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

3 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.

    • 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. 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

SendGrid operates in the technology sector, focusing on email delivery and marketing solutions. Its business model is SaaS-based, targeting developers, marketers, startups, enterprises, and high-volume senders. The company benefits from Twilio's ecosystem, enhancing its market position and reach. Key services include Email API, SMTP service, email validation, deliverability insights, and marketing automation. The website showcases strong customer trust through logos and case studies. The presence of extensive documentation, resources, and professional services indicates a mature and customer-centric approach. Strategic partnerships and integration with Twilio's platform further strengthen its competitive advantage.

Security posture

The website exhibits a mature security posture with enforced HTTPS, domain status locks preventing unauthorized transfers or deletions, and integration of GDPR-compliant consent management via TrustArc. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, DNSSEC is not enabled, which could be improved to enhance DNS security. The absence of publicly available incident response or vulnerability disclosure policies suggests an area for transparency improvement. Overall, the site follows best practices in web security and privacy compliance, supporting user trust and regulatory adherence.

Recommendations

  1. Enable DNSSEC to improve DNS security and prevent spoofing.
  2. Publish explicit incident response and vulnerability disclosure policies to enhance transparency.
  3. Consider adding security framework certifications (e.g., ISO 27001) information publicly to boost trust.
  4. Regularly audit and update third-party scripts to mitigate potential vulnerabilities.
  5. Implement additional security headers such as Content-Security-Policy and X-Content-Type-Options if not already present.

It uses Adobe Helix RUM for real user monitoring, indicating a focus on performance and user experience. The site is mobile-optimized, accessible, and SEO-friendly with proper meta tags and structured data.

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.
