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

Brevo operates as an all-in-one email platform specializing in sending newsletters and transactional emails. The website sp1-brevo.net serves as a technical domain for tracking links and hosting images related to email campaigns. The company positions itself with a strong anti-spam stance and provides clear contact channels for abuse reporting. The domain is relatively new, created in 2023, and is managed with appropriate domain security statuses and Cloudflare DNS services. Technically, the website uses modern frameworks such as Bootstrap 5.1.3 and is hosted via OVH sas with Cloudflare DNS. The site is mobile optimized and loads quickly, though some security best practices like DNSSEC and security headers are not yet implemented. The website content is professional and clear but lacks cookie consent mechanisms and visible forms for data collection. From a security perspective, the site benefits from HTTPS and domain protection statuses but could improve by enabling DNSSEC and adding security headers. The presence of a clear abuse contact email and anti-spam policy indicates a mature security posture. No vulnerabilities or suspicious content were detected. Overall, the website is trustworthy and professional with a good balance of technical and business credibility. Strategic improvements in security headers, DNSSEC, and privacy compliance mechanisms would enhance the platform's security and compliance posture.

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 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
    • 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 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

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

Brevo targets businesses and marketers needing reliable email marketing and transactional email services. Its SaaS business model focuses on providing an integrated platform for email campaigns with tracking and hosting capabilities. The company emphasizes compliance and anti-spam policies to maintain market trust. The domain's recent creation aligns with a growing or newly branded service. Brevo's partnership ecosystem includes its main domain brevo.com, with no detected subsidiaries or related domains. The platform's competitive advantage lies in its all-in-one approach and strong anti-spam stance, appealing to businesses requiring compliant email marketing solutions.

Security posture

Brevo demonstrates a solid security foundation with HTTPS enforcement and domain registration protections. The availability of an abuse contact email and anti-spam policy reflects a proactive security culture. However, the absence of DNSSEC and security headers such as Content-Security-Policy and Strict-Transport-Security represents areas for improvement. No exposed sensitive data or vulnerabilities were found. The lack of a vulnerability disclosure policy or security.txt file suggests room to enhance transparency and incident response readiness. Overall, the security posture is good but could be elevated with additional technical controls and formalized disclosure mechanisms.

Recommendations

  1. Enable DNSSEC to protect against DNS spoofing and improve domain security.
  2. Implement security headers including Content-Security-Policy, X-Content-Type-Options, and Strict-Transport-Security.
  3. Add a cookie consent mechanism to comply with privacy regulations and improve user transparency.
  4. Publish a vulnerability disclosure policy or security.txt file to enhance incident response and transparency.
  5. Consider adding more comprehensive contact information such as phone numbers or physical addresses to improve business credibility.

Technical notes

Notes

The website uses a modern and lightweight tech stack, including Bootstrap 5.1.3 for responsive design and Cloudflare for DNS management. Hosting is provided by OVH sas, a reputable provider. The site loads quickly and is mobile optimized, though accessibility features are basic. SEO optimization is minimal but sufficient for the domain's technical purpose. No CMS or complex frameworks were detected, indicating a simple, focused implementation. The absence of security headers and DNSSEC are technical gaps that should be addressed to reduce risk. Overall, the technical infrastructure is solid but could benefit from enhanced security and privacy features.
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.
