Risk levelLow

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

Litmus is a well-established enterprise SaaS company specializing in email marketing platforms that provide comprehensive tools for email testing, analytics, and campaign optimization. The website demonstrates a mature digital presence with extensive use of marketing and analytics technologies, including Google Analytics, Hotjar, and Visual Website Optimizer. The platform targets marketing teams and enterprises seeking to improve email campaign effectiveness. Technically, the site is built on WordPress with modern JavaScript libraries and integrates multiple third-party services for marketing and analytics. Security posture is solid with HTTPS enforced and no exposed sensitive data, though explicit security headers are not clearly present and no public security or incident response policies were found. WHOIS data is incomplete, lacking registrar and registrant details, which is unusual but the website's professionalism and digital footprint support its legitimacy. Overall, the site is high quality, secure, and business credible, with room for improvement in transparency around security policies and WHOIS data.

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.

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

Litmus operates in the technology sector, focusing on email marketing solutions delivered via a SaaS model. Its market position is strong, serving enterprise clients with advanced email testing and analytics capabilities. The business model relies on subscription revenue from marketing teams and enterprises. The company leverages partnerships with major ad networks and analytics providers, indicating a robust marketing ecosystem. The website content and structure reflect a professional and consistent brand image, targeting marketing professionals and teams. Growth indicators include extensive use of analytics and marketing automation tools. No parent or subsidiary companies were identified from the data provided.

Security posture

The website enforces HTTPS and integrates multiple tracking and marketing scripts securely. However, explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options are not evident in the HTML source, which could be improved to enhance security. No vulnerabilities or exposed sensitive data were detected. The absence of published security policies, incident response contacts, or vulnerability disclosure mechanisms suggests a gap in security transparency and readiness. GDPR compliance is indicated by the presence of privacy and cookie policies with consent mechanisms. Overall, the security posture is good but could benefit from enhanced security header implementation and public security documentation.

Recommendations

  1. Implement and publish explicit security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen browser security.
  2. Publish a dedicated security policy and incident response page to improve transparency and readiness.
  3. Establish and publicize a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  4. Review WHOIS registration details to ensure accurate and complete domain registration information is publicly available.
  5. Enhance accessibility features and conduct regular security audits to maintain high security and compliance standards.

Technical notes

Notes

The website is built on WordPress CMS with a custom theme and uses jQuery and Gravity Forms for interactive elements. It integrates multiple third-party marketing and analytics tools such as Google Analytics, Hotjar, Segment, and Visual Website Optimizer, indicating a sophisticated marketing technology stack. The site uses CDN services like Cloudfront for content delivery, improving performance. Mobile optimization is good, and SEO is enhanced by Yoast SEO plugin. Performance is moderate, with potential for improvement in load times and accessibility. The technical infrastructure is modern and supports enterprise-level marketing operations, though some technical debt may exist in the form of missing explicit security headers and potential over-reliance on multiple third-party scripts.
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.
