Risk levelMedium

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

Sendinblue operates the domain img.mailin.fr as a technical domain to support its email marketing and transactional email services. The website content confirms its use for tracking links and hosting images related to emails sent by Sendinblue customers. The domain WHOIS data is unavailable, which is common for technical or internal-use domains managed by registries like AFNIC. Despite this, the website content and links to official Sendinblue resources establish legitimacy and trust. Technically, the site uses modern frameworks such as Bootstrap 5.1.3 and is mobile optimized with a clean, professional design. However, it lacks visible security headers and cookie consent mechanisms, which are recommended for compliance and security hardening. No forms or tracking scripts are present, indicating minimal data collection and user interaction. From a security perspective, the site benefits from HTTPS and does not expose sensitive data. The presence of a clear abuse contact and anti-spam policy reflects a proactive security posture. The absence of WHOIS data reduces transparency but does not detract significantly from trust due to the domain's technical nature and association with a reputable company. Overall, the domain and website serve a specialized function within Sendinblue's infrastructure. The risk is low, but improvements in security headers and privacy compliance would enhance the security posture and user trust.

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. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • 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

  2. 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
  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

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

Sendinblue is a large technology company specializing in email marketing and transactional email services. The domain analyzed is a technical subdomain used for email tracking and image hosting, integral to Sendinblue's SaaS business model. The company targets businesses and marketers who require reliable email delivery and analytics. The website content and links indicate a mature business with established policies against spam and abuse. The lack of WHOIS transparency is typical for such technical domains but should be monitored. Sendinblue's market position is strong, with a focus on compliance and customer support, as evidenced by clear abuse reporting channels and privacy policies.

Security posture

The security posture of the domain is moderate. HTTPS is used, ensuring encrypted communications. The site includes an abuse contact email and references a zero tolerance spam policy, indicating operational security awareness. However, the absence of security headers such as Content-Security-Policy, X-Frame-Options, and others is a gap. No vulnerability disclosure or security.txt file is present, limiting transparency for security researchers. No forms or user inputs reduce attack surface. Overall, the domain is low risk but could benefit from enhanced security best practices and compliance features.

Recommendations

  1. Implement standard security headers (CSP, X-Frame-Options, X-Content-Type-Options) to improve security posture.
  2. Add a cookie consent mechanism to comply with privacy regulations and improve user trust.
  3. Publish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  4. Enhance WHOIS transparency if possible or provide clear documentation explaining domain registration status.
  5. Regularly review and update abuse and privacy policies to maintain compliance and trust.

Technical notes

Notes

The website uses Bootstrap 5.1.3 for responsive design and standard HTML5 and CSS3 technologies. The site loads external CSS from jsdelivr CDN. No JavaScript libraries or analytics scripts were detected, indicating a lightweight and minimal technical footprint. The site is mobile optimized and has a clean layout but lacks advanced SEO and accessibility features. Hosting provider details are not disclosed. Performance is moderate given the minimal content. The technical setup is appropriate for a technical domain serving static content related to email services.
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.
