced with additional headers and published policies.

Recommendations

  1. Publish a comprehensive privacy policy and cookie policy with clear GDPR compliance statements.
  2. Implement a cookie consent mechanism to comply with privacy regulations.
  3. Add explicit contact information including company emails and phone numbers for support and sales.
  4. Enhance security headers by adding X-Frame-Options and X-Content-Type-Options.
  5. Regularly audit third-party scripts and update accessibility features to improve compliance.

Technical notes

Notes

The website is built on a modern React and Gatsby stack, ensuring good performance and SEO optimization. Hosting and domain registration are managed by Combell nv, a reputable Belgian provider. The site uses multiple analytics and marketing tools including Google Analytics, Hotjar, Facebook SDK, LinkedIn Ads, and Zapier integrations. Performance is moderate with good mobile optimization. Accessibility is basic and could be improved. The site uses strict Content-Security-Policy headers to mitigate risks from third-party scripts. Overall, the technical infrastructure is solid with room for enhancements in accessibility and privacy compliance.
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.
