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

Litmus Software, Inc. is a well-established email marketing platform founded in 2005, offering a comprehensive suite of tools for email design, testing, personalization, analytics, and collaboration. Positioned as a leader in the email marketing technology sector, Litmus serves a broad audience of marketers and enterprises aiming to optimize their email campaigns for better ROI and subscriber engagement. The company operates under the parent company Validity and maintains offices in the USA and UK. The website reflects a mature digital presence with excellent content quality, clear navigation, and strong branding consistency. Technically, the website is built on WordPress with modern technologies including Gravity Forms, jQuery, and various analytics and marketing integrations such as Segment, Heap, Marketo, and Hotjar. The site is mobile-optimized, fast-loading, and SEO-friendly. Privacy and cookie policies are comprehensive and supported by consent mechanisms, reflecting good compliance with GDPR and related regulations. From a security perspective, the site enforces HTTPS and displays certifications like CCPA, GDPR, and SOC compliance. While explicit security headers are not fully visible in the HTML, the overall posture is strong with no evident vulnerabilities or exposed sensitive data. The absence of WHOIS data is a concern but likely due to privacy protection or query issues; however, the website's professional presentation and trust signals mitigate this risk. Overall, Litmus presents a low-risk profile with a robust business model, strong technical infrastructure, and good security and privacy practices. Continued monitoring of domain registration details and security headers is recommended to maintain trust and compliance.

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 holds a strong market position as a SaaS provider in the email marketing technology space, targeting marketing professionals and enterprises. Its competitive advantages include a comprehensive feature set covering email creation, testing, personalization, and analytics, supported by integrations with major ESPs and marketing platforms. Revenue is primarily subscription-based, with tiered pricing plans catering to different customer segments. The company demonstrates growth through continuous product updates and a strong content marketing strategy. Partnerships with Validity and integrations with industry-standard tools enhance its ecosystem. The presence of awards and customer testimonials further solidify its reputation. Operationally, Litmus maintains multiple offices and a professional support infrastructure, indicating maturity and scalability.

Security posture

Litmus exhibits a mature security posture with enforced HTTPS, privacy certifications (CCPA, GDPR, SOC), and cookie consent mechanisms. The website avoids exposing sensitive data and uses reputable third-party analytics and marketing tools. However, explicit security headers like Content-Security-Policy and X-Frame-Options are not clearly visible and should be verified. Incident response and vulnerability disclosure information are not publicly available, representing an area for improvement. The absence of a security.txt file and dedicated security contact channels limits transparency. Overall, the security maturity is good, with recommendations to enhance header policies and incident response visibility to align with best practices and compliance requirements.

Recommendations

  1. Verify and implement comprehensive security headers including CSP, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a security.txt file and provide clear incident response contact information to improve vulnerability disclosure transparency.
  3. Regularly audit third-party scripts and integrations for security vulnerabilities and privacy compliance.
  4. Enhance monitoring of domain registration details to detect any discrepancies or privacy protection issues.
  5. Continue to maintain and update privacy and cookie policies to reflect evolving regulations and best practices.

Technical notes

Notes

The website leverages a modern WordPress CMS with a well-structured theme and plugins such as Gravity Forms for data collection. It integrates multiple analytics and marketing tools including Segment, Heap, Marketo, and Hotjar, indicating a sophisticated data-driven marketing approach. Performance optimizations such as lazy loading, CDN usage, and prefetching are implemented, contributing to fast load times and good user experience. Mobile responsiveness and accessibility features are well addressed. The technical stack is robust and scalable, though continuous updates and security audits are necessary to mitigate risks from third-party dependencies.
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.
