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

Flexmail is a Belgian-based email marketing platform established in 2003, offering services such as campaign management, personalized email marketing, and marketing automation. The website targets businesses and marketers seeking effective email marketing solutions. The platform is built using modern technologies including React and Gatsby, and integrates multiple third-party marketing and analytics tools such as Google Analytics, Hotjar, and LinkedIn Ads. The website demonstrates good design quality, mobile optimization, and SEO practices, positioning itself as a reputable player in the technology sector. Security measures include a strict Content-Security-Policy and HTTPS enforcement, contributing to a strong security posture. However, the absence of explicit privacy and cookie policies, as well as incident response contacts, indicates gaps in privacy compliance and security transparency. Overall, the website is professional and trustworthy but would benefit from enhanced privacy disclosures and incident response readiness.

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

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

Business profile

Flexmail operates as a SaaS provider in the email marketing industry, focusing on delivering tools for campaign management, analytics, and marketing automation. The company has a medium-sized presence in Belgium with a domain age dating back to 2003, indicating established market experience. The business model revolves around subscription-based software services targeting small to medium businesses and marketing professionals. The website's integration with multiple marketing and analytics platforms suggests a mature digital marketing strategy. Partnerships with services like Zapier and Iubenda enhance its ecosystem. The lack of visible contact information and privacy policies on the website could impact customer trust and regulatory compliance. Flexmail's competitive advantage lies in its localized focus and comprehensive email marketing features.

Security posture

The website employs HTTPS with an excellent SSL configuration and a robust Content-Security-Policy that restricts resource loading to trusted domains. Use of Google reCAPTCHA and absence of inline unsafe scripts indicate adherence to security best practices. However, the lack of a published security policy, incident response contacts, and vulnerability disclosure mechanisms such as security.txt reduces transparency and preparedness for security incidents. The extensive use of third-party tracking and marketing scripts increases the attack surface and privacy risks. No obvious vulnerabilities or exposed sensitive data were detected in the analyzed content. Overall, the security posture is strong technically but lacks comprehensive policy documentation and incident response readiness.

Recommendations

  1. Publish a comprehensive privacy policy and cookie policy with clear GDPR compliance statements and consent mechanisms.
  2. Implement and publicly disclose an incident response policy including security contact emails such as security@ or abuse@.
  3. Add a security.txt file to facilitate vulnerability disclosures and improve transparency.
  4. Enhance accessibility features to improve compliance and user experience for all users.
  5. Regularly review and audit third-party scripts to minimize privacy risks and potential vulnerabilities.

Technical notes

Notes

The website is built on a modern React and Gatsby framework, leveraging static site generation for performance benefits. It integrates multiple analytics and marketing tools including Google Analytics, Hotjar, LinkedIn Ads, and Zapier. The Content-Security-Policy is well-defined, restricting resources to trusted domains and using script hashes for inline scripts. The site is mobile optimized with responsive design and good SEO metadata. Hosting appears to be managed by Combell nv, consistent with WHOIS data. Performance is moderate, with potential improvements in accessibility and privacy compliance. The technical infrastructure supports a professional and scalable digital presence.
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.
